If your proposal for planning permission or building regulations approval is solely for extensions or alterations to a disabled person’s house to improve access, safety or comfort then you are exempt from paying a planning or building control fee. Additionally, if you are providing means of access for disabled persons to public buildings you are exempt from any fee.

Note that for building regulations approval, you will only be exempt when applying to a local authority building control body.

In many circumstances, rules known as ‘permitted development’ rights allow you to extend a house without needing to apply for planning permission, providing specific limitations and conditions are met. If you want to exceed these limits and conditions, then it is likely that an application for householder planning permission will be required.

You can find information about the limits and conditions, prior approval and the building regulations on the Planning Portal by using the links below.

Widening or creating a new external doorway will likely fall under permitted development rights, meaning an application for planning permission is not required provided you meet limits and conditions set out in legislation. If the change is on the side or rear of the building it is more likely to comply with planning regulations.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

New external doorways which create a new or widened opening must comply with building regulations as they may impact the structure of a building.

Many trees are protected by Tree Preservation Orders (TPO) which means that, in general, you need the council's consent to prune or fell them.

A TPO is placed on a tree, group of trees or woodland with the aim of protecting them. The following is prohibited on a protected tree, without the local planning authority's (LPA) consent:

- Felling

- Topping

- Lopping

- Uprooting

- Wilful damage/destruction

Owners of the trees must maintain their trees, and an LPA will often encourage good tree management. However, they are unable to require maintenance work just because a tree falls under a TPO.

If you wish to complete work on a tree under a TPO you will be required to submit an application to the local planning authority. For full details on this application type, read guidance about works to trees and the application process.

Planning permission is not normally required for steps in a garden, however, permission may be required if the steps are part of a larger project such as a raised deck attached to the front of the house.

If the external steps are attached to the house and a roof is constructed, this will become a porch which has different rules attached. Read full details on the planning rules for porches in our common projects section.

Different rules may apply if you live in a designated area such as a conservation area or if the building you live in is listed.

External steps will not normally require building regulations approval unless they are part of the access to the building. If they are then you must ensure that you do not reduce the level of accessibility to the house.

You should contact your local planning authority for further project advice, alternatively, you can apply for a lawful development certificate for confirmation that any changes you make do not require planning permission.
