What do glass links & glass box roofs involve?
Our glass links & glass box roofs service in Bedfordshire covers frameless glass links joining old and new buildings. We survey every job before fixing the price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement.

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. 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.

- 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
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
Do glass links need planning permission?
Often, yes — and listed building consent if either building is listed. We can provide drawings and product data for your application.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Do I need to be at home for the survey in Bedfordshire?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
