In Detail

What a TM44 Inspection Covers

Our qualified assessors inspect the full air conditioning installation — including indoor and outdoor units, controls, pipework, refrigerant condition, maintenance records and system documentation. We assess the system against current efficiency benchmarks and identify any remedial actions or improvement opportunities, producing a fully compliant TM44 report on completion.

Legal Compliance

TM44 inspections are a legal requirement under the Energy Performance of Buildings (England and Wales) Regulations 2012. Failure to have a valid inspection report in place can result in penalty notices from local authorities. Our reports are lodged on the national register and provide the documentation required to demonstrate compliance.

Energy Efficiency Advice

Beyond the compliance requirement, our TM44 reports provide practical, actionable recommendations for improving system efficiency and reducing energy consumption. Where systems are ageing or oversized, we can advise on replacement options and provide quotations for upgrade works through our AC installation team.
