What do conservation rooflights involve?
Our conservation rooflights service in Northumberland covers slim, low-profile steel-look rooflights for period and listed roofs. We survey every job before fixing the price.
Many North East homes have loft rooms that benefit from larger roof windows with blackout blinds. North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen.

Planning and building rules in England
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.
What do conservation rooflights cost in Northumberland?
These are typical supply-and-fit ranges. For an address in Northumberland, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.

| Standard conservation rooflight Typical | £2,035 – £2,755 | £1,695 – £2,295 |

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
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.
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.
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
Do I need to be at home for the survey in Northumberland?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
