What a uPVC window costs is set by its size, how many sections open, the glazing, the colour and any extras, not by a salesperson’s quote. Every price on this page comes from the same pricing engine as our online designer, worked out live at today's rates (2 November 2026) and including VAT.
As a floor: with the designer's standard options, the cheapest window we make today is a 300 × 430mm picture window (fixed) at £45.34 inc VAT, supply only (Picture Window (Fixed), a fixed window (no opening sashes), 300 × 430mm overall, white inside and out, double glazed (28mm), clear glass, 150mm cill (sill), no trickle vents (too narrow at this size)). From there, price scales with what the factory actually uses: frame metres, glass area and hardware.
Our online designer is the price calculator: pick a layout, type your width and height in millimetres and it prices that exact window as you choose the options. A 1200 × 1200mm Classic Combination in white with the standard options is £337.52 inc VAT; the link opens it in the designer at that size.
Here is what four popular layouts cost at common sizes today. Sizes are the overall width × height in millimetres, the way you type them into the designer, including the cill.
uPVC window prices by overall size: white, double glazed, inc VAT, supply only
Prices are supply only: we make the window and deliver it, and you arrange the fitting. Each price is for a white window with the options the designer starts with: 28mm double glazing, a 150mm cill, trickle vents where they fit, white handles and the standard key-locking espag lock. Where a trickle vent doesn't fit the openers at that size, the designer leaves it off and the price is without it. They're calculated from the same pricing as the designer, and each price opens that window at that size in the designer, so you can check it there (its exact configuration is in the link's title).
Prices include VAT at 20%. Delivery is extra: priced by straight-line distance from our factory (M28 2LY) to your postcode district, from £30, to mainland Britain addresses within 300 miles, not Northern Ireland, the Scottish Highlands or islands reached by ferry.

A dash means that layout isn't made at that size. Widths run 500-900mm for a Full Side Opener, 500-1300mm for a Top Opener over Fixed, 700-3000mm for a Side Opener + Fixed and 800-2200mm for a Classic Combination.

Under each amount is that window's total with the option picked, which opens it in the designer. Choose the option in the designer at the same size and the total changes by the same amount.

The five cost drivers, in order
Size: the frame is priced per metre of profile and the glass per square metre, so cost grows steadily with dimensions, not in steps
Openers: each opening sash adds sash profile, hinges, multi-point locking and a handle; a fixed pane is always the cheapest section
Glazing: toughened, laminated and triple units carry per-square-metre uplifts over the standard A-rated double unit; privacy glass adds £27.07 on a 600 × 900mm Full Side Opener (£175.09 in total) and £79.53 on a 1200 × 1200mm Classic Combination (£417.05 in total)
Colour: foiled colours price per metre of profile, one side or both; white is the base
Extras: cills (85-225mm) and frame extenders price per metre; trickle vents per opener
What colour adds: one window, three finishes
Foiled colours are priced per metre of the profile in your window, so the extra depends on the window rather than being a flat percentage. Here is the same 1200 × 1200mm Classic Combination in white, with Anthracite Grey outside and white inside, and with Anthracite Grey on both sides:
Example uPVC window prices: white compared with Anthracite Grey, inc VAT, supply only
When you pick a coloured outside, the designer sets the inside to white, so you only pay for foil on both faces if you ask for it: choose "Same as external" for that. Each price opens the designer on that window, colour and inside already picked. There are more examples on our grey uPVC windows and black uPVC windows pages.
In white, the window is: Classic Combination, an opening window, 1200 × 1200mm overall, white inside and out, double glazed (28mm), clear glass, 150mm cill, trickle vents: 2000 (300mm), white handles, standard key-locking espag lock.

Why quotes for 'the same window' vary so much
Installed quotes bundle the window with survey, fitting, disposal, commission and company overhead, which is why three installers can quote three very different prices on one house. A supply-only price is just the manufactured window: what you see here is the factory sell price, and the fitting is whatever your local tradesperson charges for the labour. Comparing like-for-like means comparing the specification: system, glazing unit, colour and hardware.
Where the money goes in the frame
Roughly speaking, a window is profile, glass and hardware. The outer frame runs the perimeter; every opener adds its own sash perimeter inside it; mullions (the upright bars between panes) and transoms (the horizontal ones) divide sections. Glass is priced by area with a minimum per pane, which is why several small panes cost more than one big pane of the same total area. Hardware is per opener. Our designer prices all of it live, so the fastest way to understand your window's cost is to build it and toggle the options.
What the price includes, and what it doesn't
The window made to your millimetre sizes in Eurocell Eurologik 70mm uPVC
The sealed glass units, 28mm A-rated double glazing as standard, supplied separately for glazing once the frame is in
Handles, hinges and multi-point locks on the opening sashes, fitted at the factory
A 150mm cill and trickle vents where they fit, supplied loose, ready to fit
VAT at 20%
Not included: fitting, and what it needs (fixings, packers, silicone, trims and disposal of your old frames), because we supply only. Upgrades such as a colour, other glass or a better lock add to the price, as the tables above show.

Today's from-prices by layout
Each is a complete window in that layout at the smallest size we make it (the size under the price), in white with 28mm double glazing and a 150mm cill, with trickle vents where they fit, white handles and the standard key-locking espag lock on the opening sashes: the same starting figure our window listings show. Where a trickle vent doesn't fit at that size, the price is without it. Each one opens the designer at that size and price, with its exact configuration in the link's title. Your sizes, glass and options are priced in the designer.
The bay is the one our bay window designer opens with, not a starting price: a bay is priced from its frames, poles and cill welds, so a smaller one costs less. The link opens it in the bay designer at that price.

Does anthracite grey cost more than white?
Yes, foiled colours price per metre of profile. For example, a 1200 × 1200mm Classic Combination is £337.52 in white and £404.70 with Anthracite Grey outside and white inside, or £526.42 with Anthracite Grey both sides, inc VAT, with the designer's standard options. Delivery is extra, from £30 by distance from our factory, or collect free: see delivery and collection. The designer shows the exact uplift for your window before you commit.
Is triple glazing a big cost jump?
It prices per square metre over the standard 28mm double unit, so the uplift depends on your glass area. Today it adds £50.24 to a 600 × 900mm Full Side Opener (£198.26 in total) and £95.26 to a 1200 × 1200mm Classic Combination (£432.78 in total), inc VAT, in white with the designer's standard options otherwise. Delivery is extra, from £30 by distance from our factory, or collect free: see delivery and collection. The designer shows the uplift for your own sizes as you pick it.
Are there hidden costs at checkout?
Delivery is the only addition, calculated from your postcode's distance from our factory and shown before you place the order. The window price is the window price.
Do bigger orders get better prices?
Windows price individually, but delivery is per drop, so one delivery of six windows beats six deliveries. The prices are already our trade prices, the same for everyone.
