We detect "silent killer" CO leaks that are invisible, odorless, and potentially fatal.
Verify Combustion:

This responsibility involves a mandatory annual obligation to have an inspection by a Gas Safe registered engineer. Whether you manage a single conversion or a multi-unit property portfolio, the law holds you personally accountable for the gas safety and well-being of every occupant in the premises.
- Your Liability: Failure to provide a valid, annual CP12 is a criminal offense, resulting in unlimited fines, possible imprisonment, and rendering a Section 21 eviction notice invalid.
- Our Role: We act as your accredited professional partner, providing the technical expertise and rapid certification required to fulfill your mandatory duty of care. We also provide EICR for Landlords and Fire Risk Assessments for complete landlord compliance.
