Glass links & glass box roofs in Witham: what is involved?
Our glass links & glass box roofs service in Witham covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Typical uses for glass links & glass box roofs include listed and period buildings where the old wall should stay visible.
Witham is around 30 km from Southend-on-Sea, and we survey and fit throughout that part of Essex, including the CM8 district.

Consents for glass links & glass box roofs in Witham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Glass links & glass box roofs in Witham: questions
Who designs it?
Your architect, or we produce a survey-based design that the glass manufacturer engineers.
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 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.
Is the survey in Witham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Witham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
