Many conservatories need none of these. In England, a single-storey rear conservatory within the permitted development limits needs no planning application, and one under 30 m² that is separated from the house and not heated by the house’s system is exempt from building regulations. In Scotland, a conservatory of 8 m² or less that is at least 1 metre from a boundary needs no building warrant. Conservation areas, listed buildings and flats change the picture, which is what the city guides below cover.
Why quotes differ
- Size and shape. Every extra square metre adds frame, glass and base; Victorian and Edwardian shapes use more parts than a lean-to.
- Roof. Polycarbonate, glass and solid tiled roofs differ in price, and a solid roof can bring building regulations into play.
- Groundwork. Checkatrade lists groundwork, preparation and disposal as normal quote items; poor ground, trees or a drain under the base add cost. See conservatory foundations.
- Extras. Blinds (Checkatrade reports an average of around £2,650), flooring, electrics and heating are often priced separately.
- Access and waste. Skips, parking and access equipment appear as extras in some quotes.
