VELUX roof windows come in five core types across dozens of sizes, and the combination of type + size code + glazing determines everything about the price. This guide maps the range so you can walk into a quote knowing exactly what to ask for — and what it should cost, per our 2026 price guide.
The five types
Centre-pivot — the default VELUX. The sash rotates around a central hinge: cheapest to buy (from ~£330), easy to clean (it spins right round), and fine for almost any loft. Its one quirk: the open sash leans into the room. Full detail in our centre-pivot guide.
Top-hung — hinged at the top, opening outward for an unobstructed view and full head height at the window. Costs £100–£180 more than centre-pivot like for like, and the wide clear opening is how loft conversions meet escape-window rules. If the window is the room’s main view, buy top-hung.
INTEGRA electric — powered opening, closing and blinds from a wall pad or app, with a rain sensor that shuts the window when the weather turns. Needs a mains feed run to the window. See our INTEGRA electric guide.
INTEGRA solar — the same automation, powered by a solar cell and battery: no wiring, which makes it the retrofit-friendly powered option and the answer for out-of-reach windows. Around £830–£1,230 supply depending on size; our solar guide covers it properly.
Cabrio balcony — the party trick: a window that folds out into a small balustraded balcony. From £2,400 supply, £3,000+ fitted, and transformative in the right loft.
(VELUX also makes modular skylights for commercial roofs, flat-roof units, and sun tunnels for windowless spaces — different products for different problems.)
Sizes: learn the code, control the cost
Every VELUX carries a size code: letters = width band, numbers = height. CK04 (55×98cm) and MK06 (78×118cm) are common loft sizes; UK10 (134×160cm) is the big statement unit. Full grids, old-code conversions and a decoder live in our size chart. Three practical points:
- The code drives the price more than the type does — a large centre-pivot costs more than a small top-hung.
- Bigger is disproportionately better for light — one MK08 usually beats two tiny units for daylight, and costs less than two installs. If even the largest codes won’t do, that’s bespoke territory.
- Replacing an old VELUX? The company publishes conversion charts mapping discontinued codes to current models — a decades-old window usually has a drop-in modern equivalent, which keeps a like-for-like swap at £500–£800 fitted.
Finishes, glazing and blinds
Frames: white-painted timber (the default), bare pine (varnish it or regret it), and white polyurethane — the moisture-proof pick for bathrooms and kitchens. Glazing: standard double, low-energy laminated, and triple-glazed options; the step up adds £150–£400 but pays back in comfort directly under the glass. Blinds: the ecosystem is VELUX’s quiet moat — blackout, thermal and awning blinds sized to every code; see our complete blinds guide. OEM blinds cost £100+; compatible third-party blinds start around £30 and fit the same brackets, which is one of the easiest savings in the whole project. You can browse current window and blind prices on Amazon as well as the builders’ merchants — merchant pricing varies more than people expect, so check both.
What it all costs, in one view
| Setup | Typical 2026 price |
|---|---|
| Small manual centre-pivot, fitted | ~£655 |
| Mid-size top-hung, fitted | £755–£995 |
| INTEGRA solar, fitted | £1,155–£1,555 |
| Cabrio balcony, fitted | £3,050–£3,470 |
| Like-for-like replacement | £500–£800 |
Installation itself runs ~£325/day for a two-person team, plus ~£500 scaffolding where the window can’t be fitted from inside — the full breakdown lives in our skylight installation cost guide, and planning permission is rarely an obstacle.
Is VELUX the right brand at all?
It’s the safe default — fitters know it, parts exist forever, and the 10-year guarantee is real. But it’s not the only credible choice: Fakro undercuts it by 15–25% at comparable spec, and the alternatives are worth a look for secondary rooms or multi-window jobs where the savings stack. Whichever brand you land on, spend your attention on the installer — the window is only ever as good as its flashing.
Frequently asked questions
What types of VELUX roof window are there?
Five core types: centre-pivot (the standard), top-hung (clear-view, opens outward), INTEGRA electric and INTEGRA solar (powered opening with rain sensor), and Cabrio balcony windows that fold out into a small balcony. All come in multiple sizes, finishes and glazing specs.
How do VELUX size codes work?
The letters give the width band and the numbers the height — CK04 is 55×98cm, MK06 is 78×118cm, UK10 is 134×160cm, and so on. The code, not the type, is the biggest driver of price, and VELUX publishes conversion charts from decades-old codes for replacements.
How much do VELUX roof windows cost?
£330–£1,230 to buy in 2026 depending on size and spec, or roughly £655–£1,555 fitted for standard configurations. Balcony systems cost £2,400+ for the window alone.
Which VELUX type is best for a loft conversion?
Top-hung for the main room — the clear opening meets escape-window requirements and gives the best view. Centre-pivot for everywhere else, and INTEGRA solar where the window is out of reach.
