Conservatory Cost Calculator
Estimate the cost of a new conservatory — lean-to, Victorian, Edwardian or orangery — by floor area, with dwarf wall and electrics/heating add-ons and a typical price range.
Estimate only. This is an indicative estimate, not a quote — always get quotes from local installers before committing to a project. Prices vary by region, glazing specification, ground conditions and finish quality, and larger conservatories may need planning permission or building regulations approval.

How conservatory costs are estimated
A conservatory's cost is driven mainly by its style: a lean-to is the simplest shape and the cheapest to build; Victorian and Edwardian conservatories add a more elaborate, multi-faceted roofline; an orangery — part-brick, part-glazed, with a flat roof lantern — typically costs the most. We multiply an indicative supply-and-fit rate per square metre by your floor area, add a base and foundations allowance included on every job, then let you add a dwarf/low wall (priced per m² of floor area) and an electrics and heating allowance. Because ground conditions, glazing specification and finish quality vary from job to job, we show a typical range (±15%) alongside the headline estimate — always get quotes from local installers before committing to a project.
