Conservatory: quick answers
How much does a conservatory cost?
A conservatory typically costs £8,000–£30,000 installed depending on style and size; orangeries run £25,000–£35,000+.
Conservatory or extension, which adds more value?
A full extension usually adds more value and usable space but costs more and needs planning. A conservatory is a faster, cheaper way to add light and space.
Do I need planning permission for a conservatory?
Usually not: most conservatories fall under permitted development if they stay within size limits (single storey, no more than half the garden covered, height limits apply). Listed buildings and conservation areas are the main exceptions. Our conservatory planning permission guide covers the exact rules.
Will it be too hot in summer and too cold in winter?
Older conservatories earned that reputation. Modern glazing changes the picture: solar-control glass, a solid or hybrid roof, and decent ventilation keep summer temperatures manageable, while underfloor heating or a radiator extension handles winter. Budget for these upfront — adding them later costs far more.
