The Tonsleys cottages are the quickest consumer unit replacements we do — six to eight circuits, board usually in an accessible hall cupboard, comfortably a single day. The complication is that many still have a 60A main fuse, which is fine for the existing load but becomes the binding constraint the moment anyone wants an electric shower or an EV charger. We flag it at the time so you can decide whether to apply to UK Power Networks for an upgrade while the board is already off. Riverside flats have modern boards already and rarely need this.
The property types we see in Wandsworth
The Tonsleys are 1850s–1870s two-up two-down cottages, small, solid-walled and with almost no floor void — which makes every cable run a chase. Southfields is the 1900s grid between the common and the district line, larger and mostly still whole houses. Earlsfield is smaller Victorian terrace, heavily converted to flats. The riverside developments — Ram Quarter, Wandsworth Riverside Quarter — are new-build with three-phase supplies, heat networks and, importantly for us, sprinkler and alarm interfaces that mean electrical work often has to be coordinated with the building's fire strategy.
What fuse board replacement involves
Replacing a consumer unit takes most of a day and costs from £550 for a standard flat. If you still have a board with rewireable fuses, no RCD protection, or a plastic enclosure, it no longer meets the current standard and is the single most worthwhile electrical upgrade in an older London property.
You need us if
- A board with old-style rewireable fuses or ceramic fuse carriers
- No RCD protection — no test button anywhere on the board
- A plastic or wooden enclosure (metal has been required since 2016)
- Breakers that trip and cut power to half the flat at once
- No spare ways left for a new circuit, shower or EV charger
- An EICR that coded the board C2
What's included
- Full metal-clad consumer unit with individual RCBOs per circuit
- SPD (surge protection) fitted as standard
- Every existing circuit tested before and after — faults found, not hidden
- Main earthing and bonding brought up to standard where needed
- Circuits labelled properly so you can find the right breaker
- Electrical Installation Certificate plus Part P building control notification
The standard we work to
Fitted to BS 7671 (18th Edition) Amendment 2, with a metal enclosure to Regulation 421.1.201 and notified to building control under Part P.
Getting to you in Wandsworth
Wandsworth is our furthest patch and the response time reflects the traffic on Trinity Road and the one-way system rather than the mileage. Old York Road and the Tonsleys have very limited parking and narrow streets. The riverside blocks all require concierge sign-in and most require a permit to work for anything beyond a basic repair, which we handle but which needs a day's notice.
