In Tower Hamlets, consumer unit upgrades split between two needs: bringing the borough’s old period-terrace boards up to standard, and fitting HMO-grade boards (now with AFDDs) for the borough’s shared housing. GFL Electrical carry out NICEIC-certified fuse box replacement across the borough.
Two kinds of board upgrade
- Period terraces (Spitalfields, Bethnal Green, Bow): older homes with rewireable fuse boards or no RCD — straightforward upgrades to modern RCD/RCBO protection.
- HMOs and shared houses: these now require AFDDs on socket circuits under BS 7671, so an HMO board upgrade is more involved (and costs a bit more) than a standard home — see our HMO EICR/AFDD guidance.
- Leasehold flats: older flat boards that need upgrading, often prompted by an EICR.
What an upgrade delivers
- RCD/RCBO protection for fast shock and fire safety
- Per-circuit RCBOs so a fault doesn’t black out the whole property — see our RCD vs RCBO guide
- AFDDs where required for HMOs
- BS 7671 compliance and full certification

Common questions about fuse box replacement in Tower Hamlets
I let an HMO — does the new board need AFDDs? Yes — socket circuits in HMOs now require AFDDs, so we’ll fit an HMO-compliant board.
Why does an HMO board cost more? AFDDs are more expensive than standard breakers — it’s a regulation-driven cost, not an upsell.
My period terrace has a wire-fuse board — dangerous? It lacks modern shock protection; upgrading is strongly recommended.
