What the wiring looks like in a Kensington terrace

Victorian terraces were built before electricity existed. The wiring was added later, run through wall cavities, under timber floors, and sometimes across ceiling voids in ways that made sense at the time but create real problems now. When one circuit fails in a terrace, the effect is rarely isolated. Half the upstairs goes dark, or a single fault takes out multiple rooms.

The other issue is what you find when you open things up. Cotton-covered wiring and ceramic fuses. It’s out dated and even dangerous

Heritage overlay adds another layer. External surface mounting of conduit and cable isn’t always acceptable on a heritage property, and the routing decisions that are fine on a standard home need more thought here. We work within those constraints rather than taking the easiest cable run and leaving it for the owner to deal with later.

Rewiring a Kensington terrace — why partial rewires so often fail

A partial rewire sounds like a reasonable middle ground, but in a terrace the wiring runs through the same limited access points throughout the house — and once you’re in the cavity pulling cable, the cost difference between replacing the problem circuits and doing the whole job is often smaller than expected. What gets left behind is the real risk: ageing cable in cavities you can’t easily inspect, waiting to fail two years down the track.

Access drives the decision more than anything else. Suspended timber floors mean underfloor access, which makes rewiring far less disruptive. Concrete slabs are a different job entirely. We’ll assess the access before recommending a scope — not after you’ve committed to one.
