How we approach skylight replacement in Hatfield
Our skylight replacement service in Hatfield covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of skylight replacement for older extensions due a modern rooflight.
Hatfield sits about 4 km from Welwyn Garden City and 8 km from St Albans, and we cover the whole AL10 postcode district and the roads in between.

Do you need permission in Hatfield?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Common questions
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
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.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
