UK home improvement cost index 2026
Last updated 14 July 2026Typical UK costs for the most common home improvement jobs. These are national typical ranges: the middle band of what people actually pay, with the cheapest and priciest outliers stripped out. Every figure lines up with the detailed breakdown on the linked cost page. Journalists and researchers are welcome to use these, and all we ask for is a credit and a link.

Where you live changes the price by about a third
The same job does not cost the same across the country. London runs around 25% above the national average, while the North East and Wales sit around 10% below. In practice that is a gap of roughly a third between the priciest and cheapest regions for identical work. A £10,000 fitted kitchen is nearer £12,500 in London but closer to £9,000 in the North East.

Contractor price submissions
UK tradespeople can submit their typical prices for specific job types in their region. We verify their business credentials before any data goes live - Companies House registration for limited companies, or sole trader details for individuals. Trade-specific accreditations (Gas Safe, FENSA, NICEIC, etc.) are checked where applicable.
We publish each contributor's business name in the Trusted Contributors section on relevant pages, along with the date their data was last updated. Contributor data is anonymised before being included in regional averages - we don't show individual quotes as a public price list.
We ask contributors to update their prices at least once a year. Stale submissions (over 18 months old) are flagged and removed from the averages until updated.
Researched market data
Where contractor submissions are limited - particularly in the early stages of the site - we supplement with research from industry bodies, trade association published rate cards, and government data where available. We clearly label which data is research-based vs. contributor-sourced.
Sources we reference include the Office for National Statistics construction output data, the Federation of Master Builders' State of Trade Survey, BCIS (Building Cost Information Service) published benchmarks, and manufacturer-published installation cost guidance from boiler and window manufacturers.
How we calculate averages
For each job type and region, we take the middle 80% of submitted prices (removing the lowest 10% and highest 10% to exclude outliers), then calculate the median and interquartile range. The "typical price" shown on cost pages is the median; the price range reflects roughly the 25th to 75th percentile.
Regional multipliers for the London premium and lower-cost regions are calibrated against ONS construction output data and cross-checked against our own submissions where volume permits.
How often we update
Each cost page shows a "Last updated" date. We review core prices at minimum quarterly, and update following significant market events - energy price changes affecting boiler demand, material cost spikes (timber, steel), or major changes in labour costs.
All pages are reviewed annually as standard. Pages flagged by readers as inaccurate get priority review within 5 working days.
Commercial disclosure
Less.co.uk earns money in two ways. Our cost pages include a free quote service - when you request quotes, we may receive a referral fee from our lead generation partner. You pay nothing for this and are under no obligation. Some DIY and materials pages also contain affiliate links, clearly labelled near the link. Neither relationship influences our pricing data, editorial content, or the order in which information appears.
Something look wrong?
If you've recently had a job done and the price looks nothing like what we've published, please tell us. It's genuinely useful - either there's a data problem we should fix, or there's a local market factor worth explaining.
