We had our loft conversion and kitchen extension both done by CFD. We found that they were extremely professional from the start with clear communication, advice and pricing from Mark and Peter. All of the work was completed to a high standard with disruption and mess kept to a minimum. Special mention to James for the loft and Graham for the kitchen for the quality of their work. We’d definitely use them again and highly recommend them.

Cox Format built our single-storey ground floor extension, incorporating a new en suite and dining area and preparation of the existing kitchen space for new units. As well as extensive construction, the works included a new boiler and radiators, updated electrics and the installation of lantern skylights. In addition, they refurbished our upstairs bathroom, which involved a new floor, re-routing drainage pipes and the digging of a new manhole. Their costing was fair for the quality of work provided and included the provision of drawings and the obtaining of planning permission. Where potential problems arose, they were proactive in recommending solutions and quick to reconsult both the architects and structural engineer to produce the desired result. Their workers were polite, punctual and skilled, with a clear contact structure in place, involving a knowledgeable foreman and efficient, friendly project manager. I would highly recommend them.

Highly recommended I am delighted with the transformation of my home, which involved much more than a loft conversion, adding complexity to the project. Communication was excellent from the pre-contract stage to completion. I appreciate the time taken before building started, to work through the plans in detail (design as well as costs). The foreman and his team were friendly, reliable, hardworking and efficient, with the work completed on time. His communication with me, my neighbours and suppliers was always timely, relevant and helpful. I am very happy with the quality of work and would confidently entrust CFD to deliver other home improvements I am planning.

As well as a loft conversion, Cox Format also remodelled the middle floor of our house. Communication from start to finish was excellent. James was fantastic managing the works and was always available and willing to offer time to talk through different aspects of the job. He has a great friendly and professional team who were ready to go at 0730 and worked through to 4pm. The work is of very high quality and it has transformed our house and the space we live in. Our home is our most valuable asset and we're pleased and grateful that we put our trust in Cox Format.
