When will I need to upgrade my boiler for hydrogen?
Over the next 5 years hydrogen will be added to the gas grid, but that does not mean that you need to have a hydrogen-ready boiler straight away. Modern boilers are able to accommodate up to 20% hydrogen which will be the first phase of the transition. It is likely to take around 10 years for industry to achieve adequate hydrogen production, storage and distribution levels to make any higher level a realistic option.
