How often should a boiler be serviced in London?
Every 12 months — without exception. Annual boiler servicing keeps your warranty valid, maintains efficiency and is a Gas Safe requirement for rented properties.
How Often Should a Boiler Be Serviced?
Every 12 months — this is the universal recommendation from boiler manufacturers, Gas Safe Register and the Health & Safety Executive.
Why Annual Servicing Matters
- Warranty validity — most boiler warranties require annual servicing by a Gas Safe engineer to remain valid.
- Efficiency — a serviced boiler burns fuel more efficiently, reducing energy bills.
- Safety — carbon monoxide leaks are most commonly found during routine servicing, not emergency callouts.
- Longevity — annual maintenance prevents small issues from becoming expensive failures.
- Legal requirement for landlords — under Gas Safety (Installation & Use) Regulations 1998, all gas appliances in rented London properties must be annually inspected by a Gas Safe engineer.
