Prepare Your Boiler for Autumn: A Selsey Homeowner's Checklist

Why Late Summer Is the Best Time to Service Your Boiler

It might seem odd to think about your heating while the weather is still warm, but late August is the ideal time to get your boiler serviced in Selsey. Once autumn arrives and temperatures drop, heating engineers across the Manhood Peninsula get flooded with calls — often from people whose boilers have broken down after months of inactivity.

By booking your annual service now, you avoid the autumn rush, get a convenient appointment time, and ensure your boiler is running safely and efficiently before you actually need it. A boiler that has sat idle all summer can develop issues that only become apparent when you switch it on for the first time in October — by which point you may be waiting days for an engineer.

Turn Your Boiler On Before You Need It

One of the simplest things you can do is turn your heating on for 15-20 minutes during late summer. This lets you check that the boiler fires up correctly, the radiators get warm, and there are no unusual noises. If you notice any issues — such as the boiler not igniting, pressure dropping, or cold spots on radiators — you have time to get them fixed before the cold weather arrives.

Do not wait until the first frosty morning in October to discover your boiler is not working. By then, every heating engineer in Selsey and Chichester will be booked up for days.

Check Your Boiler Pressure

Your boiler pressure should sit between 1 and 1.5 bar when the system is cold. If it has dropped below 1 bar over the summer, your boiler will not operate efficiently and may stop working entirely. You can repressurise it yourself using the filling loop, but if the pressure keeps dropping after you top it up, there is a leak somewhere in the system that needs professional attention.

Low pressure is one of the most common reasons boilers fail to fire up in autumn. Checking it now gives you time to arrange a repair before you actually need the heating on.

Bleed Your Radiators

If your radiators are cold at the top when the heating is on, they have trapped air inside. Bleeding your radiators releases this air and allows hot water to fill the entire radiator, improving heat output and efficiency. This is a straightforward DIY job — just make sure the heating is off and the radiators are cool before you start.

If you notice cold spots at the bottom of your radiators rather than the top, that is a sign of sludge build-up in the system, which may require a powerflush. We carry out powerflushing across Selsey and the Manhood Peninsula to restore full heat output.

Book Your Annual Service Now

An annual service by a Gas Safe registered engineer is essential for safety, efficiency, and warranty validation. During a service, we check the gas pressure and flow, inspect the flue and ventilation, test safety devices, clean key components, and ensure the boiler is burning gas efficiently.
