Can I upgrade my windows and doors to reduce heat loss?

Inefficient windows and doors can significantly contribute to heat loss. Replacing single glazed windows by installing double glazing can cut heat loss through windows considerably. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.  

If you can't replace all the windows, why not choose the rooms that cost you the most to heat? Other options to reduce heat loss through windows include sealing gaps or using thermal blinds.

You don’t usually need planning permission for repairs, maintenance and minor improvements or replacing windows and doors that are of a similar appearance.

Building regulations apply to replacement glazing, in terms of thermal performance, air supply, ventilation, safety and means of escape.

Common Questions

Do I need planning permission to run an Airbnb or bed and breakfast?

Planning permission is not required if the home will be used as a short-term let for 90 days or less throughout the year.

If you plan on using the home as a short-term let for more than this time period, then you will need to apply for planning permission for a change of use.

If you rent a room in your property while you still live there, you will not require planning permission.

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 new external steps outside my house need planning permission or building control approval?

Planning permission is not normally required for steps in a garden, however, permission may be required if the steps are part of a larger project such as a raised deck attached to the front of the house.

If the external steps are attached to the house and a roof is constructed, this will become a porch which has different rules attached. Read full details on the planning rules for porches in our common projects section.

Different rules may apply if you live in a designated area such as a conservation area or if the building you live in is listed.

External steps will not normally require building regulations approval unless they are part of the access to the building. If they are then you must ensure that you do not reduce the level of accessibility to the house.

You should contact your local planning authority for further project advice, alternatively, you can apply for a lawful development certificate for confirmation that any changes you make do not require planning permission.

What are the planning and building rules to add a concrete slope in my front garden for wheelchair access?

Adding a permanent wheelchair ramp for access to a home is likely to require planning permission as it will permanently change the external appearance of the front of the house. If the application is solely for improving disable access to the building then the planning application will be exempt from a planning fee.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

All permanent wheelchair ramps must comply with Approved Document M of the building regulations which specifies the gradient, width and surfaces which should be used.

Read Approved Document M: Access to and use of buildings.

I want to widen an external and an internal doorway to fit a wheelchair, do I need planning permission and building regulations approval?

Widening or creating a new external doorway will likely fall under permitted development rights, meaning an application for planning permission is not required provided you meet limits and conditions set out in legislation. If the change is on the side or rear of the building it is more likely to comply with planning regulations.

If you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.

New external doorways which create a new or widened opening must comply with building regulations as they may impact the structure of a building.
