Frequently asked questions

How accurate are these UK cost ranges?
Each range reflects typical 2026 pricing from UK trade quotes, supplier price lists and published industry benchmarks. Regional variation — especially London vs the rest of the UK — can shift quotes by 20–40%, so treat the figures as a sanity-check band, not a fixed quote.
Do the prices include VAT?
Most labour and materials figures shown are quoted excluding VAT, in line with how UK trades typically present quotes. Add 20% VAT for VAT-registered contractors. Some energy-efficiency works (insulation, heat pumps, certain boilers) qualify for reduced 0% or 5% VAT in 2026.
Why do quotes vary so much between tradespeople?
UK quotes vary based on the trade's overheads, day rate, distance, current workload, and whether they sub-contract specialist work. Always get 3 written quotes for any project over £2,000 and compare line-by-line — not just the headline total.
Are these prices for London or the rest of the UK?
Ranges shown are UK national averages. London and the South East typically run 20–35% above these figures; the North, Wales, Northern Ireland and most of Scotland often sit 5–15% below.
Do I need planning permission or building regs for these projects?
Most internal works (bathrooms, kitchens, boilers, rewires) need Building Regulations sign-off but not planning permission. Extensions, loft conversions, new windows in some flats and external alterations may need either or both. Each guide flags the typical requirements for that project.
How do I avoid being overcharged?
Use these reference ranges to spot outlier quotes, ask for an itemised breakdown of labour vs materials, check the trade is on a recognised scheme (Gas Safe, NICEIC, TrustMark, FMB), and never pay more than 20–30% up front on a project under £10,000.
