We are highly committed to providing low cost deliveries to our customers which is why we aim to hold the majority of our products in stock, however due to the vast amount of products available this isn’t always possible, so there are a small range of products that we are unable to stock and have to be sent direct from the manufacturers, which therefore means different delivery charges may apply as standard.


Over the past year or so there have been extensive manufacturer lead times which caused a Nationwide shortage on concrete and clay products. Whilst this issue has improved greatly and items are generally now readily available, there are still some products with lead times and we would suggest that you call us on 0330 123 1885 or email [email protected] to check stock in your area before placing an order.
