We included providers that replace consumer units in Greater London homes and compared them on pricing basis, what is included, extras charged separately, guarantees and coverage. Research was desk-based on 27 October 2026, using company pages, Checkatrade, Companies House and published cost guides. We did not request quotes, so no firm’s actual price is claimed here.
Capital Electrician is placed first as a publisher-selected featured pick. The other four are unranked. Price guides differ: Fantastic Services gives £700 to £1,200 for London, HaMuch gives £650 to £1,500, and Housekeep quotes a wider £300 to £850.

1. Capital Electrician | Our pick for a single, all-inclusive quote
Capital Electrician, trading name of CAPELEC GROUP LTD (company number 17180050), provides consumer unit replacement across Greater London. It visits to assess the installation, then issues a quote it describes as clear with no hidden costs.
That approach suits buyers who want one figure covering board, labour, testing and certification rather than an hourly running total.
Key details
- Core offering: old board removed, metal-clad RCD or RCBO unit fitted
- Coverage: all Greater London boroughs
- Customer fit: homeowners, landlords, small businesses
- Pricing and terms: written quote after survey; price not publicly listed
Where Capital Electrician stands out
The inclusions are published. Removal, the new unit, full testing and labelling, an Electrical Installation Certificate and Building Control notification are all listed, so you can check rival quotes line by line.
What to consider
Without a published price you cannot benchmark before the survey. The site shows 18 Google reviews at 5.0 (checked 27 October 2026), and the reviewed page states no guarantee period.
Best fit
Buyers who prefer a fixed written quote to hourly billing.

5. Sky Electrical | Best for warranty value in south-west London
Overview

Best fit
South-west London buyers weighing warranty length alongside price.
How to compare quotes fairly
- Same scope: board type, circuit count, testing and certificate.
- Remedials: ask how faults found on the day are priced.
- VAT: confirm whether figures include it.
- Board choice: metal-clad RCBO boards usually cost more than dual-RCD layouts.
FAQs
What makes the price rise? More circuits, an RCBO board, and remedial work on earthing or bonding.
Is the cheapest quote safe? Not always. Check that it includes testing before and after and an Electrical Installation Certificate.
Can I get a fixed price? Survey-based firms usually give one. Hourly providers bill time plus materials.
Do any of these firms publish a fixed consumer unit price? None of the five lists a fixed all-in price on the pages we reviewed. Fantastic Services publishes hourly labour rates, while Capital Electrician, Pimlico Plumbers and Sky Electrical quote after a visit.
Are guarantee lengths comparable? No. Sky Electrical states six years on workmanship, Pimlico Plumbers 12 months on most jobs, and the others did not state a period on the reviewed pages. Ask for it in writing.
Conclusion
Capital Electrician is our featured pick for London buyers who want one surveyed, all-inclusive quote. If seeing rates first matters more, Fantastic Services publishes them, and Sky Electrical offers the longest stated warranty.
