Do I need Building Regulation Approval to construct a conservatory?

Building Regulation approval is not required for a conservatory providing the internal floor area is 30 m2 or less, and also, not less than 75% of the roof and 50% of the walls are constructed with a translucent material (e.g. glass or PVC). In addition to this the exempt conservatory should be thermally separated from the existing dwelling with an external quality door, not have a fixed heating system installed, the doors and windows should be toughened/laminated safety glass (where applicable), should not be built over a Public Sewer and no new electrical circuits should be provided
You can find out if there are any Public Sewers on your property, by contacting Northumbrian Water Ltd

If you do install a new electrical circuit (lighting or power), the electrical work is required to comply with Part P of the regulations, therefore unless the work is carried out by a "Competent Person" (refer to Part P guidance), you will need to make an application for the electrical work only

Please note: Garden Rooms are not exempt Building Regulation approval

N.B. You should also establish if you need Planning Permission before you start on any exempt building work-You can establish this by contacting our Development Control section
