New build renewable heating experts


HBS Mechanical provides expert new-build heating services, including renewable heating design, supply and installation for housebuilders as they begin planning for full compliance with Part L and the Future Homes Standard.

We combine our experience in traditional forms of heating, plumbing and electrical works with our expertise in renewable energy technologies to provide a full-service solution that can be tailored to meet your specific project needs in line with new regulations.

For housing developers, air source heat pumps are capable of operating up to 300% efficiency, so are incredibly efficient. They are proven to help reduce carbon emissions and meet current and future carbon reduction targets on new build housing developments.

Installing an air source heat pump system will not only significantly reduce residents’ energy bills it will also provide protection from future energy price rises. In comparison, a traditional gas boiler heating system is only 90% efficient.

Our team of renewable heating specialists have a wealth of experience in installing air source heat pumps on large residential new build housing schemes. So, you have peace of mind that we can achieve your project’s renewable energy requirements within specification and in the most cost-effective way.

We provide a professional plumbing and heating service to the new build private and social housing sector, delivering industry leading results and operational excellence for all our clients.
