Npower

Big six energy suppliers have been accused of keeping 1.5 million vulnerable and low income customers who receive a Government electricity discount on expensive standard variable tariffs.

Customers who recently made a complaint to their energy supplier are less satisfied with how it was handled compared to two years ago, Ofgem has revealed, with Npower considered to be the worst supplier at handling complaints.

Customers who move to the cheapest energy tariffs are facing eye-watering price rises once those deals end, research has found. But you can stay one step ahead of these hikes by switching suppliers.

If you're switching between many of the big energy providers you'll now benefit from 10 'commitments' guaranteeing a smooth and hassle-free transition – but if suppliers fail to deliver, you may still need to get the Ombudsman involved.

Npower has become the fourth big six energy firm to announce a price drop this year – it's cutting the price of gas by 5.2% from 28 March. But even after the cuts its standard tariff will cost £100s more than the market's cheapest, so check now to see if you can switch and save.

Customer complaints about energy firms increased by a quarter last year, according to the Energy Ombudsman. But whether you've had cause to complain about your provider or not, you can save £100s by switching now.

Npower has been fined a record £26 million after 500,000 customers received late and inaccurate bills. It comes after MoneySavingExpert was inundated with complaints from worried customers facing massive 'back bills', and we launched a campaign to get it to wipe or reduce them.

Co-operative Energy has blamed ongoing problems with its new IT system as the reason why it was the most complained about energy provider in the third quarter of the year.

Approximately 1,000 former and existing Npower customers will have debts written off and be given free energy, after the big six energy provider has been found guilty of failing to implement Ombudsman rulings on complaints within the required 28 days.
