How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

Product Overview
White primed MDF window board in a bullnose profile, measuring 25mm x 244mm in a 3660mm length. Designed to form a smooth decorative sill, this board conceals construction junctions while offering an extended finished surface.
The bullnose profile features a rounded front edge for a soft decorative appearance. The 244mm width provides extended coverage, making it suitable for deeper window reveals or where increased projection is required.
Manufactured from MDF, the board is stable, uniform, and free from knots or grain defects found in timber. Its primed coating provides a smooth, consistent base ready for a chosen topcoat finish.
Supplied in 3660mm lengths, the product is easy to cut, handle, and fit, ensuring efficient installation with minimal preparation.
