Recommendation 23

We recognise there is a mix of evidence on the role hydrogen can play in the decarbonisation of domestic heating and there is still a substantial amount of work being done that will determine its eventual use. However, in the meantime, the evidence in favour of mandating hydrogen-ready boilers in all suitable properties at the earliest opportunity is convincing, no matter what decision is eventually made on the blend of hydrogen in the system, or whether the system becomes a 100% hydrogen gas network. Assurances from the largest four boiler manufacturers indicate that hydrogen-ready boilers will be the same price as standard boilers, removing a key obstacle in rolling them out across UK households. It means millions more properties would be ready and able to switch to hydrogen sooner rather than later and with lower conversion costs, if required, should the UK Government opt for a low carbon hydrogen-based gas network.
