Rewiring Cost UK

Figures are typical UK averages including labour, materials, and VAT at 20% for standard-rated work.

Typical UK Cost Ranges for Rewiring

All prices are approximate UK averages including labour, materials, and VAT at 20% (2026). Some qualifying renovations for empty homes may use the reduced 5% VAT rate.

Real UK Cost Examples

• Budget scenario (2-bed flat, Nottingham): focused essentials and practical finishes. Not done: major layout or structural changes. Approx cost: £2,375 to £4,000.
• Mid-range scenario (typical homeowner, 3-bed semi): balanced specification with core upgrades and reliable materials. Approx cost: £4,250 to £5,750.
• High-end scenario (3-bed terrace): premium materials and wider scope with higher coordination demands. Main cost drivers: specification level and complexity. Approx cost: £6,000 to £8,400.

What You Can Get For Your Budget

• Around £3,500: core refresh and essential upgrades, usually with no major layout change.
• Around £5,000: balanced refit scope with better materials and targeted performance improvements.
• £7,500+: wider flexibility on finish quality, scope depth, and more complex works.

Hidden Costs to Watch For

• Consumer unit upgrades and testing/certification can add late-stage compliance spend.
• Waste removal, making-good, and repeat trade visits are common late-budget increases.
• Compliance and certification items are often missing from initial summary quotes.
• In most UK projects, scope changes after works start are where costs escalate fastest.

Should You Do This Renovation?

• Usually worth it when rewiring solves a clear usability, compliance, or energy-performance problem.
• Less worth it when the main issue is cosmetic and resale timing is short-term.
• ROI is strongest when scope is disciplined and specification matches local value levels.

Common Cost Mistakes

• Underestimating labour and preliminaries while focusing only on material prices.
• Changing scope mid-project without budget re-baselining.
• Choosing the cheapest quote without checking detailed inclusions and exclusions.
• Running too little contingency for hidden defects and compliance upgrades.

Key Cost Factors

• Property size and number of rooms — more circuits mean higher cost.
• Access — solid floors and finished ceilings make rewiring more expensive.
• Consumer unit — modern RCD/RCBO boards are required.
• Number of circuits — kitchens and bathrooms need more dedicated circuits.
• Whether walls need chasing and making good.
• Location — London and the South East typically cost more.

Cost Checkpoints

Use these checkpoints to sequence spend decisions, protect your core scope, and reduce late-stage budget overruns.

• Prioritise full rewire (4-bed detached) first: typical range £6k to £9.6k can shift the whole project budget if scope changes late.
• Prioritise full rewire (3-bed) next: typical range £4.2k to £7.2k can shift the whole project budget if scope changes late.
• Use £5k as a working midpoint and hold a contingency of roughly 10% to 15% for unknowns and making-good works.
• Request like-for-like quotes with labour, materials, and exclusions split out so you can compare options without hidden scope gaps.

Ways to Reduce Costs

• Get at least three quotes from NICEIC or NAPIT registered electricians.
• Plan socket and switch positions before first fix to avoid changes later.
• Do decoration and making good yourself after the rewire if you're able.
• Rewire before plastering and finishing so cables can be chased in.
