What Is Included in a St Helens House Rewire?
Eight circuits, 22 double sockets and 9 light points, plus everything below, all in the price you were quoted. Nothing here is an extra.
What a full rewire gives you in each room
The standard allocation in a 3-bed St Helens house, before you add a thing. Most quotes give you a price and leave you guessing.
All on new Prysmian cable into a new Contactum board, tested and certified on the day we finish.
See exactly what we fit and why
Prysmian cable. The part nobody sees and the part you cannot change later without doing the whole job again.
Hager Sollysta. Our standard white range, on every socket, switch and pendant, so the house matches throughout.
Contactum Defender 2.0. Metal board with its own breaker, an RCBO, on every single circuit rather than one shared trip, so a fault in the kitchen does not take the lights out upstairs. Surge protection fitted as standard. Type A devices as standard, which matters because Type A picks up the DC leakage that EV chargers, induction hobs and LED drivers produce and older Type AC devices can miss.
What Does a Rewire Actually Look Like?
Eight circuits, 22 double sockets and 9 light points, laid over a typical 3-bed St Helens house. Tap any point to see what it is. Nothing here is an extra, it is all in the price.
Your house will not be laid out exactly like this one, and the counts shift a little with the layout. What does not shift is the principle: every room gets its full allocation as standard, and anything on top of it is priced on your quote before we start. See what extras cost.
That is the standard spec on a typical house. Yours will differ a little, and we will count it properly at the free survey.
Because you should not have to give a stranger your phone number to find out what a job costs. Most rewire quotes arrive as one number with nothing behind it, so you cannot tell what is in it, what is missing, or what you are being charged for the bits you asked to add. We have put the base price, the room by room allocation and every single extra on the page instead.
What Would Your St Helens Rewire Cost?
£4,500 for a 2-bed, £5,000 for a 3-bed and £5,500 for a 4-bed, and that base price is everything you just read: 8 circuits, 22 double sockets, 9 light points, the new board, the alarms and the certificate. Pick your house below, then add the extras people most often want on top.
- New Contactum board with its own breaker per circuit, so one fault does not kill the whole house
- Prysmian cable and Hager Sollysta accessories throughout
- 2 smoke alarms plus a kitchen heat detector
- Bathroom extractor fan
- NICEIC certificate on the day we finish
A real starting figure, not a teaser. Once the job passes £6,000, every point after that goes on at £60 instead of £80. We do not backdate it, so the points that got you to £6,000 stay at £80. This works the split out for you. The only other thing that moves it is access we would spot at the survey, like solid walls or floors that will not lift.
That is the standard allocation. Want us to walk your actual house and count it properly?
Full Rewire vs Partial Rewire: Which Do You Need?
A full rewire replaces every circuit in the house. A partial replaces only the circuits that have failed, and for a lot of St Helens houses that is the honest answer. Here is how to tell which one you are looking at.
Everything Replaced
The whole house. Every cable, socket, switch, light point and the fuse box, all replaced. Takes 2 to 5 days depending on the size of the place, and you get a certificate covering the entire installation.
- Wiring has never been replaced
- An EICR came back with several failures
- You are renovating or extending anyway
- You are about to sell and want it settled
- Sorted for the next 25 years
Problem Circuits Only
Only the circuits that have failed or been condemned on an EICR get replaced. Sound wiring stays where it is. Most partial rewires in St Helens take 1 to 2 days and cost a fraction of the full job.
- Only one or two circuits failed the EICR
- Some of the house was done at some point
- You need it safe now and the rest can wait
- Cheaper today, though you may finish it later
- Not an option if the cable is rubber or brittle
What Is the Difference Between a Standard and a High Spec Rewire?
Standard gives every room a centre light on one switch. High spec is about control: more than one set of lights in a room, each on its own switch, so you are not stuck turning everything on at once.
In a standard house you walk into a room, hit one switch and every light comes on. High spec means separate switching. The spots over the worktop, the strip under the cupboards and the centre light are three different sets on three different switches. You use what you need. That is what people mean when they say a room can be set for different moods, and it is decided at first fix, not afterwards.
See that priced up on a real quote
That is £1,090 on top of the standard price, and every one of those sets works independently. Commit to a package that size and the point rate drops from £80 to £60, which is already reflected above.
Price Your Own VersionThe kitchen questions people wish they had answered first
Over 80 rewires in, the kitchen is what people say they wish they had thought harder about. Once the walls are shut it is a much bigger job to change your mind.
