Six of the case studies on this site are from North Yorkshire: three jobs in Harrogate, two in York and a 15-window conservation replacement in Helmsley. They cover very different houses and roofs, and that variety is what this page is about.
Skylight Fitters is a VELUX® Pro Partner Ambassador working nationwide. We have no office in North Yorkshire; our own accredited fitters travel to each job, so visits are planned in advance around the roof, the access and the parts needed.

Harrogate: tiled roofs and windows at the end of their life
Our Harrogate jobs were on tiled roofs rather than slate. In HG1, nine worn-out VELUX windows in a profiled concrete tile roof were replaced with triple-glazed natural pine GGL windows. In HG3, eight leaking non-VELUX windows in a clay pantile roof had been fitted with no expansion gap; we adjusted every opening before fitting VELUX GPU top-hung windows. The HG1 sun tunnels went into concrete interlocking tiles. The lesson from all three: the flashing has to suit the tile profile, and earlier poor installation is worth putting right rather than repeating.
York: conservation areas, slate terraces and new-builds
York is its own unitary authority, so planning questions go to City of York Council rather than North Yorkshire Council. The council lists 35 conservation areas in the city. Our York work shows two ends of the housing stock: twin CABRIO balcony windows in the natural slate roof of a YO1 terrace, carried up three flights of narrow stairs, and solar upgrade kits, blinds and App Control for nine high windows at a YO19 new-build.
Helmsley and the North York Moors
Helmsley sits on the southern edge of the North York Moors National Park, and the town is split between two planning authorities: the North York Moors National Park Authority covers the part inside the National Park, and North Yorkshire Council covers the rest (see the Helmsley Plan). At our Helmsley job we replaced 15 VELUX GVT 154 windows in a slate roof with GGL CK04 2570H conservation windows, EDL slate flashings, underfelt and insulation collars, solar operation and App Control – a traditional look on the roof with modern operation.
Planning permission: which authority?
Roof window changes on listed buildings, and some changes in conservation areas, can need planning permission or listed building consent. Check with the right authority for the address before you commit:
- York – City of York Council (see our York conservation advice).
- Harrogate and most of the county – North Yorkshire Council planning and conservation.
- Inside the North York Moors National Park – the National Park Authority. Helmsley is split between the Authority and North Yorkshire Council.
We can suggest suitable VELUX conservation windows and give you product details for an enquiry or application.

North Yorkshire VELUX questions
Where in North Yorkshire have you worked recently?
Our published North Yorkshire jobs are in Harrogate (HG1 and HG3), York (YO1 and YO19) and Helmsley. Each one has its own case study with photos. We cover the rest of the county too; send us your postcode and we will confirm.
Who do I ask about planning permission for roof windows?
It depends on the address. In York it is City of York Council. Harrogate and most of the rest of the county come under North Yorkshire Council. Inside the North York Moors National Park, the National Park Authority is the planning authority, and Helmsley is split between the two. Check before you change roof windows on a listed building or in a conservation area.
Do you have an office in North Yorkshire?
No. Our fitters are based throughout the UK and travel to each job, so North Yorkshire visits are booked in advance with the right windows, flashings and blinds on board.
Can you work on slate, pantile and concrete tile roofs?
Yes. Our North Yorkshire jobs include natural slate in York YO1 and Helmsley, clay pantiles in Harrogate HG3, and profiled concrete tiles in Harrogate HG1. Each roof covering needs a flashing kit made for it.
