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.

We couldn't be more delighted with the flat pond edging stones we bought. They make the perfect lawn-to-border divide and surround to our pond project. They slot together in a suitably random but organised manner. We couldn't have asked for anything better.

Celtic Slate and Stone delivered an excellent product, amazing customer service and exactly what was promised. Steffan must have hand-picked many of the pieces of slate for my project. Unbelievable value for money.

Great product and service. I ordered a bulk bag of slate chippings for my garden. Lovely product, solid chunks of slate, unlike the flimsy small chips I've seen in neighbours' gardens. Delivered within a week.
