What Separates the Best Electrical Rewiring Services in Renfrewshire
Choosing the best electrical rewiring services in Renfrewshire comes down to three things: verified certification, a guarantee in writing, and insurance that actually covers domestic work. Everything else, from van livery to website polish, is noise. At Project Rewire, we can tell you plainly that the difference between a good contractor and a bad one rarely shows up on the quote.
Here is what most guides miss: a cheap rewire is almost never a bargain. It usually means fewer circuits, thinner cable, or a certificate signed off without the testing actually being done. The homeowner discovers this years later, often at sale, when a solicitor's search flags missing building regulations sign-off.
Certification, Guarantees and Insurance
Certification is the registration a competent person scheme issues to an electrician who has been assessed on the work itself, not just an exam. In the UK, NAPIT, NICEIC and ELECSA are the main scheme providers. Membership means the contractor can self-certify notifiable work, so you get the building regulations compliance document without a separate visit from the local authority (Building regulations approval: Use a competent person scheme).
Ask for three documents before anyone lifts a floorboard:
- Scheme registration number, which you can check on the provider's own register
- Public liability insurance certificate, current and in the business's legal name
- A written guarantee, with the term stated in years
Watch out: a verbal promise of "ten years" means nothing if the paperwork says twelve months. Get the guarantee term printed on the quote.
House Rewire Cost Scotland: What Drives the Price
The house rewire cost Scotland homeowners face is driven by four variables, not by postcode snobbery: property size, the number of circuits, access to walls and floors, and whether the consumer unit is being relocated. A three-bedroom semi with a modern layout costs materially less to rewire than a Victorian terrace with lath and plaster walls and no loft access.
Pricing depends on the scope of work, so treat any figure quoted over the phone as a placeholder. A proper survey takes an hour and produces a fixed price.
The biggest cost driver is disruption. Chasing cable routes into solid stone walls takes longer than dropping cable through a timber-framed partition, and labour is the bulk of the bill. Second is the consumer unit and earthing arrangement, particularly in older properties where the main earth may need upgrading to meet current requirements.
For a fuller breakdown of what affects the figure, read our guide on what drives house rewiring costs.
How Long Does a House Rewire Take?
A typical three-bedroom house rewire takes one to three weeks, depending on size, access and whether you are living in the property during the work. An empty property moves fastest. Occupied homes take longer because we work around you, sealing each room as we go.
The stages run in a fixed order:
- Survey and fixed quote
- First fix: cables, back boxes and containment
- Consumer unit and earthing
- Plastering and making good
- Second fix: sockets, switches and light fittings
- Testing, certification and handover
Most of the disruption happens in the first fix, and it is short. You will not be without power for weeks; we plan the schedule so the supply stays on except for the changeover day. If you want the full stage-by-stage detail, our team has written up the domestic rewiring process explained.
Electrician Qualifications for Rewiring: What to Check
Electrician qualifications for rewiring start with the Level 3 Award in the Requirements for Electrical Installations, usually called the 18th Edition, and a Level 3 technical qualification in electrical installation. Beyond that, a competent person scheme registration is the practical signal that matters, because it requires periodic assessment of real work.
What to check, in order:
- Scheme membership, verified on the provider's register
- 18th Edition certificate, current
- Public liability insurance
- Evidence of testing equipment and calibration
A common mistake is accepting a gas-safety registration as proof of electrical competence. It is not. They are separate schemes with separate assessments.

| Circuit detail | "Whole house" | Room-by-room schedule | Prevents shortcuts |
Full Rewire vs Partial Rewire: Which Does Your Property Need?
A full rewire replaces every cable, the consumer unit and all accessories. A partial rewire replaces a section, usually where a circuit has failed or an extension has been added. The honest test is the age and condition of the installation, not the inconvenience of the work.
Choose a full rewire when the wiring predates modern earthing and bonding, when the consumer unit has no residual current protection, or when multiple circuits show deterioration. Choose partial when the installation is recent and only one area is affected.
Where it falls short: a partial rewire on a 1960s installation often just moves the problem. If the cable insulation is brittle throughout, replacing one circuit leaves the rest waiting to fail. We would rather tell you that on the survey than after the invoice.

Frequently Asked Questions
How do I choose reliable electrical rewiring services for an older property?
Check three things before you book. First, confirm the contractor is NAPIT-approved or registered with a comparable competent person scheme, and ask for the registration number so you can verify it. Second, ask what guarantee comes with the work; a 10-year guarantee on a full rewire is a strong signal of confidence. Third, request a written quote that itemises cabling, consumer unit, accessories, making good and certification. A contractor who cannot explain what happens after the rewire, including the EIC certificate and building regulations notification, is worth avoiding.
How much does a house rewire cost in Scotland?
Pricing depends on the size of the property, how many circuits you need, whether the walls are solid stone or modern cavity, and how much making good is required afterwards. A 1960s semi with original wiring will cost more than a flat with easy cable routes. Because every quote is property-specific, ask for a written breakdown rather than a single figure, and confirm whether VAT, certification and making good are included. Request a quote based on a site visit, not a phone estimate.
Do I need to move out during a house rewire?
Most homeowners stay put, but expect disruption. Power will be off for parts of each day, and floors and walls will be opened up for cable routes. Plan for the kitchen and any home-working setup to be affected for the noisiest days. Ask your electrician to sequence the work so at least one usable circuit stays live where possible, and agree in advance which rooms are tackled first. If you have young children or vulnerable residents, discuss a phased schedule before work starts.
What certificates should I receive after a house rewire?
You should receive an Electrical Installation Certificate (EIC) for the new installation, plus notification through a competent person scheme so the work is recorded as compliant with Building Regulations. If the rewire includes a consumer unit change, the certificate must cover that too. Keep the EIC with your property documents; buyers and solicitors will ask for it during a sale, and landlords need it to support EICR compliance. Ask for the certificate before final payment, not weeks later.
Most homeowners put off a rewire until a surveyor, a solicitor or a flickering light forces the issue. You do not have to wait for that. Project Rewire offers NAPIT-approved certification, a ten-year guarantee on every rewiring job, and a team that specialises in domestic rewires across Renfrewshire, Glasgow and Ayrshire. Get started with Project Rewire and book a survey that gives you a fixed price and a clear plan.
