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.

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.

Demolishing a building may require planning permission or prior approval, depending on factors such as the building’s type, size, and location.

Before starting any demolition work, it’s important to consult your local planning authority to confirm what permissions are needed. This helps avoid the risk of enforcement action or legal consequences.

You will also need to ensure you conform to the building regulations around the demolishing of a building.

Following a grant of planning permission, it may be necessary to make amendments to the proposals that were originally approved. A non-material amendment may be applied for to approve a minor change to the planning permission which does not breach any conditions originally placed on the consent.

There is no statutory definition for ‘non-material’ as it can vary on a case-by-case basis. In general, if the change will increase the size, change the appearance of a development or have a large impact on other considerations then it will not be considered non-material.
