Best Ways to Reduce Heating Bills: Quick Overview
Heating accounts for a significant portion of most household energy costs, particularly during the colder months. If your heating bills have crept up year on year, you’re not alone, many homeowners face the same frustration. The good news is that there are proven, practical methods to reduce heating bills without sacrificing comfort or warmth.
This guide from Apex Gas & Heating Ltd covers seven effective strategies you can implement today. Some require minimal investment and effort; others deliver long-term savings through professional upgrades. Whether you’re looking for quick wins or planning a more comprehensive approach to reduce heating bills, you’ll find actionable steps below.
The seven methods we cover have helped countless homeowners and landlords across Sussex and Surrey lower their energy consumption and monthly outgoings. Let’s explore each one.
| Method | Difficulty | Cost | Potential Saving |

| Smart thermostat | Easy | Moderate | 10-15% annually |
| Seal draughts | Very easy | Low | 5-10% annually |
| Boiler servicing | Professional | Low | 5-8% annually |
| Bleed radiators | Easy | Very low | 5-10% annually |
| Radiator foil | Very easy | Very low | 3-5% annually |
| Energy-efficient boiler | Professional | High | 20-30% annually |
Install a Smart Thermostat to Cut Energy Waste
A smart thermostat gives you precise control over when and how much your heating runs. Instead of manually adjusting the temperature or leaving your boiler on all day, a smart device learns your routine and adjusts automatically.
Smart thermostats use geofencing technology to detect when you leave home and automatically reduce heating. When you’re away, the system turns down to a lower temperature, then warms the house before you return. This alone prevents wasting energy heating an empty property.
Similarly, many smart thermostats allow remote control via smartphone. You can turn heating on or off from anywhere, which proves invaluable if you’ve left home and forgotten to adjust the thermostat. The holiday mode feature keeps pipes safe while you’re away without heating the entire house unnecessarily.
Most smart thermostats integrate with existing boilers without requiring replacement. Installation typically takes under an hour, though professional setup ensures optimal performance.
The real benefit emerges over time. Homeowners who switch to smart heating control often report that the device pays for itself within 18-24 months through reduced energy bills. For landlords managing multiple properties, remote control becomes especially valuable for preventing tenant complaints about heating and reducing emergency call-outs.
Seal Draughts Around Doors and Windows
Heat escapes through tiny gaps around doors and windows far more than most people realise. Even small cracks let warm air drift out, forcing your boiler to work harder to maintain temperature.
Self-adhesive draught excluder tape is the quickest fix. The foam compresses to seal uneven gaps and stays in place for years. Simply clean the frame, peel and stick the tape around the perimeter, and you’ve immediately reduced heat loss. This costs almost nothing but delivers noticeable improvements in room temperature.
For external doors, draught excluder tape rated as weather-resistant performs better than standard foam. For windows, the same principle applies: seal the frame where air leaks through, not the glass itself.
Draught excluder foam degrades over time, typically lasting 3-5 years before needing replacement. Check seals annually, especially on external doors exposed to weather.
The cumulative effect of sealing all doors and windows in a property can reduce heating bills by 5-10% annually. Combined with other methods in this guide, the savings compound. Landlords should prioritise this maintenance task before winter, as it prevents tenant complaints about cold properties and reduces heating-related emergency calls.
Boiler Servicing Benefits for Long-Term Savings
An annual boiler service keeps your heating system running at peak efficiency. Over time, boilers accumulate dust and sediment inside, which forces them to work harder and consume more gas to reach the desired temperature.
During a professional service, a Gas Safe registered engineer cleans internal components, checks pressure and flue gas levels, and identifies any developing faults. A well-maintained boiler uses less fuel to produce the same heat output, directly reducing your bills.
The Apex Gas & Heating Ltd annual service includes a full safety check alongside efficiency improvements. Regular servicing also maintains your boiler’s warranty, many manufacturers void coverage if annual maintenance isn’t documented.
A boiler that hasn’t been serviced in 3+ years typically uses 5-8% more gas than one serviced annually. That efficiency loss translates directly to higher bills every month.
Beyond cost savings, servicing catches problems early. A small fault detected during routine maintenance costs far less to fix than an emergency breakdown in winter when engineers charge premium rates. For landlords, documented annual servicing satisfies legal obligations under Gas Safety Regulations and provides evidence of proper maintenance if disputes arise.
Bleeding Radiators Guide to Improve Efficiency
Radiators that contain trapped air don’t heat properly, even when your boiler is working correctly. You’ll notice cold patches at the top of a radiator or entire radiators that stay lukewarm. This is air trapped inside preventing hot water from circulating fully.
