Periodic Electrical Inspection Cost UK: 2026 Price Guide

Getting a quote for a periodic electrical inspection cost UK wide can feel like a guessing game. One engineer quotes £120, another wants £350 for what sounds like the same job, and you're left wondering who's overcharging or cutting corners. Property size, number of circuits, and whether it's domestic or commercial work all shift the price, so a single flat number never tells the full story.

This guide breaks down what you should actually expect to pay in 2026, based on real pricing patterns we see across London and the South East. You'll find typical costs for a one-bedroom flat right through to larger commercial units, plus what drives prices up, like old fuse boxes, extra outbuildings, or properties that haven't been inspected in over a decade.

We'll also cover how to compare quotes properly, so you're not just chasing the cheapest engineer but checking they're qualified, insured, and giving you a report that satisfies landlords, mortgage lenders, or insurers. By the end, you'll know what a fair price looks like for your specific property, not just a rough average pulled from nowhere.

Why the cost of a periodic electrical inspection varies so much

Ask five electricians for a quote on the same three-bedroom house and you'll likely get five different numbers. That's not necessarily dodgy pricing. An EICR price depends on how many circuits need testing, how accessible your wiring is, and how old your installation is. A flat, once rewired in 2015 with a modern consumer unit, takes far less time to inspect than a Victorian conversion with a mix of 1970s cabling and DIY additions from three different decades.

Property size and circuit count

Size matters, but not in the way most people assume. Engineers price EICRs by the number of circuits, not just square footage or bedroom count. A studio flat with an electric shower, cooker circuit, and separate lighting circuits can have nearly as many circuits as a modest three-bed semi. Bigger properties with annexes, outbuildings, or converted garages add extra circuits that need individual testing, which is why a five-bedroom house with a garden office can cost noticeably more than a similarly sized property without one.

Age and condition of the wiring

Older installations take longer to test safely. Rewireable fuses, rubber or lead-sheathed cabling, and undocumented alterations all slow an engineer down because they can't rely on accurate circuit charts. Older properties often need more isolation switching, more careful dead-testing, and more time spent tracing circuits that were never labelled properly. Newer builds with a recent consumer unit and clear circuit schedules go much faster, which is reflected in the quote.

A ten-minute difference in accessing your consumer unit can add hours to the job when it's multiplied across every circuit in the property.

Access and location

Where you live and how easy your property is to work in both affect price. Engineers travelling into central London face parking costs, congestion charge fees, and longer journey times than those covering outer boroughs or the wider South East, and that gets factored into the callout. Properties with sealed floor voids, boxed-in wiring, or limited loft access also take longer to inspect thoroughly, because the electrician has to work around obstructions rather than testing freely.

Domestic versus commercial classification

Quoting also depends on whether the job falls under domestic or commercial rules. Commercial EICRs generally follow a stricter inspection interval and often involve three-phase supplies, larger distribution boards, and emergency lighting circuits that need separate consideration. Government guidance on landlord electrical safety duties sets out minimum standards for rented domestic properties, but commercial premises are usually held to tighter inspection frequencies under general health and safety law, which pushes up both the scope and the cost of the report.

Here's a rough breakdown of what typically drives the price up or down:

Variation isn't a sign that someone's overcharging or underquoting blindly. It usually reflects genuine differences in how long the job will take and how much risk the engineer is taking on by signing their name to the report.

How electricians work out your EICR price

Most electricians don't pluck a number out of thin air. They work through a rough calculation that weighs time on site against risk, then add their standard hourly or day rate on top. Understanding this pricing logic helps you spot a fair quote versus one that's either inflated or suspiciously low.

Circuit-based pricing

Circuits are the main unit electricians use to scope a job, far more than bedroom count or floor area. A typical two-bed flat might have eight to ten circuits: lighting upstairs and downstairs, sockets, a cooker circuit, an immersion heater, maybe an electric shower. Each circuit needs dead testing, live testing, and visual inspection, so more circuits simply means more billable time. Some engineers quote a base price covering up to a set number of circuits, then charge a fixed amount per circuit beyond that.

Time on site versus report writing

Quoting isn't just about the hours spent testing. Writing up an EICR report properly, with observations coded correctly against BS 7671 and clear recommendations for any defects found, takes real time too. A rushed report that skips detail on remedial work isn't doing you any favours if you need to act on it later or show it to a landlord or mortgage lender. Electricians who build in proper report-writing time tend to charge a bit more, but you get a document that actually holds up to scrutiny.

Minimum callout charges

Most firms set a minimum charge regardless of property size, because even a small flat requires travel, setup, and report writing that takes a baseline amount of time. This is why a studio flat and a modest two-bed house sometimes land on similar prices, even though the second property has more circuits.

