Planning permission is not required for internal changes such as changing a bathroom to an accessible wetroom, however, if you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

Building regulations approval will likely be required for changes to a make a bathroom accessible, specifically when the change will impact the structure of the room, drainage and electrical systems. It is recommended to have work completed by a member of the competent person scheme.

The addition of a new external doorway will often fall under permitted development rights, meaning an application for planning permission is not required. This applies where the new doors are of similar appearance to those used elsewhere on the original building.

Permission may be required if your property is listed, you live in a conservation area oran Article 4 direction is in place. In these circumstances it is best to contact your local planning authority for more advice.

New external doorways which create a new or widened opening must comply with building regulations. A new structural opening will require a building regulations application.

The installation of a new door can be completed by a 'competent person' to ensure building regulation requirements are met. For more information on the competent person scheme and to find a registered person, visit the GOV.uk website.

Building a porch at ground level and under 30 square metres in floor area is normally exempt from the need for building regulations approval.

This is provided that glazing and any fixed electrical installations comply with the appropriate sections of building regulations.

Categorising land and buildings according to their type and purpose is known as Use Classes.

A 'Change of use' can be within the same Use Class or from one Use Class to another.

You will need planning permission for certain changes to the use of a property such as changing from a residential use to a business use. However, it is possible to change use between some classes without having to make an application for planning permission.

Depending on the specifics of any proposed change of use, including any building work associated with the proposal, an application for planning permission or prior approval may be required.

A garden gazebo or freestanding awning will often fall under permitted development rights provided it abides by the restrictions set out by government. In this instance a garden gazebo or freestanding awning will be classed as an outbuilding and should not be in front of the house or more than 2.5 metres in height.

Different rules apply if the awning is attached to the house itself. It may still be permitted development, but falls under the class of enlargement, improvement or alteration.
