Since our inception, we have continued to build our business on our approach to the customer.

Our team of fully-qualified engineers provides quality and value engineering from design to commissioning of commercial heating, plumbing, cooling and ventilation services.

We work on a sub-contract or direct-to-the-client basis.

Our air conditioning, heating and ventilation systems are located in offices, supermarkets, hotels, restaurants and industrial premises, such as factories – not just in Lancashire, where our office is located, but in cities across the UK such as Edinburgh, Manchester, Birmingham, London, and Liverpool.

We provide a comprehensive service and maintenance package following all our installations in order to ensure that our customers get the best out of their investment.

We also provide service and maintenance packages on existing mechanical and air conditioning systems for those customers looking for a new supplier.