- Do you have enough sockets above the worktop?
- Is there a USB-C socket for phones and tablets? It is £20 to £25 for the plate and no labour on top.
- Space for kettle, toaster and coffee machine without sharing a socket?
- Would you prefer spotlights instead of a single pendant?
- Where will the cooker or hob be positioned?
- Where does the fridge-freezer go?
- Having an island? You will need floor sockets.
- Induction hob? Needs its own dedicated isolation switch.
Decide this before first fix. Once the cable is in and the walls are closed, adding a separate switch means lifting floors again. It costs nothing to change your mind on the walk-around, which is exactly why we do one.
Not sure which of these are worth it in your house? We will tell you straight at the survey, including when they are not.
What Do Rewire Extras Cost in St Helens?
Extra sockets are £80, extra light points £80, spotlights £60, extra switches £60, an electric shower circuit £350 and an EV charger circuit £400. These are the real prices off our last 20 rewire quotes, and everything you add appears on your written quote before we start.
Sockets
| Extra double socket, anywhere | £80 |
| Outdoor weatherproof double socket | £100 |
| Kitchen island socket | £80 |
| Loft or cupboard socket | £80 |
| TV point with aerial and HDMI behind the wall | £80 |
| USB-C socket face instead of a standard one | £20 to £25 |
Upgrading a faceplate costs you the plate and nothing else. A USB-C socket beside the bed or on the kitchen worktop is the same job for us as a standard one, so we do not add labour for it. You pay the difference between that plate and the standard white Sollysta one we would have fitted anyway, which is usually £20 to £25.
Lighting
| Extra light point, we supply the fitting | £80 |
| Extra light point, you supply the fitting | £70 |
| Extra spotlight | £60 |
| Wall light | £80 |
| LED strip or under-cabinet, labour per metre | £50 |
| Loft light and switch together | £140 |
| Front outdoor light, we supply | £100 |
| Garden light, we supply | £100 |
| Floodlight that comes on when it senses movement, with a switch inside to override it | £100 |
Switches
| Extra switch position | £60 |
| Work one light from two places, per extra switch | £60 |
| Multi-gang switch, 2, 3 or 4 gang | £60 |
No upcharge for gang count. One plate can switch four lights for the same £60.
Circuits and big items
| Electric shower circuit, 6mm, up to 8.5kW | £350 |
| Electric shower circuit, 10mm, 9.5kW and above | £425 |
| Electric towel radiator supply | £120 to £160 |
| Loft circuit ready for a future conversion | £150 |
| Extra bathroom fan, reusing the existing hole | £160 |
| Extra bathroom fan, new core hole and ducting | £320 to £350 |
| Bigger fuse board, 13 ways instead of 10, so there is room to add circuits later | £100 |
| Board moved, with isolator and 16mm supply | £350 to £500 |
| EV charger circuit, and we fit your charger if you supply it | £400 |
Whole rooms beyond the standard 3-bed layout
| Downstairs toilet, light and switch | £140 |
| Utility room or corridor, light, switch and socket | £220 |
| Front porch, two lights, socket and switch | £240 to £300 |
| Big storage cupboard, two sockets, light and switch | £300 |
| Dining extension, two sockets, centre light and a switch at each end | £360 |
| Home office, four sockets, light and switch | £380 |
| Ensuite, three spots, shower circuit, fan and towel rail | £900 to £1,175 |
Our standard point rate is £80. Once your job passes £6,000, every point after that goes on at £60, because the extra work is far easier while we are already on site with the floors up. We do not backdate it, so the points that got you to £6,000 stay at £80, but everything beyond it is cheaper. You do not have to ask, it comes off automatically. Same if you change your mind mid-job: additions during the rewire go on at £60, not £80. Moving a socket or a light before first fix costs nothing at all, which is the whole reason we walk the house with you on day one.
What We Throw In
Every one of those prices goes on your written quote before we start. Nothing gets added later.
Can You Rewire an Outbuilding or Garden Room?
Yes. We run steel wire armoured cable from your main board out to the building, and it then gets its own consumer unit and its own circuits. Garden rooms, garages, workshops, home offices and annexes, and it is worth doing while the floors are already up.
We run steel wire armoured cable, SWA, from your main consumer unit out to the building. Armoured because it is going outside and often underground, where ordinary cable has no business being.
