EICRs and electrical safety checks in Harrow
We carry out EICRs (electrical installation condition reports) for landlords, letting agents and homeowners in Harrow and across north-west London. Every circuit is tested, every observation is coded and explained, and any remedial work is quoted separately, so you get a report you can rely on and send straight to tenants or the council.

Three in ten Harrow homes are rented privately
At the 2021 census, 29.6% of Harrow households rented privately, up from 21.7% in 2011. Each of those homes needs an EICR at least every five years, a copy for every tenant, and remedial work inside 28 days when the report is unsatisfactory. Our landlord EICR page sets out the process. Source: ONS.
Licensing across Harrow
Harrow extended selective licensing to six wards in 2026: Edgware and Roxeth from 2 May, Greenhill and Marlborough from 6 July, and Wealdstone North and Wealdstone South from 1 September. Each designation lasts five years and covers every private let in the ward. Harrow’s borough-wide licensing of smaller HMOs ran from August 2021 to 5 August 2026; the council consulted on renewing it, so check the current position before letting to sharers. Licensing does not change the five-yearly EICR, but the council knows where licensed lets are and can ask to see the report, which you then have 7 days to send.

Metro-land homes and their wiring
Harrow was called the capital of Metro-land, the suburbs the Metropolitan Railway promoted from 1915, and its estates company built Harrow Garden Village among others. Homes from that boom were wired with rubber-insulated cable, which the IET says was in general use until the early 1950s and is now often hardened and brittle. Most have been rewired since, but concealed cable often survives several upgrades behind newer sockets and switches. A home EICR shows which you have. Sources: Wikipedia, Metro-land; IET Wiring Matters.
What changed in April 2026
Amendment 4 to the wiring regulations, BS 7671, was published on 15 April 2026 and became the only current version on 15 October 2026. It splits the observations on an EICR into two parts, and an FI (further investigation) no longer makes a report unsatisfactory by itself. For landlords, the government guidance still says further investigation identified on a report must be carried out within 28 days, so an FI remains a job to book. EICR codes explained covers the detail. Sources: NICEIC; GOV.UK.

Common questions
How quickly can you do an EICR?
Ring 020 8194 2001 with the postcode and we give you the next available times. Tell us if you are working to a tenancy start date or a 28-day deadline.
What does a landlord EICR cost?
It depends mostly on the number of circuits. Tell us the property type and postcode for a price, and see what changes the price.
Do you fix the problems the report finds?
Yes, as a separate quote, item by item. You are free to use another electrician for the remedial work if you prefer.
Can you do the PAT testing on the same visit?
Yes. One visit means one set of arrangements with your tenants.
