Conservatories Building Regulations
In general domestic conservatories are exempt under UK building regulations. We have listed below some of the exemptions requirements under building regulations 1991 (as amendments). This criteria must be met for a conservatory to be classified as exempt.
Conservatories are normally exempt from building regulations when:
✓ Built at ground level
✓ Conservatories are less than 30 square metres in floor area
✓ At least 50% of area that will form the external boundary / edge of the conservatory must be glazed and 75% of the roof area to be covered with either glass or polycarbonate
✓ All conservatories must be separated from the house by an external quality door, patio door or French doors.
✓ Glazing and the electrical installation must comply with IEE and building regulations
It is not recommended to build conservatories where they will hamper ladder access to windows serving quarters in roof or loft conversions, principally if any of the windows are proposed to help escape or rescue in a fire situation.
Any new structural opening linking the conservatory to the house will necessitate building regulations approval, even if the conservatory is an exempt building. Click for more information on conservatory planning permission.
