Hi all, asking for my brother. He got an extension there done over the last 5/6 months and every worker the contractor has hired has has hooked onto his ESB and his bill is now an additional 400/500 Euros over that period of time. Now he would of let this go but the builder is trying to add additional costs on the slightest bit of extra work such as hanging a light and trying to get more money for elements of the job that were documented as being part of the job. Is he in his rights to ask the builder to cover the cost of the additional ESB which is definitely due to the works completed by the builder and he can prove it due to the comparison in units used from the same period last year? There was nothing in the contract about them using his ESB.
