Heat pumps work differently from boilers. A boiler typically heats a home in bursts, switching on hard for a few hours in the morning and evening. A heat pump is usually most efficient running 'low and slow': keeping water at a modest temperature for longer and holding rooms at a steady temperature rather than reheating them from cold. Many people find this takes a week or two to get used to.
Across County Durham and County Durham, heating curves are fine-tuned after the first cold spell to suit how each house responds. Hot water schedules in County Durham can be timed to suit shift work, school runs or working from home. We set up weather compensation for each County Durham home from its own heat loss design, not a factory default.
Who it suits
- Homes with an extension, loft room or areas heated at different times
- Every new heat pump installation, set up at commissioning
- Existing heat pumps that feel expensive to run or slow to respond
- Households considering a heat pump or time-of-use electricity tariff
Grants and rules for heat pumps in England
Homes in County Durham can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Heat pump controls and tariffs questions
Can I control my heat pump from my phone?
Many heat pumps offer an app or work with smart thermostats, letting you change temperatures, set schedules and see energy use from your phone. Features vary by make and model, and app control usually needs a reliable internet connection at home. The heating keeps running on its own settings if the connection drops.
How should I set the hot water on a heat pump?
Most households heat hot water once or twice a day at set times rather than on demand. Timing the main heat for a cheaper tariff period, or for the middle of the day when solar panels generate, helps keep costs down. A weekly legionella cycle raises the water temperature higher, and we schedule it at a sensible time.
Is a heat pump tariff a good idea?
A heat pump or time-of-use tariff can lower running costs if your household can shift hot water heating and some space heating into the cheaper periods. Whether it suits you depends on the rates, the standing charge, your routine and whether you have a battery. Compare the total expected cost on your own usage, not only the headline rate.
Should I turn my heat pump off at night?
Usually not. Switching off lets the house cool, and the heat pump then has to run at a higher flow temperature to recover, which lowers efficiency. A small set-back of 1–2°C overnight is generally more economical. Homes with very good insulation or a time-of-use tariff may suit different patterns, which we can set up.
