How the calculator works

It uses the same figures we quote from on real Plymouth, Devon and Cornwall installs — base price by shape, a size multiplier, then extras.

  1. 01

    Choose your shape

    Lean-to, Victorian, Edwardian, P-shape or gable-end — each has its own base price because of the ridge and hip work involved.

  2. 02

    Pick your size

    Measure the internal floor. Up to 3m × 3m is small, ~3.5m × 3.5m medium, 4m+ large.

  3. 03

    Add skylights and finish

    Roof windows are £450 each fitted. A plastered ceiling adds £850 and gives a smooth painted finish inside.

  4. 04

FAQ

Conservatory roof calculator questions

How the pricing works and how accurate it is.

Pick your conservatory shape, its rough size, how many skylights you want and whether you'd like a plastered ceiling. The calculator applies the same base prices, size multipliers and extras we use when quoting in Plymouth, Devon and Cornwall, and returns a fully fitted price range. It takes about 30 seconds and needs no email address.
For a standard conservatory it is usually within 10% of the final fixed quote. It is based on real 2026 installs, not national averages. Prices can move outside the range if the existing base or frame needs strengthening, access is very tight, or you choose a premium slate or metal tile finish. Your fixed price is confirmed after a free home survey.
A fully fitted insulated tiled conservatory roof starts from £6,000 and most projects land between £7,300 and £15,000. A 3m × 3m lean-to sits at the lower end; a large Victorian or P-shape roof with skylights and a plastered ceiling sits towards the top.
Free survey, scaffolding, removal and disposal of the old roof, the complete SupaLite™ warm-roof system, lightweight tiles, insulation, new guttering, code-4 lead flashing, an internal plastered ceiling ready to decorate, Building Regulations application and sign-off, and a 10-year insurance-backed guarantee.
Measure the internal floor from wall to wall in both directions. Up to roughly 3m × 3m is small, around 3.5m × 3.5m is medium, and 4m or more is large. You do not need the roof pitch or panel sizes — we take those at the survey.
No. The calculator shows your price range on screen with no email, no phone number and no follow-up calls. Contact us only when you want a fixed written quote.
As a rough guide, a fitted SupaLite™ warm roof works out at roughly £650–£850 per m² of roof area once scaffolding, plastering and Building Regs are included. Smaller roofs carry a higher rate per m² because fixed costs like scaffolding are spread over less area.
Yes. Stage payments are standard — a small deposit secures your date, with the balance split between start of work and completion — and finance is available through a regulated partner with terms from 12 months to 10 years.
