Servicing Is Year-Round, Not Just Annual

While a full professional service only needs to happen once a year, a handful of small checks spread across the seasons can catch problems early, keep your system efficient, and make that annual service go far more smoothly.

Why a Schedule Helps

Boiler faults rarely appear out of nowhere — they build up gradually. A seasonal routine means you're far more likely to notice a small issue before it becomes an expensive one.

‍

Spring: Post-Winter Check

Winter puts your boiler under the most strain all year, so spring is the time to check how it's held up.

What to Do

• Check for any leaks or damp patches around the boiler that appeared over winter.
• Bleed radiators if any developed cold spots during heavy use.
• Note any unusual noises or performance issues to mention at your next service.

‍

Summer: Light Maintenance

With heating demand low, summer is a good time for maintenance that doesn't need the system running constantly.

What to Do

• Run your heating for 10–15 minutes monthly, even in warm weather, to keep the system moving.
• Check your boiler pressure remains within the normal range.
• Clear any debris or obstructions around external vents and flues.

Autumn: The Big Check

Autumn is when your annual professional service should happen — before the cold weather increases demand on the system.

What to Do

• Book your annual service with a Gas Safe registered engineer.
• Insulate any exposed pipework, including the condensate pipe.
• Test your thermostat and heating controls ahead of regular winter use.

Winter: Active Monitoring

Winter is when problems are most likely to surface, simply because your system is working the hardest.

1. Keep an eye on boiler pressure, especially after bleeding radiators.
2. Watch for signs of a freezing condensate pipe during cold snaps.
3. Address any strange noises or performance drops promptly rather than waiting.
4. Keep your heating on low even when out, to protect pipework.
