Heating oil prices have ranged from 40p/L to £1.40/L in recent years. At higher prices (£1.20/L), annual costs reach £2,824 - making heat pump savings £1,091/year or £10,910 over 10 years.
Heat pumps provide price stability - your costs are predictable and protected from oil market shocks.
Even with tank removal and higher upfront costs, heat pumps save significantly over 10 years

Never wait for oil deliveries, worry about running out, or schedule tank refills. Heat pumps connect to the grid - always available.
Remove bulky oil tanks (1,000-2,500L) and gain valuable garden space. Many clients add patios, sheds, or landscaping in freed-up areas.
Oil prices fluctuate wildly (40p-£1.40/L). Electricity prices are more stable and predictable, making budgeting easier.
Eliminate oil spill risks, tank corrosion concerns, and environmental liability. Heat pumps are clean, safe, and eco-friendly.
Rural properties with heat pumps achieve better EPC ratings and appeal to buyers seeking modern, sustainable homes.
Mild maritime climate (rarely below -5°C) is ideal for heat pumps. Modern systems work efficiently to -25°C.
Yes, significantly. Heat pumps cost £800-£1,200/year vs oil boilers at £2,000-£3,000/year for a typical 4-bed Dorset home. That's £1,200-£1,800 annual savings. With volatile oil prices (fluctuating £0.50-£1.20/litre), heat pumps provide price stability and predictable running costs.
New oil boiler: £3,000-£5,000 installed. Heat pump: £8,000-£18,000, BUT with up to £9,000 BUS grant, net cost is £500-£10,500. The difference is £0-£7,500. With £1,200-£1,800/year savings, payback is 3-6 years. After that, pure savings.
Not immediately. You can leave the tank in place initially (some people keep oil as backup). However, we recommend professional tank removal (£500-£1,500) to free up space and eliminate environmental risks. Many Dorset homeowners gain valuable garden space by removing bulky oil tanks.
Often yes, but depends on insulation. High-temperature heat pumps (delivering 60-70°C) work with most existing radiators. Well-insulated homes may only need 1-2 larger radiators. We assess during free survey and provide honest advice on any upgrades needed.
Even at the lowest historical oil prices (60p/litre), heat pumps cost similar or less to run. At current/average prices (80-120p/litre), heat pumps save £1,000-£2,000/year. Plus, oil will become increasingly expensive as demand declines (2035 heating oil ban likely follows gas ban).
