FAQs
How often should I service my boiler?
Every 12 months — it’s essential for safety and efficiency. You can pair this with an annual boiler efficiency check to ensure optimal performance.
Do landlords have to service boilers annually?
Yes. A yearly Gas Safety Certificate (CP12) is a legal requirement — and can often be combined with boiler installation or replacement services.
Is a boiler service the same as a gas safety check?
Not exactly. A service is more detailed and includes cleaning and efficiency tests in addition to safety checks. Both are essential for maintaining insurance validity and long-term boiler health.
