Ofgem launched an investigation into Maxen Power Supply Limited about its fair treatment of businesses and matters relating to energy theft. I do not recommend this company based on my own negative experience.
Maxem power broken into my property I have received call from my tenants, 2 man wan came into my property . He asked who I said I didn’t know as no one at home and I was left home 2 hours and door was lock. I was back home immediately and they left the property but I have seen guy driving small private car with uniform with power supply came out from my property. When I checked my property, this 2 guys was open bedroom door, all kitchen door and toilet and broke my toilet floor. They has told my tenant to pay the outstanding bills for £4000 but I have only owe £2000 and intend to pay this Fri. They have also sent someone here to disconnect the electricity supply without warrant. But they could not came in. I have done the payment for them on November for £1950 that left over £950 to pay on December. When the December bills came, this payment I have done was not allocated onto my account. It was only allocated £1095, then I sent email to ask about this bills and no reply. After 10 days they sent their staff broken into our property and damaged our property. I then call them, the manager told me they have the right to broken into my property because first attempt was fail. Second time they can broken into our property. On the first attempt, I have make payment to them for £1950. I have report this to police and send the CCTV footage to police. They said they have warrant but could not show us. We have 6 months old baby leave here. If they disconnect without warrant I will take them to court and I have pay my bills. When I call the manager, he requests me to pay £5100 that my bills only £2000 they charge £1000 to broken into my property plus fine added to my bills. All their reviews is fade. I have never seen any energy company can broken into your house and added charge to my bills. It is so difficult time, if they kept added extra onto bills left us no choice for them to cut the power and we will call police and council as we have baby here suffer with. We have pay the bills, we didn’t not pay the pay. Every 6 week they sent their staff here and added the fine n extra. How we effort to pay. This is scam company If I can post photo to proof I would . All door and bedroom left open, like gangs went into your house and walk out from your house plus charges £1000 to you

This is a scam company. Because my English is not very good, I mistakenly signed a 3-year contract with them for my business. In the first month, for only 11 days, they charged me nearly £1,300 in June — during summer — even though I hardly used any gas at all. In the following months, they continued to add unreasonable extra charges. I realised they are scamming customers, but I cannot leave because my contract has not ended yet. I’m sharing this to warn others — please check very carefully before signing anything, and don’t make the same mistake I did.
I would not even give Maxen Power one star. They are basically harassing our company telling lies that OFGEM have told them to contact us. I have told them not to call us at least 5 times in the last 2 weeks, but they keep calling under different guises - the latest was they were calling from our current supplier. This is pure harassment and needs to stop.
⭐ 1 Star – Billing for electricity that physically did not exist I took over a commercial premises on 17 November 2025. When I moved in, Maxen Power had physically removed the electricity meter due to the previous tenant. There was no power, no meter and no way to use electricity. Despite this, Maxen issued me: • A bill from 17 Nov – 1 Dec (which I paid under protest) • A second, larger bill for December — even though the meter was still not installed The meter was only installed on 5 January 2026, and on that same day I switched to EDF. Maxen then objected to my supplier transfer unless I paid the December bill for a period when there was no supply and no meter. This has caused serious disruption to my business and is now being escalated to Ofgem and the Energy Ombudsman. I am also extremely uncomfortable with the way Maxen encourages customers to leave Trustpilot reviews when they feel they’ve been “helped” — something I personally experienced during this dispute. It’s a bully boy tactic to boost their trustpilot reviews. That’s how I describe there actions as soon as you have a disagreement. No company should be billing for energy that could not physically be used, or blocking customers from switching supplier to force payment of a disputed invoice. Proceed with caution. — David Woodburn
it is shocking that 89 reviews in a day and all of them 5 star 5 days before. similar to 56 reviews 5 star in a day in a december when we call Maxen power they always busy and never solve the problems straight away, always some one will call back which never happened. The team even does not have time to get back to customers via emails. ridiculous customer service but still get 5 star.. wow!! impressive!!!
The worst utility company. After moving into a property that had no meters Maxen Power had these installed on the 16th December. The electric was turned off at the DB instantly as the building is unoccupied and the gas engineer has not attended yet to connect the gas so it is impossible for any gas to have been used. I have just received a bill for December for £609.49 including the whole month of Decembers standing charge (31 days) when the meters were only installed for 16 days at £2 per day plus ridiculous gas and electric usage even though proof was sent of both meters showing they had not been used. After calling this morning they confirmed the bills were wrong but only because I questioned them. They then sent a new bill out for £175 still with 31days standing charge for each meter. This is after having to pay £4k deposit as the previous tenant left in arrears and £450 for each meter install. Stay clear of this company and ignore the fake reviews.
Do not trust this company and all these reviews are fake . this company must be banned.
0 star . This company is like walking to a man made trap where they will make you enter without your consent no written contract no nothing their agent will ask for bank details lure you to cheap rates but infact they will charge you very higher rates than in the market. Please be aware of these frauds. Don’t fall for them. And one more thing same person will talk to you over the phone with different names . Soo scamming .