A quote that's noticeably cheaper than everyone else's usually means less time is being spent testing your circuits properly.

Here's roughly how the pricing components stack up:

Once you understand these components, a quote stops looking arbitrary and starts making sense against the actual work involved.

Typical EICR costs by property size and type

Numbers help more than theory, so here's what you should realistically expect to pay across different property types in London and the South East for 2026. These are typical ranges, not fixed quotes, because access, wiring age, and location still shift the final figure within each band. Treat them as a sense-check against whatever quote lands in your inbox.

Flats and small properties

Generally, studio flats and one-bedroom properties sit at the lower end of the market because they have fewer circuits to test. A one-bed flat with a modern consumer unit and straightforward access often comes in near the bottom of the range, while older conversions with boxed-in wiring or shared communal supplies push towards the top.

Family homes

Houses with three or more bedrooms typically carry more circuits, outbuildings, and sometimes an EV charger or electric shower on a dedicated circuit, all of which add testing time. Larger family homes with extensions or converted lofts often land at the higher end of the domestic scale.

A five-bedroom house with a garden office can cost more to inspect than a small block of flats, simply because of circuit count.

Commercial and larger properties

Commercial units, HMOs, and larger residential blocks move into a different pricing tier entirely, driven by distribution board complexity, three-phase supplies, and additional emergency lighting circuits that need separate testing.

Remember that these figures cover the inspection and report itself, not any remedial work flagged during testing. If your consumer unit needs replacing or a circuit fails insulation resistance testing, that's a separate cost on top. Comparing quotes against this table gives you a starting point, but always ask what's included before assuming a low number is the better deal.

What your EICR price actually includes

Paying for an EICR isn't just paying someone to flick switches and glance at your fuse board. A proper EICR price covers a structured inspection process defined by BS 7671, the UK standard for electrical installations, plus a written report you can actually use for insurance, mortgage applications, or landlord compliance. Knowing what should be bundled into that price helps you spot when a quote is missing something important.

The physical inspection and testing

Every competent EICR includes visual inspection of accessible wiring, consumer unit condition, earthing and bonding arrangements, and dead testing of circuits using calibrated equipment. Live testing follows, checking things like RCD trip times and loop impedance to confirm circuits will disconnect safely in a fault. Access to lofts, under-stairs cupboards, and outbuildings should be part of this, not treated as an optional extra that costs more once the engineer arrives.

The written report and coding

Once testing wraps up, the engineer codes any issues found using the standard C1, C2, C3, and FI system, then writes observations explaining what each code means for your property. This report is the actual deliverable landlords and mortgage lenders ask to see, so a rushed or vague version isn't worth much even if it was cheap.

The report is the product, not the visit itself, so a low price that skips detailed coding isn't actually good value.

What's typically included versus excluded

• Included: visual inspection, dead and live testing, earthing/bonding checks, coded written report, recommendations for remedial work

• Included: a schedule of test results showing readings for each circuit

• Excluded: actual remedial repairs to fix C1 or C2 defects

• Excluded: replacing a failed consumer unit or rewiring damaged circuits

• Excluded: re-testing after remedial work, which usually needs a follow-up visit

Always ask upfront whether the quote covers a full schedule of test results or just a summary page, since that difference matters if you ever need to challenge an insurer or satisfy a landlord's compliance check. Government guidance on landlord safety duties confirms that a proper EICR must include this level of detail to count as valid evidence of compliance, so a report light on specifics could leave you exposed later.

EICR costs for landlords versus homeowners

Who's paying for the inspection changes more than you'd think. Landlords face a legal deadline and a portfolio to manage, while homeowners are usually acting out of choice, so the pricing conversation looks different even when the property itself is identical.

Landlord obligations and pricing pressure

Since 2020, landlords in England must have a valid EICR for every rented property, renewed at least every five years or sooner if the previous report recommends it. That legal deadline changes how landlords shop for quotes. Missing the renewal date risks a fine and can invalidate insurance, so many landlords prioritise a reliable engineer over the absolute cheapest one. Landlords with several properties often negotiate a portfolio rate, where an electrician offers a slightly reduced per-property price in exchange for booking multiple inspections on the same day or across the same week. Official government guidance on landlord electrical safety duties sets out exactly what counts as compliant, and a report that falls short of those standards isn't worth the discount.

A landlord who chases the cheapest EICR and gets a non-compliant report ends up paying twice, once for the bad inspection and again for the proper one.

