Estimates are a guide, not a fixed quotation. A free survey confirms specification, access and frame condition.

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

    The calculator allows £450 per roof window and £850 for a plastered ceiling ready to decorate. The survey confirms the specification.

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.
It is an indicative calculation, not a guaranteed quote or a measured accuracy promise. Frame condition, structural work, access and chosen finish can change the final price. A free home survey confirms your specification and fixed written quotation.
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.
The estimate includes the SupaLite system, tiles and insulation, plus the selected skylights and plastered ceiling allowance. A ceiling is included only when selected. Replacement quotes confirm survey, scaffolding, removal, guttering, flashing and Building Regulations sign-off, with 10-year insurance-backed and 40-year tile manufacturer guarantees. Any frame work is assessed separately.
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, so you're never paying for work that hasn't been done.
