Introduction: Heat Pump Old Homes – Can They Really Work?
Heat pump old homes — it’s a common concern among UK homeowners living in properties built before modern insulation standards.
At Air Source Company, we’ve helped retrofit heat pumps in hundreds of properties ranging from Victorian terraces to 1930s semis. The truth is: most older homes can support a heat pump with some insulation work and the right design. And in many cases, grants cover the cost of those improvements.
So yes — you can enjoy greener, cheaper heating in your older home.
Why Are Heat Pumps Ideal for Older UK Homes?
1. Energy Efficiency Over Time
Unlike gas or oil boilers that burn fuel, heat pumps transfer warmth from the air — even in winter — using electricity. That makes them highly efficient, especially when combined with good insulation.
2. Lower Running Costs
If your home currently uses oil, LPG, or electric heaters, you could save hundreds per year by switching to a heat pump. Heat pumps offer consistent indoor temperatures and reduced monthly bills over time.
3. Government Funding Available
Schemes like the Boiler Upgrade Scheme (BUS) and ECO4 provide grants of up to £7,500 — even more if you're on a low income. These are designed specifically to help retrofit older homes.
4. Boost Property Value
Energy-efficient homes are in high demand. A heat pump not only improves your EPC (Energy Performance Certificate) but also makes your home more attractive to future buyers.
Is My Old UK Home Suitable for a Heat Pump?
Key Considerations:
Insulation: The better your insulation, the better your heat pump will perform. Many older homes need upgrades like loft insulation, floor insulation, or internal wall insulation. Fortunately, these can often be grant-funded.
EPC Rating: Homes with an EPC of D or lower may need some improvement. ECO4 and BUS grants typically require basic insulation, which we can assess and help you install.
Heating System: Radiators are fine. In fact, many UK homes keep their existing radiators. Larger ones might be installed in key rooms to improve heat output.
Location: Heat pumps work well across all regions — including colder areas of the UK like Scotland or Yorkshire.

Common Questions Homeowners Ask About Heat Pumps in Older Homes
Q: Can a heat pump work in a home with solid walls?
Yes. Many older homes with solid walls can use internal or external insulation to become heat pump–ready. ECO4 funding may help cover insulation costs.
Q: Will I need to replace all my radiators?
Not always. We assess your current system and recommend changes only where necessary. Often, just a few radiators are upgraded.
Q: Is it expensive to retrofit an old house?
With grants like ECO4 or BUS, you may pay very little — or nothing at all. Upgrades are cost-effective and long-term savings make it worthwhile.
Q: Will a heat pump keep my house warm in winter?
Absolutely. Modern heat pumps work down to -15°C. With proper design, your home will stay cosy year-round.
Q: How long does it take to install a heat pump?
Usually 2–4 days, including insulation and system upgrades. Our process is clean and hassle-free.
Q: Can I keep my existing boiler?
Yes — in some cases, homeowners choose a hybrid system. We’ll help you decide based on your home and preferences.
How to Prepare Your Old Home for a Heat Pump
1. Check Your EPC Rating
You can request your home’s EPC from the government database. If it’s rated E, F, or G — you may be eligible for funding and insulation upgrades.
2. Improve Insulation
Insulation is key to performance. Consider:
Loft insulation (most cost-effective)
Internal wall insulation (for solid walls)
Underfloor insulation (where accessible)
Even small improvements make a big difference.
3. Review Your Heating Distribution
If your radiators are older or undersized, we’ll assess and replace only where needed. Underfloor heating is optional, not essential.
4. Evaluate Existing System
Still on oil, LPG, or an old gas boiler? These are ideal candidates for replacement. You’ll see faster savings with a heat pump.
