UK Home Improvement Costs 2026 (155 jobs, with regional breakdowns)

Independent guide prices for the 155 most-searched UK home-improvement jobs, from a new boiler or loft conversion to a resin driveway or double glazing, published by Costwise. Each job carries a realistic "from", "typical" and "up to" price in GBP, the pricing unit, a typical on-site timeline, and the month its figures were last reviewed, plus a regional breakdown.

Files

uk_home_improvement_costs.csv — one row per job (n=155).

uk_regional_costs_long.csv — tidy long format, one row per job x region (n=620). Regions and multipliers vs the UK average: Midlands / East (UK average) ×1, London ×1.2, South East / South West ×1.05, North / Scotland / Wales ×0.97. Figures are the UK-average band scaled by the multiplier and rounded to guide-price steps, matching the regional tables published on each Costwise guide.

Methodology and provenance

These are researched guide prices, not a statistical survey. Each price band is built from current UK supplier and installer pricing, industry cost data and published market figures, then sense-checked against what real jobs of that type cost. Prices are reviewed and dated (see prices_reviewed; this release spans June to September 2026) and only changed when the underlying figures move, never cosmetically. Regional figures apply the same multipliers used by the Costwise cost calculator. The multipliers were benchmarked in September 2026 against ONS Annual Survey of Hours and Earnings 2025 median pay for skilled construction and electrical trades, job-weighted into the four regions, with a stated allowance for London and South overheads; the working is on the methodology page.

Guide prices describe a typical job, not a quote: any individual job varies with property, spec and access.
