FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.

Fire Performance You Can Rely On
Rated Euroclass A1, Gyproc MultiBoard offers dependable fire resistance in high-risk zones. It supports fire-rated enclosures, steel encasements, and drylining in sensitive environments. The 12.5mm board contributes to passive fire protection with minimal build-up height.
You can install this board in commercial or domestic properties where fire safety is essential. It’s a strong choice for wall linings, partitions, and ceilings in stairwells, plant rooms, or communal areas.
Tough Surface, Clean Finish
Gyproc MultiBoard is reinforced with glass fibres. This boosts impact resistance in high-traffic areas. The paperless finish creates a smoother surface, saving you time on skimming. It accepts paint, tiles, or wallpaper directly.
Handles Humid and Tough Spaces
MultiBoard performs in moisture-prone areas like bathrooms and soffits. It resists decay and holds its shape even with changes in humidity. You can use it in semi-exposed locations where standard plasterboard would fail.
Flexible Installation, Quick Setup
The board curves down to a 2.7m radius and cuts cleanly with standard tools. That makes it suitable for curved installations, custom ducting, and detail work. Lightweight and simple to fix, it suits quick builds and refurbishments.
Multi-Performance Plasterboard for Complex Builds
You can rely on British Gypsum Gyproc MultiBoard for fire, moisture, and impact resistance all in one. Whether you’re lining ducting, boxing in steels, or fitting soffits, this board handles it all.
