Electrical Installation Report Cost: UK Prices, By Property

An electrical installation report cost can range anywhere from £100 to well over £1,000, depending on the size and type of property being tested. That's a wide spread, and if you've been quoted a figure that feels too high (or suspiciously low), you're right to want a clearer picture of what drives the price.

The report itself, formally called an Electrical Installation Condition Report (EICR), is a legal requirement for landlords in England and a strongly recommended safety check for homeowners and commercial property operators alike. Yet pricing remains one of the most common questions we hear at Electrical Testing London, where our engineers carry out EICRs across London and the South East every day.

In this article, we break down current UK prices for EICRs by property size, number of circuits, and building type. We'll explain what's actually included in the cost, what can push it higher, and where some providers cut corners to offer cheaper quotes. By the end, you'll have enough detail to compare quotes confidently and understand exactly what you're paying for.

Why an electrical installation report matters

An Electrical Installation Condition Report (EICR) is a formal document that tells you whether the fixed wiring in a property is safe and up to standard. An electrician carries out a series of visual checks and electrical tests, then grades the findings using a code system. Code C1 means immediate danger, Code C2 means a potentially dangerous fault, and Code C3 means improvement recommended. The report concludes with either a "Satisfactory" or "Unsatisfactory" result, and that outcome carries real consequences for landlords, business owners, and homeowners alike.

Legal requirements for landlords

If you rent out a residential property in England, you have a legal obligation under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 to have a valid EICR in place. You must carry out the inspection before a new tenancy begins and at least every five years after that. You're also required to provide a copy of the report to your tenants within 28 days of the inspection and to your local authority if they request it.

Failure to comply with these regulations can result in a fine of up to £30,000 issued by your local authority.

Landlords who manage multiple properties need to track EICR expiry dates across their portfolio. Missing a renewal date doesn't just create a legal risk; it can also invalidate your landlord insurance if an incident occurs and an out-of-date report comes to light. Keeping on top of your electrical installation report cost as a routine budget line, rather than an unexpected expense, is the smarter approach.

Safety risks of skipping an EICR

Faulty electrical installations are one of the leading causes of house fires in the UK. The wiring in older properties, particularly those built before 1970, may not meet current standards set out in BS 7671 (the IET Wiring Regulations). Problems like deteriorating cable insulation, overloaded circuits, or absent residual current devices (RCDs) can sit undetected for years until they cause a fire or an electric shock.

An EICR gives you documented evidence of the condition of your installation at a specific point in time. If your property has never been tested, or if the last report is more than five years old, you have no reliable way to know whether the wiring is safe. Electrical faults don't announce themselves before they become serious, and the consequences of missing one far outweigh the cost of the inspection.

When homeowners and commercial clients need one too

Homeowners are not legally required to hold an EICR, but there are several situations where getting one is strongly advisable. If you're buying a property, an EICR gives you a clear picture of the electrical condition before you complete the purchase. It can be used as a negotiating tool if faults are found, and it protects you from inheriting someone else's problem wiring.

For commercial property owners and businesses, the obligation comes from health and safety legislation. The Health and Safety at Work etc. Act 1974 and the Electricity at Work Regulations 1989 both place a duty on employers to maintain safe electrical systems. Insurers also increasingly require a valid EICR as a condition of commercial property cover. The testing frequency for commercial premises depends on the type of business and the environment: a factory or kitchen carries higher risk than an office, so inspections are recommended more often. Regardless of the setting, an up-to-date report is your proof that you've taken your duty of care seriously.

Average EICR costs in the UK for 2026

Understanding the typical electrical installation report cost before you book gives you a realistic benchmark to compare against the quotes you receive. In the UK for 2026, domestic EICR prices generally start at around £100 for a small flat and climb past £400 for a larger house. Commercial properties sit in a broader range, from roughly £150 for a compact office up to £1,500 or more for a large industrial unit. The figures below reflect standard market rates for a qualified electrician working to current regulatory requirements.

These figures assume straightforward access and a standard installation. Properties with unusual layouts, outdated wiring systems, or poor access to cable routes can push costs higher.

Domestic EICR prices

For residential properties, price scales directly with the number of circuits in the consumer unit and the overall size of the property. More circuits mean more tests, more time on site, and a higher overall fee. The table below gives a clear picture of what you should expect to pay across different domestic property sizes.

Quotes below the lower end of these ranges are worth scrutinising. A cut-price EICR can mean fewer tests carried out, less thorough documentation, or an engineer who is not fully qualified to sign off a report under the BS 7671 standard.

Commercial EICR prices

Commercial pricing works on the same principle, but the scale and complexity are typically much greater. A small office or retail unit with a single consumer unit might cost between £150 and £300, while a mid-size commercial premises with multiple distribution boards could reach £600 or more. Large industrial, manufacturing, or multi-floor buildings often require a bespoke quote because the circuit count, testing time, and access requirements vary considerably from one site to the next.

