The cost of a commercial boiler installation depends on the size and type of boiler required, the complexity of the existing system, the building type, and any associated pipework or flue modifications needed. Commercial boiler installations vary significantly in cost – a smaller office system will cost considerably less than a large industrial installation. PES provides free site surveys and detailed written quotations before any work begins. Call 0203 439 9474 to arrange an assessment.
