UK | New laws passed to bolster energy security and deliver net zero

The biggest piece of energy legislation in the UK’s history has become law today (Thursday 26 October), laying the foundations for an energy system fit for the future.  

The Energy Act 2023 has received Royal Assent and will transform the UK’s energy system by strengthening energy security, supporting the delivery of net zero and ensuring household bills are affordable in the long-term. 

The Act will deliver a more efficient energy system in the long-term, helping to keep energy costs low. It will do this by increasing competition in Great Britain’s onshore electricity networks, through a new tender process – reducing costs for network operation and development. This new model is expected to save consumers up to £1 billion off their energy bills by 2050.  

A specific merger regime for energy networks will also be created under the Competition and Markets Authority. This will minimise the risk of mergers between energy network companies having detrimental effects on consumers and is estimated to save households up to £420 million over the next decade.
