TM44 Inspection Report & Certificate — What You Receive from AirCert

What is a TM44 Certificate and Why Does Your Business Need One?

A TM44 certificate is the official compliance document confirming that your commercial air conditioning system has been professionally assessed by an accredited inspector under the Energy Performance of Buildings Regulations 2012. For any building in England and Wales with air conditioning systems totalling 12kW or more, holding a valid TM44 certificate is not optional — it is a legal requirement. Failure to hold one can result in financial penalties of up to £300 per system and can seriously complicate property transactions.

AirCert issues TM44 certificates to commercial buildings across Middlesbrough, Teesside, and the wider North East and Yorkshire region. Every certificate we produce is issued by Tom, who holds both Elmhurst Level 3 and Level 4 accreditation — the highest qualifications available for air conditioning inspections in the UK. This means your TM44 certificate covers every system type, from a single split unit in a small office to a complex multi-zone VRF installation in a large commercial building.

What Your TM44 Certificate Includes

Every TM44 certificate issued by AirCert comes with a full technical report. The certificate itself confirms legal compliance — it includes the property address, inspection date, system details, the inspector’s accreditation reference, and a unique certificate number. It is lodged on the national register immediately, making it instantly verifiable by enforcement officers, solicitors, surveyors, and anyone else who needs to confirm your compliance status.

The accompanying report is where the real value lies. Rather than a certificate that simply ticks a regulatory box, AirCert reports are written in plain English and provide genuinely useful information about your systems’ efficiency and condition. Recommendations are practical and prioritised — not a generic list of theoretical improvements but specific, actionable guidance relevant to your particular installation.

Your report will typically cover:

• System inventory — a complete record of all air conditioning equipment including type, capacity, age, and manufacturer details
• Component assessment — inspection of indoor units, outdoor condensers, pipework, insulation, and drainage
• Efficiency evaluation — analysis of how well the system is performing against current standards and its original specification
• Maintenance review — assessment of servicing history, filter condition, and overall system care
• Controls analysis — review of timers, thermostats, zoning effectiveness, and any building management system integration
• Prioritised recommendations — clear guidance on improving efficiency, reducing running costs, and addressing any compliance concerns

Who Can Legally Issue a TM44 Certificate?

Only inspectors accredited by an approved scheme can legally produce a TM44 certificate. This is a crucial distinction that many building owners overlook. Your HVAC maintenance contractor, however experienced, cannot issue a legally valid certificate unless they also hold specific TM44 accreditation through a body such as Elmhurst Energy. A document produced by an unaccredited inspector is worthless from a compliance perspective, regardless of how professional it appears.

AirCert holds dual Elmhurst Level 3 and Level 4 accreditation. Level 3 covers standard systems — splits, multi-splits, packaged units, and fan coils. Level 4 extends to complex installations including VRF and VRV systems, chilled water plant, and large centralised cooling infrastructure. Many inspectors hold only Level 3, which means they cannot legally inspect and certify more complex systems. With AirCert, one inspector covers everything.

The National Register: Your TM44 Certificate Is Permanently Recorded

Every TM44 certificate AirCert issues is registered on the national database operated under the UK government’s building compliance framework. This provides a secure, permanent record that cannot be altered or lost. It allows enforcement authorities, solicitors, and property professionals to verify your certificate quickly and independently — without relying on you to produce a paper copy.

This registration is particularly important during property transactions. Solicitors and surveyors increasingly request evidence of a valid TM44 certificate as part of commercial property due diligence. Buildings without a registered certificate can face delays or complications at the point of sale or lease renewal. Having a current, registered certificate in place removes this risk entirely.

How Long is a TM44 Certificate Valid?

A TM44 certificate is valid for five years from the date of inspection. After five years, a new inspection and certificate are required to maintain compliance. If your system undergoes significant changes — major capacity additions, new system installations, or substantial upgrades — it is worth considering whether a fresh inspection is needed before the five-year renewal date, as the original certificate may no longer accurately reflect your systems.

Keeping track of your certificate’s expiry date is straightforward — it is printed on the certificate itself and visible on the national register. AirCert can also send renewal reminders to ensure you never find yourself out of compliance inadvertently. Many of our clients across the North East and Yorkshire set up repeat inspections on a five-year cycle, removing compliance management from their to-do list entirely.

TM44 Certificate for Property Sales and Lease Renewals

One of the most common situations that prompts urgent TM44 certificate requests is a commercial property transaction. Buyers, lenders, and their legal teams increasingly scrutinise compliance documentation as part of due diligence, and a missing or expired TM44 certificate can stall a sale or complicate lease negotiations at the worst possible moment.

AirCert regularly handles urgent inspection requests for clients facing transaction deadlines. In most cases we can schedule an inspection within a few days and issue the certificate promptly after completion. If you are aware of an upcoming sale, purchase, or lease renewal, the sensible approach is to check your certificate status well in advance rather than waiting for a solicitor’s enquiry to reveal a compliance gap.

TM44 is Not a Pass or Fail Test

A common misconception is that a TM44 inspection could result in a building “failing” and being denied a certificate. This is not how it works. A TM44 certificate is issued following every compliant inspection regardless of the system’s condition or efficiency. The inspection produces an objective assessment, and the accompanying report identifies recommendations — some essential, some advisory — but the certificate itself confirms that the inspection has taken place, not that the systems passed a test.

This means there is no reason to delay arranging an inspection out of concern about what it might reveal. The certificate you receive is valid whether your systems are in excellent condition or in need of attention. The report simply tells you where improvements would be worthwhile — information that is valuable regardless of the compliance obligation.
