UK energy lower warning as 41C excessive warmth might push grid ‘to breaking level’
The UK is set to be hit by a new heatwave within the week, with temperatures expected to soar to 41C in some areas – and experts warn the National Grid could face breaking point, risking widespread power cuts

The UK has been cautioned about the possibility of power outages as temperatures of 41C are predicted to strike the nation in a fresh heatwave that could stretch the grid to ‘breaking point’.
Weather experts suggest that the UK might witness its hottest day on record as a new heatwave is anticipated within the week, with regions in the south east of England reaching peaks of 41C.
Multiple counties are also expected to swelter in 40C conditions, with another bout of disruption likely to wreak havoc as services surpass demand thresholds and scorching temperatures affect daily routines.
The latest spell of extreme heat resulted in numerous power failures across London and Somerset, with a staggering 35 areas receiving alerts about potential electricity loss.
The Met Office cautioned that the heat would create a risk of “failure” leading to a “probable loss of power” and other vital services, including water, electricity, gas or mobile phone networks.
With temperatures set to surpass recent peaks, this issue is only anticipated to worsen.
According to infrastructure specialist Taco Engelaar, as energy consumption rises during extreme heat, certain regions will “push the grid to breaking point – disrupting supply and leaving homes without power”.
Engelaar continued: “In 2022’s 40C heatwave, thousands of homes lost power after transformers failed and conductors drooped.”
When temperatures climbed to an all-time record four years ago, 15,000 households in England were left without electricity. Following last week’s disruption, should temperatures soar above 40C, thousands of households will face a significant risk of power cuts.
Engelaar continued: “In high temperatures, sagging power lines can come into contact with dry vegetation, sparking wildfires.
“These fires don’t just pose a threat to communities – they can severely damage infrastructure, leading to extended outages. And in some cases, utilities are forced to shut off parts of the network pre-emptively to reduce the risk.
“Once damage occurs, safety concerns mean repairs can be slower in extreme heat, increasing the length of localised blackouts.”
Ahead of the scorching heatwave, Brits are urged to prepare for potential power loss, including assembling an emergency kit.
This encompasses torches, essential medical documentation and attempting to ensure devices are fully charged before any crises.
The Met Office also encourages people to support vulnerable individuals, including elderly relatives and neighbours.
