Environments we work in

Different buildings fail in different ways. Knowing which risk matters most is the difference between a system that copes and one that doesn't.

How it works

From assessment to planned maintenance

STAGE 01

Assessment

A full survey of the building, existing plant and load requirements, with access and compliance constraints identified up front.

STAGE 02

Proposal

A specification, drawings where required, and a costed proposal covering equipment, works, programme and expected running costs.

STAGE 03

Installation

Works programmed around your trading hours by directly employed engineers, with commissioning data and O&M documentation on handover.

STAGE 04

Maintenance

A planned maintenance agreement, asset register, service reports and statutory F-Gas records kept current on your behalf.

Compliance

The paperwork is part of the job

If you operate equipment containing fluorinated gases you are legally required to hold leak-test records, log refrigerant movements and use certified engineers. Most businesses we take on have gaps in that file.

We audit what you have, close the gaps, and keep the records current from then on, so an inspection, an insurance review or a lease negotiation is a filing exercise rather than a scramble.

Refrigerant logs and reconciliation
HACCP temperature records
Decommissioning and recovery certificates
O&M manuals and as-built drawings

"Walk-in went down on a Saturday night. Engineer was there in ninety minutes and we opened Sunday as normal."

Dan K., restaurant group, London

"Took over the contract on eleven sites. First thing they did was fix the paperwork the last lot had never done."

Facilities manager, retail estate, Cambridgeshire

"They specified for our peak load, not the average. Two summers in and the office has never been the problem."

Office manager, professional services, Cambridge
