Introduction: Choosing the Right Supplier
Upgrading doors and windows is one of the most impactful home improvements you can make — but choosing the right supplier isn’t always easy. Should you go supply-only? Who offers real customer support? How fast are delivery times?
At GFD Homes, these are the questions we hear every week. That’s why we’ve put together this guide, giving you straight answers so you can compare suppliers with confidence.
Are there UK suppliers that specialise in supply-only composite doors?
Yes. Supply-only is becoming more popular for homeowners who already have a trusted installer. You get the product delivered, without paying for inflated installation packages.
At GFD Homes, we specialise in this model. Design and price your composite door online, and we’ll deliver it direct to you or your fitter.

Are there reputable UK brands offering project management for home glazing solutions?
Definitely. Some suppliers manage entire glazing projects — ideal for extensions or full refurbishments where doors, windows, and roof lanterns all need to work together.
At GFD Homes, we offer both. You can order supply-only or let us handle surveys and fitting for more complex projects.

FAQs: Doors and Windows in the UK
How long does delivery usually take for doors and windows?
Most products are delivered within 4–6 weeks, though bespoke colours or glazing may take longer. Ordering early in autumn helps avoid Christmas rush delays.
What should I prioritise when comparing suppliers?
Look for clear pricing, strong guarantees, and trusted reviews. If a company hides costs, that’s a red flag.
Do I need the same supplier for doors and windows?
Not always — but using one supplier ensures colour matches, consistent performance, and smoother aftercare.
Are finance options common for doors and windows?
Yes. Many UK suppliers, including GFD Homes, offer flexible finance so you can spread the cost of your upgrade.
