“They delivered a reliable, fully commissioned plantroom that restored our heating and hot water resilience with minimal disruption.”
/ / PROOF / /
See it in practice
The work should speak for itself
The challenge
The rooftop plant was failing, with faulty burners and a system operating at half its capacity. A system failure risked shutting down key parts of the building. They needed a system built to last.
What we did
The ageing plant received a new commercial installation, including boilers, a water heater, pipework, flushing, insulation, and full commissioning and handover, managed inside a live, occupied plantroom.
The result
- A modern, maintainable plantroom in place of
equipment that had been beyond repair - Heating and hot water resilience restored
- Verified, reliable readings across every unit
- Fully commissioned boilers and water heaters

Frequently Asked
Questions
Frequently Asked Questions
What does Advantos do?
Advantos is a specialist technical services group. We deliver HVAC and mechanical, electrical, water treatment and hygiene, fabric, and maintenance and projects for commercial estates across the UK, with one standard behind every discipline.
Is Advantos a facilities management company?
Advantos is a specialist technical services provider rather than a facilities management company. We deliver the hard FM and M&E disciplines directly for asset owners and occupiers. We also work alongside FM providers wherever specialist engineering or compliance expertise is needed.
What is Engineered Visibility?
Engineered Visibility is how Advantos makes engineering work visible. Every job, photograph, approval and compliance record is brought into a single client view, so you can see what’s complete, what’s outstanding and what needs attention without having to chase an update.
What is the Advantos Standard?
The Advantos Standard is the operating model every Advantos team works to, whatever the discipline. Deliver the work properly, meet the compliance requirements, communicate clearly throughout, and record it properly. Same standard, every job, every site.
Do you provide planned preventative maintenance (PPM)?
Yes. Advantos delivers planned preventative maintenance alongside reactive works, statutory and compliance maintenance, small works and M&E projects. PPM programmes are built around the assets and compliance requirements of the individual estate.
Which sectors does Advantos work in?
Advantos works across healthcare, commercial property, retail, data centres, education and beyond. These are estates where compliance failure carries real operational and regulatory consequences, and where evidence of the work matters as much as the work itself.
Which companies are part of the Advantos group?
Four specialist businesses sit within Advantos: JD Services (HVAC and mechanical), DJ Mace (electrical), United FM (planned and reactive maintenance) and Advantos Services (wider M&E, maintenance and project delivery).
Which accreditations does Advantos hold?
Advantos is accredited across all disciplines, ensuring every job meets the industry standard.

Do you work with FM providers?
Yes. Advantos supports FM providers as the specialist technical capability behind their wider service, as well as working directly with asset owners and occupiers.
Where do you operate?
Advantos operates nationally across the whole of the UK, with higher density coverage in the Midlands, South East, London and the home counties, and the North West. We currently do not cover Ireland. Response times depend on your contract. On some sites, SLAs are as fast as 2 hours.
How quickly do you respond to reactive callouts?
We deliver reactive response within agreed SLAs. These vary by client and contract, but we can attend critical issues within two hours where needed.
What does Powered by Advantos mean?
Powered by Advantos means the people you already know stay the same. What changes is what sits behind them: wider systems, one shared standard, and the backing of the whole group.
What makes Advantos different?
Most estates don’t struggle because a supplier can’t do the work. They struggle because different suppliers do it different ways, different standards, different records, different excuses. Advantos brings mechanical, electrical, water treatment and maintenance specialists together under one group and one standard, so you get direct access to genuine experts, and proof of the work as it happens.
