Domestic Legionella Risk Assessments - £65.00 + vat


Landlords of residential/domestic type accommodation (housing, flats etc) have legal responsibilities for combating and preventing legionnaires disease. Health and safety legislation requires that landlord's carry out legionella risk assessments for the legionella bacteria which causes the potentially fatal legionnaires' disease.


Most Domestic rented premises' will be low risk but as it is a potentially fatal pneumonia type disease it is important that you risk assess your rented residential premises.
