uPVC conservatories planning permission


England and Wales

For homeowners in England and Wales planning permission is not normally required unless permitted development is exceeded. This permitted development has been extended by the Government to help people create larger uPVC conservatories.

Depending on the area you live, the usual permitted development before any changes was 50-70 cubic metres. Be aware though that exceptions to this would include listed buildings or properties in a Conservation Area.

Also, if your property has been previously extended then part of the permitted development would have been used. Permitted development may also be withdrawn from a property, so always double check with your local council or planning officer.

Building Regulations for uPVC conservatories

Building regulations are a different kettle of fish entirely and it’s important to be aware of the rules. Remember, reputable contractors will have sufficient knowledge of Building Regulations so it’s always recommended to ensure using Quotatis to compare quotes.

Essentially, the basic principles of Building Regulations for uPVC conservatories are listed below:

  • The uPVC conservatories must have a transparent or translucent roof
  • No more than 25% of the installation should be brickwork
  • The floor area should not be larger than 30m squared
  • The conservatory is positioned on the ground level of your property
  • A door separated the conservatory from the rest of your home
  • Any heating such as radiators is controllable
  • Glazing installed meets regulations of part N, Schedule 1 (toughened/safety)
  • There are not any drainage facilities such as a toilet or sink

Where Building Regulations have to be separately applied for, common circumstances are if the extension will be a kitchen or bathroom. Contacting the local council is your first port of call to get specific advice on your intentions.

A final point to consider is that if you require Building Regulations approval then the glazing installed will need to meet the highest insulation qualities (namely Pilkington K Glass with Argon filled gas spacers).
