What is a ‘P certificate’ and how do I get one?

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.

Common Questions

Do I need planning or building control for covered outdoor kitchen?

If an outdoor kitchen is not a permanent structure, then planning permission will normally not be required.

Where planning permission is required, it may be granted through permitted development rights, provided it meets the limits set out in legislation. Most outdoor kitchens fall within the set limits unless they are particularly tall or close to a boundary.

While there is no specific permitted development right for ‘outdoor kitchens’ it may be classified as an ‘outbuilding’.

You can view the limitations for outbuildings and outdoor kitchens in the relevant common project

If the structure exceeds the limits set out through permitted development rights, then it will require an application for planning permission.

Different rules may apply if you live in a listed building or conservation area. If this is the case, you may wish to consult your local planning authority.

Read about the building regulations that cover outdoor kitchens.

Do I need planning permission to change use of commercial property to residential?

Changing from a commercial use (use class E) to residential(use class C3) falls under permitted development rights, meaning an application for planning permission is not required.

To use the permitted development right you must meet the rules and regulations set out in legislation, this includes submitting an application for prior approval to the local planning authority. The full list of conditions is available on the government website, or our online application form will tell you whether you are eligible.

If you are not eligible for the permitted development right, you will have to submit an application for full planning permission.

Do I need planning permission to replace an existing bay window?

Replacing the window within a bay window is treated the same as any other window. Meaning that the replacement of windows which have a similar appearance to those previously used would not require an application for planning permission.

Repairs, maintenance and minor improvements will also not require an application.

If you live in a listed building or a designated area then different rules may apply.

For more details on replacing windows, visit our common projects section.

Do I need planning permission to extend my front porch to add a downstairs toilet?

It is likely that you will require planning permission to extend an existing front porch to add a toilet.

Adding a porch falls within permitted development rights meaning an application for planning permission is not required provided specified limits and conditions are met. However, to fall under permitted development rights for a porch, the total ground area must not exceed three square metres. This is unlikely to be enough room to fit toilet and the required additional components.

Read the full rules for porches under permitted development on our mini guides.

 

If your porch exceeds these limits, it will be classified as an extension. These can be permitted development but come with a different set of rules.

Extensions are not permitted development if they are built forward of the ‘principal elevation’ of the house. As such, you will be required to submit an application for planning permission to your local planning authority.

If you live in a listed building, you will need listed building consent for any significant changes.
