Do I need permission to remove chimney stack on a property in a conservation area?

Removing a chimney stack may fall under permitted development rights, meaning no application for planning permission is required provided certain limits and conditions are met.

The permitted development right which covers this focuses on the installation, alteration or replacement of a chimney, note that this does not specifically mention removal. Rules in a conservation area may differ, in this instance you should contact your local planning authority directly to understand their position, and if the building is listed, then you will need listed building consent.

To ensure that the local planning authority will allow the removal of the chimney stack you can apply for a lawful development certificate. If approved, then no enforcement action can be taken against the change.

If the chimney is shared (i.e. as part of a terrace), you might need to discuss with relevant neighbour and obtain a party wall agreement.

Building regulations approval may not be required if you are removing the external chimney stack above the roof. If works progress to the internal chimney stack or breasts, then it will require building regulations to understand the structural impact.

Common Questions

Can I install patio doors to the rear of my house where there is currently a single external door?

Installing patio doors at the rear of your house is likely to fall under permitted development rights, meaning an application for planning permission is not required, provided certain limits and conditions are met.

The doors should be of similar appearance to those previously used, if they are not then generally planning permission will be required.

If you live in a listed building, you will need listed building consent for any significant works.
If you live in a designated area such as a conservation area or national park, then additional restrictions may be in place.

If you are unsure whether the work falls within permitted development rights you can check with your local planning authority or submit a lawful development certificate to prove the change is lawful and prevent any future enforcement action.

What is permitted development?

Permitted development rights allow certain types of work to be carried out without the need to apply for planning permission. It typically covers things like small extensions, loft conversions and outbuildings, provided they meet specific size and location limits. These rights can vary or be removed in areas like conservation zones and by Article 4’s, so it’s best to check before proceeding.

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.

How much does a planning application cost?

There are different planning fees for England and Wales, and many different application types depending on the work being carried out.

You can use the Planning Portal's fee calculator to work out fees for different kinds of proposal.

Use the fee calculator (England)

Use the fee calculator (Wales)

 

While every effort has been taken to ensure that the fee has been calculated correctly, the determination of whether a planning fee is correct is the responsibility of the relevant local planning authority, who will check the fee is correct when the application is submitted and validated.

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.
