As a general rule, your boiler should be serviced once a year by a Gas Safe registered engineer. Most manufacturers also make an annual service a condition of keeping the warranty valid, so skipping it can quietly cost you down the line.
A proper service is more than a quick look. We start with a central heating system water test (checking pH, corrosion and inhibitor levels) and top up the inhibitor where needed. We then clean the condensate trap and system filter, and run the boiler's combustion and safety checks so you know it's burning cleanly and safely.
The best time to book is late summer or early autumn, before the heating goes on in earnest. Booking ahead of the cold snap means any small issues are caught while they're cheap to fix, rather than turning into a breakdown in the middle of winter.
If you let a rental property, you'll also need an annual Landlord Gas Safety Certificate (CP12) for each gas appliance. We provide these across the New Forest. Get in touch and we'll help keep you on the right side of the regulations.
