Conservatories & sunrooms · Northampton

How much does Conservatories & sunrooms cost in Northampton? (2026 price guide)

A small uPVC lean-to conservatory typically costs £6,000-£10,000, a mid-size Victorian or Edwardian-style conservatory usually runs £10,000-£18,000, and a larger orangery-style sunroom with a solid insulated roof can cost £20,000-£35,000 or more.

Costs depend on size and roof type such as glass, polycarbonate or solid tiled, frame material, foundation and base work required, and whether planning permission or building regulations approval is needed.

A solid insulated roof costs more upfront but can reduce heating costs and make the space usable year-round, so it is worth weighing against a standard glass roof when comparing quotes.
