Cost of Rewiring a House in Scotland: What Changes the Price
A Scottish rewire typically costs {range:house-rewiring:mid}. See how stone walls, period homes, a new consumer unit and certification move your quote.
Rewiring a 100 m² house typically costs £6,800, with most quotes falling between £5,300 – £8,850. Basic jobs start around £5,500 and premium jobs reach £8,900, all including VAT. In Scotland, the wall construction usually matters more than the postcode.
Our general guide to House rewire covers the basics. This article covers the questions Scottish buyers and owners ask most: what stone and tenement walls do to the price, and what to check on certification.
Why Scottish rewires can cost more
Much of Scotland's housing is built differently from the typical English brick-and-plasterboard home. Solid stone houses, tenement flats and older villas are common. Each makes cable routing harder.
- Solid stone or thick masonry walls. Cables can't run through a cavity or a stud wall. Electricians have to chase channels into hard walls or find another route, which takes longer.
- Lath-and-plaster and old lime plaster. These are fragile. Chasing them risks damage, so the work goes slower and more repair is needed.
- Tenement flats. Access to shared floor voids, stairwells and meter positions can be awkward. Working around neighbours and shared parts of the building adds time.
- Older properties generally. Surprises such as old wiring, hidden junctions and awkward floor construction tend to turn up once boards are lifted.
Standard or period property: the price gap
The biggest single option in our model is the wall type. Here is the typical mid-range cost for each, for the same 100 m² house:
| Construction | Typical cost |
|---|---|
| Standard construction | £6,800 |
| Period or listed house (pre-1900) | £8,550 |
| Material | Typical | Usual range | Lifespan |
|---|---|---|---|
| Standard construction | £6,800 | £5,300 – £8,850 | – |
| Period or listed house (pre-1900) | £8,550 | £6,650 – £11,100 | – |
If your home is a Victorian villa, a stone cottage or a listed building, use the period figure as your starting point. A 1960s bungalow or a newer build will sit closer to the standard one.
We calculate these figures from labour hours multiplied by local rates, plus materials. We then check them against market prices and real quotes. Period homes cost more mainly because of the extra labour hours.
The consumer unit decision
A modern consumer unit with RCBOs and surge protection is often the sensible choice in a rewire. Compare the two board options:
- Keep the existing board. This is only reasonable if it is modern and passes testing. It is the cheaper route, but you should not assume an old fuse box will survive.
- New consumer unit. Typical mid-range rewire cost with a new board is £6,800, against £6,150 if you keep the board.
GOV.UK says that repairs and replacements generally need no building regulations approval, except heating systems, oil tanks, fuse boxes and glazing units. So a new consumer unit is treated differently from routine repairs and is notifiable work.
Hidden costs to ask about
Many Scottish quotes differ because of what they leave out. Check each of these:
- Making good. After chasing stone or plaster, is the quote "chases and holes filled, ready for decorating" (£6,800) or does it include replastering and redecorating (£8,300)?
- Living in the house. Working around furniture and a family takes longer. An empty house costs £5,700 against £6,800 when you are living there.
- Floors and access. Are floorboards, carpets and flooring lifted and relaid by the electrician? Who pays if something breaks?
- Testing and certificates. See below.
If you plan to refloor or redecorate afterwards, schedule the rewire first. Our guides on New flooring and Painting and decorating show what those follow-on jobs cost.
Certification in Scotland
Our fact sheet covers the position in England and Wales: notifiable electrical work must be done by a registered electrician (Part P) or notified to building control. Scotland has its own building standards system, so do not assume the English route applies to you. We don't give detailed Scottish rules here. Instead, before you sign:
- Ask the electrician which registration or competent-person scheme they work under in Scotland.
- Ask what certificate you will receive when the work is finished, and make sure it is listed in the quote.
- Check with your local council's building standards team whether your job needs a warrant or notification.
- Keep the paperwork. It matters when you sell, and your insurer may ask for it.
An uncertified rewire can cause problems later. Never pay for certification as an optional extra.
Check your quote
Before accepting an estimate, run it through our "is my quote fair" tool. Compare it against these points:
- Does the quote say what wall type it assumes?
- Is the consumer unit included, and is it RCBO-based?
- Are making good and redecoration included or excluded?
- Is testing and certification named?
- Does the price assume an empty house or one you are living in?
A quote far below the range may leave out making good or the consumer unit. One far above it may assume a period property when yours is standard.
If your rewire is part of a bigger project, see our guides to Bathroom renovation and New kitchen. Rewiring first often saves a lot of rework.
The bottom line
For a typical 100 m² home, plan on £6,800. If it's a stone-built or pre-1900 property, expect something closer to £8,550. Get at least three itemised quotes and ask each electrician about Scottish certification before you commit.