Homeowner discretion and peace of mind

Homeowners aren't bound by the same five-year rule, so the decision to book an inspection is usually driven by something specific: buying a property, arranging insurance, or simply wanting reassurance after years without a check. Because there's no deadline forcing the issue, some homeowners delay indefinitely, which isn't ideal given how much wiring can degrade unnoticed over a decade or more.

Here's how the two groups typically compare:

Both groups pay broadly the same base rate for the same property type, but landlords tend to weigh reliability and compliance more heavily, while homeowners often weigh cost against how urgently they need the report.

Extra costs to budget for beyond the inspection

Booking an EICR is rarely the last invoice you'll see. Most properties, especially anything over ten years old, throw up at least one defect that needs fixing, and that remedial work sits outside the original inspection price. Budgeting only for the periodic electrical inspection cost and ignoring likely follow-up work is how people end up caught out by a second bill they didn't plan for.

Remedial work for C1 and C2 defects

Coded observations aren't just notes on a page, they're a to-do list with real cost attached. A C1 defect means immediate danger and usually needs fixing before the electrician even leaves, while C2 defects are less urgent but still require action to keep the installation safe. Typical remedial jobs include replacing damaged sockets, correcting earthing faults, or upgrading circuits that fail insulation resistance testing. Costs vary widely depending on the fault, from a simple socket swap at under £50 to rewiring a full circuit for several hundred pounds.

A cheap EICR that flags a dozen defects isn't actually cheap once you add up the repair bill.

Consumer unit replacement

Older fuse boards, particularly anything with rewireable fuses or no RCD protection, almost always get coded as needing attention. Consumer unit replacement typically runs from £300 to £600 for a straightforward domestic swap, more if the existing wiring needs adapting to fit modern regulations. This is one of the most common follow-up costs landlords face, since older rental stock often still has outdated boards installed decades ago.

Retesting after repairs

Once remedial work is done, some landlords and homeowners assume the original report just gets updated. It doesn't work that way. A follow-up visit is usually needed to retest the repaired circuits and confirm they now pass, and that visit carries its own callout charge even if it's shorter than the original inspection.

A rough guide to what else to set aside:

• Minor remedial work (socket replacement, bonding corrections): £50 to £150

• Circuit-level repairs (rewiring a faulty circuit): £150 to £400

• Consumer unit upgrade: £300 to £600

• Retest visit after repairs: £60 to £120

Factoring these into your budget upfront, rather than treating the inspection as the final cost, saves you from an unpleasant surprise a week later.

How to choose a qualified electrician without overpaying

Price alone tells you almost nothing about whether an electrician is any good. Qualifications and registration matter far more, because an unqualified engineer might quote low, miss defects, and leave you with a report that no landlord, insurer, or mortgage lender will accept. Choosing well means checking credentials before you even look at the number on the quote.

Check registration and qualifications first

Genuine electricians should belong to a recognised competent person scheme, such as NICEIC or NAPIT, which confirms they're assessed against BS 7671 standards on a regular basis. Ask for their registration number and check it directly on the scheme's own website rather than trusting a logo on an invoice. The government's approved list of competent person scheme providers is a useful place to verify this yourself before booking anyone.

A qualified electrician with ten years of hands-on testing experience is worth more than a cheap quote from someone you can't verify.

Compare quotes on scope, not just price

Once you've confirmed someone's qualified, compare what's actually included in each quote rather than jumping straight to the cheapest figure. Ask these questions of every electrician you're considering:

• Does the price include a full schedule of test results, or just a summary?

• Is loft, outbuilding, and under-stairs access included, or charged separately?

• What happens if C1 or C2 defects are found, is a retest quote provided upfront?

• Are they insured, and can they provide proof of public liability cover?

• How many years of EICR-specific experience do they have, not just general electrical work?

Watch for red flags

Steer clear of quotes that arrive without a site visit or basic details about your property, since accurate pricing depends on circuit count and access, not guesswork. Also be wary of engineers who can't explain the coding system or seem unfamiliar with BS 7671 terminology when you ask a direct question. A properly qualified electrician should be happy to talk through their process, not just their price, and that conversation usually tells you more about value than the invoice ever will.

Budgeting for your next EICR

By now you should have a realistic sense of what a periodic electrical inspection cost looks like for your specific property, not just a vague average. Circuit count, wiring age, and access drive the price far more than bedroom count alone, and remedial work or a consumer unit swap can easily add to that initial figure. Treat the numbers in this guide as a sense-check, then compare quotes on scope and qualifications rather than chasing the lowest bid.

Whether you're a landlord facing a five-year deadline or a homeowner wanting peace of mind before selling, getting a qualified engineer who explains their pricing properly saves you money and hassle down the line. Don't wait for a tenancy renewal or a mortgage lender to force the issue.
