Go directly to the supplier

Firstly, go straight to the supplier directly as opposed to the ombudsman.

Our supplier guide pages can help you find the relevant contact details for your provider.

Before picking up the phone, make sure you’re fully equipped with the relevant information to make the complaint process that much smoother. 

Have your customer reference number to hand - this should be on the top of your latest bill - and it might also be worth making a note of your meter reading if you have one.

During the call, take notes of any important details and be sure to ask questions if you don't understand something. Make a record of the time and date of the call and also the name of the person you spoke to.

Write a letter

If you cannot resolve your complaint via a phone call, you should put pen to paper and write the complaint as a letter, too. State within the letter that it is a complaint, and make sure you save a copy for yourself for future reference.

Depending on the nature of your complaint, you could also include copies of bills, tariffs or previous correspondence. And if you have a case reference number, include that too.

Sending your letter of complaint by recorded delivery will allow you to track the letter and prove it was sent, using the receipt.

What if the complaint is still unresolved?

Your complaint should be escalated through the company in accordance to its complaints handling procedure. Details should be on its website.

If the supplier has not resolved your complaint after eight weeks, or if, after your call, letters and follow-up conversations, you are still not satisfied with how your complaint was handled, you should take it to the energy ombudsman.

The ombudsman service is free to use and independent of gas and electricity suppliers, and of the regulator Ofgem.

You can find the ombudsman service online at http://www.os-energy.org/ or you can contact the service by phone on 0330 440 1264.

Can anyone else help?

Aside from the ombudsman, you could also contact Citizens Advice.

Citizens Advice has taken over the role previously carried out by the government-funded Consumer Direct call centre.

It offers free, impartial advice and can also be reached on 0345 404 0506.

Switch and save

If your complaint is about the cost of your energy bills, it’s worth considering switching your supplier, as this is likely to reduce the amount you spend on your energy bills.

Switching energy supplier isn’t as difficult as you might think, and the process is fully taken care of by your old and new supplier.
