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

Compact 1800mm x 900mm plasterboard sheet, ideal where access is tight such as lofts, bathrooms, and stairwells. 

Square edge profile creates a clean, flush joint that is intended for skim plaster finishes. The ivory paper face provides a solid base for decoration. 

Lightweight construction allows easy handling for ceilings and partitions. 

At 9.5mm thick, this board is easier to lift and fit overhead, making it most suitable for ceilings and non-loadbearing partitions.
