Why it matters

When a survey is the right call

You Don't Know What You've Got

Inherited plant rooms, incomplete maintenance records, or units that have never been formally assessed, a condition survey gives you a reliable baseline.

Budget Planning Is Guesswork

Without documented condition data, it's difficult to plan maintenance spend or justify capital requests. A survey gives you the evidence to build a credible asset programme.

Everything Is Reactive

Without a baseline condition record, every decision is reactive; you respond to failures rather than preventing them. A survey gives you the data to move from reactive to planned.

Scope of assessment

What surveys can include

We carry out surveys across all makes and models, including fault finding, condition assessment, and performance verification. Every finding is documented and all survey work is carried out on site by our engineers.

Fan condition, bearings, and motor performance
Heating and cooling coil efficiency
Filter condition and pressure drops
Damper operation and actuator function
Controls, sensors, and BMS interface
Structural casing and frame integrity
Airflow volumes vs. design specification
Internal cleanliness and hygiene assessment
Insulation condition and repair requirements

What you receive

Survey deliverables

Every survey produces a complete set of documented outputs your team can act on.

01

Photographic Condition Report

Every finding is documented with photographs and engineer notes, giving you a clear, evidence-based record of system condition.

02

Prioritised Recommendations

Findings are categorised by priority so your maintenance team can act on what matters most first. We can work within your budget and timeframes.

03

Costed Remedial Recommendations

Where works are required, we provide indicative costs alongside the findings, so you can plan budget and programme at the same time.
