Whether or not your building project needs planning permission you will still need to meet building regulations. See Bristol City Council’s website (below right)
- There is less detail on solid wall insulation for which planning permission is not normally required for fitting as long as there is no change in external appearance. However, if the building is listed or is in a conservation area you should consult your local planning authority.
- Some recent changes have been made in the planning requirements for single story rear extensions. See also here.
- In most cases, solar panels on houses do not need planning permission. However there are some restrictions, for example, the panels should not project more than 200mm from the roof or wall.
Listed buildings and conservation areas
- If you are replacing windows, as long as you are retaining like for like materials, finishes and style (i.e. single glazed wood box framed sash windows for double glazed wood box framed sash windows) you will not need planning permission (see exterior and interior pictures above left and right). If you want to change the look and feel of the windows you will need to apply for planning permission.
- If you want to apply external wall insulation and you live in a conservation area you will need to apply for planning permission.
- Solar panels must be installed in line with this guidance:
i) Listed building consent is required if the property is a listed building.
ii) If the property is in a conservation area, planning permission is required if the panels are fitted on the principal or side wall and are visible from the road.
You can find further guidance on solar panels here.
"The windows were rotten, and I’ve known for a number of years that I should do something with them. I found a local manufacturer who was able to make the windows so that they look original. that match what else is in the road." - Michael, 2015 Householder
