Choose the job you are thinking about and a size, and the calculator below gives a typical UK price range. The ranges come from the same figures used across this site: a roof repair can cost as little as £150, while a large bespoke new conservatory can reach £30,000.
How to use the three sizes
- Small: a simple fix or a compact room, such as a single gasket, a small lean-to or a blinds-and-film upgrade.
- Typical: a standard-size conservatory, such as a Victorian or Edwardian, or the usual version of a roof, refurbishment or insulation job.
- Large: a complex, bespoke or high-specification job, such as a P-shape room, a roof with valleys, or a full set of upgrades.
The figures are guides for budgeting. Your base, the roof shape, access and the specification you choose all move the price, so a survey and a written quote are the only way to get a firm number.

Frequently asked questions
How accurate is the conservatory cost calculator?
It gives a typical range for each job and size, as a guide only. The final price depends on your base, roof shape, access and chosen materials, so treat it as a starting point for comparing quotes.
Does the calculator include VAT?
The ranges are broad guides, so check whether each quote you receive includes VAT and any extras such as scaffolding and waste removal.
Which conservatory job is the cheapest?
A roof repair is the cheapest, from around £150. Comfort upgrades such as blinds and film come next, and a new conservatory or solid roof costs the most.
