House Rewire Cost Bristol: 2025 Price Guide

Bristol Rewire Costs by Property Type (2025)

• 2-bed terraced house: £2,500–£4,000 (3–5 days)
• 3-bed semi-detached: £3,500–£5,500 (5–7 days)
• 4-bed detached: £5,000–£8,000 (7–10 days)
• Large period property (5-bed+): £8,000–£13,000+ (10–15 days)

• Victorian terraces (1860s–1900s): Clifton, Redland, Totterdown, Montpelier, Bedminster, Southville, and Kingsdown. Lath-and-plaster walls, solid ground floors in many, and split-level layouts on hillside plots make cable routing more complex. Ad-hoc wiring additions from previous decades are common — an EICR often reveals circuits from multiple different eras.
• Edwardian semis (1900s–1910s): Common in Horfield, Filton, Brislington, and Knowle. Slightly easier to rewire than Victorian terraces due to accessible loft spaces and lighter wall construction, but similarly likely to have original VIR (vulcanised india rubber) wiring.
• 1930s–1950s semis and detached: Found across Henleaze, Westbury-on-Trym, Bishopsworth, and Nailsea. Accessible loft spaces and moderate wall depths. Many still have original PVC wiring from the 1950s–1960s without earthing on lighting circuits.
• 1960s–1980s council and private estates: Hartcliffe, Withywood, Lockleaze, Southmead. Plasterboard or large-panel construction — relatively straightforward to rewire. Consumer units often have BS 3036 rewirable fuses or early single-RCD boards.
• Converted flats (Victorian houses): Common across Clifton, Cotham, and Redland. Quality varies enormously — many have shared circuits, undersized sub-mains, and wiring from multiple different eras. An EICR is essential before scoping any rewire in a converted flat.

• New consumer unit — metal enclosure with RCBOs or dual-RCD arrangement, surge protection device (SPD), and main switch.
• All circuit cables — twin and earth for ring finals, radials, lighting circuits, cooker, shower, and immersion heater circuits.
• Accessories — sockets, switches, ceiling roses, and fused connection units. Standard white plastic is included; upgraded finishes are charged extra.
• Earthing and bonding — main earth conductor, main bonding conductors to gas, water, and oil pipework.
• Testing and certification — initial verification testing of every circuit, the Electrical Installation Certificate, and Part P notification.

• Wall chasing creates dust and debris — electricians use angle grinders or chasing tools to cut channels for cables. In a Victorian Bristol terrace with lath-and-plaster, this generates significant dust that spreads throughout the property.
• Power is off during first fix — the supply is isolated while new circuits are installed. Plan for no cooking, heating, or power for several days. Many Bristol residents stay with friends or family during this phase.
• Replastering is a separate cost — after the chases are filled, plastering is typically done by a separate plasterer. In period Bristol properties, lime plaster matching is a specialist skill. Budget £500 to £1,500 for making good on a full rewire, plus decoration.
• Access to all rooms required — the electrician needs access to every room throughout the job. Clear furniture and valuables away from walls and cover items that cannot be moved.

• Verify NICEIC, NAPIT, or ELECSA registration — search by Bristol postcode on the scheme's online register. Non-negotiable for Part P compliance.
• Ask about Bristol Victorian terrace experience — hillside terraces in Clifton, Totterdown, and Kingsdown require specific knowledge. Ask for references from similar Bristol properties.
• Get at least three comparable quotes — compare on a like-for-like basis. Ensure each quote specifies consumer unit type, number of circuits, and whether making good is included.
• Confirm minimum £2 million public liability insurance — ask for a copy of the certificate before work starts.
• Check that EIC and Part P notification are included — mandatory for all rewires in England. If absent from the quote, the quote is incomplete.
