EICR Cost London: 2026 Prices By Property Size & Circuits

If you're searching for EICR cost London prices, you've probably noticed that quotes vary quite a bit depending on who you ask. A one-bedroom flat and a five-bedroom house are completely different jobs, yet many websites lump them together under a single "from" price, which isn't particularly helpful when you're trying to budget for a specific property.

The truth is, several factors determine what you'll pay: the number of circuits, the size and type of the property, the age of the wiring, and whether you need a domestic or commercial inspection. Understanding these variables puts you in a much stronger position to compare quotes fairly and avoid overpaying. It also helps you spot prices that seem suspiciously low, which can sometimes mean corners are being cut.

At Electrical Testing London, we carry out EICRs across London and the South East every day, for landlords, homeowners, and commercial clients. Our engineers each have at least 10 years of experience, and we believe in straightforward pricing with no hidden extras. We've put this guide together based on what we see in the current London market as of 2026, drawing directly from our own pricing and industry knowledge.

Below, you'll find a full breakdown of EICR costs by property size and circuit count, along with the key factors that push prices up or down. Whether you're a landlord preparing for a compliance deadline or a homeowner who wants peace of mind, this guide will give you the clear figures you need before booking an inspection.

Why EICR pricing in London looks different

If you've compared EICR cost London quotes side by side, you'll have noticed that prices don't follow a simple formula. A quote from a sole trader in an outer borough can look very different from a quote by a certified firm operating in Zone 1, and both might be for the same type of property. That gap isn't always a red flag, though low prices sometimes are. More often, it reflects a set of genuine cost variables that experienced electricians factor in when they price a job in the capital.

London-based electrical firms carry higher overheads than those operating in most other parts of the UK, and that reality shows up directly in their pricing.

London's operating costs are genuinely higher

Running an electrical business in London costs significantly more than running one almost anywhere else in the country. Fuel, parking charges, and congestion fees all eat into an engineer's time before they even reach your property. Add in the higher cost of public liability insurance and business rates in the capital, and you can see why a well-run London firm charges more than a national comparison site's headline rate might suggest.

These costs are not padding. They reflect the real expense of delivering a reliable service in a city where van parking alone can cost more than a full hour's labour in other regions. When you're looking at quotes, a price that accounts for these realities is usually a sign that the company is operating professionally.

Property age and wiring condition

London has a large stock of Victorian and Edwardian housing, and older properties take longer to inspect. Fuse boards wired before the 1960s often use outdated materials like rubber-insulated cables, which require closer scrutiny and more detailed reporting. An engineer working through a mid-century property with non-standard circuits will take considerably longer than one inspecting a new build with a modern consumer unit and clean cable runs.

Your property's age is not unique to London as a challenge, but it is far more common here given the housing stock. If your property was built before 1970, expect that factor to influence your quote.

Domestic versus commercial properties

Residential and commercial EICRs follow different testing criteria and require different levels of documentation. A commercial inspection covers more circuits, more complex distribution boards, and often involves three-phase supplies, emergency lighting circuits, and higher-load equipment. That additional scope takes more time and specialist knowledge, which is reflected in the price.

For residential landlords, the rules are set out under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, which require a valid EICR at least every five years. Commercial premises operate under separate health and safety legislation, and testing intervals can vary based on the type of business and environment. Knowing which category applies to your property before you request a quote will save time on both sides.

Number of circuits: the single biggest cost driver

The number of circuits in your consumer unit is the most reliable predictor of what your EICR will cost, regardless of property type. Each circuit needs to be tested and recorded individually, so a flat with six circuits takes less time than a house with fourteen. Most electricians price by circuit count or use property size as a proxy, since bedroom count broadly correlates with circuit numbers in standard residential builds.

EICR cost London 2026 at a glance

The figures below are based on current London market rates as of 2026, drawn from our own pricing and what we observe across the industry. These prices cover a standard single-phase domestic inspection carried out by a qualified engineer within Greater London. They do not include any remedial work identified during the inspection, which we cover separately later in this guide.

Typical price ranges for residential properties

For most residential properties, EICR cost London falls within a fairly predictable band once you factor in the size of the property and the number of circuits. The table below gives you a solid reference point for the most common property sizes across the capital.

These ranges reflect standard wiring in reasonable condition with a single consumer unit. Properties with older wiring, split consumer units, or additional circuits for outbuildings or EV chargers will typically sit toward the higher end or above these figures.

Always treat "from" prices advertised online with caution. The headline rate rarely applies to anything beyond the simplest possible property.

What affects where your quote sits in that range

Two key variables pull your quote toward the top or bottom of these bands: the condition of your existing wiring and the complexity of your consumer unit setup. A property with a modern consumer unit, clear circuit labelling, and accessible cable runs will be faster to test and therefore cheaper to inspect.

Older properties or those with previous unauthorised electrical work take longer because the engineer needs more time to trace circuits, identify non-standard installations, and document findings accurately. If you're in any doubt about your property's electrical history or the number of circuits installed, mention it upfront when you request a quote. That way, the figure you receive reflects the actual scope of the job rather than a best-case assumption.

