TM44 Warning Letter: What Building Operators Should Do

A TM44 warning letter calls for prompt fact-finding: verify who sent it, identify the premises and deadline, and locate the relevant inspection report. Treat the communication seriously without guessing either that it is fraudulent or that every allegation is correct.

A warning, a request for information and a penalty notice can have different consequences. Follow the actual document and obtain legal or accredited-assessor support where its requirements or underlying facts are uncertain.

The essentials

What you need to know

  • Verify the sender independently and preserve the original letter.
  • Identify the response date and appoint an owner for the reply.
  • Check the report, system scope and responsible party.
  • Keep evidence of correspondence and any inspection arrangements.
01 / 06

Verify sender and reference details

Use the authority’s published website or switchboard to verify the contact, case reference and address. Keep the envelope or original electronic message, including the date received.

Do not use an unverified payment link or share building access information with an unknown sender. If the communication is genuine, ask for clarification through the confirmed channel where the request is unclear.

02 / 06

Check applicable law and cooling-system eligibility

Establish whether the building is in England, Wales, Scotland or Northern Ireland before applying a rule. For England and Wales, gather effective rated cooling output and the facts about grouping and technical control.

If you believe the system falls outside scope, support that position with reliable equipment information. A small occupied floor area or an empty tenancy is not, by itself, a demonstrated exemption.

03 / 06

Find the last accredited report and scope

Search the property records for the complete last report and applicable reference. Ask the previous operator, assessor or managing agent where necessary and compare the document with the installed plant.

Keep a record of searches and requests. An unsuccessful postcode lookup may mean the document has not been located; it does not, on its own, establish the installation’s full inspection history.

04 / 06

Document facts instead of admitting an assumed breach

Prepare a short chronology of the inspection, equipment changes and any transfer of control. Distinguish confirmed facts from questions still being checked.

Correct a factual mistake clearly, with supporting records, rather than making a blanket statement about compliance. For disputed liability or a formal notice, obtain advice tailored to that communication.

05 / 06

Meet stated response deadlines and obtain professional advice

Put the stated deadline in the responsible person’s diary and retain evidence of the response. If essential information is outstanding, explain this promptly to the authority and request clarification or time where appropriate.

Do not assume that contacting an assessor or booking a visit automatically stops enforcement. Any extension or agreed next step should be confirmed by the authority and retained with the case file.

06 / 06

Arrange any required inspection and retain evidence

Where an assessment is required, give the provider the actual plant details, access arrangements and deadline. Ask what assessor attendance and report issue can realistically be confirmed.

Retain the booking confirmation, subsequent report and correspondence. Supply the evidence requested through the confirmed channel, while recognising that an inspection does not itself determine the outcome of any separate proceedings.

Check the governing guidance

This article does not authenticate a government register entry or establish the status of an individual building. Confirm the applicable national framework and the actual installed equipment before relying on a compliance conclusion.

England and Wales legal points are anchored in current government publications and the regulations. Technical applicability for a specific building still requires its actual system information.
