I was given a quote by a builder for work to be carried out, I never received nothing in writing and I haven’t seen any receipts for any materials, the final bill is an extra £1400 what I was previously quoted
Sorry to hear your having problems with your quote.I would argue the Extra £1400.I always give quotes with materials stated to avoid problems later on .I would ask for a invoice with all materials listed and Extra work undertaken.Always ask for confirmation by email or text on quotes, then it's all covered and you can go back to builder.Dont feel intimidated you have the right to question Extra payments.
this is a common situation in the building world, as things change whilst doing the work. Sometimes extra materials are needed, which means, obviously it will take longer to install.
There for it is likely to cost more labour also.
This can really mount up, and the contractor should have informed you of any additional costs forthcoming.
Ending on a happy note; ‘Are you happy with your job’?
