From £550
supplied and fitted, up to 10 ways. Includes certification and Part P notification.
This is our most common Streatham job. The 1930s semis very often still have a 1970s or 80s wall-mounted board with rewireable fuses and no RCD anywhere, which is both an automatic EICR failure and the genuine safety issue it looks like. These are usually clean replacements: eight to ten circuits, an accessible board position in the hall or under the stairs, and a full day. The one thing that regularly adds cost is that the earthing at the intake is often the original 1930s arrangement and needs bringing up to standard at the same time — we check before quoting so the price does not move.
The property types we see in Streatham
The 1930s semis around Streatham Vale and Furzedown are the defining stock — bay-fronted, cavity-walled, with generous loft space and accessible floor voids, which makes them the easiest properties on our patch to work in. Their weakness is the vintage of their last upgrade: a great many were partially rewired in the 1970s or early 80s, which means PVC cable that is genuinely old, wall-mounted fuse boxes of that era, and lighting circuits with no earth. Telford Park is larger Edwardian housing, much of it still whole houses. Streatham Hill has interwar mansion blocks with communal risers and, in several cases, original 1930s intake positions still in service.
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 Streatham
Streatham is the furthest south we go and the response time reflects the run down the A23. Parking is markedly easier than the rest of the patch — much of SW16 is uncontrolled or lightly controlled, and most 1930s houses have a driveway, which makes van access simple and keeps costs down. The Streatham Hill mansion blocks need porter access for intake cupboards.
