Proof point

£4,000 / month saved on one of our site optimisation projects.

On a recent site optimisation project for a commercial client we identified over £4,000 per month in avoidable spend — recovered through sub-metering, monitoring & targeting, and control-strategy optimisation. BMS isn't just about comfort; run properly it pays for itself.

FAQs

Straight answers,before we speak.

Anything not covered here? Call us on 07500 040578.

How quickly do you respond to a BMS call-out?+

Our phones are answered 24/7, 365. For contracted clients we guarantee response times per SLA — typically on-site within two hours, including out-of-hours. Reactive, non-contract call-outs receive a response within 24 hours.

Which protocols and systems do you support?+

We work with open, vendor-independent protocols including BACnet, Modbus, KNX, LON and M-Bus. Through our partnership with Forest Rock we supply and integrate products from ABB, Distech Controls, Mitsubishi Electric, Tridium (Niagara), iSMA Controlli, Phoenix Contact and others.

Do you offer PPM contracts and remote monitoring?+

Yes. Planned Preventive Maintenance contracts are offered with defined SLAs, and remote monitoring / remote access is available so we can diagnose and resolve issues before they become site visits.

How is pricing structured?+

BMS work is bespoke and project-based, so we don't publish 'from' prices. Send us the specification, drawings or a brief description of the site and we'll come back with a written quote — quote on application.

Do you work direct or as a subcontractor to M&E contractors?+

Both. A significant portion of our work is subcontracted M&E delivery under formal contract, and we also work directly with end clients — landlords, facilities teams, healthcare trusts and building owners.

What warranty do you provide on installations and panels?+

A one-year workmanship warranty is standard on installations and panels, in addition to the underlying manufacturer warranties on supplied equipment.
