- 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.

If the materials used and/or the method of opening are not similar to the original windows then planning permission would be required.

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.

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.

- 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 in order to obtain confirmation that the proposed works fall under permitted development rights. You can make an application via www.planningportal.gov.uk/apply.

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.
