When a property is left unoccupied, unchecked utilities can pose serious risks, from burst pipes in winter to fire hazards caused by live electrical systems. Marpol Security offers a professional drain down and isolation service to help mitigate these risks and maintain insurance compliance.
This service is suitable for landlords, letting agents, property managers, housing associations, and developers who need a safe and secure shutdown of vacant buildings.
