TM44 Inspection Penalties: What Happens If You Don’t Comply?
Understanding TM44 Inspection Penalties and Why Compliance Matters
TM44 inspection penalties start at a £300 fixed charge for failing to hold a valid certificate, can be repeated weekly until you comply, carry a separate £200 fine for failing to produce documentation within seven days, and can accumulate to more than £5,000 in total. Despite this, many building owners and facilities managers across the North East remain unaware of the consequences of non-compliance. This guide explains exactly what TM44 inspection penalties apply, how enforcement works in practice, and what you can do right now to protect your business.

If you are unsure whether your building requires a TM44 inspection in the first place, our detailed guide on what a TM44 inspection involves covers the fundamentals. If you already know the requirement applies and want to understand the risk of ignoring it, read on.
The Legal Basis for TM44 Inspection Penalties
The requirement for TM44 air conditioning inspections originates from the Energy Performance of Buildings (England and Wales) Regulations 2012, which implemented the EU Energy Performance of Buildings Directive into UK law. Despite Brexit, this legislation remains fully in force. The regulations place a clear legal obligation on the person responsible for operating an air conditioning system — typically the building owner, landlord or tenant depending on lease arrangements — to ensure the system is inspected at intervals of no more than five years.
The inspection must be carried out by a qualified energy assessor holding the appropriate level of accreditation. At AirCert, our assessors hold both Elmhurst Level 3 and Level 4 accreditation, meaning we are qualified to inspect air conditioning systems of any size and complexity — from single split units above the 12kW threshold through to large centralised systems in commercial buildings, hospitals and retail centres across the North East and Yorkshire.
Who Is Responsible for Compliance?
Determining who bears legal responsibility for TM44 compliance can cause confusion in leased commercial properties. The regulations place the duty on the “relevant person” — defined as the person who has control of the operation of the air conditioning system. In practice, this typically means:
- Building owners: If the owner retains operational control of the HVAC systems, they are responsible for arranging inspections and avoiding TM44 inspection penalties.
- Landlords: Where the landlord maintains common areas and shared systems, the obligation — and the liability for any penalties — falls on them.
- Tenants: If a lease assigns responsibility for maintaining and operating the air conditioning system to the tenant, the tenant may be the relevant person under the regulations.
- Facilities managers: While FMs often arrange inspections on behalf of building owners, the legal liability for TM44 inspection penalties remains with the responsible person named in the lease or ownership structure.
Regardless of your specific arrangement, someone must ensure the TM44 inspection is completed and a valid certificate is held. Ignorance of the requirement is not a legal defence against TM44 inspection penalties.
What Are the Actual TM44 Inspection Penalties?
TM44 inspection penalties are issued as fixed penalty notices by the local Trading Standards authority (also known as the weights and measures authority). The full penalty structure is more severe than many building managers realise:
- Initial penalty — £300: A fixed charge notice of £300 is issued for failing to hold a valid air conditioning inspection report.
- Weekly repeat fines — £300 per week: This is the detail most building managers overlook. The £300 TM44 inspection penalty can be reissued every week until the building is compliant. A building without a certificate for three months could face £3,600 in repeat fines from a single system alone.
- Failure to produce documentation — £200: If a Trading Standards Officer requests your TM44 certificate and you cannot produce it within seven days, a separate £200 fine applies.
- Maximum cumulative exposure — £5,000+: When weekly repeat fines, documentation penalties and multiple non-compliant systems are combined, total TM44 inspection penalties can comfortably exceed £5,000.
- Per-system penalties: Each air conditioning system without a valid certificate constitutes a separate breach. A portfolio landlord with multiple non-compliant buildings faces the full penalty structure for each one.
How Enforcement of TM44 Penalties Works
Enforcement is carried out by Trading Standards Officers (TSOs), who verify compliance directly via the government’s Landmark database — the national register where all valid TM44 certificates are lodged. This means officers do not need to visit a building to establish non-compliance; they can identify buildings with no current certificate on the register before they set foot on site. The assumption that enforcement is inconsistent and unlikely is becoming increasingly unreliable.
The UK government has been steadily tightening enforcement of energy performance requirements across the board. The introduction of Minimum Energy Efficiency Standards (MEES) for commercial buildings and the strengthening of EPC enforcement have created a broader compliance culture within local authorities. TM44 inspections sit within this same regulatory framework — as enforcement teams become more active on EPCs and MEES checks, TM44 compliance is being picked up as part of the same audits and site visits.

