How we approach skylight replacement in Christchurch
Thinking about skylight replacement in Christchurch? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Think of skylight replacement for older extensions due a modern rooflight.
From Christchurch to Bournemouth, New Milton and Poole, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Christchurch
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Questions about skylight replacement in Christchurch
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Do you offer skylight replacement in Christchurch?
Yes. We carry out skylight replacement in Christchurch and across Dorset. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Christchurch?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
