Remaining one of the most treasured UK home improvements, planning your conservatory or orangery upgrade or installation should be an enjoyable and rewarding experience for the whole family. However, the initial process can become quite baffling for renovators who don’t have the support of a local expert to answer the plethora of questions that this type of installation can bring. With this in mind, we thought we’d start at the very beginning and address the most commonly asked question on conservatory installations across Oxfordshire and Suffolk;

Do I need planning permission for a conservatory?

Generally, the quick answer to whether planning permission is needed for a conservatory is no as conservatory development is normally categorised under ‘permitted development rights’.

What is ‘permitted development’?

Permitted development rights cover common home improvements & extensions (for houses), that can be carried out without the need to apply for planning permission. However, there are certain limits and conditions that must be followed to comply with permitted development rights. These are:

  • No more than half the land around the original house can be occupied by the conservatory.
  • Conservatories on the front or side of a house cannot be situated closer to a public highway than the original property.
  • The conservatory roof, eaves and ridges cannot exceed the height of the original building.
  • Attached house conservatories must not extend beyond the rear wall of the original property by more than 3 metres, whereas detached house conservatories must not extend beyond the rear wall of the original property by more than 4 metres.

For more information, contact one of our experts who can provide information specific to your property and requests.

Further information on conservatory planning permissions:

Subject to the neighbour consultation scheme, outside Article 1(5) designated land (e.g. national parks, the Broads, Areas of Outstanding Natural Beauty (AONB)* conservation areas and World Heritage sites) & Sites of Special Scientific Interest, the rear wall extension limit is increased to 6m for attached houses and 8m for detached houses as long as it’s completed by 30th May 2019.

  • Rear single-storey conservatory structures must not exceed 4m in height.
  • Conservatories with more than one storey must not exceed the rear wall of the original building by more than 3m or be within 7m of any boundary opposite the rear wall of the house.
  • Conservatory eaves must not exceed 2m in height of the boundary of 3m.
  • Single storey side conservatories cannot exceed 4m in height and the width should be no more than half of the original house.
  • Conservatory roof pitches higher than one storey must match the existing house.
  • Verandas, balconies or raised platforms do not qualify for permitted development.
  • On designated land *(see above) rear conservatories with more than one storey, exterior cladding or side conservatories do not qualify for permitted development.
  • These restrictions only apply to houses in England, not to flats or maisonettes.

So, if your conservatory project includes any of the restraints listed above or falls within an Article 4 area you may need to seek conservatory planning permission from your local authority.