Bleeding a radiator (releasing trapped air) takes minutes and costs nothing. You’ll need a radiator bleed key, available from any DIY store. Turn off your heating, locate the bleed valve (a small square socket at the top of the radiator), insert the key, and slowly turn it anticlockwise. You’ll hear a hiss as air escapes. Once water begins dripping, close the valve.
Repeat this for every radiator in your home, starting with those furthest from the boiler. Bleeding radiators improves heat distribution and allows your system to reach desired temperatures more quickly, reducing the time your boiler needs to run.
Homes with radiators installed more than 5 years ago, especially those where some radiators heat more slowly than others.
This simple maintenance task delivers measurable improvements in heating efficiency. Combined with boiler servicing, bleeding radiators ensures your entire heating system operates as designed. Many homeowners notice warmer rooms within hours of completing this task.
Use Radiator Reflector Foil on External Walls
Radiators mounted on external walls lose heat directly through the masonry to the outside. Reflector foil bounces radiant heat back into the room instead of letting it escape through the wall.
The foil reflects up to 95% of radiant heat, meaning more warmth stays inside where you need it. Installation is straightforward: clean the wall behind the radiator, cut the foil to size, and attach it with the adhesive backing or magnetic strips. The foil sits between the radiator and the wall, invisible once installed.
This method works best on external walls where heat loss is greatest. Internal radiators benefit less, though reflector foil still improves efficiency slightly. For maximum effect, combine reflector foil with other methods like draught sealing and smart thermostats.
The investment is minimal, but the cumulative savings across multiple radiators add up. Landlords should prioritise external wall radiators, as these represent the biggest heat loss in most properties.
Upgrade to an Energy-Efficient Boiler
Older boilers (pre-2005) operate at 70-80% efficiency, meaning 20-30% of the gas you pay for is wasted. Modern condensing boilers achieve 90%+ efficiency, converting nearly all fuel into usable heat.
Upgrading to an energy-efficient boiler delivers the largest long-term saving of any method in this guide. A new energy-efficient boiler cuts gas consumption by 20-30% compared to an older system. For households spending several hundred pounds annually on heating, this translates to substantial year-on-year savings.
Modern boilers also include smart controls and wireless connectivity, allowing integration with smart thermostats for additional efficiency gains.
A boiler replacement is a significant upfront cost, but the fuel savings typically recover the investment within 7-10 years, after which you’re saving pure money on heating.

Conclusion
Reducing your heating bills doesn’t require choosing between comfort and cost. The methods above, from simple draught sealing to professional boiler servicing, work together to lower consumption and monthly outgoings.
Frequently Asked Questions
Does regular boiler servicing help reduce energy consumption?
Yes. An annual boiler service ensures your heating system operates at peak efficiency by cleaning internal components, checking pressure, and analysing flue gas. A well-maintained boiler uses less gas to reach your desired temperature, directly reducing heating bills. Professional servicing also identifies worn parts before they fail, preventing costly breakdowns and maintaining your manufacturer’s warranty. Many homeowners see measurable savings within the first year of regular maintenance.
How much can I save by installing a smart thermostat?
Smart thermostats reduce heating bills by preventing energy waste through geofencing, scheduling, and room-by-room control. By turning your heating down when you’re away and adjusting temperatures automatically, many households report meaningful reductions in gas consumption. The actual saving depends on your current heating habits and home size, but the investment typically pays for itself within one to two years. Many smart thermostats provide energy reports so you can track your progress.
What is the most effective way to reduce heating bills in older homes?
Older homes lose heat through draughts, poor insulation, and inefficient boilers. Start by sealing gaps around doors and windows with draught excluder tape, then use radiator reflector foil on external walls to bounce heat back into rooms. Next, arrange a professional boiler service to ensure your system runs efficiently. If your boiler is over 15 years old, upgrading to a modern energy-efficient model will deliver the biggest long-term saving. These steps address the main sources of heat loss in period properties.
Are there simple DIY draught-proofing methods for residential properties?
Yes. Self-adhesive foam draught excluder tape is the quickest DIY solution, simply clean the frame, measure the gap, cut the tape to length, and press it firmly into place around doors and windows. Radiator reflector foil is equally straightforward: cut it to size and stick it behind radiators on external walls. Both are inexpensive and take minutes to install. For larger gaps or professional-quality results, a qualified heating engineer can assess your property and recommend additional measures tailored to your home’s specific needs.
