Do I need planning permisson?
Most conservatories don’t need planning permission. We will of course advise you when we see the site; meanwhile, here is a working guide.
You will need planning permission if:
- the property has had its permitted development rights withdrawn
- the proposed conservatory has any wall facing onto the highway, ie any public thoroughfare including paths and bridleways as well as roads
- the property is a listed building
- the property is in a conservation area
- the property is non-residential
- the property is anything other than a single building – flats and apartments always need planning permission
- the proposed conservatory is higher than any part of the original building
- the proposed conservatory and other additions to the original house exceed 50% of the total area of the garden
- eaves, gutterings, fascias or foundations encroach over the property’s boundaries.
Most conservatories and sun rooms are exempted from Building Regulations. At Trade Windows, we build our conservatories to comply with them in any case, for your complete peace of mind and to meet our high standards.
For your information, though, here’s a useful working guide.

- be sited at ground level
