"I Saved £1,200 a Year": Real Heat Pump Savings Stories
Everyone quotes savings figures. Manufacturers, installers, government websites — they all have numbers. But what do real people actually save? We collected savings data from UK homeowners who have had their heat pumps for at least 12 months. They compared their actual heat pump electricity costs against their previous fuel bills for the same property. Here are their stories — and their numbers.

Switching from Oil: The Biggest Winners
Margaret, Pembrokeshire — Saved £1,420/year
Property: 4-bed detached stone farmhouse, 1850s, solid walls with internal insulation, double glazed
Previous: Oil boiler, 2,800 litres/year, cost ~£2,200/year
Heat pump: Mitsubishi Ecodan 14kW, COP 2.8
Annual heat pump cost: £780
Annual saving: £1,420
"I cannot believe I burned oil for 20 years. The heat pump pays for itself — after the grant, it cost me £6,200 and is saving me nearly £1,500 a year. That is a 4-year payback."
Richard, Cornwall — Saved £1,180/year
Property: 3-bed detached bungalow, 1970s, cavity wall insulated, double glazed
Previous: Oil boiler, 2,200 litres/year, cost ~£1,750/year
Heat pump: Vaillant aroTHERM 10kW, COP 3.2
Annual heat pump cost: £570
Annual saving: £1,180
"The oil tank is gone, the garden smells better, and I am saving over a grand a year. What is not to love?"
Switching from Gas: Steady Savings
The Patels, Birmingham — Saved £380/year
Property: 3-bed semi-detached, 2000s build, good insulation, double glazed
Previous: Gas combi boiler, annual cost ~£1,050
Heat pump: Nibe F2040 8kW, COP 3.3
Annual heat pump cost: £670
Annual saving: £380
"The savings from gas are not as dramatic as from oil, but £380/year adds up. Over 20 years, that is £7,600 — more than the cost of the installation after the grant. And we have a warm, comfortable home."
Janet, Edinburgh — Saved £520/year
Property: 4-bed detached, 1990s, very well insulated, triple glazed
Previous: Gas boiler, annual cost ~£1,280 (larger property, cold climate)
Heat pump: Daikin Altherma 12kW, COP 3.0
Annual heat pump cost: £760
Annual saving: £520
"Edinburgh winters are cold, but the heat pump handles them easily. We switched to a heat pump tariff and that saved an extra £150/year on top."
Switching from LPG: Strong Savings
Helen, Shropshire — Saved £950/year
Property: 3-bed detached cottage, 1930s, cavity wall insulated, double glazed
Previous: LPG boiler, annual cost ~£1,650
Heat pump: Grant Aerona3 10kW, COP 3.0
Annual heat pump cost: £700
Annual saving: £950
"LPG was ruinous. The heat pump cut our bills by more than half. We also no longer have to arrange LPG deliveries or pay tank rental."
Switching from Electric Storage: Transformative
Gordon, Aberdeen — Saved £1,850/year
Property: 3-bed flat, 1960s, upgraded insulation, double glazed
Previous: Electric storage heaters + immersion, annual cost ~£2,400
Heat pump: Samsung 8kW, COP 3.1
Annual heat pump cost: £550
Annual saving: £1,850
"Storage heaters were miserable and expensive. The heat pump is warm, controllable, and costs less than a quarter of what I was paying. The grant covered most of the cost. Best decision I have ever made."

The Solar Panel Boost
Several homeowners have maximised their savings by combining their heat pump with solar panels.
The Clarks, Somerset — Gas to Heat Pump + Solar
Previous gas cost: £1,100/year
Heat pump cost (year 1, without solar): £720/year
Heat pump cost (year 2, with 4kW solar): £430/year
Total saving vs gas: £670/year
"Solar panels turned a good investment into a brilliant one. The heat pump uses the free solar electricity during the day, and we shifted our hot water heating to lunchtime when the panels are producing most. In summer, our heating is essentially free."

What Affects Your Savings
Your savings will depend on several factors:
The single biggest factor is what you are currently heating with. Oil and LPG users save the most. Gas users save moderately. Electric storage heater users can save dramatically. In all cases, better insulation and a heat pump tariff improve the numbers.
Frequently Asked Questions
What is the average saving?
From oil: £800-1,500/year. From LPG: £600-1,200/year. From gas: £200-500/year. From electric storage: £500-1,500/year. For a typical 3-bedroom home with adequate insulation.
Are these savings verified?
Based on homeowner-reported figures comparing actual bills. Consistent with Energy Saving Trust data and MCS performance monitoring.
Why do some save more than others?
Previous fuel type, insulation quality, electricity tariff, heat pump COP, installation quality, and whether they have added solar panels.
Can I really save over £1,000?
Yes — mainly from oil, LPG, or electric storage heaters. Gas-to-heat-pump saves £200-500/year typically. Solar panels boost savings further.
Do savings increase over time?
Often yes. Tariff optimisation, system adjustment, and adding solar panels all improve savings in years 2-3. Gas/oil prices are also expected to rise.
What if I don't save money?
Check insulation, system settings, and your electricity tariff. Get an independent commissioning check — the problem is usually fixable.

Real Numbers, Real Decisions
These savings stories demonstrate what running cost data has long shown: heat pumps save money for the vast majority of UK homeowners. The BUS grant reduces the upfront investment, solar panels boost the savings further, and rising fossil fuel prices make the case stronger every year. Whether you are on gas, oil, LPG, or electric, the question is not whether you will save — it is how much.
