It can be done, but it’s messy. You’d have to ring around and ask.

Thank you Daisy. I could only find one company online who does this, and it’s really hard to contact them. They’re fully booked all the time. If you have any suggestions on who I could call, I would really appreciate it.

I've no idea if they can do this, but i''ve just had quartz worktops installed by The Marble Group (i think from Hatfield) and I highly recommend them

Thank you so much, cushioncover. I’ll ask them if they could help.

Another place worth trying is Marble City in Wandsworth/Battersea area - they are really helpful.
