SAP 10 and Hydrogens Future Role

The future of the UK new build and existing house market could see the use of hydrogen boilers playing a large part. However, despite this, the use of Hydrogen will not be a selectable option under SAP 10 and will not be selectable until the subsequent regulation is due in 2025.

 Several manufacturers have announced they are working on a Hydrogen boiler, with the first few boilers expected in 2025. The initial boiler will be ‘Hydrogen ready boiler’ similar to the initial HD ready television however, these boilers could burn mains gas and eventually Hydrogen.

It is expected that as much of 35% of the UK’s energy consumption by 2050 will be Hydrogen; however, the use of Hydrogen on the existing building stock is not expected to be announced until after 2026 after the trial on the use of the fuel is concluded. If the trial proves to be a success, the government is hopeful of establishing an entirely hydrogen town by the end of 2030 to monitor the success and impact of changing people’s lives.

The hydrogen potential is also expected to be backed up with a new scrappage scheme for boilers with incentives as high as £7,000 to the homeowner to switch from mains gas to low carbon alternative, which would also include heat pumps. The new scheme will be called ‘Clean heat Grant’ and it has an initial budget of £100 million, which could be increased if required and will be launched in April 2022.

All the above items covered in the article are expected to be announced at the November’s COP26 meeting being held in Glasgow; however, these times may change. The government is also considering a complete ban on gas boilers by 2035