The UK government’s official guidance on energy performance of buildings makes clear that local authorities have both the power and the duty to enforce these regulations. As net-zero targets intensify and the Landmark database makes non-compliant buildings trivially easy to identify, the risk of enforcement is only increasing.
Beyond TM44 Inspection Penalties: The Hidden Costs of Non-Compliance
Focusing only on the financial penalties misses the broader picture. The TM44 inspection exists because poorly maintained or inefficiently operated air conditioning systems waste significant amounts of energy. The inspection report produced by a qualified assessor does not just protect you from TM44 inspection penalties — it provides actionable recommendations that deliver real, measurable savings.
Energy Waste and Increased Operating Costs
Air conditioning typically accounts for 20–35% of a commercial building’s electricity consumption. Systems that have never been independently assessed may be running with refrigerant leaks, blocked filters, incorrect control settings, oversized units or outdated technology — each of which drives up energy bills unnecessarily. A TM44 inspection identifies these problems and provides a prioritised improvement list, many items of which offer rapid payback periods.
Our Elmhurst Level 3 and Level 4 accredited assessors regularly identify energy savings opportunities during TM44 inspections across Middlesbrough, Teesside, County Durham, Newcastle, Sunderland and throughout Yorkshire. In many cases, the savings identified in the first year alone exceed the cost of the inspection several times over — making early compliance the financially rational choice even before TM44 inspection penalties are considered.
Carbon Reporting and Corporate Responsibility
Businesses subject to Streamlined Energy and Carbon Reporting (SECR) or the Energy Savings Opportunity Scheme (ESOS) must demonstrate responsible energy management. Holding valid TM44 certificates and acting on inspection recommendations directly supports these obligations and strengthens your organisation’s environmental credentials with clients, investors and supply-chain partners.
How to Avoid TM44 Inspection Penalties
Avoiding TM44 inspection penalties is straightforward: ensure every air conditioning system with a combined effective rated output above 12kW holds a valid, in-date TM44 certificate. Here is a practical checklist:
- Audit your systems: Identify every air conditioning system across your portfolio. Remember the 12kW threshold applies to the combined rated output — multiple smaller units may collectively exceed it even if no individual unit does.
- Check your existing certificates: TM44 certificates are valid for five years. If yours is approaching expiry, arrange renewal well in advance — a lapsed certificate exposes you to the full TM44 inspection penalty structure from day one.
- Appoint an accredited assessor: The inspection must be carried out by an assessor with the correct level of accreditation. AirCert holds both Elmhurst Level 3 and Level 4 accreditation, ensuring we can inspect any system you operate.
- Act on recommendations: While implementing every recommendation is not legally required, doing so delivers genuine energy savings and demonstrates good practice to auditors and enforcement officers.
- Set a reminder system: Calendar reminders set six months before expiry give you ample time to arrange a new inspection without any gap in compliance — and without risking weekly repeat TM44 inspection penalties.

Frequently Asked Questions About TM44 Penalties
Can I appeal a TM44 penalty notice?
Yes. If you receive a TM44 inspection penalty notice, you have the right to request a review by the issuing authority and, if unsuccessful, to appeal to the county court. However, the simplest approach is to ensure compliance before enforcement action begins — the inspection cost is a fraction of the cumulative weekly fines.
What if my air conditioning system has been decommissioned?
If a system has been permanently decommissioned and is no longer operational, it does not require a TM44 inspection. Retain written evidence of decommissioning — such as an engineer’s report — in case a Trading Standards Officer queries the absence of a certificate on the Landmark database.
Does a TM44 inspection replace routine maintenance?
No. A TM44 inspection is a regulatory energy efficiency assessment — it is not a substitute for regular servicing by an F-Gas registered engineer. Both are legally required for different purposes and both are necessary for optimal system performance and full compliance.
How quickly can AirCert carry out an inspection?
We typically arrange inspections within one to two weeks of enquiry, though urgent requests — including those prompted by a penalty notice — can often be accommodated more quickly. Contact us for a quote and we will confirm availability for your location and system type.
