At Mill Hill Quarries Ltd we specialise in the supply of cornish roofing slate, building stone, garden products, slate flooring, slate chippings, and other quarry products to the domestic, construction and landscaping industry.

The construction industry's choice

Mill Hill Slate Quarries extract stone from the Upper Devonian Slate Beds to produce high quality, hand selected materials for use throughout the construction industry.

Aggregates and slate chippings are generated from offcuts making them a more sustainable and environmentally responsible choice.

Mill Hill and Trevillett slate building stones and floor tiles are dense, durable and versatile, for use in interior or exterior applications, they are available in blue, rustic or cutface finishes.

Cornish roofing slate is hand split by craftsmen at our Trevillett quarry near Tintagel, Cornwall, and extensively used in heritage repair projects and quality new builds.

Our Trevillett roofing slate is quarried from the Upper Delabole Slate Beds and is available in a wide range of sizes, including locally popular diminishing course randoms.

We strongly advise that orders placed are for the total amount required for the project. Due to high demand any requests for additional stone to finish a job will be treated as a seperate order processed according to the date placed.

Approx coverage per tonne is based on using the stone in a traditional way. Cutting/splitting the stone will result in extra wastage.
