Fast Certificate Turnaround

Missing a TM44 inspection deadline can leave your business exposed to legal risk.

Any commercial building with an air conditioning system over 12kW must have a valid TM44 inspection certificate by law. Getting caught without one — or with a certificate issued by an unaccredited inspector — is a risk no building manager, landlord or facilities team should take.

We help building managers, facilities managers, landlords and business owners get clear, legally-compliant TM44 certificates from an Elmhurst-accredited inspector they can trust.

  • No missed deadlines
  • No vague or non-compliant reports

Just straightforward TM44 certification from a fully accredited, experienced inspector you can rely on.

Why Compliance Matters

TM44 inspections aren’t just a legal requirement — they’re an opportunity to identify inefficiencies, reduce energy costs, and protect your business from enforcement action. Here’s what clients typically gain from an AirCert inspection:

  • Outdated A/C electrical panel identified by AirCert→ Prevented fire hazard
  • TM44 missing during building sale → inspection completed in 48 hours, transaction saved
  • Certificate expiring unnoticed → renewal booked in time, zero compliance gap
  • Non-Compliant A/C System Flagged by AirCert. Client avoided enforcement action

A TM44 inspection is a statutory assessment of air conditioning systems required under the Energy Performance of Buildings Regulations 2012. It applies to any fixed AC system with an effective rated output greater than 12kW. During the inspection, an Elmhurst-accredited assessor evaluates the efficiency of the system, checks for faults or areas of concern, and produces a detailed report with practical recommendations. Once complete, a TM44 certificate is issued and lodged on the national register, confirming your building is legally compliant

Any organisation responsible for a building containing a fixed air conditioning system with an effective rated output of more than 12kW is legally required to hold a valid TM44 certificate. This includes offices, retail units, restaurants, hotels, schools, hospitals, care homes, gyms, leisure centres and many other commercial and public sector premises. The legal responsibility typically falls on the building owner, though it can be passed to the occupying tenant depending on the terms of the lease. If you are unsure whether your building is affected, AirCert can advise you.

TM44 inspections are required every five years. Once your certificate has been issued, you have five years before your next inspection is due. It is important to keep track of your certificate expiry date — allowing it to lapse puts your business at risk of financial penalties and can cause complications during property sales, lease renewals or building audits. AirCert can advise you on your current compliance status and book your next inspection well ahead of any deadline.

An AirCert inspection begins with a review of your AC system documentation, followed by a thorough on-site assessment of all qualifying equipment. Our Elmhurst-accredited assessor will check the condition and efficiency of the system, review controls and maintenance records, and assess whether the system is appropriately sized for the building. The visit is carried out with minimal disruption to your business. Following the inspection, you will receive a detailed TM44 report outlining any recommendations, and your certificate will be issued promptly and lodged on the national register.

TM44 inspection costs vary depending on the size and complexity of your AC installation — a single system in a small office will cost significantly less than a multi-system installation across a large commercial building. AirCert offers competitive, transparent pricing with no hidden charges. We will always provide a clear, fixed quote before any work is carried out so you know exactly what to expect. Get in touch for a free no-obligation quote tailored to your specific requirements.
