Thameside Mechanical Services limited are specialist commercial heating, gas, plumbing and pipework contractors. 


We undertake installation, service and repair projects for a wide range of clients.


Based in Tollesbury, Essex, we are ideally located to serve the South East quarter of England with London and the City in one direction and North Essex, Suffolk and beyond, in the other. 

We have been in continual business for over 30 years and were founder members of 'CORGI' (the predecessor of the modern 'Gas Safe Register'). 

The company remains family-owned and managed and we have built our reputation providing high quality engineering services supported by personal touch management and close attention to detail.


We are fully insured, are registered for commercial gas work with Gas Safe Register, are 'water industry approved plumbers' (WIAPS/Water Safe scheme) and we are registered with 'Constructionline'.
