I've just had invoice from builder that's 10% on top of original quote, so £1000+ extra
We've queried it with him as was told there were no extras when we asked if there were going to be - throughout project. The reasons for extras seem unfair, ie extra floor tiles when he knew how big the floor was at the start, putting a shelf up we said we'd be happy to do, a different style plug socket (same price online).
The flooring is the biggest extra and it's doubly annoying as we went for a cheaper tile to keep in budget, his addition makes it more expensive than our first choice of flooring.
I'm furious. Aibu not to pay for the extra tiles?
