Heat pump and hot water tank installation: Each time a EPC improvements representative attended our property for the various surveys they had the wrong layout and one which we'd never discussed. We needed our loft joists to be strengthened to support the new water tank and waited several months for EPC to attend to let us know where the tank would fit so we could strengthen the structure, only for the surveyor to again have the wrong information with him. We later paid a deposit which we were told was to secure the heat pump kit we'd asked for as equipment was becoming more difficult to source, which we paid. When the install was due several months later and only 2 weeks before our green homes grant voucher was due to expire we found out that EPC hadn’t used our deposit money to buy the equipment we’d paid for, and could no longer get the kit we wanted, and only lesser smaller products were now available. We didn't want to compromise on the system and had lost confidence in the EPC management to deliver the project we asked for and requested our deposit back at the end of November 21 and abandoned our chance to use the Green Homes grant voucher. Now end of January 22 we have only just received our deposit back following the senior managements failure to communicate. We recommend you go elsewhere to a more reputable company.
