Easy to order on-line and was given the delivery date. Order arrived midday and was exactly as expected. Price was competitive and the whole experience was excellent. I will definitely consider further purchases from Gravel master.

Great service, quick delivery and professional staff.


I ordered 2 bulk bags of 20mm green slate chippings from the website on Sunday. I was contacted on Monday to confirm delivery was ok for Wednesday. Delivery was made on Wednesday morning. Quality excellent. Very impressed with the ease of the process. Will use Gravelmaster again.
