We need to decide by Thursday whether to upgrade our laminate worktops to silestone in our newbuild property. I assume we've been given an inflated price for the convenience of having it done before we move in but I have no idea if or by how much.
Is anyone able to share how much they paid for their silestone worktops, please? It is a small kitchen area with a breakfast bar (pictured) and the quote comes to nearly £5k. I wouldn't normally consider it but I just love the sparkle of the Stellar Blanco Silestone. 
Assuming it is overpriced, does anyone know how easy it is to replace a laminate worktop with a silestone one after it's been installed?
Thank you!
