As part of our commitment to service quality, Warmworks manages a network of more than 20 registered sub-contractors across the country who help us provide a first-class service to our customers. Before any organisation can be approved as a registered Warmworks sub-contractor, they must satisfy our industry-leading standards on quality, compliance and accreditations.

Once an initial survey has been carried out in our customers’ homes, we will assign a trusted local sub-contractor to install the agreed energy efficiency improvements. This process is expertly managed by our team, working closely with our supply chain to ensure a smooth installation process. Each sub-contractor is continually assessed by a specially-designed performance management system. This is to reassure our customers that they will receive high quality workmanship, and that the people coming into their home are professional, trustworthy and able to deal quickly with any questions or concerns that may arise.
