Costwise is an independent guide to what home improvements really cost in the UK. For each of the most-searched jobs, from a new boiler or a loft conversion to a resin driveway or double glazing, we publish an honest price range: a realistic from, a typical figure most people pay, and an up to for larger or higher-spec work. Every figure is built from real UK job pricing, reviewed and dated, and only changed when the numbers actually move.

Each guide breaks the job down: what is included in a normal price, what quietly pushes it up, roughly how long it takes, and how prices differ by region. A built-in calculator lets you tailor the range to your own job, and every page answers the questions people ask before they commit. We only earn if you choose to act, through installer introductions, a few marked affiliate links, our optional project pack and My Home subscriptions, and none of it changes the prices or advice you see.
