Most people don’t think about getting their electrics checked until something makes them — a house purchase, a renovation, or an insurer asking for proof the wiring is up to scratch. When they do start looking into it, the first question is always the same: how much does an electrical safety check cost?
The honest answer is less than most people expect, and more variable than most guides admit.
Electrical Safety Check Cost by Property Size
The more circuits in a property, the longer the inspection takes — that’s the most direct way to understand how pricing works. A studio flat might be done in under two hours. A large detached house with a garage, outbuilding, and multiple consumer units can take most of a day. This is why it is always best to get an expert local electrician who can do the job properly but in a timely manner.
| Property Type | Circuits (Approx.) | Typical UK Cost | Inspection Time |
|---|---|---|---|
| Studio / bedsit | 4–5 | £85–£135 | 1–1.5 hours |
| 1-bedroom flat | 5–7 | £100–£165 | 1.5–2 hours |
| 2-bedroom flat | 7–9 | £135–£200 | 2–2.5 hours |
| 2-bedroom terraced house | 7–9 | £145–£215 | 2–2.5 hours |
| 3-bedroom semi-detached | 9–12 | £175–£260 | 2.5–3.5 hours |
| 3-bedroom detached | 9–13 | £195–£280 | 3–4 hours |
| 4-bedroom house | 12–15 | £235–£330 | 3–4.5 hours |
| 5-bedroom house | 14–17 | £275–£385 | 4–5.5 hours |
| 6+ bedroom / large detached | 17+ | £300–£430 | 5–6+ hours |
| HMO (any size) | Varies | £310–£560+ | Half day+ |
| Small commercial unit | Per circuit | £30–£50 per circuit | Varies |
Electrical Safety Check Cost by UK Region
Where you live is one of the most significant pricing factors, and the gap between regions is bigger than most people realise. London and the South East routinely come in 25–35% above the national average. Move north or west and the picture changes considerably.
| Region | 3-Bed House Typical Range | Notes |
|---|---|---|
| London | £225–£375 | Highest labour rates in the UK |
| South East (Surrey, Brighton, Oxford) | £195–£315 | Follows London closely |
| South West (Bristol, Bath, Exeter) | £175–£275 | Broadly mid-range |
| East of England (Cambridge, Norwich) | £165–£255 | Slight premium in commuter areas |
| Midlands (Birmingham, Nottingham) | £155–£240 | Competitive and generally good value |
| North West (Manchester, Liverpool) | £150–£225 | Strong market, reasonable rates |
| Yorkshire and Humber | £145–£215 | Among the more affordable English regions |
| North East (Newcastle, Durham) | £135–£205 | Lower labour rates throughout |
| Scotland (Glasgow, Edinburgh) | £145–£230 | Broadly in line with Northern England |
| Wales (Cardiff, Swansea) | £135–£210 | Generally below the English average |
| Northern Ireland (Belfast) | £120–£195 | Lowest typical costs in the UK |
What Affects the Electrical Safety Check Cost?
Size and location account for most of it, but a few other things regularly push prices up — and it’s worth knowing about them before you get a quote.
Property age is the single biggest variable outside of size. Pre-1970s properties often have more individual circuits, older wiring types that take longer to test, and consumer units that require more thorough inspection. A sandstone tenement in Glasgow or a Victorian terrace in Manchester can take twice as long to inspect as an equivalent modern build — and the pricing reflects that.
Consumer unit type matters more than most homeowners expect. A modern board with RCDs and MCBs is quick to check. An older fuse board with rewirable fuses is slower to test and more likely to produce fault codes that require further investigation.
Accessibility is something contractors think about even if their clients don’t. Wiring hidden behind fitted units, in cluttered loft spaces, or under floorboards in multiple rooms adds time. So does anything that requires moving furniture or equipment before the inspection can begin.
Should You Be Suspicious of a Very Cheap Quote?
