💬 Questions about boiler service costs

How often should I have my boiler serviced?

Once a year is the usual advice, and many makers need it to keep the warranty valid. Book before winter, when engineers in London are busiest.

Is a boiler service the same as a gas safety check?

A service looks at how well the boiler runs. A landlord's gas safety record is a separate certificate. Say which one you need when you request quotes.

Why does it have to be a Gas Safe registered engineer?

It's the law: only Gas Safe registered engineers can work on gas boilers. Ask to see their Gas Safe card and check the number on the register.

Is a yearly boiler service worth paying for?

Usually yes. It can spot a small fault before it becomes a breakdown, and many makers need a yearly service to keep the warranty valid.
