One coordinated scope for complex HVAC estates.

Where a coordinated programme can be valuable

Multi-building office estates, hotels, university campuses, shopping centres, mixed-use facilities and managed commercial portfolios can have separate chillers, VRF equipment, rooftop plant and tenant systems. The commercial value is in agreeing a coherent asset list, sensible access sequence and accountable deliverables rather than selling a one-size-fits-all certificate.

A project may involve multiple visits and contractors. We assess that possibility case by case; we do not claim confirmed nationwide availability, an in-house engineering fleet or a single trade qualification for every activity.

Four distinct service workstreams

1. TM44 energy inspections: check effective rated cooling output, current inspection evidence, correct accredited energy assessor and applicable register lodgement.
2. F-Gas and refrigerant compliance: establish refrigerant type, charge, records and potential leak-check obligations; regulated work requires suitable personal and company certification.
3. HVAC technical works: define preventative maintenance, repair, plant condition review or replacement as separate priced mechanical-engineering tasks carried out by verified competent providers.
4. Building energy documentation: identify when separate EPC, DEC or MEES support may be relevant and refer this specialist search journey to the existing CODEEX MEES service rather than confusing it with a TM44 report.

No part of a TM44 energy inspection certifies refrigerant containment, maintenance condition, statutory EPC status or completion of repair work.

How a large-scope commercial enquiry is assessed

Start with the managing organisation, number of buildings, approximate locations, accessible equipment schedule, existing reports and actual decision deadline. We then separate legally required inspections from optional maintenance and determine which qualified firms may be available for each part. A written scope should identify assumptions, exclusions, dependencies, staged delivery and the evidence supplied.

• Number and geographic spread of premises, including individual addresses.
• Available model, capacity and refrigerant inventory, with unknowns marked UNKNOWN.
• Report and inspection history, renewal dates and any portfolio gaps.
• Access constraints, plant-room permits, shutdown restrictions and responsible site contacts.
• Procurement and invoicing requirements, including PO and staged delivery expectations.

For substantial estates, scoping may require a paid technical survey before an accurate fixed quotation is possible. Any pricing, project duration or availability is confirmed in writing only after competent subcontractor verification.

Commercial deliverables and control points

A properly agreed programme can include a building-by-building evidence tracker, separate inspection scopes, documented subcontractor responsibilities, staged site access, reports and applicable register references, and a list of recommended follow-up works. These are proposed scope components, not guaranteed outputs until confirmed in a quotation.

The responsible person retains statutory obligations. A missing report or uncertain installation is recorded for human assessment, not automatically given a compliant/failed label. The TM44 desk does not represent itself as a government register.

Regulatory references

England and Wales TM44 inspections and F-Gas leak checks operate under separate rules. Current duties should be checked against official guidance and the installed equipment; Scotland and Northern Ireland may differ.
