Conservation rooflights in Hatfield: what is involved?
For Hatfield homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Hatfield, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
From Hatfield to Welwyn Garden City, St Albans and Potters Bar, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Flashings for slate or plain tile
- Central vertical glazing bar
- Toughened or laminated double glazing
- Blinds
- Steel or aluminium frames
- Often preferred by conservation officers
- Traditional slim profile, sits low in the roof
What to check first
- Conservation officers may specify size and position
- Projection above the roof line is limited — usually as flush as possible
Planning, building control and Hatfield
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Will the council accept it?
We cannot promise an outcome, but a slim conservation profile fitted low in the roof is the type many conservation officers ask for.
Do I need consent for a conservation rooflight?
On a listed building you need listed building consent. In a conservation area, check with the council — many areas have Article 4 directions affecting roof alterations.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
Can you work alongside my builder in Hatfield?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Hatfield free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
