Working with builder tip number 2
Get the quote in writing.
Have black on white the list of what is going to be done and the cost, inculding the VAT. Some builders add it after or just say that they had to get stuff that were not included, well they should write it down. Words are not enough. I learnt it the hard way. Get the quote in writing. Even if it is you ar the one writing it and the builder signing it.
