Live outage map for Wales
The map below shows incidents reported by users in real time across the UK, centred on Wales. Welsh outages cluster around two patterns: the South Wales Valleys and Cardiff suburbs lose power when Atlantic storms barrel up the Bristol Channel, while the mountainous Snowdonia and Mid Wales overhead network is the most exposed in the UK to lightning strikes, freezing rain and falling Sitka spruce.

What to do during a power cut in Wales
Check if it is just you
Look at neighbours and the street lights. If only your home is dark, check the consumer unit and reset any tripped switches. If the whole street is out, it is a network fault.
Call 105
Dial 105 — free, 24/7. Have your postcode ready. Ask for an estimated time of restoration (ETR) and a fault reference number.
Unplug electronics
Unplug TVs, computers, routers and games consoles to protect them from a power-surge when supply is restored. Leave one light on so you can tell when the power comes back.
Log the times
Note the exact start and end times. A cut over 24 hours in normal weather entitles you to £75 from your DNO under Ofgem's Guaranteed Standards. Severe weather has higher thresholds and a £2,000 cap.
The Selectra expert answers your questions on power cuts in Wales
Dial 105 (Free national fault line). It is free, 24/7 and routes you automatically to the right Distribution Network Operator for your postcode. Do not call your supplier (Octopus, British Gas, EDF…), they cannot fix a fault on the network.
Wales is split neatly between two DNOs: National Grid Electricity Distribution (the former Western Power Distribution) runs all 16 South Wales authorities from Pembrokeshire to Monmouthshire, while SP Energy Networks (Manweb) runs the six North Wales authorities from Anglesey to Wrexham. Dial 105 from anywhere in Wales to reach the right operator. Use the map and county finder below to identify your operator, or call 105 (or 03457 643 643 in Northern Ireland) and we will route you automatically.
Most cuts are restored within 1 to 3 hours. Rural single-feeder spurs can take 6 to 24 hours after major storms. Severe-weather events (Storm Arwen, Storm Babet) have caused multi-day cuts in remote Wales areas — these qualify for higher Ofgem compensation payments.
Yes, in most cases. Under Ofgem's Guaranteed Standards of Performance (GSOP), domestic customers receive £75 after 24h off in normal weather, then £40 per additional 12h up to £300. Severe-weather events have higher thresholds and a £2,000 cap. Payment is normally automatic from your DNO within 10 working days.
Join the Priority Services Register through your supplier. It is free and entitles you to advance notice of planned cuts, priority restoration, welfare calls and tailored support during outages. Anyone over 65, with a disability, on dialysis or oxygen, or with young children at home is eligible.
