Do you need planning permission for a conservatory?

If you’re considering adding a conservatory to your home, you’ll be pleased to know that in most cases, planning permission is not needed. Don’t breathe a sigh of relief too soon, however. There are certain conditions that would mean the addition is not allowed under ‘permitted development’ rules.

How Big Can You Build a Conservatory Without Planning Permission?

In 2019, the Government amended the rules regarding conservatory development. The changes were brought into effect to help provide flexibility for growing families that didn’t want to move. The change in the law states that:

  • Those in semi-detached and terraced houses can make extensions (including conservatories) to their home up to 6 metres, without planning permission.
  • Those with detached houses can add extensions (including conservatories) up to 8 metres without planning permission.

Under the Neighbour Consultation Scheme, neighbours will be notified of your development, even if it is permitted by law, and will have the opportunity to raise any objections.

How close can you build a conservatory to a boundary?

The proximity you can build a conservatory to a boundary will depend on its size. If the conservatory is under 3 metres in height, you can build right up to the boundary. Different rules apply for extensions of more than one storey.

Do I Need Planning Permission to Change my Conservatory Roof?

In most cases, you can change your conservatory roof without obtaining planning permission. If you amend the structure of your conservatory, you must make sure that all building regulations checks are carried out by a professional. Failure to do so could leave you with an unsound structure and the danger of your roof collapsing. When changing the roof of your conservatory, remember to observe the following:

  • The roof of the conservatory must not be taller than the highest part of your existing house
  • The conservatory should be separated from the rest of your home with exterior standard doors (if you want your home to flow through to your conservatory, without the separation of doors, then a full building regulation application will be required.)

Remember, if you live in a listed building or conservation area other regulations may apply, so you must check with your local authority.

Do You Need Building Regulations Checks For a Conservatory? 

Building regulations are separate from planning permission. Whilst planning permission may be required for changes to your home that affect the space around it (and potentially your neighbours) building regulations make sure a building or home is safe and built to a certain standard.

Conservatories have been exempt from building regulations since the mid-’80s. As noted above, however, if the structure of your conservatory changes, building regulations may apply.

Do I need planning permission for a conservatory with a radiator? 

In short, no. Conservatories need to be a usable space in your home all year round, so including a radiator in them does not require any extra planning permission. In addition to this, if you opt for a radiator that is separated from your home’s central heating system, it will be exempt from standard heat loss regulations. An integrated central heating system in your conservatory will need to meet heating efficiency building regulations.
