Double-glazed timber replacements are now allowed as an option for certain windows and doors in protected building, after the Development and Planning Authority updated its guidance.
Simple sash windows or those with curved heads can now be replaced with double-glazed wooden versions, provided they replicate the original’s appearance.
However, rare or ornate elements must be repaired rather than replaced, and a replacement is only permitted if the item is beyond repair and must be a precise like-for-like match.
Planning permission is still mandatory for any planned replacements, and applications must include the specific details outlined in Section 6 of the updated guidance.
Deputy Neil Inder, President of the DPA, said these changes aim to maintain Guernsey’s heritage while allowing owners to improve energy efficiency.
“Owning a protected building comes with the responsibility to look after what makes it special, but this should not be an unwanted burden.
“These changes will maintain Guernsey’s heritage, while giving the owners the opportunity to improve the energy efficiency and quality of their homes.”
The DPA President further claims that this shift reduces the burden on property owners and has already resulted in a high volume of applications.
“Signalling this change has been welcomed by property owners and there has been a flurry of applications pre-empting these changes.
“I’m grateful to the conservation officers within the Authority who have assisted immensely to make this positive change.”
