Energy expert comments on blackout concerns and how Brits can prepare

Go.Compare’s energy expert has commented on Brits' blackout concerns and shared the simple steps they can take to prepare, amid reports that the UK’s electricity system came under pressure during June's extreme heat.*

The grid has faced several challenges during the extreme heat, including increased demand from cooling appliances, lower wind generation and reduced output from some power stations.** 

Gareth Kloet, expert at Go.Compare Energy, said: “Blackouts are still unlikely, and it is important not to panic. Ofgem has stated that it remains confident in Britain's security of supply, and that it is investigating reports of the system coming under stress during the heat event.

“That said, extreme weather can put extra pressure on the system, and households are understandably looking for reassurance. The sensible approach is to be prepared without being alarmed. A few practical steps can help you stay comfortable, keep costs under control and make sure you are not caught out if there is power disruption for any reason.

“If you rely on electricity for medical equipment, mobility support, or vital heating, cooling or communications, you should contact your supplier and ask to be added to the Priority Services Register. It is also worth keeping a power bank charged for your phone, a list of key phone numbers written down somewhere you can access without the internet, and knowing where a torch is.”

Go.Compare's practical preparation tips for households

• Check your supplier's emergency advice: Your energy supplier and network operator should explain what to do if you experience a power cut.
• Keep essentials charged: Charge phones, power banks and any essential battery-powered devices during periods of extreme weather.
• Keep a torch handy: Avoid relying on candles where possible, and make sure batteries are working.
• Plan for vulnerable household members: If someone in your home depends on electricity for medical or mobility equipment, speak to your supplier about support through the Priority Services Register.
• Manage cooling costs: Fans and portable air conditioning units can increase usage during heatwaves, so check how often you are using them and keep an eye on your tariff's unit rates.
• Know who to call: Save your supplier's contact details and the national power cut number, 105, somewhere offline.

Gareth adds: “Preparation does not need to mean stockpiling or making big purchases. For most households, it is about small checks: knowing your energy supplier's advice, keeping devices charged, and making sure anyone with extra needs is registered for the right support.

“It is also worth remembering to check your energy usage during hot weather. A fan or air con unit might feel like a small extra, but if it is running for hours every day, the cost can add up. You can get an understanding of how much common household appliances cost using our calculator. Checking your tariff, your unit rates and your standing charges can help you get an idea of what your summer energy habits are likely to cost.”
