We can advise on what will or won’t be accepted as part of planning, and how to comply with building regulations. It’s our expertise in this area that has allowed us to take on many challenging and exciting period restoration projects.

Sash windows, listed buildings and properties in conservation areas

Conservation areas are of special architectural or historic interest, meaning any work carried out on your home must preserve or enhance the character of its surroundings. This doesn’t always mean that you can’t restore or replace your period sash windows, but it will mean that you need windows that complement your building and its environment.

For historic properties and homes in conservation areas, we can restore sash windows in a way that preserves their intended appearance, and that makes use of the materials and methods originally used to make them. Our draught proofing and slim line double glazing is also a non-intrusive way of insulating your windows from the inside (though listed buildings may be limited to single glazed units). However, it’s worth remembering that it is a criminal offence to carry out work that needs listed building consent without obtaining it beforehand, and you’ll need to contact your local council’s Conservation Officer for guidance first. We’re more than happy to help advise you with this.

Advice for period sash windows and their restoration

When embarking renovation of a Listed property it’s always useful to research as much as you can. We’ve gathered a list of resources that you may find helpful:

The Society For Protection Of Ancient Buildings

The Listed Property Owners Club

Historic England

Historic Scotland

Planning (Listed Buildings and Conservation Areas) Act 1990

If you own a listed property and are thinking of renovating the period windows we always recommend you speak with your local conservation officer first to check if you require Listed Building Consent or Planning Permission before any work commences. We can then provide a window-by-window quotation detailing the work required, plus any accompanying documentation your planning officer may wish to see.

English Heritage has also recently stated: “Sash windows are a precious part of our built heritage that makes the places we work and live special and most people find them attractive. But keeping them is not just a matter of taste. It also makes economic and ecological sense.”
