What does skylight replacement in Flitwick involve?
Thinking about skylight replacement in Flitwick? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for skylight replacement include older extensions due a modern rooflight.
From Flitwick to Ampthill, Dunstable and Bedford, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight replacement in Flitwick
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.
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.

Questions about skylight replacement in Flitwick
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.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Is the survey in Flitwick 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 Flitwick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
