From the quarry to your garden
★★★★★ 5.0 · Every review verified
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.

Rockery stone for gardens and landscaping
We have two types of stone available: Welsh slate, and glacial stone. The slate is sourced direct from our quarry, while the glacial stone is from our local surrounding area of Snowdonia in North Wales. Formed by nature over millions of years, our rockery stone will add a natural timeless look to your garden.
Larger pieces work well as feature stones or as edging stones. Our large glacial stones being more boulder shaped are often used as parking barriers. Both the slate and the glacial stone are extrememly durbale and perfect for low-maintenance gardens. They will not deteriorate over time and will last a lifetime.
Rockery stone for ponds and water features
The same hand-selected stone that builds garden rockeries works equally well in and around water. The colours will darken / enhance in contact with water.

How quickly will my order be delivered?
How is my order delivered?
1. There needs to be access for a delivery lorry to your address.
2. The delivery company will unload roadside. The pallet(s) can then be moved onto your property using a pallet pump truck - this will only work on hard ground (not on grass or gravel), that is relatively level, and free from steps. If there is no pallet pump truck access onto your property the pallet(s) will be left kerbside.
3. If there is easy pallet pump truck access onto your property then you don't need to be at home on the day of delivery. If the order needs to be left kerbside then you will need to be available on the day.
Feel free to contact us if you would like us to check the suitability of delivery to your address.
