Excellent service — delivery was very quick, and the quality and sizes of the slate were far superior to those of local garden centres. I would not hesitate to recommend Celtic Slate & Stone. A great supplier of natural British stone.
Very good quality stone, exactly as described on the website and nice big pieces, much better value than buying from the garden centre. Delivery was quick and exactly on schedule too. Thanks Steffan!
So pleased to have found Steffan at Celtic Slate & Stone — the only place willing to supply a smaller amount of rocks at a very fair price. Very helpful communication and a lovely selection of sizes. Very recommended.
