Despite Britain’s energy system creaking under the strain, it’s actually extremely reliable. If you ignore freak weather events, it’s rare to experience a power cut for no good reason and brownouts are now a thing of the past.
But factor in extreme weather and the picture changes completely. Storms, high winds, flooding, and ice can leave entire regions in the dark.
When that happens, what are your rights? Are you entitled to compensation, and if so, how much?
How the UK electricity network works
One of the first things to understand is that your electricity supplier (the company you pay bills to) is not responsible for outages.
It’s your distribution network operator (DNO) that manages the wires, substations and poles that deliver electricity to your home.
There are six main DNOs covering England, Scotland, and Wales:
- Electricity North West
- Northern Powergrid
- Scottish and Southern Electricity Networks (SSEN)
- Scottish Power Energy Networks
- UK Power Networks
- Western Power Distribution
Each of them is regulated by Ofgem, which sets the standards for reliability and compensation.
What counts as a “weather-related” power cut
A weather-related cut is an outage caused by conditions beyond the operator’s control, such as:
- Storm damage from falling trees or debris
- Flooding of substations or power lines
- High winds or snow damaging infrastructure
- Lightning strikes or ice causing faults
Planned maintenance or faults unrelated to weather don’t qualify for the same compensation rules.
Changes to energy rules for storms
Rule changes introduced on 1 September 2023 strengthened consumer rights after high-profile failures such as Storm Arwen in 2021, when around 40,000 homes in northern England and Scotland lost power for more than 72 hours.
The updated rules:
- Place the responsibility on the DNO to issue compensation automatically
- Apply to all DNOs across Great Britain
- Increase the maximum payout from £700 to £2,000
- Extend the threshold times for compensation, depending on storm category
- Require operators to pay by bank transfer as well as cheque
Your rights if you suffer a power cut due to weather
If your power is cut due to a storm, here’s what you can expect:
- Category 1 storm: If power is out for 24 hours or more, you’ll be entitled to £80, plus £40 for every additional 6-hour period without supply.
- Category 2 storm: You must be without power for at least 48 hours before compensation begins. After that, the same £80 plus £40 per 6 hours applies.
- Maximum payment: Up to £2,000 per household (per meter).
Payments should be made automatically. Your network operator will contact you to confirm details and arrange payment.
Storm compensation rules (2025)
| Storm category | Minimum outage duration before compensation | Initial payment | Ongoing payment | Maximum payment |
|---|---|---|---|---|
| Category 1 (less severe storm) | 24 hours | £80 | £40 for every additional 6 hours without power | £2,000 |
| Category 2 (more severe storm) | 48 hours | £80 | £40 for every additional 6 hours without power | £2,000 |
If you aren’t contacted within a reasonable period, check your DNO’s website. If they refuse or delay, escalate to Citizens Advice or the Energy Ombudsman.
Extra protections for vulnerable customers
If you rely on electricity for medical equipment, refrigerated medicines, or mobility aids, you should join your DNO’s Priority Services Register.
Benefits include:
- Advance notice of planned outages
- Extra support during emergencies (e.g. hot meals, alternative power sources)
- Faster response times where possible
This doesn’t guarantee higher compensation, but it gives you stronger practical protection during a blackout.
How to prepare for extreme weather outages
While you can’t prevent a storm, you can reduce the disruption:
- Keep a blackout kit with torches, batteries, candles, and power banks
- Charge devices when severe weather is forecast
- Store some non-perishable food and bottled water
- Use surge protectors or a UPS for critical equipment
- Register for Met Office weather alerts and your DNO’s outage alerts
- If you’re medically dependent on electricity, have a backup plan in place

What to do if you’re not compensated
If you think you qualify for compensation but aren’t contacted:
- Visit your network operator’s website to check live outage information.
- Contact them directly with your supply number (found on your bill).
- If the operator refuses or delays, escalate to Citizens Advice.
- As a final step, take the case to the Energy Ombudsman, who can make binding decisions.
Keep records of outage times, communications, and any costs incurred, as this may strengthen your case.

Power cut due to extreme weather FAQs
Do I always get compensation automatically if my power goes out in a storm?
Yes, if the outage meets the minimum duration thresholds. Payments should be automatic, but if you hear nothing within a few weeks, contact your DNO.
What is the difference between a category 1 and category 2 storm?
These categories are used by operators to measure storm severity. A category 1 event triggers compensation after 24 hours without power, while a category 2 requires 48 hours. Classification depends on wind speeds, storm damage, and number of faults reported.
How much will I receive if the outage lasts several days?
You’ll receive £80 once the threshold is met, plus £40 for every 6-hour block you remain without power. The maximum you can receive is £2,000 per incident.
Do these rules apply in Northern Ireland?
No. Northern Ireland has its own system operated by NIE Networks. Check directly with them for local compensation rules.
What if I rely on electricity for medical equipment?
You should register with your network operator’s Priority Services Register. This ensures they know you’re a priority in emergencies and may provide extra support, though standard compensation rules still apply.
