What do conservation rooflights in Northwich involve?
For Northwich 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.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Northwich, as anywhere, conservation rooflights are the usual choice for slate and plain-tile roofs where a quiet roofline matters.
From Northwich to Winsford, Warrington and Runcorn, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Northwich
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.
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. 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.

Questions about conservation rooflights in Northwich
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 you copy an original rooflight?
Some makers produce bespoke sizes to match an existing opening. We can survey and quote.
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.
How do I book a survey in Northwich?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Northwich?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
