The best of both worlds; retain your gas heating, while taking advantage of heat pump technology
If you're looking to reduce your heating bills without completely replacing your existing boiler, a hybrid heating system could be the perfect solution.
By combining the efficiency of an air source heat pump with the backup of a gas or oil boiler, hybrid systems offer the best of both worlds; comfort, savings, and peace of mind.
In this guide, we’ll explain how hybrid heating works, who it’s best suited for, and why it’s growing in popularity across the UK.
What is a hybrid heating system?
A hybrid system connects an air source heat pump to a traditional gas or oil boiler. It uses smart controls to switch between the two, automatically choosing the most efficient or cost-effective heat source based on outside temperature, fuel prices, and your home’s energy needs.
- When it’s mild outside, the heat pump does most of the work.
- When it gets very cold or when hot water demand spikes, the boiler steps in.
You get maximum comfort and efficiency, with no need to manually switch anything.
How do hybrid heating systems work?
- A heat pump is installed to work alongside your existing boiler.
- The system constantly monitors performance, temperatures, and energy prices.
- A smart controller automatically chooses which source to use — or uses both together when needed.
The system provides both space heating and hot water.
What are the benefits?
Hybrid systems are ideal for homeowners who want to improve their energy efficiency but aren’t ready (or able) to switch fully to a heat pump.
- Lower heating bills: Save by using the heat pump for most of the year
- More efficient than a boiler alone: Especially in spring/autumn when full boiler output isn’t needed
- Reduced carbon footprint: You’ll use your boiler far less
- Flexible upgrade path: Ideal for homes that may not be fully ready for a standalone heat pump
- Year-round comfort: Always delivers the heating and hot water you need, no matter the weather
How do hybrid heating systems compare?
Running costs depend on your electricity tariff, home insulation, and heating controls. Well-insulated homes with off-peak or smart tariffs tend to see the biggest savings.
| Feature | Hybrid System | Gas/Oil Boiler | Air Source Heat Pump |
|---|---|---|---|
| Efficiency | High (200-300%) | Moderate (85-95%) | Very High (300-400%) |
| Upfront Costs | Medium | Low to Medium | High |
| Running Costs | Low | High | Lowest |
| Carbon Emissions | Moderate | High | Low |
| Hot Water Performance | High | High | Varies - Requires Cylinder |
Is my how suitable for a hybrid heating system?
Hybrid systems are most suitable for:
Larger or older homes that are harder to insulate
- Households with high hot water demand
- Properties with limited space for heat pump-only setups
- Homes already using a gas or oil boiler in good condition
We’ll carry out a full home assessment to recommend the best setup for your needs and budget.
Will I still need to use my boiler?
Yes — but far less often. The system is designed so that the heat pump handles most of the work, especially during milder weather. Your boiler only kicks in when it’s really needed, helping to extend its life and reduce your fuel use.
How much do they cost?
Costs vary depending on your current system and the type of heat pump installed, but typical hybrid system installations range from £6,000 to £12,000.
You may be eligible for government support (such as ECO4 or Boiler Upgrade Scheme), which could reduce the cost significantly. We’ll help you explore your options.
