UK Blackouts: The Ultimate Guide
Since the 1970s, when coal miners and railway workers went on strike, there hasn’t been an organised blackout in the UK. But with cold weather and gas shortages this winter, a potential blackout may become a reality. Official Government documents reveal a potential plan for power blackouts during three-hour intervals this winter if gas imports from Russia are reduced. This scenario could affect different regions of the UK, so it’s essential to prepare as best you can.

UK Blackouts: The History
UK blackouts a re relatively uncommon and usually, a localised issue that can be resolved quickly. However, sometimes power cuts can have much greater effects and cause major disruption across the country. One of Britain’s most notorious blackouts occurred in 1972, when miners went on strike over wages and negotiations with Edward Heath’s Conservative government broke down. A state of emergency was declared as electricity supplies ran low due to shortages. Due to this ban, power was restricted for private households and businesses that weren’t considered essential services. Many families were left having to learn how to live without electricity, cooking by candlelight or using paraffin lamps for illumination in their homes.
Estimates suggest more than 1.15 million people were cut off from the power grid during this six-week strike – some even left without lights! The strikes had a devastating impact on the country’s economy and caused multiple disruptions. Tens of thousands of coal miners found themselves out of work while rising inflation caused by the strike further reduced wages.
Heath responded by instituting a three-day working week. While this may have seemed like a good idea at the time, many families struggled to make ends meet. Electric Insights reports that engineers in the UK are encouraged to create innovative solutions for the UK’s electricity network to prevent blackouts as much as possible. It’s an especially critical time for the industry, with an increasing need for backup power systems and increased resilience when dealing with severe weather events. Business Secretary Kwasi Kwarteng is confident the country won’t suffer any major disruption this winter. He adds that businesses can take steps to avoid such incidents, such as installing generators.
UK Blackouts: How is it Planned?
UK Blackouts: Load Blocks
UK blackouts are electricity cuts that occur when Britain’s supply system overwhelms, and there isn’t enough energy to meet demand . They can happen due to an imbalance between the demand and supply of electricity – or if there isn’t enough gas available for running generators which provide electricity. A variety of different suppliers manage Britain’s electricity supply. Each divides its distribution network into 18 ‘load blocks,’ similar to postcodes in operation. Each load block is identified by a letter between A and U. Occasionally, F, I, and O may indicate which block you belong in. You can check your load block letter online using your postcode or find it on your energy bill.
During blackouts, power is divided evenly among all energy consumers within a load block in an organised and fair fashion. This process, known as ‘power-sharing rota’, helps reduce the time you are without power. Under this plan, you will be alerted before any three-hour blocks when your electricity will be disconnected. A copy of the ‘load block letter chart’ is also sent to you on which days your load block will experience three-hour blackouts. If you are worried about blackouts, having a backup power source to keep essential equipment running during an outage is wise.
Keep your mobile phone charged and utilise a portable battery bank to stay productive when your main source of electricity is interrupted. However, some vulnerable people who rely on medical equipment may not have these backups and could experience extended periods without electricity. If this applies to you, speak with your doctor or hospital immediately and make sure you have a suitable battery for your device to continue receiving treatment.
Under the Electrical Supply Emergency Code , the National Grid has a procedure that ensures equitable power distribution throughout the UK during an energy crisis. This includes designating certain sites as ‘protected sites’ exempt from emergency planned power cuts – such as air traffic control centres and major hospitals with accident and emergency departments.
UK Blackouts: Protected Sites
Recent power cuts and blackouts have demonstrated how disruptive blackouts can be for businesses. Not only does it disrupt supply chains and operations, but businesses must also manage various operational risks. Energy blackouts c an have a different impact on different businesses, depending on their location and model. Office-based businesses must ensure their IT systems can stay operational even remotely. In contrast, at-home workers must ensure their computers remain powered up so they can work remotely. However, some industries cannot function without electricity.
Examples include :
Hospitals,
Pharmaceutical firms producing vaccines for pandemics and
Air traffic control centres.
Hospitals and other essential facilities may be safeguarded against rolling blackouts by the ENA if they’re listed as “protected sites”.
This list includes water and sewer installations, some ports, and financial services.
If a business is identified as an affected site, it must communicate its request to its network operator in advance. These businesses must reduce their consumption in line with three-hour rota disconnections and keep records of their usage for government oversight. On the most severe blackouts, these sites will be forced to reduce their energy use further to protect their infrastructure.
In these times, they may need to use ‘backup generators’ for continued operation.
UK Blackouts: How to Prepare
Generators can run off various fuels but are usually composed of propane or natural gas. Unfortunately, they require time to refuel, so they may not be available during an emergency. Due to the potential blackouts, many seek products to prepare for them. Reddit threads have seen an uptick in people offering suggestions on how to stay warm and safe during an outage, including bio-ethanol fires, USB-powered electric blankets, dry pre-packaged meals, water filters and plumbing supplies . Though these products are not the only options for consumers prepping for a potential blackout, they provide an excellent starting point for emergency preparedness.
It should be noted that the energy crisis will likely last only a few days, so that these items won’t guarantee complete protection from power outages. Contingency Planning At present, businesses and the UK economy face several obstacles that could impact operations. Fortunately, there are steps you can take to minimise any negative repercussions from power outages – no matter how big or small.
Create a contingency plan for an impending blackout to prepare beforehand and guarantee your employees can continue working safely and securely during the period. Furthermore, this will help identify any health or safety issues arising from the blackouts so they can be addressed beforehand.
Businesses must understand their processes and systems and how they collaborate with other parties in the supply chain. Doing this helps avoid any miscommunication or issues during a blackout.
UK Blackouts: Your Business
Employers must ensure they comprehend the potential repercussions of a UK blackout, especially for staff working from home and isolated areas. Employees will likely feel anxious and worried about how this will affect their work and personal life, so make sure they know your plans and communicate them. A blackout can wreak havoc on businesses, staff members, and the general public. For instance, it could prevent access to underground car parks or make it unsafe to enter offices that rely on electricity for their doors. However, you can do to help safeguard your business against a UK blackout. Some of these steps include contacting building insurers or contacting your electricity supplier.
Furthermore, performing a ‘black building’ test to see what would happen if all power was suddenly cut off in your workplace is an invaluable way of discovering what would transpire if everything went dark. Although it is unlikely there will be any blackouts this winter, having a contingency plan in place is essential for any eventuality that may occur.
