Do I need planning permission or building control approval to raise the height of an external doorway?
Whether raising the height of an external door requires planning permission depends on the location of the door, location of the property and how drastic the height change will be.
For smaller changes to the side and rear of the property, permitted development rights may apply, meaning no application or planning permission is required.
Where the height change will be substantial and have a significant impact on the building’s appearance, planning permission is likely to be required. Especially in cases where the door to be heightened is on the principal elevation of the property.
Principle elevation - The most visible or prominent side of a structure, typically facing a street or public area. While often considered the 'front' of the building, it may not always contain the main entrance.
In designated areas such as conservation areas, or on listed buildings you may require additional approvals such as listed building consent.
If you believe permitted development rights apply to a small change, you can apply for a lawful development certificate to ensure this is the case.
Building regulations
Building regulations approval will likely be required where the change impacts the structure of a building, this primarily occurs when an opening is widened. When altering walls you may want to consult a structural engineer.
Common Questions
You likely will require advertisement consent to display a commercial advertisement outside your home, especially when the company does not operate from that location.
It is more likely that permission will be required where:
- the sign is over 0.3 square metres or illuminated
- the sign is visible from a road
- the building is listed or in a designated area then consent

Most garden ponds will fall under permitted development rights, meaning an application for planning permission is not required. In planning terms a pond will be classed as an outbuilding, to read the full rules around installing an outbuilding, visit our common projects section.
For ponds which are particularly deep or large, you may need to apply for planning permission. If you are unsure, you should contact your local planning authority for advice.
In a listed building you will require listed building consent for any major changes.
When installing a pond, you should take into account other regulatory considerations such as environmental permits or any protected species which may be impacted. Further thought will have to be placed when creating ponds near riverways or in areas of flood risk.
A single storey rear extension can fall under permitted development, meaning planning permission may not be required providing it meets certain criteria.
In terms of height, the extension must:
- Be no taller than four metres at its highest point
- Have eaves no higher than the eaves of the original house
- Not exceed the height of the original dwelling

Installing solar panels on your roof will often fall under permitted development rights, meaning an application for planning permission is not required provided certain limits and conditions are met.
The limits and conditions vary based on the type of roof you want to install the solar panels on and the location of the house. See the details below:
· On a pitched roof, panels should not be installed above the highest part of the roof (excluding the chimney) and should project no more than 200mm from the roof slope or wall surface.
· On a flat roof the highest part of the solar PV equipment cannot be more than 600mm higher than the highest part of the roof(excluding chimney).
· The panels must not be installed on a building that is within the grounds of a listed building or on a site designated as a scheduled monument.
· If your property is in a conservation area, or in a World Heritage Site, panels must not be fitted to a wall which fronts a highway.
As you have stated you’re in a conservation area, you must apply to the local authority for prior approval. This process includes submitting a form to the local planning authority which ensures that you meet the limits set out in legislation.
Forms relating to prior approval for mounting solar equipment can be submitted through the Planning Portal’s online application service and attract a fee of £240.

By law, any planning permission granted expires after a certain period. Generally, unless your permission says otherwise, you have three years from the date it's granted to begin the development. If you haven't started work by then, you will probably need to reapply.
