Cost by style (supplied & fitted)
What affects the price
- •Size and style — a simple lean-to is the cheapest; an orangery with a lantern roof is the most expensive.
- •Roof type — a solid (warm) roof costs more than glass or polycarbonate but makes the room usable year-round.
- •Base and groundworks, especially on uneven or sloping ground.
- •Glazing spec, doors (French or bifold) and any dwarf brick walls.
- •Electrics, heating and flooring to make it a usable room.
Regional price variation
Labour is the biggest regional swing. London and the South East typically run 20–30% above the national average, while the North of England, Scotland and Wales tend to sit 5–15% below it. Material prices are fairly consistent nationwide — it is day rates that move the total. The ranges on this page assume South of England pricing unless stated.

Frequently asked questions
How much does a conservatory cost in the UK?
A conservatory typically costs £8,000–£25,000 fitted. A lean-to is £8,000–£15,000, Victorian and Edwardian styles £10,000–£20,000, and an orangery £15,000–£30,000. A solid warm roof adds £3,000–£8,000.
Do I need planning permission for a conservatory?
Most conservatories fall under permitted development within size and height limits, so they do not need planning permission. Larger conservatories, those on the front of the house, or in conservation areas may need approval — check with your council.
Is a solid roof worth it?
A solid (warm) roof costs more but greatly improves insulation, so the room stays usable in winter and summer rather than being too cold or too hot. Many people upgrading an old conservatory choose a solid roof for exactly this reason.