Yes — and it’s worth being straight about why. A thorough electrical safety check on a three-bedroom house takes a competent electrician between two and four hours to do properly. If a quote comes in at £80 for that job, the inspection is almost certainly being rushed.
A quick check that misses genuine faults isn’t a bargain — it’s a safety issue. The whole point of the inspection is to identify problems before they become dangerous. A substandard check can give a false sense of security that’s arguably worse than having no check done at all.
Always use a fully qualified, registered electrician. In Scotland, look for SELECT-registered contractors. Across England and Wales, NICEIC and NAPIT are the main approved bodies. These schemes have competency requirements and oversight that unregistered traders simply don’t.
If Your Electrical Safety Check Reveals Problems — What Then?
The inspection itself only covers the assessment. If the resulting Electrical Installation Condition Report — the EICR — comes back unsatisfactory, any remedial work is quoted and charged separately.
Fault codes matter here. C1 means immediate danger and requires urgent action. C2 is potentially dangerous and needs addressing before the installation is signed off. C3 is a recommendation rather than a requirement.
| Fault Type | Typical Remedial Cost |
|---|---|
| Faulty socket or switch | £50–£120 |
| Earthing or bonding issue | £100–£250 |
| RCD or MCB replacement | £80–£185 |
| Consumer unit replacement | £500–£1,100 |
| Partial rewire (one floor or area) | £1,500–£3,500 |
| Full house rewire | £2,500–£6,500+ |
For older properties where the wiring is deteriorated throughout — something we see regularly across Glasgow and the central belt of Scotland — a full house rewire costs more and tends to be the more cost-effective long-term answer compared to repeatedly addressing individual faults. At HomeRewire, we complete full house rewires in just 1–2 days rather than the 4–10 days most electricians take. That makes a real difference when remedial work needs to be signed off quickly and families are waiting to get back in.
How Long Does an Electrical Safety Check Certificate Last?
The standard interval is five years — a legal requirement for rental properties and the widely recommended timeframe for owner-occupied homes too. There’s no legal obligation for homeowners to hold a current certificate, but mortgage lenders and insurers increasingly ask for one, and not having a recent check can complicate a house sale at exactly the wrong moment.
If you’ve never had a check done since you moved in, or you’re about to take on a renovation and aren’t sure what’s behind the walls, getting it booked beforehand is always the smarter move.

Frequently Asked Questions
Is the electrical safety check price fixed or an estimate?
A reputable electrician should give you a fixed price upfront based on property size and type. Be cautious of anyone who can only offer an hourly rate before arriving — an open-ended inspection can cost considerably more than a fixed-fee quote.
Do I need an electrical safety check if I’ve just bought the house?
Not legally, unless you’re renting it out. But if the previous owner can’t provide a recent inspection report, getting one done before renovation work starts is a wise move — you’ll know exactly what state the wiring is in before a single wall gets touched.
Can I combine an electrical safety check with other electrical work?
Yes, and it’s often the most practical approach. If you’re having a consumer unit replaced or other electrical work carried out, ask the electrician to include the inspection at the same visit. Many will price it more favourably as part of a wider job.
What’s the difference between an electrical safety check and a PAT test?
An electrical safety check covers the fixed installation — wiring, consumer unit, sockets, light fittings. A PAT test covers portable appliances like kettles and lamps. For furnished rental properties both are advisable, but only the fixed installation check carries legal obligations for landlord electrical safety certificates.
How do I know if an electrician is qualified to carry out an electrical safety check?
Ask for their registration details before booking. In Scotland, SELECT is the main approved body. NICEIC and NAPIT cover England and Wales. Registration confirms competency standards have been met and that the electrician is subject to ongoing assessment.
Can HomeRewire carry out an electrical safety check in Glasgow?
Yes — we carry out electrical safety checks across Glasgow and central Scotland. If the inspection identifies faults or the property needs rewiring, we can handle that too, usually completing a full rewire within 1–2 days. Get in touch to book or get a quote.