Prices by property size in London

Property size gives you the most practical starting point when estimating your EICR cost London, because it directly predicts how many circuits your engineer needs to test. While the circuit count is the technical driver, most people think in terms of bedrooms and property type, so breaking down prices this way makes it easier to set a realistic budget before you call anyone.

Flats and smaller properties

Studio and one-bedroom flats typically involve five to seven circuits, covering lighting, sockets, a cooker or hob outlet, and a shower or immersion heater. For a standard flat in good condition, you can expect to pay between £150 and £220 for a domestic EICR in London. Leasehold flats in older mansion blocks sometimes have shared wiring that complicates the inspection, which can push the price higher.

Two-bedroom flats and small terraced houses sit in the £200 to £280 range for most London properties. These properties often have an additional ring circuit and sometimes a dedicated circuit for a washing machine or dishwasher. If the flat was converted from a larger house, the wiring layout may be less straightforward, so it's worth mentioning this when you request your quote.

Converted properties almost always take longer to inspect than purpose-built ones of the same size, so treat that as a budget consideration from the start.

Mid-sized family homes

Three-bedroom houses represent the most common job type for residential EICRs in London. Circuit counts typically fall between ten and twelve, covering multiple lighting zones, upstairs and downstairs ring circuits, a dedicated kitchen circuit, and outdoor or garage supplies where fitted. Prices for this property size generally run from £250 to £350 in the current London market.

Four-bedroom houses add at least two or three more circuits on average, and the inspection time rises accordingly. Expect to budget between £300 and £420 for this size. Properties with extensions or conservatories may have additional sub-circuits that need to be included in the scope.

Larger houses and HMOs

Five-bedroom houses and above usually involve fifteen or more circuits, and some larger properties have secondary consumer units serving extensions, outbuildings, or garden offices. These add time and are priced accordingly, typically £380 to £500 or above depending on complexity.

Houses in multiple occupation (HMOs) carry specific compliance requirements under licensing conditions, and the inspection scope is broader than a standard residential EICR. If your property is licensed as an HMO, request a quote that specifically reflects that status rather than defaulting to a standard domestic price.

Prices by circuits and consumer unit setup

Circuit count is the figure that electricians actually use when they price a job, even when they quote you a price based on bedroom count. Knowing how circuits map to costs helps you understand why two properties of identical size can produce different quotes, and it puts you in a better position to question or confirm any figure you receive for your eicr cost London inspection.

How circuit count translates to inspection time

Each circuit in your consumer unit requires individual testing and documentation, which is why the number of circuits is the most direct driver of inspection time and therefore cost. A typical one-bedroom flat might have six circuits: two lighting circuits, two ring final circuits for sockets, a cooker outlet, and a shower circuit. A three-bedroom house with a garage and garden lighting could have fourteen or more, and each additional circuit adds time to the job.

The difference between a six-circuit flat and a fourteen-circuit house can easily add an hour or more to an inspection, which is why circuit count matters more than square footage.

The table below shows how circuit count typically affects pricing for a standard single-phase domestic inspection in London.

Split consumer units and sub-boards

Some properties, particularly those that have been extended or rewired in stages, have more than one consumer unit. A main board in the hallway and a secondary board in a garage or rear extension each need to be inspected separately. This adds both time and cost, so always mention split boards when you request a quote.

Properties with a mix of older and newer wiring connected across multiple boards take longer to test because the engineer needs to trace circuits carefully before testing can begin. If your property has had unauthorised electrical work at any point, that complexity increases further and your quote should reflect it.

What to tell your electrician before they quote

Giving your electrician accurate information upfront leads to a more reliable quote and fewer surprises on the day. Tell them how many consumer units the property has, whether any circuits serve outbuildings or garden structures, and whether you know of any recent electrical work that may not have been signed off. These details take seconds to share and can prevent a quote from being revised once the engineer arrives on site.

What the EICR price usually includes

When you receive a quote for eicr cost london, it's worth knowing exactly what that figure covers before you confirm the booking. Most reputable electricians include the same core components in their price, but a small number of firms strip out elements to advertise a lower headline rate, then charge separately for things you'd reasonably expect to be included.

Confirming what's in the price before you book saves you from unwelcome additions to your invoice after the work is done.

The full on-site inspection

Your quote should always cover the complete on-site inspection carried out by a qualified engineer. This means testing every circuit in your consumer unit individually, checking the condition of the board itself, verifying that all protective devices function correctly, and visually inspecting accessible wiring throughout the property. The engineer will also check earthing and bonding arrangements, socket outlets, light fittings, and any fixed equipment connected to a dedicated circuit.

The inspection follows the procedures set out in BS 7671, the UK wiring regulations, which defines the standard your electrician must work to. A thorough inspection at a standard three-bedroom house typically takes two to four hours, depending on circuit count and the condition of the installation.

