Do you require planning permission for a conservatory?


When we start to think about having a conservatory fitted to our home, one of the considerations that many people forget is: Do you require planning permission for a conservatory?

Planning Permission

Generally to erect a conservatory you will not need to get planning permission. However, there are a number of exceptions that will require your consideration before you start to undertake any building work.
Standard conservatories will be exempt from planning permission as long as they fall within the parameters:

  • They are built at ground level and are less than 30 square metres in floor area.
  • The conservatory is separated from the house by external quality walls, doors or windows.
  • There should be an independent heating system with separate temperature and on/off controls.
  • Glazing and any fixed electrical installations comply with the applicable building regulations requirements

When do I need planning permission?

There are a number of factors that mean that you will need to obtain planning permission for your conservatory. These can include:

  • Your planned conservatory will cover more than 50% of the land that surrounds the original house (including and existing building or extensions)
  • Your planned conservatory is to the front or side of the house that faces onto a road (regardless of hedgerow and fencing)
  • Your planned conservatory roof peaks higher than the highest point of the original roof, such as a conservatory attached to a bungalow with a high pitched roof.
  • The planned eaves and ridge height are above that of the existing building, as above this is such as a bungalow.
  • The planned eaves height is more than 3 meters, this applies when the new conservatory will be within 2 meters of the boundary.

Other considerations will need to be made depending on the location of your planned conservatory:

  • Conservatories built to the side: planning permission is required if they are wider than half the width of the original house or is more than a single storey or 4-meters tall.
  • Conservatories built to the rear: planning permission is required where the conservatory extends beyond the rear of the house by 6 meters (for a semi-detached) or 8 meters (for a detached), or is more than 4 meters in height.

If you are ever in doubt about planning permission, or if you are unsure of policies within your local area, we recommend contacting your local authorities before you undertake any work. It is easier to alter plans or get planning permissions before any work begins.
