Replacing Windows

You will require Listed Building Consent to replace any windows in a Listed Building, on any elevation, regardless of what you are replacing them with.

Each Listed Building application we receive is judged on its own merits.

However, generally, it is unlikely that consent will be granted for any UPVC work to listed buildings.

An application will be judged at several levels:

• In cases where the existing windows are of historic or architectural interest such that would warrant their retention, we would look at possibilities or repair and refurbishment in preference to wholesale replacement.
• If we believe the condition of timber windows to be so poor as to prohibit effective repair, we would generally be seeking like for like replacement with purpose made joinery.
• Where the existing windows themselves are more modern installations, we would expect the proposed replacements to be of a style and construction appropriate to the particular Listed Building.

Listed Building Consent is also required to alter the colour of windows, and to install secondary glazing systems.

Several national companies offer window refurbishment services, both in terms of repair of window types ranging from timber sashes to metal frames and replacement handmade glass, and in upgrading of thermal and acoustic performance.

Many of these advertise in the Building Conservation Directory.

However, there may well be other smaller, local companies who can offer a comparative service. Please be aware that the Council can neither endorse nor recommend any product, company or supplier.
