How to use this website
Every window and door here is made to measure, and you price it yourself in about a minute, with no callbacks, no “request a quote” forms. Here's the whole journey, from picking a style to placing the order.
Before you start: measure first
You'll get the most out of the designer with your sizes already in hand, and our measuring guide shows you how in five minutes. And if you're fitting the windows yourself, the fitting and toe-and-heel guides cover the job end to end.
- 1
Pick a style that's close to what you need
Head to Windows and browse the styles (fixed lights, side openers, top vents and combinations), or go to Doors for uPVC and composite doors, or Bifolds for aluminium bifold doors. The style is just your starting layout: every window is made to your exact sizes, so pick the arrangement of openers and fixed panes you want and don't worry about the sizes shown.

Enter your sizes on the drawing
Use the big Width and Height boxes around the drawing. Sizes are overall. They include the cill, if you choose one, and any frame extenders you add, just like a fitter would quote them. The drawing redraws to scale as you type, and the size limits under it show what we can make. Not measured up yet? Read our measuring guide first. It takes five minutes.

Move the mullions and transoms if you like
The smaller boxes under and beside the drawing are the individual sections. Type a size and that section is set. Sections you've set stay put while the flexible ones absorb the change. If something can't be made (say a vent has hit its maximum width), a message pops up telling you exactly why and what to change. Openers are always kept within manufacturing limits automatically.

Choose colours, glass and hardware
Work down the options: outside and inside frame colour, glazing (double, toughened or laminated), obscure glass for bathrooms, cill size, handle colour, trickle vents and frame extenders. Every choice shows the real difference it makes to your price: “+£21.49” means picking it adds exactly that, and “−£…” means you'd save. Ticking the fire escape box holds the opener sizes needed for an egress window.

Watch the live price and breakdown
The price panel updates instantly as you design, and the breakdown shows where the money goes: frame and hardware, colour, glazing, cill and vents, all including VAT. There are no hidden extras at the end: what you see is the made-to-measure price for exactly what's on the drawing.

Add to basket, and keep designing
Set the quantity and add the window to your basket. You can add as many windows and doors as you like in one order, and everything in the basket can be reopened and edited later. Click any item to go back to its drawing with all your choices intact.

What happens after you order
We check your order within one working day, then email to confirm it with your delivery or collection date and your invoice. How buying works covers every step from there: cancelling, lead times, delivery day, the 72-hour check and guarantees. Before you order, our guide to buying uPVC windows online covers what to check first.
Ordering aluminium bifold doors
The bifold designer works the same way. Enter the overall width and height (a bifold always has a cill, and the sizes include it), then pick 2, 3, 4 or 5 leaves; your width decides which you can have. Choose how the leaves fold, viewed from outside: all to the left, all to the right, or split between the two. If a layout has no master door, the designer tells you that 2 doors must open at once. Then pick the colour, opening in or out, the threshold, the cill and the handle colour, and add the set to your basket. Clear toughened double glazing is included. Measure up first with the bifold measuring guide.
