Why have energy prices gone up?

It’s gotten more expensive for providers to buy energy, which has led to it costing more for us to power our homes and businesses.

How can I reduce how much energy I use?

You can cut back on your energy usage by turning appliances off standby, lowering the temperature of your heating and washing machine, as well as being careful about how much water you use.

Slow cookers, water efficient showerheads, LED lights, loft insulation and smart thermostats can also help you lower your energy usage, but they might require some investment first.

Which appliances use the most energy?

Your boiler and shower will likely use the most energy, followed by large appliances like the washing machine and tumble dryer.

What can I do if I'm struggling to pay my energy bills?

If you’re struggling to pay for your energy, get in touch with your supplier to find out how they can help.

The government has an Energy Bills Support Scheme and a few other grants that could help you. Debt charity Turn2us has an online benefits entitlement calculator to help you figure out what support you can get with your energy bills.

If you need advice, you can chat to MoneyHelper (formerly the Money Advice Service), National Debtline or StepChange Debt Charity.
