Planning and Building Questions

Find out all you need to know about planning permission, the homestyles that we can install in, which includes Listed Buildings and how the All Seasons Roof window installation process will be.

If we haven’t answered all of your questions or if you need more information, give us a call today.

Do I need planning permission for double glazing?

If the aesthetics of your windows remain unchanged it is very unlikely that you will require planning permission to install double glazed windows since it will have no impact on the neighborhood. Before you begin any home improvement project however, it is always best to contact your local authority to find out if you need planning permission.

There are some exceptions:

  • Windows in flats
  • If your house is a listed building
  • If your house is in a conservation area
  • Building under an Article 4 Directive

The All Seasons Roof Elite Sliding Sash is ideal for buildings that fall under Article 4 Directive. Find out more information about the All Seasons Roof Elite Sliding Sash window here.

If you are having a bay window installed in your home considered a building extension and you may therefore have to obtain planning permission before you commence. All Seasons Roof will help you to secure planning permission. We have the expertise to make it happen fast.

Contact us if you have any questions.

Can you install double glazing in a listed building?

The Planning (Listed Buildings and Conservation Areas) Act 1990 governs the treatment of buildings both inside and out.

You must get consent when:

  • You plan to change the style of window
  • The frames will be made from a different material
  • You plan to change the glazing
  • You plan to reglaze the current windows
  • You plan to repaint your current windows in a different colour

Secondary glazing offers many of the advantages of double glazing but requires no planning permission, so if planning permission is required, this is the route that you should take. Call us we’ll help you.

Are you allowed to install double glazing in a conservation area?

The Planning (Listed Buildings and Conservation Areas) Act 1990, covers houses located in a conservation area and planning permission must therefore be obtained before double glazing commences.

If you live in a conservation area it is likely that you will have to install windows that look the same as your existing windows. You local council should be able to advise you on what you will be allowed to do. Once you have spoken to the council, contact us and we keep the council abreast of the planned changes.

See our Conservation Area page for more information on window installations in conservation areas.

Can you install double glazing on stationary caravans?

All of our windows are designed for installation in brick so we cannot install windows in caravans.
