The business
London EICR Certificates is one of our own businesses: electrical safety certificates (EICRs) for landlords and businesses in London. We designed, built and operate it. That is why it is here. Every service we sell was tested on businesses like this one first.
What we built
A search-led service website that captures enquiries and coordinates qualified electricians. It is being rebuilt on a modern Next.js platform.
On the live site today the homepage leads with "EICR Certificates in London" and the search result title reads "EICR London from £89 + VAT | Book Online".


Measured, not claimed
We ran the homepage through Google PageSpeed (mobile test) and the VAULT Business Audit on 12 November 2026. These are the numbers as measured on that day. Scores move from test to test, so treat them as a snapshot, not a promise.

Search visibility
We track this site's Google rankings in the UK (English, mobile results) with Semrush Position Tracking across 150 target keywords. Figures below are for 12 August to 12 November 2026, read on 12 November 2026.
| Measure | Result |
|---|---|
| Visibility | 26.31% (down 2.01 points over the quarter) |
| Keywords in the top 3 | 45 of 150 |
| Keywords in the top 10 | 71 of 150 |
| Keywords in the top 20 | 88 of 150 |
| Keywords in the top 100 | 114 of 150 |
| Improved vs declined | 51 improved, 64 declined |
It ranks first for searches including "book eicr london", "commercial electrical inspection london" and "commercial electrical testing london".
The biggest weakness is the "failed EICR" topic, where visibility fell sharply, and keyword cannibalisation: Semrush flags 80 of 108 ranking keywords as having more than one of our pages competing for them. Consolidating those pages is the next fix.
Visibility estimates the share of possible clicks the site wins across the tracked keywords, so 100% would mean first place for every one. It moves daily, so we read it as a trend.
What our own audit told us
We point the same audit at our own work that we point at yours. On this site it flagged these priorities:
- Analytics installed: Without analytics you cannot see where visitors come from or which pages produce enquiries.
- Live chat or assistant: Visitors with a quick question often leave rather than fill in a form. A chat assistant can answer at any hour and capture the enquiry.
- Page size (HTML): Very large HTML usually means inline code or builders adding bulk. It slows phones down.
We are not hiding them. Fixing them is the next step on this project, and it is exactly the kind of work we do for clients. The most important one across our portfolio is tracking: without analytics you cannot prove which pages and channels bring enquiries, so you cannot invest with confidence.
Business results
Pending verified figures. We will add enquiry volumes, response times and jobs won only when they can be checked against real records. We do not publish estimates as results. Read our editorial policy.
