TM44 Inspections Across Greater London
Under the Energy Performance of Buildings (England and Wales) Regulations 2012, all air conditioning systems with an effective rated output exceeding 12kW must be regularly inspected by an accredited energy assessor and the report lodged to the Landmark Domestic & Non-Domestic Register. London commercial landlords, tenants, and public bodies who fail to comply face civil fines of up to £5,000 per premises.
Avorria's London-based TM44 assessors hold accreditations under the CIBSE Low Carbon Consultant programme and the wider Non-Domestic Energy Assessor (NDEA) framework. Operating from our Canary Wharf office (37th Floor, 1 Canada Square), we efficiently mobilise across all London zones to inspect systems from simple split-type units to complex multi-zone variable refrigerant flow (VRF) networks and district chiller plant.

What Does a TM44 Report Cover?
- System Inventory: Full documentation of all AC plant, outdoor condensers, indoor units, and auxiliary equipment including refrigerant type and circuit configuration.
- Controls Assessment: Evaluation of BMS, thermostatic controls, scheduling, and zoning to identify oversizing or inefficient operation patterns.
- Maintenance Record Review: Analysis of F-Gas log books, service history, and refrigerant top-up frequency to flag ongoing inefficiency or leakage.
- Energy Reduction Recommendations: Ranked recommendations for controls upgrades, refrigerant retrofits, or partial/full system replacement with indicative payback periods.
- Formal Lodgement: Inspection report submitted to the Landmark database. Certificate reference number provided for lease compliance and due diligence purposes.

London TM44 Client Reviews
Rated 4.9/5 from 89 verified London TM44 inspections
"Quick, thorough TM44 inspection for our 4-floor office in the City. The assessor understood our Daikin VRF system fully and provided a clear improvement report. Certificate on Landmark the same day."
Caroline HughesHead of Facilities, EC2 Corporate Office"Avorria handled TM44 for three of our Canary Wharf properties simultaneously. Their logistical efficiency is excellent — minimal disruption to tenants, all certificates delivered in one batch."
Alex DrummondAsset Manager, E14 Portfolio"We had a complex split-system and central chiller installation at our Westminster venue. The assessor was knowledgeable, patient, and the report exceeded what we expected."
Sarah FinchOperations Director, SW1 Events VenueLondon TM44 — Frequently Asked Questions
Who is responsible for arranging the TM44 inspection?
Responsibility typically falls on the commercial landlord or building owner. In multi-tenant buildings, the building manager or facilities team usually coordinates. For tenanted properties, lease terms should specify who bears TM44 costs — often the tenant under a full repairing lease.
What happens if my TM44 has expired?
Expired or missing TM44 certificates leave landlords and building owners exposed to enforcement action by Trading Standards. Civil penalties of up to £5,000 per building apply. We can arrange urgent inspections to restore compliance quickly.
How long is a TM44 certificate valid?
TM44 inspection reports are valid for 5 years from the date of inspection. Avorria offers calendar reminder services to notify you 3 months before renewal is due, helping avoid missed compliance dates.
Does TM44 apply to server rooms and data centres?
Yes — precision cooling systems (CRAC units) and close-control air conditioning in data centres and server rooms are subject to TM44 if the effective rated output exceeds 12kW. These require specialised assessors with knowledge of data centre thermal management.
Can I book TM44 + Commercial EPC together?
Absolutely. We offer combined booking for Commercial EPC + TM44 inspections, often on the same site visit, saving on assessor mobilisation costs. This is the most efficient approach for London properties requiring both.
What is the difference between TM44 and F-Gas?
TM44 is an energy efficiency inspection required by the EPBD. F-Gas regulations separately require that refrigerant-containing systems are regularly checked for leaks by an F-Gas certified engineer. Both are legal obligations — Avorria provides TM44 while your engineering contractor handles F-Gas logs.
