What does skylight replacement involve?
Skylight replacement in Suffolk means replacing tired domes and failed glass with a modern rooflight. Every quote follows a survey of the roof and the room below.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights.

Planning and building rules in England
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
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.
Do I need to be at home for the survey in Suffolk?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