For businesses, the inspection frequency also affects your overall spend. Higher-risk environments such as kitchens, workshops, or facilities with public access require more frequent testing than a standard office, so factor that into your budget when you plan ahead.

EICR price by property type and size

Property type shapes your electrical installation report cost just as much as the number of bedrooms. A two-bed flat in a modern conversion and a two-bed house built in the 1960s might look similar on a listing, but they can produce very different inspection fees. The key variables are circuit count, wiring age, and how the property is occupied, all of which shift the time an engineer needs to complete the job properly.

Single-occupancy domestic properties

For a standard owner-occupied or single-let house or flat, pricing follows a straightforward pattern. Smaller properties with fewer circuits cost less because the inspection and testing time is shorter. A one-bedroom flat typically falls between £100 and £130, while a five-bedroom house can push past £400 once you account for the additional circuits serving lighting, sockets, cooker, and outdoor supplies.

Always confirm with your electrician exactly how many circuits they're pricing for. If the actual count is higher on the day, costs can increase.

Older properties require more care during testing because deteriorating insulation or outdated wiring systems like rubber-sheathed cables may require slower, more methodical checks to avoid causing damage during the assessment. That additional time is reflected in the final price.

HMOs and multi-unit buildings

Houses in multiple occupation present a more complex picture. Each self-contained unit within an HMO typically has its own circuits, and there are usually shared circuits covering communal lighting, hallways, and fire alarm systems. An engineer may need to inspect each unit separately and test the communal installation alongside it, which significantly increases the time on site.

HMO landlords should expect to pay more per property than for an equivalent single-let, often in the range of £300 to £600 or higher depending on the number of units and letting rooms. Blocks of flats operate on a similar basis: each flat may carry its own EICR requirement, while the communal areas need a separate report covering the shared installation.

Commercial and industrial premises

Commercial pricing depends on the scale and nature of the business premises. A small retail unit or single-office space with one consumer unit sits at the lower end, typically £150 to £300. Larger premises with multiple distribution boards, three-phase supplies, or specialist equipment circuits require considerably more time and cost proportionally more. Industrial units and warehouses routinely attract bespoke quotes because no two sites carry the same layout or circuit complexity.

What drives the cost of an EICR

Several factors determine your electrical installation report cost, and understanding them helps you see why two properties of a similar size can produce quotes that differ by a hundred pounds or more. The price isn't arbitrary; it reflects the actual time and complexity involved in completing a thorough, compliant inspection.

Number of circuits

The single biggest factor in EICR pricing is the number of circuits in your consumer unit. Each circuit requires individual testing, including insulation resistance checks and continuity measurements, and each result must be recorded in the report. More circuits mean more time on site, which directly raises the engineer's fee. A one-bedroom flat with six circuits is a fundamentally different job to a four-bedroom house with fourteen, even if the properties are geographically close to each other.

Always ask your electrician to confirm how many circuits they are pricing for before you book, so you aren't caught out by a higher count on the day.

Age and condition of the wiring

Older wiring systems take longer to test safely. Properties built before the 1970s often contain rubber-sheathed or aluminium wiring, which is more fragile and requires a slower, more careful approach during insulation resistance testing. If the wiring is visibly deteriorated or the installation hasn't been inspected for many years, the engineer may need to spend additional time tracing cable routes and documenting the condition in detail. Properties with outdated consumer units, such as older fuse boards with rewirable fuses, also add time because the engineer needs to assess whether the existing protection meets current BS 7671 requirements.

Access and site conditions

The physical layout of your property affects how quickly an engineer can work through the inspection. Concealed cabling, restricted roof spaces, or limited access to distribution boards all slow the job down. On a commercial site, the issue is often scale: a multi-floor building where distribution boards are located in locked plant rooms or across different zones requires more travel time between test points, and that time forms part of the overall cost.

London and South East pricing can also sit slightly higher than national averages due to travel costs, parking charges, and the general cost of operating in the capital. Factoring in these variables gives you a clearer picture of what a fair quote actually looks like for your specific property.

What the inspection includes and how long it takes

When you pay for an EICR, you're paying for two distinct phases of work: a visual inspection and a series of electrical tests. Both phases must be completed for a report to meet the requirements of BS 7671, and the depth of each phase directly shapes your overall electrical installation report cost. Understanding what's involved helps you verify that any engineer you hire is actually delivering a compliant service.

What the engineer tests during the visit

The visual inspection covers the condition and safety of all accessible electrical components, including the consumer unit, wiring, sockets, switches, light fittings, and any visible cable runs. Your engineer looks for signs of damage, overheating, improper connections, or non-compliant work carried out since the last inspection. Anything that poses a risk or falls below the standard required by BS 7671 gets recorded with the appropriate code.

