ScottishPower Heat Pump Review 2026
ScottishPower installs MCS-certified air source heat pumps from Mitsubishi, Vaillant and Daikin, and pairs them with the Heat Pump Saver tariff built for heat pump homes. The £7,500 grant is applied to bring the net cost down, and every install comes with a two-year workmanship warranty and two years of annual servicing. The Saver tariff is the standout, but it is worth comparing against independent MCS installers before you commit.
Quick Answer
ScottishPower installs MCS-certified air source heat pumps from Mitsubishi, Vaillant and Daikin, with the £7,500 grant applied to lower the net cost. The Heat Pump Saver tariff gives a cheaper 14p per kWh rate from 11am to 4pm every day, and is open to any heat pump home, not just ScottishPower installs. Independent MCS installers are worth comparing on price and lead time.

How much does a ScottishPower heat pump cost?
ScottishPower quotes each home individually after a survey, with the grant deducted before you pay. Air source systems generally run £8,000 to £14,000 before the grant, so the net cost for a standard, reasonably insulated home typically lands at a few thousand pounds. Larger or harder-to-heat homes pay more. As with any installer, the final price depends on your heat loss survey, the unit size and any radiator upgrades. Compare it against our independent heat pump cost guide.
| Item | Typical Range |
|---|---|
| Air source system before grant | £8,000–£14,000 |
| Less £7,500 grant | −£7,500 |
| Net cost to you | £500–£6,500 |
