Are supply-only sliding doors right for homes in South Glamorgan?
Before you settle on a door type, it helps to know what supply-only sliding doors do well and what to check before you order.
Measuring an opening at a South Glamorgan property yourself? Take three widths and three heights and use the smallest of each, then follow our tolerance guidance.
If your South Glamorgan property is on a narrow street or has no parking outside, tell us before delivery so a sensible drop-off point can be agreed.
- Every door is confirmed back to you in a written specification before ordering, so frame size, handing, colour and glass can be checked one last time.
- Clear measuring guidance and tolerances are provided before you order, helping you give dimensions the factory can build to accurately.
- Supply-only costs roughly two thirds of the fitted guide price for the same door, which can make sense when you already have a capable fitter on site.

Daylight and glass in South Glamorgan
Sun angles matter for big glazed doors. Around South Glamorgan, midday sun reaches about 62° in summer and drops to about 15° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

Who handles approvals?
If you buy supply only, whoever fits the door is responsible for Building Regulations compliance and safety glazing. In Wales a replacement door must meet the Building Regulations as applied in Wales, arranged through a registered installer or Building Control.
Questions about supply-only sliding doors in South Glamorgan
Do you deliver supply-only sliding doors to South Glamorgan?
Yes. We deliver made-to-measure supply-only doors across South Glamorgan, with standard delivery to mainland Britain at £95. Deliveries to Northern Ireland and the islands are quoted individually.
Who is responsible for measuring a supply-only door?
For supply-only orders you are responsible for measuring the opening and giving us the sizes, unless you book one of our surveys. We provide measuring guidance and tolerances, and confirm the sizes back to you in writing before ordering. If you book a survey, our surveyor measures and the responsibility for the sizes then sits with us.
What does supply-only mean?
Supply-only means we manufacture and deliver your made-to-measure sliding door, but we do not fit it. You, your builder or your own installer carry out the installation. The door uses the same frames, glass and hardware as our fitted doors. Supply-only is priced at roughly two thirds of the fitted guide price for the same door, plus delivery.
How heavy are supply-only sliding door panels?
Sliding door panels with double glazed safety glass are heavy, and large panels can weigh well over the safe limit for one person to lift, especially with triple glazing. Plan for enough people on site to unload, carry and position each panel, and keep the route from the delivery point to the opening clear and level.
