By following these guidelines, you can reduce the risk of electrical accidents and keep your home safe.

Remember, in an emergency, call 111. If in doubt, give MainPower a call on 0800 30 90 80 for advice.

Electricity safety warnings

Warning signs of electrical problems

If you notice any of these warning signs, contact your landlord or a licensed electrician immediately.

Remember: Always treat all electrical equipment as live to ensure your safety. 

Safety for kids

It’s important for children to learn about electrical safety from an early age. Teach your children to stay away from power lines and trees that are close to them. Ensure they can recognise standard electrical warning signs and understand the importance of keeping their distance.

Energy Explorers is an activity book created by MainPower to help kids learn about electricity. It is packed with fun puzzles, engaging activities, and colourful illustrations that make learning about energy exciting and fun. 

Check out our Energy Explorers activity book here.

Outdoor electrical safety

Take extra precautions around electricity when working or playing outdoors. Be aware of overhead power lines and underground cables, especially when using ladders, pruning trees, or digging. Before starting any work that could involve power lines, such as painting, trimming trees, or replacing roofing, contact MainPower to discuss safety measures or disconnecting the power.

Never touch overhead power lines, underground cables, or any bare conductors connecting them to your home, as this could be fatal.

Outdoor safety tips

DIY electrical work

While DIY electrical work might seem like a cost-effective solution, it can be dangerous if not done correctly. Homeowners are allowed to carry out certain electrical tasks, provided they comply with national standards. However, it’s safer to hire a licensed electrician to prevent risks such as electric shock or fire.

Hot water load testing under way ahead of winter

Until mid‑April, we’re working closely with retailers to carry out hot water load testing as we prepare our network for the coming winter season.

These tests run for a couple of hours each day, Monday to Friday, with no testing taking place over weekends. Because each test window is relatively short, customers are unlikely to notice any changes to their hot water supply.

The purpose of this work is to help us better understand how much controllable load is available during the summer months. Gaining accurate insights now means we can model customer savings more effectively by reducing system load at peak times. It also helps us assess whether this load flexibility could assist Transpower in deferring an upcoming local transmission upgrade.

This testing is an important part of ensuring a resilient, efficient network that supports our community.
