Your planning application must be made up of:

• The necessary plans of the site
• The required supporting documentation
• The completed form
• The correct fee.

The local planning authority will not be able to process your application unless the mandatory supporting documentation has been provided. You can also attach any other relevant documentation which you think will help the local authority determine the application.

What supporting documentation must be provided depends on the application type,  development type and local planning authority.

There are two levels of mandatory documents, national and local. If you’re applying online, the service will tell you what mandatory documentation you need to provide and allows you to attach the relevant documents. Most applications will require you to provide a location plan and a site plan.

In addition to the national list, your LPA may produce a list which details any specific documentation that is required to accompany the application. The requirements may vary according to the type of application, i.e. household, full, outline, etc. If you are applying online, this list is available from the supporting documents screen or your local planning authority’s website.

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.

Work that requires building control approval will require a completion notice to be submitted to the building control body. The completion notice must be sent within five days of the work being completed, once submitted, the building control body can visit the site to complete a final inspection.

If the work meets the required standards they will issue a completion certificate.

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.

Planning permission is not required for the installation of a stair lift, 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.

Stairlifts must be installed in line with BS EN 81-40:2020 which focuses on safety requirements for the installation of stairlifts.
