About two million E.on customers will stop earning reward points at the end of March after the energy supplier decided to pull the plug on its popular scheme. If you opted in to E.on Rewards, you'll have until 30 June 2017 to exchange your accumulated points for Tesco Clubcard points or Bonusbond vouchers.

New and existing customers on the supplier's standard tariff – E.on EnergyPlan – will continue earning monthly points until 31 March 2017. If you're on a fix that offers the rewards scheme (not all E.on fixes do), you'll be given all the points you've earned during your fixed period upfront within 28 days from the end of March.

The scheme itself is set to end on 30 June 2017, which means customers on E.on's standard tariff and those on an eligible fixed tariff will need to redeem all their points by then.

How does the E.on Rewards scheme work?

With E.on Rewards, you could earn up to 1,500 reward points each year by opting in to the scheme on one of its electricity-only or dual-fuel tariffs. You didn't need to do anything to earn the points, just be on an eligible tariff and you'd start accumulating them each day.

Once earned, you can exchange these points for Tesco Clubcard points or Bonusbond gift vouchers.

Each E.on Reward point is worth one Tesco Clubcard point – or potentially four times more if you use Clubcard Boost. (For other ways to boost your Clubcard points once the E.on scheme ends, check out our Reclaim & Boost Tesco Vouchers guide.)

If you opt for Bonusbond gift vouchers – which are accepted at more than 18,000 shops, restaurants, bars and hotels – 500 reward points would net you £5.

How do I check if I've points to spend?

To check how many points you have or to redeem them, you can log in to your online account and navigate to the rewards section or contact E.on on 0345 059 9905.

It's worth noting that since the beginning of December 2016, no new fixed tariffs have offered E.on Rewards – so you won't be on the scheme if you've signed up to a fixed tariff with E.on in the past six weeks.

If you've opted in to the scheme via an eligible tariff, you'll be contacted by E.on with info on what happens next.

Will E.on replace the scheme?

E.on is yet to confirm whether or not the scheme will be replaced, but a spokesperson told us: "We regularly review our products and services and, although the E.on Rewards scheme is coming to an end, we remain committed to offering competitive prices as well as solutions and benefits that'll help customers save energy and pay less."

How else can I save?

Though E.on Rewards offered a simple, effortless way of getting a bit extra from your tariff, it's possible to save £100+/year by switching your supplier. Do a comparison via our Cheap Energy Club to see how much you could save.
