The service
A single specialism, carried out and recorded the same way every time
Bed bug heat treatment is what we do — it is not an add-on to a general pest control round. The method does not change by borough or postcode: what changes is the property, the access and the preparation, and those are assessed for your address.
Whole-room heat, not surface spraying
The treated space and its contents are brought up to treatment conditions together, reaching seams, joints, frames and voids.
Monitored against an approved 56°C target
The target applies to the treatment as a monitored whole. A single reading at one position does not, on its own, demonstrate what happened across the treatment environment, which is why multiple positions are monitored and recorded during treatment.
A written record afterwards
A Service Record of what was treated and what was measured, available to you in the customer portal.
How the treatment works
Heat applied to the whole treated area, not just the surfaces you can see
Bed bugs live in the places a spray cannot reliably reach — mattress seams, bed frame joints, headboard fixings, skirting gaps and furniture voids. Heat treatment works on the treated space as a whole rather than on the surfaces that can be sprayed.
The treated space is heated as one
Professional heating equipment raises the temperature of the room or property under controlled conditions, so the air, the furniture and the contents come up together.
Distribution is the hard part
A hot room is not the same as an evenly treated room. Airflow is managed and cooler positions are worked on deliberately, because harbourage sits in the places heat reaches last.
Belongings are treated in place where suitable
Most soft furnishings, bedding and furniture are treated where they are. Heat-sensitive items are removed first — that is what preparation is for.
Verification is the reason the method is worth doing properly: without measurement there is no way to know that treatment conditions were reached where they needed to be. The full technical explanation is on the Bed Bug Heat Treatment and How Heat Treatment Works pages.
If you have already had treatment
Heat treatment and chemical treatment are different approaches
Many people reach this page after a chemical treatment programme has already been started. That does not mean the earlier work was wrong.
Chemical treatment has a legitimate place
Applied by a competent professional, chemical treatment can be an appropriate control method in some circumstances. We are not going to tell you it does not work.
Programmes often need several visits
Repeated treatment programmes are commonly structured across multiple visits over a period of weeks, with preparation and access required each time.
Outcomes depend on many factors
Property type, level of activity, harbourage, preparation, access and neighbouring properties all affect the result of any treatment method.
We specialise in monitored heat
We provide one method and we measure it. If you specifically searched for heat treatment, that is the approach this service is built around.
Not sure what you are dealing with yet? Could This Be Bed Bugs? walks through the evidence before anyone talks about treatment.
Temperature monitoring
Measured during treatment, not estimated afterwards
Temperature is the whole basis of the method, so it is monitored while the work is carried out, at positions chosen for the property and the treatment area.
Operational treatment target
56°C
The target applies to the treatment as a monitored whole. A single reading at one position does not, on its own, demonstrate what happened across the treatment environment, which is why multiple positions are monitored and recorded during treatment.
Monitoring positions
Selected for the property, the treatment area and the technician's assessment. We do not publish a fixed number, because the right number and placement depend on the property.
Treatment duration and hold periods
Confirmed for your treatment by your technician rather than quoted online as a universal figure. Recorded treatment information forms part of your treatment record.
Multiple positions matter because a single reading only describes one point in the room. Verification is part of the documented process, not an optional extra. How heat treatment works.
Treatment day
What happens at the property
The same sequence applies wherever you are in Greater London. Timings depend on the property, the number of rooms and the access arrangements.
- 01
Arrival and checks
The technician confirms the treatment areas, checks preparation and identifies anything that still needs to be removed or protected.
- 02
Equipment setup
Heating and air-movement equipment is positioned for the property, and monitoring positions are placed before heating begins.
- 03
Heat and monitoring
The treated area is brought up to treatment conditions and monitored throughout, with adjustments made to reach cooler positions.
- 04
Verification
Measured conditions are recorded so the treatment can be evidenced rather than described.
- 05
Completion and aftercare
The property is made safe, re-entry is confirmed by the technician, and aftercare guidance is given before the team leaves.
- MORE
The full day, step by step
Arrival windows, access, pets, re-entry and what to expect afterwards are set out in the guidance issued to customers in the customer portal.
Preparation
You are told what to do before treatment day
Preparation is the single biggest factor you control. You receive written guidance in advance, and your technician confirms anything specific to your property.
Preparation
Written preparation requirements for your property are issued with your treatment and held in your customer portal.
Items to remove
Heat-sensitive items that must be taken out of the treated area are confirmed for your property before treatment day.
Documented service
What you are left with afterwards
A treatment you cannot evidence is a treatment you have to take on trust. Ours is written down.
Monitored treatment
Conditions are measured during the work at positions selected for your property.
Sample Service Record

Access and logistics
Planning a treatment in South West London
The method does not change from one part of London to another. What changes is how equipment reaches the property, who has to give permission, and how many occupied rooms need preparing. These are the questions we settle before a date is held.
Riverside and inner boroughs have controlled parking zones and narrow residential streets, so loading position is agreed in advance.
Converted Victorian houses mean shared entrances and party walls between units, which affect sealing and monitoring.
Suburban family housing further out usually allows driveway loading and predictable internal layouts.
Why we publish zone pages, not a page for every postcode
Every borough, named local area and postcode district in Greater London is held in the CoverageMaps Pro™ registry and is searchable, but a separate page per postcode would repeat the same service with a different heading. Instead, eight zone pages carry the service detail and the registry carries the geography, so what you read here is the same answer you would get for any address in South West London.
