Your boiler keeps your home warm and your showers hot, but without proper care, it can falter. Fortunately, these boiler maintenance tips can help UK homeowners avoid breakdowns, cut energy costs, and extend their system’s life. At JJK Gas Services, we’ve seen how simple upkeep makes a big difference. In this guide, we’ll share practical advice to keep your boiler running smoothly all year round.
Why Boiler Maintenance Matters

A well-maintained boiler doesn’t just heat your home – it saves you money. Regular care boosts efficiency, reducing energy bills by up to £350 annually, according to the Energy Saving Trust. Plus, it lowers the risk of sudden faults or dangerous carbon monoxide leaks. Ready to take control? Let’s explore the best boiler maintenance tips.
Essential Boiler Maintenance Tips for Every Home

These boiler maintenance tips steps are straightforward and effective. Follow them to keep your heating system in top shape.
1. Schedule an Annual Service
Start with a professional check-up. A Gas Safe registered engineer can spot issues like worn parts or blockages. At JJK Gas Services, our boiler servicing ensures your system runs safely and efficiently. Book before winter for peace of mind.
2. Bleed Your Radiators Regularly
Air trapped in radiators reduces heat output. Grab a radiator key, open the valve, and release the air until water drips out. This quick task improves circulation and keeps your home cosy.
3. Monitor Boiler Pressure
Check the pressure gauge – it should sit between 1 and 1.5 bars when cold. Too low? Use the filling loop to top it up (see your manual). If it keeps dropping, call our repair team to investigate.
4. Insulate Exposed Pipes
Frozen pipes can halt your boiler in winter. Wrap them in foam lagging, especially in unheated areas like lofts or garages. This simple step prevents costly damage.
5. Run Your Boiler Occasionally
Even in summer, turn on your heating for 10–15 minutes monthly. This stops pumps and valves from seizing up. It’s an easy way to avoid big repair bills later.
6. Listen for Unusual Noises
Banging, gurgling, or whistling? These could signal limescale or a failing component. Don’t wait – get it checked by an expert to avoid worse problems.
7. Fit a Carbon Monoxide Detector
Safety comes first. Install a detector near your boiler to catch any leaks of this silent killer. Pair it with regular maintenance for full protection.
Seasonal Boiler Care: Winter vs. Summer
Your boiler’s needs change with the seasons. Here’s how to adjust:
- Winter: Run it regularly, insulate pipes, and watch for frozen condensate pipes. Thaw them with warm water if needed.
- Summer: Give it a rest but don’t let it sit idle too long. A short burst keeps parts moving.
