Adding a porch canopy is classed as permitted development provided it meets the limits and conditions set out in legislation. Where this is the case, no application for planning permission is required.

Porches must meet the following limits:

• the ground floor area (measured externally) would not exceed three square metres.
• no part would be more than three metres aboveground level (height needs to be measured in the same way as for a house extension).
• no part of the porch would be within two metres of any boundary of the dwellinghouse and the highway.

Read our mini guide for additional information on installing a porch.

An improvement notice is a notice served by a local authority requiring a property owner to carry out specified works to bring a building into compliance with the legal standards. These are most commonly served to landlords to make a building safe.

The notice will specify what works should be completed and when it should begin and be completed by.

Failure to comply with an improvement notice is a criminal offence.

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.

Significant changes to insulation and thermal elements would normally require building regulations approval. The extent to which this applies depends on the existing insulation and what it will be replaced with.

If the work is completed by a member of a competent persons scheme, then an application for approval will not be required.