Once the supply is there, the outbuilding is treated as an installation in its own right. It gets its own consumer unit rather than hanging off a socket in the house, which is what you usually find when someone has done it on the cheap.
Normally a lighting circuit, a socket circuit and a heating circuit as a minimum. More if the building needs them, and that depends entirely on what you are using it for.
What people use them for
What people use them for
Because there is not an honest one to give. What decides the cost is how far the building is from your board, how many circuits it needs and what you are using it for. On the route: we clip the armoured cable direct using cable cleats, along a wall or a fence line, and that is included. We do not dig trenches. If you would rather the cable was buried you are free to get a groundworker in to dig it, and we will run it either way, it makes no difference to us. Twenty metres across a lawn and five metres round the side of a garage are different jobs. We measure it at the free survey and give you a fixed price like everything else, and it goes on the same quote as the rewire.
Doing it alongside the rewire is cheaper than doing it later. The board is already coming out, the floors are already up, and we are already on site. Coming back in two years means starting again.
What Happens After You Book a Rewire?
A fixed written quote, then a 50% deposit, then the balance only once your certificate is in your hand. Here is the whole process and everything you are covered by.
We go through the house with you, room by room, and agree exactly where everything goes. Costs nothing and you are not committed to anything.
Every item priced separately, every free inclusion listed. Not a single number with nothing behind it.
Secures your start date and covers the materials order. Nothing else is due until the job is finished.
2 to 5 days depending on the size of the house. Monday to Friday, 8:30am start, never weekends.
Your NICEIC Electrical Installation Certificate is issued on the final day. The remaining 50% is due once you have it, not before.
A rewire is notifiable work under Part P of the Building Regulations. As an NICEIC Approved Contractor we self-certify it and notify building control ourselves, so you never deal with the council.
Ten years on our own workmanship. If anything we installed is not right in that time, you ring us and we come back and put it right at our cost. It runs four years longer than the NICEIC backstop below, and it is separate from it.
We are fully insured on every job. Ask to see the certificate and we will send it over before we start.
Hager and Prysmian both warranty their own products. Those warranties are yours, and we will tell you which apply to what we have fitted.
You will see electricians claim all their work is covered by it. That is not quite what it is. Platinum Promise is NICEIC's backstop for if the contractor who did the work has stopped trading. It covers up to £25,000 on any one installation for six years from completion, and NICEIC will send another registered contractor to put it right. It is real protection and worth having. It is just not a substitute for us coming back ourselves, which is what we would do.
What happens in year three?
What happens if something goes wrong in year three
Here is a way to think about the ten years. A rewired owner-occupied home should have its next EICR around ten years after the work. So our guarantee runs right up to the point your installation is next due an inspection. If anything we did was going to give trouble, it will have shown itself long before then, and it will have been our problem, not yours.
What Is It Like Living Through a House Rewire?
Your power is off from day one until we finish, and it takes 2 to 5 days rather than the 5 to 10 most guides quote. Here is exactly what each of those days looks like, so you can plan around it instead of guessing.
The free survey
We walk every room with you and agree where the sockets go, where the lights go and what you want that you have not got now. You get a fixed price in writing. Nothing starts until you say so.
First fix starts. Power off at 8am.
We start at 8:30am. Dust sheets down, furniture moved back, floorboards up. The old wiring starts coming out, and from this point nothing in the house works until we finish. We fit one temporary socket at the meter for your extension lead before anything else. This is the loudest, dustiest day of the job and there is no getting round that.
New cable through the house
Cables run through floors, walls and ceilings. Walls chased where a cable has to be buried. Back boxes go in for every socket and switch. We work room by room so you are never without the whole house at once.
Second fix. It starts looking like a house again.
Sockets, switches and light fittings all go on. The new consumer unit goes in and every circuit is connected to it. Mains smoke alarms fitted and linked. The mess stops on this day.
Tested, certified, full power back
Every circuit tested to BS 7671 and the results written up. Your NICEIC certificate is issued the same day and the job is notified to building control for you. We hoover through and take the rubbish with us.
Some firms will tell you they switch your power back on every night. They cannot. Once the old wiring is disconnected there is nothing to switch back on, and every socket, switch and light in the house is dead until the new installation is tested.
What the temporary socket will and will not run
Plenty of people still live in the house through it, and if that is you, plan for cold showers or a few nights elsewhere. Full mains power comes back on the day we test and certify, and everything works from that moment.
