Refurbishing a conservatory typically costs £1,500 to £7,000. That buys a dated but structurally sound room a new lease of life: replacement side glazing and doors, renewed sills and fascias, repairs to dropped doors and stuck vents, a frame respray or a new floor. It costs far less than starting again, as long as the base and frame are in decent order.

TypicalNew side glazing and a set of doors, renewed sills and fascias, re-sealed or re-gasketed roof edges£3,000 – £5,000

What drives the price

  • How many openings. Each replacement window or door is a made-to-measure unit, and the count matters more than the room size.
  • Frame condition. A respray works on sound frames. Warped or cracked uPVC cannot be sprayed back to health.
  • Glass. Upgrading to modern double glazing with a low-emissivity coating costs more than like-for-like, but changes how the room feels.
  • Flooring. A new tiled or laminate floor is often the biggest single extra, and a damp or uneven base must be sorted first.
  • Hidden defects. Rot in timber sills or dropped frames often turns up once old units come out.

When refurbishment is not enough

If the base has moved, the frame has bowed or the roof is failing, new doors will not fix the room, and the money may be better spent on a rebuild or a new roof. As a rough test, once a refurbishment quote passes about half the cost of a new conservatory, it is worth asking for a price on starting again. Our warning-signs checklist shows which problems point to a bigger job, and the repair or replace decision guide takes the next step. For a new build, see our new conservatory cost guide.

Order of work matters

Fix weatherproofing and structure first, then the cosmetic jobs. Painting a frame or laying a floor under a leaking roof wastes the money. The Checkatrade conservatory refurbishment cost guide offers a second set of figures to compare against.

Frequently asked questions

Is it cheaper to refurbish or replace a conservatory?

Refurbishing is usually much cheaper if the base and frame are sound. If they are not, the money tends to go further on a rebuild.

Can uPVC conservatory frames be resprayed?

Yes, sound frames can be professionally sprayed in a new colour, which is often far cheaper than replacing them. The specialist should clean and prepare the frame properly first.

How long does a conservatory refurbishment take?

Typically 2 to 7 days on site, depending on how many units are replaced. Made-to-measure windows and doors add a lead time beforehand.

Will refurbishing make my conservatory warmer?

New double glazing, better seals and fixing draughty doors help. A bigger improvement usually needs the roof and floor tackled too, which is covered under insulation.
