I was considering getting offcuts of Silestone for my worktops and had been given a good price (around £1,400 inc VAT) but would have had limited choice of colours. Instead we've decided to go with a group 1 colour of our choice, plus upstands, window sill and splashback. We're getting 2 lengths totalling 5metres. With cutouts and fitting we've been quoted £1,900 inc VAT. Is this a good price or should I shop around for a cheaper Quartz (e.g. Lunastone)?
