Conservation areas and listed buildings in Shropshire

Shropshire has 128 conservation areas. Under the council's Article 4 Directions you normally need planning permission to replace windows or external doors on walls that face the street, and the council says uPVC windows are unlikely to be supported where they would harm the area's character. Timber windows that match the original design are generally preferred; double glazed timber may be acceptable. A householder planning application costs £548. Listed buildings need listed building consent, which is free.

This is where costs rise: a timber sash can cost three times a uPVC one. In a listed building, repairing the existing windows and adding secondary glazing is often the preferred route. Check your address with Shropshire Council before you order. See also our windows and doors page.

Building Regulations and FENSA

Replacement windows must meet Building Regulations, including an energy standard. A FENSA or CERTASS registered installer certifies the work for you and you receive a certificate, which you will need when you sell. Without one, you need approval from building control.

Common questions

How much does it cost to replace all the windows in a three bedroom house?

In uPVC, usually £4,000 to £7,500 for a three bedroom semi with 8 to 12 windows, with about £5,500 typical in the Midlands. Aluminium is roughly £7,000 to £12,000 and timber £8,000 to £15,000 or more.

Is there VAT on new windows?

Yes. Double glazing and secondary glazing are charged at the standard 20% rate of VAT. Some websites wrongly say 0%; that rate covers heat pumps, solar panels and insulation, not windows.

Do I need planning permission to replace windows in Shropshire?

Usually not for like-for-like replacements. In a Shropshire conservation area with an Article 4 Direction you normally need permission to replace windows or doors facing the street, and the council says uPVC is unlikely to be supported there. Listed buildings need listed building consent. See Shropshire Council's Article 4 page.

Is triple glazing worth it?

It typically adds £100 to £300 a window, about 15% to 30%. It makes most sense on cold, north facing or noisy elevations. Modern double glazing already meets Building Regulations.

What is a FENSA certificate?

Proof that your new windows meet Building Regulations, registered with the council. Your installer issues it if they are FENSA or CERTASS registered. You will need it when you sell the house.
