Supply Only Windows & Doors

Made-to-measure products, quick turnaround, and delivery across all London areas.

Truth be told, “supply only” means different things to different people. Some imagine it’s just picking up a frame and walking away, but in my experience, most homeowners and trade fitters want something a bit more reliable — proper guidance, accurate measurements, and products that turn up when they’re supposed to.

Whether you’re a trade installer looking for a dependable supplier or a homeowner who already has someone to fit your windows and doors, our Supply Only service is built to make the whole process simple… or at least as simple as real-world projects allow.

How the Process Works (for Trade & Homeowners)

If you're in the trade:

Most trade customers already know exactly what they need. You send us your measurements, specs, and any drawings or details, and we’ll get straight to it. We double-check the tricky bits — profile choice, glazing options, hardware — just to make sure everything lines up. Nothing worse than losing a day on site because of a tiny oversight, so we try to prevent those.

Turnarounds are quick, too. Honestly, it depends on the product, but most people are pleasantly surprised when they see how fast we move.

If you're a homeowner:

Homeowners sometimes hesitate, and that’s completely normal. Measuring for windows and doors can feel a bit daunting. If you already have a builder or installer, great — they usually take the measurements. If not, we can guide you through what’s needed, and we’ll tell you straight if something looks off before it goes into production.

Once we’ve got the final sizes, the rest is smooth sailing. We manufacture everything made to measure, no generic “one-size-fits-most” stock.

Whether you are looking for the modern, slim profiles of Aluminium Windows or the reliable efficiency of uPVC Windows, we have a style to suit every home. Our collection extends to high-security Aluminium Doors and uPVC Doors, as well as specialized Roof Windows designed to bring more natural light into your living space. Every item is crafted through our Bespoke Manufacturing process, ensuring your new windows and doors fit your property perfectly.

Delivery Across London (and Greater London)

One thing people often worry about is delivery — “Will you even come to my area?”

Short answer: yes.

We deliver across all London postcodes and most Greater London areas. You’ll notice our drivers know these routes like the back of their hand; navigating London’s streets is almost a trade skill by itself. And unless there’s some rare road chaos (which, being London, does happen), we try our best to give you a reliable delivery window so you’re not waiting around all day.

If you prefer, collection is also available — some trade customers like grabbing the order early so they can head straight to the job.

Quality Products, Quick Turnaround

A lot of companies talk about “quality,” but for us it’s pretty straightforward: we only supply products we’d be happy installing ourselves. The profiles, glazing, locks, hinges — every part matters. And because everything is built to order, the fit tends to be spot-on.

Most supply-only orders are ready faster than people expect. Still, every job has its quirks, so we’ll give you an honest timeline upfront rather than pretend everything is magically instant.

We offer flexible solutions to fit your specific project needs. For a completely hassle-free experience, our Supply & Fit service covers everything from the initial onsite measurement to the final professional installation. If you are a builder or have your own installer ready, we also provide Supply Only Windows & Doors, delivering premium, made-to-measure products directly to your site.

FAQs — Supply Only

Final thought:

If there’s one thing I’ve learned after years in this trade, it’s that people don’t just want a product — they want clarity. A straight answer, a fair lead time, and something that fits the first time. That’s really what our Supply Only service is built around. If you’ve got a project coming up, big or small, just ask — half the job is simply pointing you in the right direction.
