Heating your home efficiently has never been more critical, especially with rising energy costs in the UK. Choosing the right heating system can save you hundreds of pounds every year. This guide will walk you through the different heating systems available, comparing gas, electricity, oil, and renewable energy options, and provide tips to reduce your heating bills.
Key Takeaways:
- Heat pumps are the most efficient heating systems, with up to 400% efficiency.
- Gas remains the cheapest fuel source for heating, despite being less efficient than electricity.
- Improving home insulation and using smart heating controls can drastically reduce heating costs.
- Renewable energy options such as heat pumps and solar panels offer long-term savings but come with high upfront costs.
Gas vs. Electricity: Which is Cheaper?
When it comes to comparing gas and electricity costs, gas still holds the upper hand. As of 2024, natural gas costs around 10.3p per kWh, while electricity averages 34p per kWh. This price difference makes gas boilers cheaper to operate than electric heating systems. However, electricity-powered systems like heat pumps offer higher efficiency levels.
While heat pumps are more efficient—often achieving efficiency rates between 250% and 350%—the high cost of electricity means that gas boilers are still cheaper to operate for most households in the UK. Heat pumps may only become more cost-effective if electricity prices drop significantly or if the home’s thermal efficiency is exceptionally high.
Oil and LPG: How Do They Compare?
For homes that aren’t connected to the gas grid, oil and LPG boilers are popular alternatives. On average, heating oil costs around 9p per kWh, slightly cheaper than natural gas. LPG, on the other hand, costs approximately 12p per kWh. Both options require on-site storage and regular refueling, which adds to their overall cost.
While oil and LPG boilers offer 90-93% efficiency, they involve additional logistics, such as maintaining and refilling storage tanks. This makes them less convenient than gas or electricity but still viable for rural households.
Cheapest Type of Heating in the UK
Based purely on running costs, natural gas boilers remain the cheapest option. Despite their lower efficiency compared to electric systems, the significantly lower cost of gas makes them unbeatable in terms of cost-effectiveness.
Despite their high efficiency, air-source heat pumps may not deliver the same cost savings due to the high cost of electricity. In some homes, particularly those with poor insulation or old windows, gas boilers remain the better option. For homeowners looking to reduce energy costs, the focus should be on improving home insulation and minimizing heat loss.
Renewable Energy: Solar Panels and Heat Pumps
Renewable energy options like solar panels and heat pumps offer long-term savings and are environmentally friendly. Solar panels, although only 10-25% efficient, have the benefit of zero running costs once installed. If paired with an electric boiler, solar panels can significantly reduce heating bills. However, the upfront costs are substantial.
Heat pumps, particularly ground source heat pumps, offer up to 400% efficiency. This means they can produce more energy than they consume. However, heat pumps come with high installation costs, often making them less accessible for households on a budget. Despite the higher efficiency, the financial payback may take years to realize unless you have access to government incentives like the Boiler Upgrade Scheme (BUS).

Factors Impacting Heating Costs
Several factors affect how much you’ll spend on heating:
- Property Size: Larger homes naturally require more energy to heat, driving up costs.
- Insulation: Poorly insulated homes lose heat quickly, making heating systems work harder and increasing energy bills.
- Fuel Type: Gas is cheaper than electricity, while oil and LPG sit somewhere in between.
- Heating System Efficiency: More efficient systems like heat pumps or modern condensing boilers can lower fuel consumption.
- Smart Controls: Installing smart thermostats and zoning systems can save up to 31% on heating bills by optimizing when and where heat is used.
How to Reduce Your Heating Bills
Lowering your heating bills doesn’t always require a new boiler or heating system. Here are some effective ways to cut down on costs:
Smart Heating Controls
Smart heating controls, like programmable thermostats and zoning systems, allow you to control your heating more effectively. You can set different temperatures for different rooms and schedule heating to only come on when necessary. Smart thermostats can reduce heating bills by 8-16%, with some models claiming even greater savings.
Improved Insulation
Upgrading your home’s insulation is one of the most cost-effective ways to reduce heating bills. Wall, loft, and floor insulation can prevent heat from escaping, keeping your home warmer for longer. Adding double or triple-glazed windows, thermal curtains, and better-insulated doors can further improve thermal efficiency.
Energy Tariffs
Another way to save money is by reviewing and switching your energy tariff. As of 2024, with the Energy Price Guarantee (EPG) in place, switching might not be immediately beneficial, but monitoring future tariffs could present better options when prices stabilize.
What Heating System Is Right for You?
Choosing the right heating system depends on your budget, property size, and environmental goals. Here’s a quick comparison:
- Gas Boilers: Cheapest to run and relatively low upfront costs, but less efficient than electric systems.
- Electric Boilers: High running costs but easy to install in homes without gas access.
- Heat Pumps: Highly efficient and eco-friendly but expensive to install.
- Solar Panels: Zero running costs but low efficiency and high upfront costs.
- Oil and LPG Boilers: Suitable for off-grid homes but involve logistics like refueling and maintaining storage tanks.

Future-Proofing Your Home Heating
With the increasing focus on sustainability, many homeowners are considering switching to renewable energy sources. If you’re looking to future-proof your heating, investing in solar panels or a heat pump may be a wise decision, despite the high initial costs.
For those on a tighter budget, upgrading to an A-rated condensing gas boiler and adding smart heating controls offer the best balance between upfront cost and long-term savings. You could also look into installing underfloor heating, which works well with both gas and electric systems to distribute heat more efficiently.
For environmentally conscious households, combining solar panels with an electric boiler or heat pump provides both cost savings and a reduced carbon footprint. While this approach requires a significant initial investment, it can yield long-term financial benefits and contribute to a more sustainable future.
Conclusion
In summary, gas boilers are the most cost-effective heating systems in the UK based on current energy prices. While electric systems like heat pumps offer higher efficiency, the high cost of electricity makes them less attractive for most households.
For homeowners looking to save money, focusing on improving insulation and adding smart controls can lower energy consumption without the need for expensive upgrades. If you’re ready to invest in renewable energy, options like solar panels and heat pumps offer long-term savings, but it’s essential to consider the upfront costs.
By carefully weighing your options and considering both running costs and installation expenses, you can choose the most efficient and affordable heating system for your home.
