Currently comparing Brazilian Black Riven Slate — calibrated, in every size.
We track every credible UK retailer for this tile, check their prices every morning, and tell you who's cheapest for your size, your postcode, and your project. Real prices, no nonsense. Black is the most popular colour in our wider slate tiles comparison — if you’re still deciding, start there to see every colour and finish.
We need three things to work out who's actually cheapest for you: the size you want, where you are, and how much you need. Adjust any of these and the comparison updates live.
We compare credible UK retailers selling this tile and check their prices every morning at 06:00 UTC so you don’t have to. Different retailers stock different sizes — we show you whoever has the size you’ve selected.
The price for one square metre of tile, with VAT included so you can compare like for like. Some retailers list prices without VAT (mostly the trade-focused ones); we add 20% so every number on the page is directly comparable.
Your room size × the price per m² with VAT included. Worth noting: most tilers allow 10–15% extra for cuts and breakages — particularly important for complex patterns like herringbone or diagonal laying. Order a bit more than your raw floor area.
Project total plus each retailer’s delivery cost to your postcode. Stone is heavy, so it almost always ships on a pallet. We use real haulier rates by UK region. At roughly 28 kg/m², 10mm slate fits about 35 m² per pallet (1000 kg maximum) — larger orders need additional pallets, which is why delivery cost scales with project size.
Prices update once a day at 06:00 UTC, fully automated. If a retailer changes their site and we miss it, we usually catch up within 24 hours. Spotted something that looks wrong? Let us know and we’ll have a look.
We currently hold live prices for 36 / 36 retailer-and-size combinations. Not every retailer stocks every size, so some combinations stay empty until a retailer adds that size — the figure updates itself as our coverage grows.
