Questions before you order
Is limestone suitable for a wood-burning stove?
Yes. Limestone is non-combustible and a standard UK hearth material. Always follow your stove maker's and installer's guidance.
Can my installer deal with you directly?
Yes. Add their name and number when you order and we'll arrange the delivery details with them.
Can I add other slabs to the same order?
Yes. Extra slabs pay our normal pallet charge once, on top of the set.
Can I collect instead?
Yes, free from Milton Keynes. The set price is the same.
Can I see the stone first?
Yes. Order up to 2 samples for £5 delivery.
What if a slab cracks?
If either slab cracks within 14 days of delivery, provided it was installed in that window, we replace it free.
