How long is each landlord certificate valid?

The calculator uses the standard validity periods for England. These are the renewal intervals every private landlord needs to plan around.

Certificate	Valid for	Who issues it
Gas Safety (CP12)	12 months	Gas Safe registered engineer
EICR (electrical)	Up to 5 years	Qualified electrician (NICEIC / NAPIT)
EPC	10 years	Accredited domestic energy assessor
Legionella risk assessment	Review ~every 2 years (no fixed legal period)	Competent person or assessor

A renewed certificate runs from the date of the new check, not from the old expiry date. Booking a month early does not shorten your cover, so it is good practice to rebook before expiry rather than on the day.

What about smoke alarms and deposit protection?

Two important obligations are not date-based, so they are not in the calculator. Smoke and carbon monoxide alarms must be tested at the start of every new tenancy rather than on a fixed cycle. A tenancy deposit must be protected in a government-approved scheme within 30 days of receiving it. Both still matter, they just are not renewal dates. The full picture is in our UK landlord compliance checklist.
