Do I need Building Regulations approval for a conservatory? Generally speaking conservatories on residential property are exempted under Building Regulations in England and Wales. If you live in Scotland or Northern Ireland your installer will be able to advise you.

Below are some of the Exemption Criteria - under the Building Regulations 1991 (as amended). These criteria must be met for a conservatory extension to be classed as exempt:

1.The conservatory has a completely transparent or translucent roof (ie. glass or polycarbonate).

2.The walls are substantially glazed. (should not have more than 25% of its wall area as brickwork)

3.A floor area not exceeding 30 sq.m.

4.The conservatory is at ground level.

5.A door separates the house from the conservatory.

6.Radiators are controllable within the conservatory and have separate temperature and on/off controls.

7.All glazing satisfies Part N, schedule 1 for toughened/safety glass.

8.There is no sink, toilet or plumbed in electrical appliances such as washing machines or dishwashers.

9.If you want to move an inspection chamber - please also check Bylaws and restrictive covenants.
