Delivery times
We aim to deliver in-stock mainland orders in 1–3 working days, allowing up to five working days, subject to availability and delivery access. We will contact you to arrange delivery. Any different lead time will be confirmed before ordering.
Pre-orders are delivered after the stated warehouse arrival date, which is an estimate and may change. A preferred delivery day is a request for our team to confirm, not a guaranteed booking.
Sample delivery
All samples are sent free by Royal Mail Tracked 24, separately from full-size materials. Delivery is typically 24–48 hours after collection, rather than a guaranteed arrival time. Tracking details are emailed once collected.
Order before 3pm Monday–Thursday for that day’s sample collection. Orders placed later are prepared for the next available collection.
Eligible small fixings also receive free Royal Mail Tracked 24 delivery. For mixed baskets containing boards or larger materials, the applicable project delivery charge remains payable; samples and eligible fixings do not add an extra delivery charge.
Mixed orders and product lead times
We aim to deliver mixed orders together. Items may be packed separately, and a product with a longer stated lead time may affect your delivery date. Check each product page for availability.
Container or manufacturer-direct orders may have separate lead times and delivery fees. Please contact our team before ordering.
Access and unloading
Please tell us about narrow lanes, restricted access or other site constraints when ordering. This helps us plan your delivery.
Large or heavy orders may arrive on a pallet; pallet deliveries are usually kerbside. We will contact you if assistance is needed for unloading.
Collect from our Manchester warehouse
Collection is usually ready within 24 hours. You will receive an email after placing your order. Please wait for confirmation that your items are ready before travelling.
