After 4 years arguing with First Utility about not reading my gas meter, Resolver had it sorted within 2 weeks and the refund soon followed.

As soon as Resolver got involved the problem was sorted out within weeks and I received some compensation from Scottish Power.

Took on Scottish power after 2 years of continued refusal to listen to one word I was saying. Amazing support and fantastic outcome, thank you x

Absolutely brilliant website - I managed to get back over £300 that an energy provider owed me from when they went bust well over a year ago. I had had no joy until I used Resolver and now all the money is safely back in my account. It was so easy and stress free. Thank you!

Have used Resolver twice. First with PPI, got a nice cheque. Secondly, an energy provider were avoiding all my attempts to obtain a refund for my elderly Mother who was paying twice the monthly amount and amassing a huge amount of credit. No emails, letters or calls made any difference until I got Resolver involved. In less that 7 days, they issued a refund and halved her monthly direct debit.
Chris N via facebook
Used Resolver to get over £32000 of mis-sold PPI, just filled in the online form, only a couple asked for further information. All the companies responded within the times allowed, and easy to keep an eye on dates just by logging in. Also used it with an energy provider over a metre change/billing problem and received compensation.

e.on complaints

Under the Energy Complaints Handling Regulation of October 2008, e.on is required to report on the number of complaints it receives per quarter. Ofgem is the office of gas and electricity market – it regulates this market and asks e.on to report the number of complaints. Higher-level complaints data are available on its website, and it also provide an annual report highlight of the total number of complaints received. These reports do not include details of whether the issue was resolved to the customer satisfaction. When making a complaint to e.on about issues such as overbilling that you explain your issue, what you want to achieve and what e.on needs to do to resolve your complaint.

e.on’s background

Originally British-owned power company Powergen, e.on UK has been the British branch of German energy supply firm e.on since 2002. It is one of the ‘big six’ suppliers of energy (gas and electricity) to British consumers along with British Gas, EDF Energy, npower, SSE and Scottish Power. Although originally a generator, distributor and supplier of gas and electricity, it now concentrates solely on the supply side of the market.

What if e.on cannot resolve your issue?

If e.on cannot resolve your issue then you have the right to go to the ombudsman, who will independently assess your issue. The ombudsman responsible for the energy sector is called Ombudsman Services and they are based in Warrington. Ombudsman Services links to Resolver from its website and recommends that you use Resolver to help you submit your complaint to e.on. The ombudsman will assess your e.on complaint and determine if it is valid. Its recommendation is binding on the company, but not binding on you.

If the complaint is about an insurance policy from e.on such as Boiler Support, Drains Support etc, then these are not covered by the Energy Ombudsman but the Financial Ombudsman Service, as the policy is an insurance rather than an energy product. Complaints relating to these products follow the same procedure but will go the Financial Ombudsman Service to be dealt with.

How can I send a complaint to the ombudsman?

Both Ombudsman Services and the Financial Ombudsman Service can accept cases from you eight weeks after you have raised the complaint with e.on. They cannot take the case any earlier unless you have received a deadlock letter from the company. A deadlock letter essentially formal confirmation that the company will not resolve your complaint without further intervention.

Is the ombudsman independent?

Ombudsman Services, the Energy Ombudsman is independent from the energy industry and whilst it is funded by case fees, it is required by Ofgem to ensure its judgements are fair and reasonable. The outcomes of cases are checked by a number of organisations such as consumer rights organisations, as it is essential that the cases are judged in a fair and reasonable manner. Ombudsman Services is a member of The Ombudsman Association.
