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
22mm P5 Moisture Resistant Chipboard Flooring measuring 2400mm x 600mm. This high-density particleboard is engineered specifically for structural flooring applications where increased humidity or incidental moisture may occur. The panels feature precision-machined tongue-and-groove profiles on all four edges, enabling an interlocking "floating" or fixed deck that significantly reduces the risk of independent board movement and surface squeaking.
At a 22mm thickness, these boards provide a superior load-bearing sub-base with enhanced spanning capabilities, making them the standard choice for new build construction and heavy-duty domestic renovations. The P5 classification ensures superior dimensional stability and structural integrity compared to standard P2 grades, resisting the swelling and degradation typically caused by moisture ingress during the construction phase. The 600mm width is specifically designed for ease of handling in confined spaces, such as attics or narrow corridors, while ensuring the structural integrity of the floor at a thickness of 22mm.
Features & Benefits
- P5 moisture-resistant grade: Certified to EN 312 for load-bearing use in humid internal conditions, including kitchens and bathrooms.
- High-density particleboard: Engineered construction provides high compressive strength and resistance to structural weakening from moisture.
- Tongue-and-groove profiles: Precision-fit edges on all four sides ensure a secure, interlocking joint that minimises vertical movement between panels.
- Sanded surface finish: Provides a smooth, level face that is ready for the direct application of underlays, carpets, or laminate flooring.
- Enhanced workability: The board composition allows for clean cuts and secure fastener retention when using standard woodworking tools.
- 2400mm x 600mm dimensions: Optimised for rapid coverage and easy manual handling through standard doorways and up staircases.
- Structural 22mm thickness: Designed for installation over joists at 600mm centres, providing maximum spanning strength and floor stiffness.
Applications
- Heavy-duty domestic flooring: Increased 22mm thickness allows for installation over wider joist centres up to 600mm without excessive deflection.
- High-traffic kitchen and utility floors: Enhanced structural rigidity makes 22mm boards suitable for areas with heavy appliances and constant foot traffic.
- Mezzanine and platform decking: 22mm profile serves as a cost-effective structural deck for home office mezzanines and internal storage platforms.
- Garage workshop overlays: Laid over concrete with a damp-proof membrane to create a high-capacity, thermally improved floor surface.
- Underfloor heating substrates: Structural 22mm thickness provides a stable base when installed over joists containing underfloor heating spreader plates or pipework.
Installation Guidance
- Acclimatise the boards: Store panels flat in the room of installation for 48 hours to equalise moisture content with the surrounding environment.
- Check joist spacing: Ensure joists are level and spaced at maximum 600mm centres for 22mm boards to prevent excessive deflection under load.
- Apply joint adhesive: Run a continuous bead of D3 or D4 grade moisture-resistant PVA glue along both the tongue and the groove to create a silent, waterproof bond.
- Stagger the joints: Lay boards in a staggered "broken bond" pattern, ensuring that short-end joints always fall directly over a supporting joist.
- Maintain expansion gaps: Leave a minimum 10mm to 12mm expansion gap around the entire perimeter of the room and at all rigid obstructions like radiator pipes.
- Fixing intervals: Secure boards using ring-shank nails or carcass screws at 200mm intervals along supported edges and 300mm on intermediate joists.
- Countersink fasteners: Ensure all screw or nail heads are driven 2mm below the surface to prevent "grinning" through the final floor covering.
- Seal perimeter edges: Treat all field-cut edges with a suitable wood sealant if they are likely to be exposed to moisture near plumbing or external doorways.
Compliance & Performance
- Standard classification: EN 312 P5 moisture-resistant, structural grade particleboard for internal use.
- Service class: Rated for Service Class 1 (dry) and Service Class 2 (humid) environments.
- Fire rating: Standard Euroclass D performance; can be enhanced with appropriate fire-retardant treatments or underlays.
- Environmental status: E1 formaldehyde emission compliant for safe use in domestic and commercial interior living spaces.
- Important note: While P5 grade is moisture-resistant, it is not waterproof; all standing water must be removed immediately to prevent long-term thickness swelling.
