Begin with the reason heat is being considered
Explain what evidence prompted the enquiry and whether bed bugs have been identified. If another pest is suspected, make that clear. A method suggested by a forum story or a previous conversation is an option to discuss, not a diagnosis. The team needs to understand the current problem before assessing the relevance of specialist heat.
For Harrow enquiries, give the actual property context and any earlier treatment record. Avoid assuming that the district changes method suitability. The bed bug heat service explains a specialist route, while the wider bed bug treatment information supports discussion of alternatives and assessment.
