Do I need planning permission questions: what is permitted development?
Permitted Development is external building work or changes of use that can be undertaken without planning permission. The Government has set restrictions on what can be built including the size/height/depth, or which uses may be changed. This is known as the General Permitted Development Order. The Council cannot confirm verbally that your works or change of use would be Permitted Development. If you want confirmation from the Council you would need to apply for a Certificate of Lawfulness for a proposed or existing use or works, demonstrating that the work or change of use is “permitted” and therefore not requiring planning permission, and that it complies with any conditions attached to the permitted development rights.
Do I need planning permission to carry out works to my flat?
Planning permission is always required when carrying out external alteration works to a flat as flats do not have permitted development rights. You should also seek permission of the freeholder for any works.
Do I need planning permission for a Green House / Shed in my Garden?
You need to find out if the property is a single family dwelling or flats. If flats they will need to apply for Planning Permission, if it’s a single family dwelling it could fall within Permitted Development Rights, please refer to Planning Portal for limits and conditions regarding height, location and size.
Do I need Planning permission for a Loft Conversion/Roof extension/Dormer roof extension?
Planning permission is not normally required for a loft conversion that only involves internal works to create a space within the existing roof. Permission is sometimes required where you extend the roof (by building a roof extension or dormer) or alter the roof space and it exceeds specified limits and conditions. Roof extensions are in some instances permitted development for houses, subject to limits and conditions which you can find on the Planning Portal. You will always require permission for external extensions to a roof in a conservation area, or if the property is divided into flats, or if the roof slope fronts a road.
Installation of roof lights are sometimes permitted development, depending on location and height of projection above the roof slope.
Do I need planning permission to install a satellite dish?
Depends whether the property is in a conservation area or listed building, depends on how high the building is and how many satellite dishes are already on the building. Please refer to the Interactive House on the Planning Portal.
Do I need Planning Permission to install solar panels?
In many cases fixing solar panels to the roof of a single family dwelling is likely to be considered 'permitted development' with no need to apply for planning permission. There are however, important exceptions and conditions which must be observed. These permitted development rights apply to houses. If you live in a flat and are considering fitting solar panels please visit the Planning Portal for further updates.
Do I need planning permission for my boiler flue?
On a house outside of a conservation area and not on a listed building it’s likely to be permitted development. On a house inside of a conservation area and the flue is not visible from the highway it’s likely to be permitted development. *For both if the customer wants confirmation they need to apply for certificate of lawfulness. If on a flat and visible, it is likely to require planning permission dependent on the circumstances. Listed building consent will most likely be necessary if the building is Listed, even if planning permission may not be required.
Do I need planning permission if I want to change my windows?
If the property is a flat planning permission will be required in the following cases:
- it will be installed where there was not one before;
- it will be made of a different material to the existing (for instance replacing a timber window with a uPVC window);
- it will be of a different size to the existing; or
- it will differ in appearance to the existing (for instance replacing a sash window with a casement window or altering the glazing bar pattern).
If the property is a listed building, listed building consent is required and will probably only be granted if the windows are beyond repair and like for like work is carried out.
If in a conservation area it is likely that permission is required if the windows are on a front or street facing elevation. If the existing window is single glazed most proposals for double-glazing unavoidably constitute a material change in appearance and in these cases permission will be required.
What is a crossover and do I need planning permission?
A cross over is a dip in the kerb to go into a driveway.
In certain circumstances (if you live on a trunk road or a classified road) you may need to apply for planning permission as well as apply for permission from the Highways team. In conservation areas planning permission may also be required, especially if works involve the removal or alteration of a gate wall or fence.
