CMS is a brand new company with a lifetime’s experience in servicing, installing and refurbishing unvented cylinders for all manufacturers.

We will work on any cylinder you may have in your home or business premises, domestic or commercial.

We work closely with large landlords and housing authorities including the National Health Service, and sheltered housing schemes.

So if you’re a home owner or a large landlord you’re in safe hands with CMS.

Our engineers

All our engineers are trained and approved by CMS manufacturers. We do not use unauthorised engineers.

Our approved engineers are all fully trained in all aspect of the job. Both the G3 regulations and our leading manufacturer’s requirements and product range.

We handle warranty and service contracts for a number of high end unvented cylinder manufacturers, having satisfied their individual criteria and high standards of installation and customer services with our; one job, one visit approach.

Our training facility

Following a review of the constant misgivings that occur out in the field of service and maintenance our group of manufacturer’s feel it is no longer acceptable to rely on the training courses alone, that are readily available throughout the U.K. with regards to unvented and vented mains pressure cylinders.

Customers and end users are often falling fowl of warranty and guarantee issues due to a lack of knowledge or application by individuals operating within the industry.

What is the way forward?

CMS; are proud to launch their training facility which will provide an insight into what the manufacture and benchmark auditors expect to be completed and understood by the installation engineer or servicing engineer when commissioning, servicing or installing their individual cylinders.

CMS; are here to provide a valuable link between manufacturer and site engineers, creating an onsite confidence that can only come through close product understanding in a hands on environment by individuals who have been out in the field so that all bases are covered in this comprehensive training facility.

CMS; will annually call in its approved engineers to update them on manufacturer’s developments.

CMS; will also carry out on site assessments to ensure our high standards are being employed on every job. A CMS engineer will also enjoy technical back up 24/7.


CMS; issue all there approved engineers with a unique operative number relating solely to a single individual to avoid any confusion when dealing with the general public. This provides direct accountability and responsibility of the engineer placing him above the average plumber in accuracy and understanding of our manufacturer’s entire product range and installation requirements.

CMS; also offers an exclusive quality PPE and Work Wear range at a discounted price to all its approved installers, again this places them in a league above their nearest rivals in their local areas identifying them as Approved by the manufacturer themselves so the more prudent client will want to do business with only an approved registered engineer, wouldn’t you?

CMS approved engineers can also get access to discounted genuine parts via our website.