If you can stay with family for the whole job, do it. It is easier for you and quicker for us. If you are staying put, plan for no hot water, no heating and takeaways rather than cooking, and think hard about it if you have young kids or someone in the house who feels the cold. Over 80 rewires in, that is the advice we give everyone and it has not changed.
How Do You Know If Your House Needs Rewiring?
Most of the time it comes down to age and load. A house wired decades ago was built for a kettle, a telly and a couple of lamps, not an oven, a dishwasher and half a dozen chargers. Electrical Safety First says anything over 25 years old should be inspected. Spot any of these and book a free survey.
- Old Fuse BoxPull-out wire fuses and no RCD. If that is what you have, the rest is likely as old
- Burning SmellFrom any socket or switch. Turn the power off and ring someone today
- Failed EICRC1 or C2 codes on your report. We can tell you if a partial would clear them
- Keeps TrippingGoing off with no obvious cause, or the same circuit every time
- Lights DipThey dim when the kettle or washing machine kicks in
- Skirting SocketsSockets mounted on skirting boards indicate original wiring
- 25 Years or OlderProperty not electrically updated since the year 2000 or earlier
- Not Enough SocketsRelying on extension leads daily throughout the property
The three in red mean ring someone today. The rest mean book a survey. We will give you a straight answer, including if the answer is that you do not need one yet.
What Do St Helens Customers Say?
Six verbatim Google reviews, every one of them from a full house rewire. Trimmed for length in places, never reworded.
It is super helpful having the standard pricing for house rewiring, so you know exactly what to expect on your invoice. Optional upgrades of extra sockets, outside lights, and USB sockets, etc. were very fairly priced and easy to add-on too. They even fit an EV charger for me at a very reasonable price too.
Gave Us Final Say On Everything, Let Us Choose How Many Sockets And Where We Wanted Them. Kept Us Updated Throughout And Completed The Full Rewire With New Consumer Unit In Double Quick Time. Really Courteous, Respectful Service, Left My House Tidy Afterwards
They gave a firm timeline for completion and even completed the job before the time given. The lads that came round were lovely and courteous, and had kept the overall damage of chases to a minimum and even recommended further traders for any follow up works besides the electrical stuff. Only wish I had that spare kettle ready for them during their work.
Read three more rewire reviews
Michael and his team done a full rewire to the highest standard within 3 days. I was extremely impressed with the work and they even cleaned up after themselves. I received a certificate straight away. I would definitely use Michael and his team again in the future.
The standard of work was amazing, excellent communication. They carried out the work with the least disruption and mess as they could, I would say they cleaned my kitchen better than me! They also fitted smoke alarms which I didn't expect.
They explained the work, quoted for all the jobs we wanted doing and explained the timeline and how the work would be carried out. We were able to arrange for the rewire to be carried out while we were away on holiday to minimise the disruption. Following the rewire we received our installation certificate and excellent aftercare.
Six real rewires and what they actually came to
These are invoice totals, not estimates, anonymised to initials. Only the first is in the St Helens borough. We have included the others because they show the honest spread: the same standard specification, priced the same way, and what moves the number is the size of the house and what people chose to add.
See all six jobs and what they came to
The gap between £5,290 and £13,550 is not a different rate card. It is a small house with the standard spec at one end, and a large house with data cabling and a fully wired outbuilding at the other. Build your own on the calculator and you will land somewhere on that line.
A £3,500 quote exists locally. Ask what is in it. Ours includes the consumer unit, surge protection, mains smoke alarms, a bathroom extractor fan and the certificate, which is what cheaper quotes leave out and add later. The national firms want £6,500 upwards for the same job. We sit in the middle on purpose.
Who actually turns up?
You will notice the same names keep coming up in those reviews. Michael runs the business and quotes the jobs. The two Toms lead most of the rewires, and between them they have done the large majority of the 80 plus we have completed. It is the same faces on day one and on the day you get your certificate, not a different subcontractor every morning.
Why Choose Ideal Electrical for Your St Helens House Rewire?

CALL 07399 676656Does Rewiring Add Value When You Sell?
Yes, and most of the value is in what it stops a buyer knocking off. Whether you are selling, buying or renovating a St Helens property, here is why.
