Every UK ventilation system must be classified as high, medium or low, in accordance with The Building & Engineering Services Association’s TR/19 Guide to Good Practice. This determines the intervals at which ventilation ductwork must be cleaned. We provide cost effective, fully certified professional cleaning which complies fully with TR/19. Keeping your property compliant on legionella control, ductwork cleaning and vital fire safety cleaning is essential.
