Getting things right for our customers

Following our letter of apology to all customers in December 2013, we've been working really hard and made real progress, both on problems we've had and the overall service we're now providing.

Putting things right

We’re working hard to make sure we get things right for our customers but sometimes, things can go wrong. If this happens, we want to know as we value your feedback. This way we can make sure we put things right.

You can see what actions we're taking by looking at our 'top 5 causes of customer complaints'.

Billing open/close

We want to make sure you know you’re paying the right amount for the actual energy you’re using, so:

  • We’ve changed how our bills look so they’re much easier to understand.
  • We’ve posted a video to explain the changes we’ve made to make things simpler for you.
  • We’ve also improved our customer service web pages to make sure information is available 24 hours a day – just when you need it.
  • Our Tariff Comparison Rate checker lets you compare your gas and electricity prices quickly and simply so you can check you’re on the right tariff for you.
  • You can quickly check your bills online – it’s really simple to sign up for this.
  • Regular meter readings mean accurate bills – you can send us a meter reading online – even if you haven’t registered as an online customer.

Payments open/close

The amount you pay can depend on the time of year, the tariff you are on and the amount of energy you’re using. We want to make sure you’re paying the right amount so:

  • We’ve changed how our bills look so they’re much easier to understand.
  • We’ve posted helpful videos on our website to explain how payments are calculated.
  • Our online direct debit web page tells you all you need to know about paying by direct debit.
  • We’ve recently launched a handy app, for smartphones, which will also provide access to these details.

Metering open/close

We read your meter regularly so we can make sure our information is up to date – such as checking it’s correctly recording your energy use and working safely.

  • We’re working closely with our metering agents to make sure they keep their promises when they say they will visit your home.
  • We’ll also remind you when your meter needs a safety check.
  • Regular meter readings mean accurate bills – you can send us a meter reading online – even if you haven’t registered as an online customer.
  • We’re moving forward with our plans to fit Smart meters and we’ll be doing this over the next 6 years. Smart meters come with a portable Smart energy display that makes it easier for you to understand how much gas and electricity you’re using and gives you a good idea of how it affects your bill - helping you make smarter choices about the energy you use. Smart meters also send us your energy data to us remotely so you won’t need to stay in for someone to read your meter or give us a reading yourself. You don’t need to do anything - we’ll let you know when we’re installing Smart meters in your area.

Switching / transfers open/close

You’ve told us how frustrating it is if you have to wait longer than expected to switch your energy.

  • Our online guide explains the switching process. And, if you’re moving home, this guide will make it simple.

Debt open/close

No one likes the idea of money worries, so:

  • We work closely with organisations like National Debtline and Citizens Advice to help customers who are finding it hard to pay their bills.
  • Our Spreading Warmth Programme help to those most in need such as the elderly, low income families, disabled and chronically sick. We offer help to manage your bills, keep warm and reduce energy costs.
  • We have a dedicated Energy Efficiency Helpline to help you make your home more energy efficient, there by potentially reducing your energy use - and your carbon footprint.
  • Our npower Energy Fund helps npower customers who are struggling to pay for energy debt.
  • So, if you’re finding things difficult, please get in touch. We’d like to help.

Late invoicing

We previously saw some problems with our new billing system, which meant we couldn’t bill some of our customers on time. We’re working really hard to make sure we can bill all of our customers on time although there will always be instances where this may not be possible. For example if we have conflicting meter readings, which need investigating.

Here’s our progress to date.
