Building Regulations

If your conservatory’s internal floor area is less than 30 square metres you probably do not need to apply for building regulations approval

The regulations say you need to apply if:

- The internal floor area is greater than 30 square metres.

- The glazing materials used do not meet the requirements of Part N
(“Glazing – safety in relation to impact, opening and cleaning”).

- The access from the house into the conservatory or orangery is of a size that effectively makes the structure an integral part of the house. In such circumstances special requirements may apply.

- Less than 75% of the roof area is glazed and/or less than 50% of the sides are glazed in which case the new structure would be construed as an extension (as opposed to a temporary structure).

- Any fixed electrical installation does not meet the requirements of Part P (“Electrical safety”).