The written report and certificate

Once the inspection is complete, your electrician produces the written report, which is the formal document you actually need for compliance purposes. This documents every observation, test result, and code assigned to each item found during the inspection. Codes run from C1 (danger present, requiring immediate action) through to C3 (improvement recommended) and FI (further investigation needed).

Your report should include a schedule of circuit details, test results for each circuit, and a clear statement of whether the installation is satisfactory or unsatisfactory. You receive this as a signed and dated certificate, and most firms now issue it digitally within 24 to 48 hours of the visit.

Call-out and travel within your area

Reputable London firms include local travel and call-out within their quoted price for properties falling within their service area. Confirm this when you book. Some companies add a separate call-out fee that only appears at the invoice stage, which is not standard practice and should prompt you to ask for clarification upfront.

Extra costs after the report: remedial work

Your EICR cost London quote covers the inspection and the report itself, but it does not include any work needed to fix problems the engineer identifies. If your installation receives an unsatisfactory outcome, you'll need to address the coded items before the property is legally compliant. Understanding what remedial work typically costs helps you set a realistic total budget rather than treating the inspection fee as the only figure that matters.

When remedial work becomes necessary

An EICR assigns a code to every issue found during the inspection. C1 codes indicate immediate danger and require action before the property can be used safely. C2 codes flag potentially dangerous conditions that need addressing within a defined timeframe, while C3 codes are recommendations rather than requirements. If your report includes any C1 or C2 observations, you must have those items repaired and produce a minor works certificate or a new report to confirm the installation is now satisfactory.

A C1 or C2 finding does not mean your property has failed permanently. It means specific items need fixing, after which a follow-up check confirms compliance.

Older London properties are more likely to produce codes related to inadequate earthing or bonding, deteriorated cable insulation, or consumer units that no longer meet current standards. These are common findings and, in most cases, straightforward for a qualified electrician to address.

What remedial work typically costs

Costs vary depending on what the engineer finds, but the most common repairs fall into a predictable range. Minor bonding or earthing corrections typically cost between £80 and £200. Replacing a single faulty socket, damaged switch, or defective circuit protective device usually falls between £50 and £150 per item. A full consumer unit replacement, which is one of the more significant remedial outcomes, generally costs between £400 and £700 for a standard domestic property in London.

Your electrician should provide a written quote for all remedial work before any repairs begin. Reputable firms separate the inspection fee from remedial costs clearly, so you always know what you're paying for at each stage.

How to manage remedial costs sensibly

Booking your remedial work with the same firm that carried out your inspection often saves time because the engineer already knows your installation and can work more efficiently. Some firms offer a combined rate if remedial work is booked at the same time as the EICR, which is worth asking about when you request your initial quote.

If your property is older or has a history of piecemeal electrical work, it helps to set aside a contingency budget of 20 to 30 percent above the inspection fee to cover the most common remedial findings. That approach removes most of the financial uncertainty from the process.

How to get an accurate quote and avoid surprises

Getting a reliable eicr cost london quote comes down to one thing: giving your electrician accurate information before they name a price. A quote built on assumptions is almost always revised upward once the engineer arrives, which creates frustration and sometimes delays compliance deadlines. The best way to avoid that outcome is to treat your initial enquiry as a brief information exchange, not just a request for a number.

Give the right information from the start

Your electrician needs specific details to price your job accurately. Vague requests produce vague quotes, and vague quotes rarely survive contact with the actual property. Before you call or submit an enquiry form, gather the following:

• Number of bedrooms and property type (flat, terraced house, detached house, HMO)
• Whether you have one or more consumer units, including any secondary boards in garages or extensions
• The approximate age of the property and whether you know of any rewiring work done since it was built
• Any circuits serving outbuildings, garden offices, or EV chargers
• Whether the property is tenanted or vacant on the day of inspection

Sharing these details upfront takes less than two minutes and gives the electrician everything they need to quote accurately for the actual scope of the work.

Red flags in low-cost quotes

Not all low prices reflect genuine value. Quotes significantly below the typical London market range sometimes exclude the written report, assume a circuit count that does not match your property, or carry hidden call-out charges that only appear on the final invoice. If a price looks unusually low, ask the firm to confirm exactly what is included.

A quote that does not specify circuit count or property type is not a fixed price. It is an estimate with room to grow.

You should also check that the electrician is registered with a competent person scheme such as NICEIC or NAPIT before booking. This confirms they are qualified to carry out and certify the inspection to BS 7671 standards. Asking for this upfront protects you from paying for a report that carries no regulatory validity, which would require you to pay for a second inspection from a qualified firm anyway.

Your next step

By now, you have a clear picture of what eicr cost london looks like in 2026, from a studio flat through to a large HMO. You know which factors push prices up, what your report should include, and how to share the right information so your quote reflects the actual job rather than a best-case assumption.

The most useful thing you can do next is get a fixed quote based on your specific property. That means telling the electrician your property type, the number of consumer units, any circuits serving outbuildings, and the approximate age of the wiring. Those details take moments to pull together and remove almost all the uncertainty from the process.
