One-bedroom flat — £1,800 to £2,500. Common in city centre conversions, waterfront developments in the Barbican, and purpose-built blocks across Plymouth.
Two-bedroom terraced house — £2,200 to £3,500. Found throughout Mutley, Lipson, St Judes, and Keyham. Typically 8 to 12 circuits.
Three-bedroom semi-detached — £3,000 to £4,500. Very common across Plymouth's post-war estates in Plymstock, Plympton, Honicknowle, and Whitleigh. Typically 12 to 16 circuits.

Signs Your Plymouth Property Needs a Rewire
Plymouth's housing stock includes a unique mix of Victorian and Edwardian properties, post-war reconstruction housing from the 1950s, and more recent suburban development. Properties dating from before 1970 in particular should be assessed by a qualified electrician. Watch out for these indicators.
Rubber-insulated or fabric-braided cables — pre-1960s wiring with deteriorated rubber insulation. This is a C1 (danger present) observation on an EICR requiring immediate remedial action.
Original 1950s post-war wiring — Plymouth's reconstruction properties often contain original rubber-insulated wiring that is now 70 years old and past its safe service life.
Rewirable fuse box — ceramic fuse holders with fuse wire, common in Plymouth's older housing stock. No RCD protection and limited overcurrent protection.
No RCD protection — absence of residual current device protection on socket circuits is a C2 (potentially dangerous) finding under BS 7671 Regulation 411.3.3.
Unsatisfactory EICR — C1 or C2 observations that cannot be resolved economically through targeted repairs indicate a full rewire is needed.
If you are buying a property in Plymouth or planning major renovation work, commission a periodic inspection and EICR before exchanging contracts or beginning work.

What a Full House Rewire Involves
A full rewire replaces all fixed electrical wiring throughout the property. Understanding the process helps Plymouth homeowners plan effectively and set realistic expectations.
First fix — removal of existing wiring, routing new cables through floors, walls, and ceiling voids, and installing back boxes and containment. Involves lifted floorboards and chased or surface-run cable routes.
Second fix — fitting the consumer unit, connecting all circuits, installing sockets, switches, and light fittings. Power is restored at the end of this stage.
Testing and inspection — comprehensive circuit testing to BS 7671 Chapter 64 including insulation resistance, earth continuity, and RCD testing. All results recorded on test schedules.
Certification and notification — EIC issued and Part P notification submitted to Plymouth City Council building control or via the competent person scheme.

Timescales and Disruption
Rewire duration in Plymouth depends on property size and construction. The city's mix of post-war semi-detached houses and Victorian terraces means timescales vary.
Two-bedroom terrace — 2 to 3 days. Plymouth terraces with timber floors and accessible ceiling voids are generally straightforward to rewire.
Three-bedroom semi-detached — 3 to 5 days. Post-war semi-detached houses in Plympton and Plymstock are typically straightforward.
Four-bedroom detached — 5 to 7 days. Larger properties with more circuits and complex layouts.
Victorian granite-built properties — add 1 to 3 days. Mutley, Stoke, and Greenbank properties built from Dartmoor granite are particularly challenging for cable chasing and often require surface-run conduit.
The property will be without mains power during working hours. Plan for this disruption before work begins, particularly if you have medical equipment, pets, or vulnerable household members.
