TMV Servicing for Nottingham properties
Thermostatic mixing valves protect vulnerable people from scalding, but they also create a section of warm pipework downstream where bacteria can grow. TMVs need regular servicing to make sure they still fail safe, deliver the right temperature and are free from scale and debris.
Water in Nottingham is moderately hard to hard. Hard water leaves scale on TMV strainers, filters and check valves, so valves here can drift out of calibration faster and benefit from more frequent servicing.
Nottingham's large student housing sector in Lenton and Beeston, Lace Market conversions and city-centre offices are typical of the properties where we carry out risk assessments and monitoring.

How often
Manufacturers and HSG274 recommend in-service tests at least annually. Healthcare settings following HTM 04-01 may need a performance check at six to eight weeks after commissioning and then a frequency set by the results.
Legislation in England
In England, legionella duties come from the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999 and COSHH 2002, with HSE's ACoP L8 and HSG274 setting the standard. Enforcement is by HSE or the local authority, depending on the premises.
In Nottingham, legionella law is enforced by Nottingham City Council's environmental health team for offices, shops, hotels, restaurants and leisure premises, and by HSE for factories, warehouses, hospitals, schools and council-run premises. We cover all NG postcodes in and around Nottingham.

Is TMV servicing a legal requirement?
There is no law that names TMV servicing, but duty holders must control the risks of scalding and legionella, and HSG274 and manufacturers expect TMVs to be tested and maintained. In healthcare, HTM 04-01 sets the expectation.
What is the difference between TMV2 and TMV3?
TMV2 valves are certified for domestic use. TMV3 valves meet the more demanding NHS specification for healthcare and care settings.
