Do I need planning permission or building control approval to merge two flats into one?
Merging two flats into one, commonly known as amalgamation is likely to require planning permission as it will impact the local planning authorities housing supply. The council’s views on this will vary from council to council. It is recommended that you contact your local planning authority to understand their position.
If you do not need to apply for planning permission then you can apply for a lawful development certificate to prove that the change is lawful.
Building regulations will be required if there are physical works taking place as part of the amalgamation, this may include removing walls or changing electrics. Visit the relevant common projects on our site for more information.

A dropped kerb is a sloping point in the pavement to provide access by vehicle to a property. Dropped kerbs aren’t usually a planning matter although it is recommended that you contact your local authority to find out if planning permission is required, and you will need to make a specific dropped kerb application for a domestic vehicle crossing licence to your local authority.
Work to create a dropped kerb must be carried out by a New Roads and Street Works Act accredited contractor.
Yes, but this type of conversion will require full planning permission. This is because you’d be changing the use of the ground floor from residential to commercial (typically to a use class such as E), while the upper floor would remain as a residential flat (Class C3). The change of use triggers the need for planning approval.

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.
