The duty

Who it applies to
Anyone who lets a property they own under a lease shorter than 7 years or under a licence (HSE landlord FAQs).
How often
Within 12 months of installation and then at intervals of not more than 12 months (regulation 36(3)(a)).
Checking early
A check done in the 2 months before the deadline is treated as done on the deadline, so the yearly date does not move (regulation 36A).
Copy to tenants
To each existing tenant within 28 days of the check, and to a new tenant before they move in (HSE landlord FAQs; GOV.UK).
Keeping the record
Until two further checks have been done, or 2 years from the last check of an appliance that is removed (regulation 36(3)(c)).
If it is not done
HSE says it will take action against landlords who do not meet their duties, which could result in a substantial fine and/or a custodial sentence (HSE landlord FAQs).

What it costs

The median published price is £64.99 across 31 UK providers (UK Gas Safety Certificate Price Index), a yearly cost for each let property.
