    Penalties for non-compliance

    Failing to have a valid Gas Safety Certificate is a criminal offence carrying fines up to £6,000, up to six months imprisonment, and likely invalidation of your landlord insurance. There is no grey area.

    Tracking across multiple properties

    LandlordSorted's compliance tracker covers Gas Safety, EICR, EPC, smoke alarms, and HMO licences in one dashboard with email reminders at 90, 60, or 30 days. The free plan includes the full tracker. You also need to stay on top of MTD tax compliance — LandlordSorted handles both.
