Fuse board FAQs (Tower Hamlets)
How much does a fuse board upgrade cost in Tower Hamlets?
+
£750 all-in for a 6–12 way Type A RCBO consumer unit across Tower Hamlets (E1, E2, E3, E14). Same price as our London-wide standard — no postcode surcharge.
How long does a board change take in Tower Hamlets?
+
Typical 6–12 way domestic upgrade is 4–6 hours on site. Power is off for most of that. We dispatch engineers daily across East London, including Tower Hamlets.
Will the new board satisfy my Tower Hamlets letting agent?
+
Yes — full NICEIC installation certificate and minor works documentation included. Accepted by every London letting agent we work with.
Do I need to upgrade if my Type AC board passed the last EICR?
+
Not necessarily. If your EICR coded only C3 (improvement recommended), you can wait until your next renewal cycle. If you've installed an induction hob, EV charger or home battery, we'd recommend bringing the upgrade forward — those loads demand Type A protection.