Old Wiring Costs You at Sale
Buyers of St Helens properties increasingly request an EICR before exchange. If your property fails, buyers use the result to renegotiate the price. Older St Helens properties frequently fail EICRs and give buyers leverage to reduce their offer by £3,000 to £8,000, often more than the rewire would have cost. A rewired home with a fresh NICEIC certificate removes that negotiation entirely. Citizens Advice outlines homeowner and landlord electrical obligations in full.
Request an EICR Before You Complete
If you are purchasing a St Helens property built before 1990, ask the seller to provide an EICR. If they cannot, factor the cost of a rewire into your offer. Plenty of St Helens houses have never had the wiring touched since they were built. The RICS home survey guidance recommends electrical inspection as part of any pre-purchase survey. We offer free surveys for buyers across all St Helens WA postcodes.

House Rewire St Helens: Your Questions Answered
Straight answers to what St Helens homeowners ask most about house rewiring.
FUNDINGCan you get a rewire paid for?
Almost never, if you own the house. There is no national grant for rewiring a property you own, whatever search results imply. If you rent from the council or a housing association it is your landlord's job and their cost under Section 11 of the Landlord and Tenant Act 1985. The other route is a Disabled Facilities Grant, administered by St Helens Council and worth up to £30,000 in England, where electrical work forms part of an adaptation. We do not offer finance and would rather say so than waste your time.
PAYMENTWhat are your payment terms for a rewire?
A 50% deposit secures your start date and covers the materials order. The remaining 50% is payable on completion, once your NICEIC Electrical Installation Certificate has been issued and handed to you. Nothing is payable between those two points, and the figure never changes from the written quote.
GUARANTEEWhat guarantee do you give on a house rewire?
A 10 year labour guarantee. If anything we installed is not right in that time, you ring us and we come back and fix it at our cost. On top of that, Hager and Prysmian warranty their own products, and the NICEIC Platinum Promise covers up to £25,000 for six years, though only in the event that we were no longer trading. We are also fully insured with £2 million public liability.
TIMELINEHow long does a house rewire take in St Helens?
A 2-bedroom St Helens property takes 2 to 3 days. A 3-bedroom house takes 3 to 4 days. A 4-bedroom house takes 4 to 5 days. That is roughly half the 5 to 10 days most national cost guides quote. Many clients stay in the property throughout, though your power is off for the whole job and there is no hot water until we finish. Read our full guide on how long a house rewire takes.
ASSESSMENTHow do I know if my St Helens property needs rewiring?
Any St Helens property should be assessed if any of these apply: an old fuse box with pull-out wire fuses, sockets on skirting boards, circuits that trip repeatedly, flickering lights, or a burning smell from any fitting. Read our guide on how to tell if your house needs rewiring. Book a free survey and we will assess your property honestly with no obligation to proceed.
COMPAREWhat is the difference between a full and partial rewire in St Helens?
A full rewire replaces everything: all wiring, sockets, switches, light fittings and the consumer unit throughout the entire property. A partial rewire replaces only the circuits that have failed or been condemned on an EICR. Partial rewires cost less upfront but may need completing later. We advise which is right at the free survey and will never recommend a full rewire if a partial would do the job.
DISRUPTIONHow messy is a St Helens house rewire?
There will be some disruption. Floorboards are selectively lifted, walls are chased for cable routes and there is no power during working hours. We use dust sheets throughout, hoover daily and clear all rubbish each evening. Day one is the worst of it and it gets better from there.
LIVINGCan I stay in my St Helens home during the rewire?
Yes. Most St Helens customers stay in their homes throughout. From day one none of your existing sockets, switches or lights work, and they stay dead until the new installation is tested. We fit one temporary socket at the meter so you can run an extension lead for a fridge, a kettle and a lamp. There is no heating or hot water while the job is on. Full mains power is restored on completion day.
INCLUDEDDoes a St Helens rewire include a new fuse box?
Yes, always. An 18th Edition consumer unit with RCD and surge protection is included in every rewire at no extra charge. The old fuse box is removed and replaced with a modern unit. All consumer unit replacements are notified under Part P of the Building Regulations. As NICEIC registered we handle this automatically at no extra cost or effort from you.
VALUEIs it worth rewiring before selling your St Helens home?
Almost always yes. Buyers increasingly request EICRs before completing a purchase and older St Helens properties frequently fail. A failed EICR gives buyers leverage to reduce their offer by more than the rewire would have cost you. Read more about when to rewire your home and house rewire costs.
Still got a question we have not answered? Ring and ask. No pressure and no obligation.
