NAO warning on grid upgrades
The National Audit Office has flagged that without faster electricity grid upgrades, consumers could face an extra £7.8 billion in annual costs by 2030. The bill stems from wasted renewable power that the current network cannot move efficiently, plus the need for more expensive backup generation.

These added costs would land on every household through higher system charges. The warning comes as the UK tries to shift more homes to electric heating and EVs, both of which increase demand on the same ageing wires. Our recent look at how simple changes around the home can cut heating waste shows small steps still help while bigger fixes lag.
