VELUX and Roof Window FAQs
Usually not — if the windows don’t project more than 150mm above the existing roof plane and are at least 1.7m above floor level. In conservation areas, additional restrictions may apply.
Not usually, but the same rules apply to VELUX as with most roof windows. Most VELUX installations fall under permitted development, but we’ll advise based on your specific property and local council.
There’s no fixed limit — it’s about space, structure, and light needs. We regularly install 2–4 windows per room in conversions and extensions across Lincolnshire and beyond.
Yes — we handle all scaffolding for East Anglia and East Midlands (https://pjsscaffold.co.uk/)jobs, whether it's a simple rooflight swap or a new loft conversion.
Yes. After installation, we can plaster around the new windows and re-render outside if needed. We leave your space finished, not half-done.
We do. Our team installs electric VELUX windows, solar-powered units, and integrates mains or remote operation systems — all Part P certified.
Yes. We’ll advise you on size, type, finish, blinds, and ventilation — with recommendations based on your roofline, layout, and location.
We specialise in VELUX, but also fit other rooflight brands, such as Fakro, Keylite, and The Rooflight Company. Let us know what you’re after, and we’ll advise accordingly.
The cost of a VELUX window depends on the size, model, and features — like electric opening, solar power, or integrated blinds. Installation costs vary too, especially if structural work, plastering, or scaffolding is required. At Kendle Building, we provide tailored roof window quotes across Stamford, Spalding, and the East Midlands to suit your home and budget.
Replacement costs depend on whether you’re swapping like-for-like or upgrading to a newer model, and whether the plasterwork, flashing, or frame needs repair. We regularly replace old roof windows in Stamford, Bourne, and across the region — and always give clear quotes with no surprises.
VELUX blinds come in a range of styles — from blackout and thermal to Venetian or roller. Costs depend on the material and whether you’re choosing manual, electric, or solar-powered options. We’ll guide you through the best roof blind options and can install them as part of your full roof window package.
Yes. Roof windows are one of the simplest ways to boost natural light, ventilation, and kerb appeal — especially in loft conversions, extensions, and heritage upgrades. Homeowners across Cambridgeshire, Lincolnshire, and Northamptonshire often find that a well-placed skylight improves both the look and energy efficiency of their space.
Definitely. VELUX windows are built to last, with excellent thermal insulation, rain sensors, and low-maintenance timber finishes. We recommend them across most of our East Midlands projects because they’re reliable, stylish, and well-supported with warranties and accessories.
There are three main types: centre-pivot, top-hung, and flat roof windows.
VELUX also offers electrically operated and solar-powered options. Whether you’re in a period cottage in Stamford or a modern home in Peterborough, we can recommend a style that fits both the roofline and your layout.
Yes — pitched roofs are ideal for most VELUX and rooflight installations. We regularly fit them in all differrent homes and commercial properties across Cambridgeshire, Northamptonshire, and Lincolnshire
Yes, but they’re a different product to pitched roof windows.
VELUX makes specific flat roof windows and domes. These are perfect for home extensions or single-storey homes across the East Midlands
That depends on the orientation of your home and the room use.
South-facing roof slopes give you the most light, but we can advise during your site visit. We help homeowners across East Anglia make the most of natural light.
Most do — especially centre-pivot and top-hung designs. But fixed rooflights are available if you only want natural light, not ventilation.
Yes, all standard VELUX roof windows come double glazed for insulation and thermal efficiency. Triple-glazed options are also available for high-performance homes.
Most are made from timber with a white-painted finish, though moisture-resistant PVC options are available for kitchens and bathrooms. We’ll help you choose what suits your space best.
With proper fitting, VELUX windows can last 20–30 years or more. In fact, many of our customers across Cambridgeshire, Lincolnshire, and Northamptonshire are replacing units that were first installed in the 1990s.
It depends on the brand and installation quality, but well-fitted units last at least 20 years. Regular maintenance and weatherproof flashing extend that lifespan.
