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.
