I’m having a conservatory on my property do I need planning permission?

As a general rule planning permission is not required for a conservatory, although there are a few exceptions to this rule, and they are:

  • no more than half the area of land around your property would be covered by additions or other buildings. This calculation is based on your original property.  So if you have already have an existing extension you’ll need to take that into consideration.
  • Your conservatory, or extension, cannot extend forward of your existing property – both at the front or the side.
  • If you are having an extension, it can’t be higher than your existing roof.
  • The maximum height of a conservatory or single storey extension is four metres.

Do I need Building Regulations and Planning Permission?

Every installation is different, while you might not need Planning Permission, you might need Building Regulations.  While Planning Permission governs the look and aesthetic impact of your property, Building Regulations are in place to check that the work being carried out is safe and energy efficient but it also includes structural and electrical safety, effective ventilation and drainage to name but a few.

Some conservatory designs are exempt from Building Regulations but if you’re planning to remove an exterior wall and make the plan ‘open space’ then you’ll need Building Regulations consent.  If however, you’re planning to keep the new space separate from the existing house, you’re planning to use a separate heating source then Building Regulations will not be required.

Do I need Building Regulations or Planning Permission for my new windows and doors?

If your new doors and windows are similar to the ones you are replacing then you won’t need Planning Permission – but if you’re having a new bay built, you might need Planning Permission for that, you’ll need to check with your local Planning office.  New windows and doors are, however, governed by Building Regulations which ensure that your replacement windows and doors are safe, provide sufficient air supply, appropriate means of escape and ventilation.

A CIN installer will be approved to carry out the work to comply with building regulations without involving your local authority building control – once the work is completed they will send you a certificate showing the work has been done by a registered installer.
