Conservatories are one of the most desirable ways to extend your home. Offering a beautiful space filled with light, they can transform how you use your home. ‘Do I need planning permission for a conservatory?’; this is a question we’re often asked. Here at Emerald Windows, we’re here to answer all your queries about conservatories and planning permission.

What planning permission do you need for a conservatory?

In most cases, a conservatory is considered permitted development. This means it’s exempt from planning permission as long as it follows certain rules*:

  • The majority of a conservatory needs to be made up of glazing. If you want a solid roof, skylights can be used to break it up
  • The extension must not cover more than half of the land around your home
  • The conservatory cannot be higher than the highest part of your home’s roof
  • A conservatory can’t extend beyond the rear wall of your home by more than 3m if attached or 4m if detached
  • External walls, windows and doors which separate your home and conservatory is another requirement

If you live in a conservation area or listed building, separate rules will apply. Contact your local authority for more information.

Do I need planning permission to replace my conservatory roof?

You don’t normally need planning permission to add a solid roof to an existing structure. However, it does need to comply with Building Regulations. This ensures that the bearing load is sufficient as conservatories aren’t built to cope with tiles. Shortcuts can cause a conservatory collapse. This is especially important to bear in mind if your area is prone to high winds or heavy snow.

Be wary of companies who promise to replace your roof without this affecting your existing structure. Doors and windows often need to be replaced to make sure they can cope with extra weight. Our team will carry out a full survey to assess your conservatory’s structural integrity.

What’s the difference between building regulations approval and planning permission?

Building regulations look at the thermal efficiency and safety of your new conservatory. Planning permission guarantees new structures don’t have a negative effect on your home or your neighbours. It also looks at the impact a development will have on the environment.
