Our Heat Pump Saver tariff is designed for customers who have an electric heat pump supplying their heating and hot water. It provides cheaper rates for using your heat pump during off-peak hours (between 11am and 4pm*). If you use less than 30% of your electricity during off-peak hours, another one of our tariffs may be more suitable for you.  You can compare these in your online account.

Our Heat Pump Saver tariff offers a lower rate of 14p per kWh between 11am and 4pm* every day and an average rate of 27.442p per kWh^† for the remaining hours. The lower rate allows you to save money on each kWh consumed during this period. The price of the energy we supply you is fixed, protecting you from any increase in wholesale energy costs. The tariff also includes variable costs which are linked to external industry costs that can go up or down each quarter during the term of your tariff. Find out more about the variable costs here

You need to be a ScottishPower energy customer to sign up to our Heat Pump Saver tariff. Not a customer yet? Join us on our Standard Variable tariff and move to the Heat Pump Saver tariff at no extra cost through your online account. Our tariff is designed for ScottishPower customers who have a heat pump – of any make or model – but the energy you use during off-peak hours includes all household usage. You must have a communicating smart meter that sends half-hourly readings and pay by monthly Direct Debit.

Yes, the tariff relies on data provided by smart meters throughout the day to ensure your bill is accurate. If you don't already have one, you can book a smart meter installation here.

At ScottishPower, we offer a range of leading heat pumps that provide low carbon heat and hot water for your home. Find out more, including how to get an initial, no obligation guide price here.

If you're moving home, you won’t be able to directly transfer this tariff to your new home. However, let us know when you are moving, and we’ll find similar tariffs we have available at the time.

The Heat Pump Saver tariff is both an electricity tariff and a dual fuel (electricity and gas) tariff, but there is no gas-only version. It’s only the electricity that will be subject to the off-peak hours, whereas your gas rates will be consistent throughout the day. This means that if you have a gas supply (e.g. for cooking) you will still receive one bill for both fuels rather than a separate bill for each fuel.

It’s likely that your gas usage will decrease on this tariff however, it depends on how you choose to use your energy. Any changes to both your gas and electricity use will be reflected in your quarterly Direct Debit reviews which will take account of your past 12 months’ energy use.

The more electricity use you can shift into the off-peak period, the better. There are no limitations on which appliances are and are not applicable, so shifting demand, especially programming your heat pump’s hot water schedule and boosting heating into the 11am – 4pm* period will help to reduce your home’s running costs. The more you’re able to move, the more you’ll save. If you have an air source heat pump, heating your hot water in the middle of the day (when the average ambient air temperature is warmer) will be more efficient than doing it at colder times of the day.

You can switch between any ScottishPower tariff at any time without paying exit fees, including our Heat Pump Saver tariff and EV Saver tariff.

The price you pay for your electricity will depend on your meter type and when you use it. For most customers, your price band will be as follows:

Peak:          16:00 – 10:59

Off-peak:   11:00 – 15:59

For customers with a SMETS1 meter made by L&G, Itron or Aclara, your off-peak rate is set by Greenwich Mean Time (GMT), meaning in the summer months whilst the UK is on British Summer Time (BST), between the last Sunday in March and the last Sunday in October, your off-peak times are different as outlined below:

Winter (GMT) Peak:         16:00 – 10:59

Winter (GMT) Off-peak:  11:00 – 15:59

Summer (BST) Peak:        17:00 – 11:59

Summer (BST) Off-peak: 12:00 – 16:59
