What does skylight replacement in Alnwick involve?
For Alnwick homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Morpeth (27 km) and Ashington (28 km). We offer a survey date when we reply to your enquiry.

Before you order: points to check

- Upstand and roof condition decide the scope
Planning and building rules for Alnwick
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.

Questions about skylight replacement in Alnwick
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.
Will I need planning permission in Alnwick?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
Can you work alongside my builder in Alnwick?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
