Full Commercial Maintenance

We are able to provide a complete service ideal for schools and commercial businesses. We can do full boiler room refurbishments and upgrades. Whether it be a single component in the boiler room or a full system upgrade, we can offer both. We can also deal with general plumbing issues, breakdowns and refurbishments.


Boiler servicing, which would also include a boiler room health check. This consists of checking operation of pumps, motorised valves, expansion vessel pressure and recharge if necessary, testing of any safety interlock systems, basic run through of BMS system, a clean up of the boiler room and general inspection. Service sheets would be issued on completion, and a report of any defects noted, or any system improvement recommendations that can be made.

HWS Cylinders

Drain down and inspection of HWS cylinders  – We would open up the inspection hatch and chemically descale if necessary.  –  if there is no inspection hatches then a blow down or a pasteurisation can be done to remove any sludge at the base of cylinder.  Before and after photos and a certificate will be provided to go in the school legionella folder.


Cleaning fan convector heaters. We will open heaters up and give a thorough clean up including all filters, and impellers resulting in cleaner air circulation, rather than dust being blown around and recirculated.  A deeper clean can also be offered which involves using an air compressor to blast through the heat exchanger which again massively improves the operation of the heater.

Thermostatic Mixing Valves

Servicing thermostatic mixing valves. Each blending valve would be stripped apart and serviced which involves , cleaning filters, checking non return valves, chemically descaling the working parts and cartridges. They will be set between 38-40 degrees or 37 in very young children areas or disabled. A certificate would be issued on completion for the schools legionella file and a report of any defective valves.

Commercial Services


Creating a easy to use file for the school instead of the massive in depth legionella file. Would include – Daily tasks, weekly tasks, monthly tasks, quarterly tasks, 6monthly tasks, annual tasks.

May be as little as ticking a box to say they have flushed a low use outlet to having a full system chlorination.

Chlorinating water tanks and system pipework. Tanks will be thoroughly cleaned and chlorine added. We would then pull around system pipework and re dose the tank. After one hour we would neutralise the water tank and flush the system pipework. On completion we would take water samples and have them analysed by an independent company who will give us the results. Then we would issue the school with a certificate for their legionella file.


Monthly water temperature testing. Each month we would take temperature readings from the nearest and furthest taps  from a cylinder or cold water storage tank, plus 10% of all other areas. We would report any taps that did not meet the required temps in the required time. (50 degrees or above in 1 min for hots  and 20 degrees or below in 2 mins for colds). Every 4 months we would look back at the readings and investigate what can be done to improve any readings that did not meet the requirements. Would require us to go to site first and carry out full site survey and create our own record sheets.

Site Tests

Whole site gas tightness testing  – we would calculate the size of the system pipework and meter volumes. If the installation is over  1 cubic meter,  then we would break it down in size and carry out 2x tests. We would issue a gas certificate on completion for the schools files.



Unblocking science lab gas taps and lab tightness testing. Once all taps have been unblocked/repaired, we would carry out a full tightness test on each individual lab. Any leaks would be repaired straight away. We would then issue a certificate for each individual lab and a report.



Descaling instantaneous water heaters/ tea machines/ tea urns.  We would remove as much loose scale as possible and then chemically descale the more stubborn build up. Units will be thoroughly flushed on completion.
