Replacement Windows – Do You Need Planning Permission?
There are a number of reasons why you may choose to replace the windows in your property: for a fresher look, as part of a renovating project, to make your home more energy efficient or to improve your home security. However, depending on the planning constraints of your property, you may or may not need planning permission for subsequent replacements.
Hereís a brief guide for what you need to know.
No Permission Needed
Most houses wonít need planning permission for replacement windows as they are covered under a propertyís Permitted Development Rights. Permitted changes include minor repairs, general maintenance and repainting.
However, there are certain conditions youíll have to comply with:
- Replacements must be of a similar appearance to the original windows youíre replacing. For example, if you want to install a new bay window, it will be considered an extension and you may need permission.
- Upper floor windows inserted into the side walls must be obscure-glazed and non-opening if they are less than 1.7 metres above floor level.
Skylights donít usually need special permission as long as they donít protrude more than 150 mm out from the slope of the roof and they are not higher than the highest point of the roof.
Planning permission to replace windows will be needed if your council withdraws Permitted Development Rights under the Article 4 Direction, an act applied by the local planning authority to conservation areas under their jurisdiction. Listed buildings will need both planning permission and Listed Building Consent.
However, itís not just a case of obtaining permission then doing what you want. You must also fulfil the following requirements:
- To preserve the original character, replacement windows must replicate the original ones. This includes openings, fixtures and authentic detailing to ensure the special interest of the building is maintained.
- In order to comply with thermal insulation standards, replacement windows will usually need to be double glazed.
- Replacement windows must match those of neighbouring properties such as terraced houses. A house thatís being converted into multiple flats must have identically styled windows throughout the property.
- All windows must be equipped with safety standard, unobtrusive security locks.
Brighton and Hove Council have strict regulations for replacing windows in certain areas. If youíre not sure whether you need permission or not, always check before starting any building works.
