Common business projects
(Changes of use, installation of canopies and awnings, alteration of shopfronts, installation of advertisements and CCTVs.)
- a) Do I need permission to change or replace windows?
You will need planning permission to change windows or doors in your property if the replacement windows do not match the original windows.
The materials used in any exterior work must be of a similar appearance.
If the materials used and/or the method of opening are not similar to the original windows then planning permission would be required.
- b) Do I need permission to install satellite dishes?
You need planning permission to put up a satellite dish in a flat or any other premise.
It might be possible to put up a satellite dish without the need for planning permission in a house, under permitted development rights.
You can apply for a Certificate of Lawful Development to get confirmation that the proposed works fall under permitted development rights.
- c) Do I need permission to create a roof terrace?
Yes. You will need to apply for planning permission to create a roof terrace for a flat or a house.
- d) Do I need permission to erect a garden shed and/or an outbuilding?
You will need to apply for planning permission to erect a garden shed or an outbuilding for a flat.
For a house, the erection of a garden shed or an outbuilding can be permitted development if it complies with the rules.
If the property is in a Conservation Area, you will need planning permission if the proposed outbuilding will be at the side or front of the property.
- e) Do I need permission to make a basement or roof extension?
If your property is a flat or maisonette, you will require planning permission to make a basement or roof extension. This includes loft extension and the installation of lightwells.
Following an Article 4 direction in April 2018, you now need full planning permission to create or extend the basement.
To check our current planning regarding basements and roof extensions, please see pages 187 to 190 of the Local Plan (pdf). See also pages 64 to 69 of the Planning Guidance - Supplementary Planning Document (SPD) (pdf)

Planning permission is not required for a person to short term let/holiday let a property or a room within their property as long as:
- they are the person who is liable to pay council tax for the property;
- they don't let the property on short term lets for more than a total of 90 days in any calendar year.
These new provisions do not apply to companies or letting agencies.
This council has a zero tolerance approach to those who are flouting the regulations and will take enforcement action against owners or landlords who are found to be in breach of the regulations.
- g) Do I need permission to install a solar panel?
It is generally possible for single houses or a building of flats to install solar panels without planning permission. However, the location of the solar panel should be such as to minimize the effect on amenities or the visual of the area.
You can make an application for a Certificate of Lawful Development to obtain confirmation that the proposed works fall under permitted development rights.
- h) Do I need permission to change or replace boundaries, fences and railings?
You don’t need planning permission if your proposal is to take down a fence, wall or gate, or to alter, maintain or improve an existing fence, wall or gate (no matter how high) if you don't increase its height.
If you want to erect a new boundary wall, fence, railings or gate that exceeds one metre high and it is next to a highway used by vehicles (or the footpath of such a highway); or over two metres high elsewhere you will need planning permission.
- i) Do I need permission to install flues, pipes and chimneys?
You will need planning permission to install flues, pipes and chimneys in a flat.
A proposal to install flues, pipes and chimneys in a house might be Permitted Development if the proposal is not 1m higher than the highest part of the roof.
If the house is covered by an Article 4 or is located in a Conservation Area, and the proposal affects the side or front elevation of the house, it is likely that you will require planning permission.
- j) Do I need permission to create a hardstanding on my front garden?
In the case of a flat, you will need to apply for a full planning permission to create a hardstanding surface. In the case of a house, you will require to apply for a householder application if the proposal exceeds 5m2; the hard surface will be made of non-porous materials; no provision will be made to direct run-off water to a permeable or porous area within the land around the original house.
- k) Do I need permission to prune or remove trees from my property?
Generally you don’t need planning permission to prune or remove a tree unless it is in a conservation area; in which case you will need to give us six weeks notice about the proposed works to the tree.
Some trees are protected and you’ll need planning permission to prune or remove them. These are known as Tree Preservation Orders (TPO) and you can find more information through our Urban Design and Conservation team.
