We offer all bricks with a tail lift offloading service, Please familiarise yourself with the information below.
Crane offloading is available as a premium service for some bricks.
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.

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.
For deliveries of less than 6 packs then Taillift offloading is normally a more cost effective option
