Planning permission is unlikely to be required for the installation of external damp proofing unless the work will change the external appearance of the building or is part of a larger project.
If you live in a listed building you will need listed building consent for any significant changes, this can include external damp proofing. Additional rules may also apply if you live in a Conservation Area or other protected area.
Building regulations approval is not required for installing an external damp proof course (DPC).
Work to refit a bathroom with new units and fittings does not generally require building regulations approval, although drainage or electrical works that form part of the refit may require approval under the building regulations.
If a bathroom is to be provided in a room where there wasn't one before, building regulations approval is likely to be required to ensure that the room will have adequate ventilation and drainage, and meet requirements with respect to structural stability, electrical and fire safety.
If you do not seek planning permission, build without it when it applies, or do not meet specified conditions of a planning permission, this is known as a planning breach.
Your local planning authority can serve an enforcement notice on you when they consider you have broken planning rules. You may be given the opportunity to apply retrospectively, or be required to remove a building or structure, or alter it to make it acceptable.
A ‘P certificate’ may refer to confirmation that electrical installations within a building are compliant with Approved Document P of the building regulations.
An electrician who is Part P certified is able to self-certify domestic work they complete, meaning you do not have to submit a building notice. To ensure your electrician is Part P certified, use a registered competent person.
If your proposal for planning permission or building regulations approval is solely for extensions or alterations to a disabled person’s house to improve access, safety or comfort then you are exempt from paying a planning or building control fee. Additionally, if you are providing means of access for disabled persons to public buildings you are exempt from any fee.
Note that for building regulations approval, you will only be exempt when applying to a local authority building control body.
Planning permission is not required to remove an internal chimney breast as the change does not impact the exterior of the house. Rules may differ if you are planning on removing the chimney stack, or if you are in a conservation area.
If you live in a listed building, then you will need to apply for listed building consent for any major changes to the building.
Building regulations approval will always apply when removing chimney breasts as they are part of the building’s structure. You should seek advice from a structural engineer who will provide drawings and calculations that can be submitted as part of your application.
