  • Energy scammers might pretend to be energy suppliers, regulators or other companies to gain your trust and try to steal your money or personal information.
  • Signs of an energy scam include being contacted unexpectedly, a deal that sounds too good to be true, being pressured to transfer money quickly or in an unusual way.
  • You should contact Citizens Advice or Action Fraud if you've been scammed. If you've handed over financial information, speak to your bank immediately.

Energy Saving Trust will never cold call you.

  • Our team will only contact you if you’ve asked us to, usually in response to you asking for information. If you get a cold call from someone who says they work for Energy Saving Trust, it’s a scam.

Energy scams involve people pretending to be energy suppliers, regulators, or other associated companies to gain your trust and get your money or personal information.

They can use the availability of grants, promises of cheaper energy, or offers of making your home more energy efficient as tactics to trick you. But there are many more ways they might try to scam you.

Scammers can contact you in many ways: 

  • a knock at your door
  • phone call
  • letter
  • on social media, including through adverts or sponsored posts
  • email
  • via a pop up on a website
  • text message

They might look legitimate, but sometimes that’s not the case. That’s why we’ve put together this guide to help you spot scams and know what to do you when you do.

What are the signs of an energy scam?

The best way to spot an energy scam is to know what to look out for. Here are some things which may suggest a scammer is at work:  

  • You’ve been contacted unexpectedly.
  • A deal looks too good to be true.
  • You’re being pressured to transfer money quickly.
  • You’ve been asked to pay in an unusual way.
  • You’ve been asked to give away personal information such as passwords or PINs.

When it comes to the method of contact, think about:

  • Poor phone line quality
  • Unprofessional formatting in an email or letter
  • Your phone indicating an incoming call may be spam

These are all signs of a potential scam. The Take Five website has more tips on spotting and avoiding different kinds of scams.

What do I do if I’ve found an energy scam?

If you think you’ve spotted a scam but haven’t yet given over any personal information or money, you can:

  • Contact Citizens Advice for support.
  • Forward suspicious emails to [email protected].
  • Forward suspicious text messages to 7726 (this is a free service you can report scam texts or calls to).

Reporting suspicious activities allows these organisations to investigate potential scams further.

What do I do if I’ve already handed over personal information or money?

If you’ve handed over any financial or personal information, or made a payment, talk to your bank or card company immediately. They can restrict or freeze your account to stop the scammers from doing anything else.

If you use mobile or online banking, you may be able to freeze your payment cards yourself via your bank’s app or website.

You should also report the scam to Action Fraud and Citizens Advice. They have information about the next steps you should take to protect yourself from further risks. You can also contact Police Scotland 101 if you live in Scotland.

By reporting scams, you can help reduce the chances of someone else getting defrauded.

What are the most common energy scams?

Common energy scams include:

  • Solar panel scams: companies pretending to be MCS to try and sell solar panel maintenance packages.
  • Ofgem energy scams: companies pretending to be Ofgem promising funding or cheap energy to get your personal details.
  • Meter reading scams: these target pre-payment meters and smart meters. People also pretender to be meter readers to gain access to homes.
  • Energy saving home improvement scams: companies tricking you into unnecessary work by saying it’ll make your home safe.
  • Energy rebate scams: companies trying to steal your personal details by promising money off their bills.
  • Warm Home Discount scam: a text scam targeting people about the UK Government’s Warm Home Discount.

How do I find out what energy efficient home improvements I need?

You can find suggestions for home energy efficiency improvements on your home’s Energy Performance Certificate (EPC).

Your EPC highlights potential energy efficiency improvements for your home, how much they’ll cost, and how much you could save.

Your EPC can be accessed online. As a result, people can find it and use it to try and scam you by suggesting work they know has been recommended to you. They might also suggest improvements that aren’t listed on your EPC.

In England, Wales and Northern Ireland, only accredited domestic energy assessors can produce valid EPCs. In Scotland, only organisations approved by the Scottish Government can produce valid EPCs.

How do I find a reliable, trusted installer?

Make sure your chosen installer is fully qualified and, if possible, accredited with a relevant industry body and/or trade federation:

  • The Microgeneration Certification Scheme (MCS) can help you find certified installers for renewable low-carbon energy products.
  • TrustMark is a government-endorsed quality scheme for work carried out around the home.
  • GasSafe Register is the official list of gas engineers.
  • OFTEC runs a competent person scheme for technicians who install and maintain oil, solid or liquid fuel heating systems.
  • FENSA is a government-backed scheme that monitors building regulation compliance of replacement windows and doors.

The UK Government website has a list of current competent person schemes for different trades. It’s also a good idea to ask installers about the warranties or guarantees they provide for the quality of their work or products.

We recommend getting at least three quotes for any work to give you an understanding of choice and ensure good value for money.