Each circuit then undergoes a set of electrical measurements using calibrated test equipment. Your engineer carries out insulation resistance tests to check for deterioration in cable insulation, continuity tests to verify that protective conductors are intact, and polarity checks to confirm correct wiring throughout. They also test RCD (residual current device) operation to confirm that your shock protection devices trip within the required time. Every result is recorded on a schedule of circuit details, which forms the technical backbone of your final report.

A completed EICR should include a full schedule of test results alongside the observations and any coded defects. A report delivered without these is not compliant with BS 7671.

How long the inspection takes

Time on site depends primarily on property size and the number of circuits being tested. A one-bedroom flat with six circuits typically takes two to three hours, while a large house with fourteen or more circuits can require a full day. Commercial premises with multiple distribution boards can require more than one engineer or return visits, particularly where live circuits cannot be safely de-energised during business hours.

The table below gives a practical guide to expected durations across common property types.

Costs after the report: repairs, retests, upgrades

The electrical installation report cost doesn't always end when the engineer hands over the completed document. If your report comes back "Unsatisfactory" with one or more Code C1 or C2 findings, you're required to carry out remedial work before the installation can be signed off as safe. How much that work costs depends entirely on what the report identified, so it's worth understanding the most common scenarios before you book your inspection.

Remedial electrical work

Code C1 faults require immediate action because they indicate a present danger to anyone using the property. Code C2 faults must be addressed within a defined period, and for landlords in England that period is typically 28 days from the date of the report. Minor remedial jobs, such as replacing a damaged socket, fitting an RCD, or correcting a faulty connection, generally cost between £50 and £200 per item depending on the complexity of the fix.

If your property receives multiple coded observations, the combined remedial cost can quickly exceed what you paid for the inspection itself.

Where the issues are more widespread, for example deteriorating insulation across several circuits or absent earthing on a number of accessories, the work required is more substantial. Your electrician should provide a clear itemised quote for the remedial work before any fixes begin, so you know exactly what you're committing to.

Consumer unit replacement

One of the most common upgrades triggered by an EICR is a consumer unit replacement. Older fuse boards without RCD protection no longer meet the requirements of BS 7671, and replacing them is the standard solution when the existing unit cannot be upgraded in any other way. In London and the South East, consumer unit replacement typically costs between £400 and £700 for a domestic property, including the new unit, installation, and any associated certification.

The job usually takes around four to six hours and requires the power to be isolated for part of the day, so it's worth planning around it if you're a tenant in occupation.

Retests after remedial work

Once remedial work is complete, your property needs to be re-inspected and signed off to confirm the faults have been resolved. For landlords, this retest must happen within 28 days of the original report. The cost of a retest is typically lower than a full EICR because the engineer focuses only on the circuits and components that were flagged, rather than testing the entire installation from scratch. Expect to pay between £50 and £150 for a standard domestic retest, depending on the scope of the work carried out.

How to get an accurate quote in London

Getting an accurate electrical installation report cost in London starts with giving your electrician enough information before they put a number together. Contractors who quote without asking about your property are almost certainly working from assumptions, and assumptions lead to either inflated figures or a price that changes on the day. The more detail you provide upfront, the more reliable the quote you receive.

Tell your electrician exactly what they're quoting for

Before you contact anyone, gather the basic details about your property: the number of bedrooms, the approximate number of circuits if you know it, the age of the wiring, and whether the property has a modern consumer unit with RCD protection or an older fuse board. If you're a landlord quoting for multiple properties, give each address separately so the electrician can account for differences in size and condition.

Providing accurate property details upfront reduces the chance of your quote changing once the engineer arrives on site.

Let your electrician know about any access restrictions as well. Locked loft hatches, remote meter cupboards, or areas of the property that tenants need to give access to all affect how quickly an engineer can work through the inspection, and that time is part of what you're paying for.

What to look for when comparing quotes

When you receive multiple quotes, compare them on a like-for-like basis rather than simply choosing the lowest figure. Check that each quote specifies the number of circuits being tested, confirms that the engineer holds the relevant qualifications to issue a compliant BS 7671 report, and states whether the final certificate is included in the price.

Quotes that are significantly lower than the market rates outlined in this article often reflect fewer tests, shorter time on site, or an engineer who is not fully qualified to sign off the documentation. A cheap report that misses a Code C1 fault puts you at legal and financial risk that far outweighs what you saved on the initial fee.

Ask about the full scope of the visit

Find out whether the quote covers the entire installation or only certain circuits. Some contractors price for a fixed number of circuits and charge extra if the actual count is higher once they open the consumer unit. Asking this question directly before you confirm the booking removes any ambiguity and protects you from unexpected costs on the day.
