An update to your electricity tariff

An update to your electricity tariff

From 1 March 2026, a 2.5% increase to electricity prices came into effect. This will be shown in the first electricity bill you receive after 1 March. 

We understand that any increase in household costs can feel challenging, and we want to assure you that we have kept this adjustment as low as possible. For a typical all-electric home using around 10,000 units of electricity a year, the change amounts to around £60 per year, or just over £1 per week*. 

We first announced this change in November 2025 and chose to delay the introduction until March 2026 so that it wouldn’t affect bills during the colder winter months. 

If you’re concerned about your energy costs or would simply like to chat through the support available, our Customer Care team is here to help. We can make sure you’re on the best tariff for your needs and heating system and offer practical advice on using energy more efficiently.

For home Help Bills & payments Reducing your bill

Saving energy starts here

There are lots of ways to reduce your electricity use. In this guide we provide tips on the following topics:

Install good insulation

If you use electric heating, installing quality insulation can help reduce your bills by as much as £200 a year. If suitable, we recommend installing:

  • Cavity wall insulation
  • Loft insulation (at least 270mm)
  • Window insulation for any drafts

If this sounds like too much of a job, just closing your curtains at dusk can help keep heat in.

Be smart with your lights

Energy saving bulbs and LEDs use around 75% less electricity than standard bulbs. Changing the bulbs in your home isn't expensive, but the easiest way to save on your lighting costs is to turn them off when you leave a room.

Buy efficient white appliances

Of all the common home appliances, fridges, freezers, washing machines and dishwashers use the most electricity. If you're buying a new appliance, always choose one with an A+, A++ or A+++ energy rating.

Use appliances with energy saving in mind

Almost every appliance in the home can be used in a way that helps reduce electricity use. Here are some of the best ways:

  • Only run washing machines and dishwashers when full
  • Wash clothes at 30°C
  • Turn off appliances rather than leaving them on standby
  • Don't leave fridge/freezer doors open
  • Don't place your fridge/freezer next to an oven or in direct sunlight
