Planning Permission

If you are replacing existing windows or doors of a domestic house, planning permission is not usually required. You are allowed to change styles and colours. Exceptions include listed buildings and houses located in conservation areas. Special consent is required for these.

If in doubt, contact Aluminium Windows Ltd for free advice. Information about planning and building regulations can be found at:

There are other sorts of restrictions such as the usual insistence that windows in flats need to be approved by the management committee and normally must not alter in design. Replacement installations must comply with building regulations (see above link). This requirement is satisfied by AWL issuing a CERTASS certificate.

If you are having windows or doors installed in a new building or new extension, planning permission will be included in the original planning approval. In this case there is no need for AWL to issue a CERTASS certificate.

In the case of orangeries it is best to contact AWL for advice about planning permission. The following notes provide useful guidelines;

  • Orangeries must not exceed or cover in excess of 50% of the size of the house.
  • Your orangery must not exceed 4 meters (400 cm) in height.
  • Verandas, balconies or elevated platforms must not be included in the orangery design.
  • Should be no more than half the width of your current property.
  • The eaves should be no higher than 3 metres if within 2 metres of a structure boundary.

It is recommended that a division between the host building and the orangery which constitutes a separation, in the form of a door is installed. A walk-through such as an archway from the host building to the orangery is against Building Regulations.

Do I Need Planning Permission?

If the answer to any of these questions is yes then you may be required to seek planning permission;

1. Will any part of the proposed orangery be visible from a road or other public right of way (normally within 20M including footpaths)?

2. Have there been any previous extensions/additions to the original property?

3. Is the property a listed building?

4. Is the property in a conservation area or an area of outstanding natural beauty?

5. Are there any known restrictions or covenants regarding development on the property, such as a leasehold, housing association or joint ownership?

Not keeping in line with planning permission regulations can result in a large fine, as well as the possibility of taking down your orangery and facing prosecution. Avoid all of this by choosing Aluminium Window Ltd.
