Bed Bug Heat Treatment Costs in London: What to Expect
Bed bugs are a growing issue across London’s dense housing, busy transport network and thriving hospitality sector. Understandably, the first question we’re asked is: how much will it cost to get rid of them? Below, we give realistic London price ranges, explain what drives cost, and show why whole‑room heat is the most reliable and cost‑effective route to eradication in a single day. As the UK’s heat specialists, ThermoPest delivers specialist bed bug heat treatment in London for flats, houses and commercial premises.
What does bed bug removal really cost in London?
Every quote is property‑specific, but these ballparks help set expectations in the capital:
- Studio or 1‑bed flat: typically £700–£1,100 for whole‑room heat treatment.
- 2‑bed flat or small terraced house: typically £900–£1,400.
- 3–4 bed home: typically £1,200–£1,800, depending on size and clutter.
- Hotels/hostels (block treatment): often £250–£400 per affected room when treated in batches (economies of scale apply).
- Follow‑up confirmation/monitoring: commonly £80–£200, depending on devices and revisit requirement.
What pushes cost up or down in London? Property size and layout (split‑levels, thick walls), clutter and storage, the extent and age of the infestation, access/parking and lift availability, and whether treatment must be out‑of‑hours (e.g., hotels, short‑lets). Chemical spray programmes may look cheaper per visit (£180–£350), but they usually require multiple visits and still struggle with eggs and hidden harbourages—so the total and timescale often end up higher than a single‑day heat treatment.
What people believe vs reality
- Belief: “One spray will sort it.” Reality: Eggs are resilient and many strains show reduced susceptibility; sprays need repeat visits and perfect coverage to work.
- Belief: “I’ll throw the bed out.” Reality: You may spread bugs through shared corridors or stairwells and still leave harbourages in skirtings, frames and sockets.
- Belief: “A fogger will flush them.” Reality: Aerosol foggers rarely deliver lethal doses to hiding places and can push bugs deeper into the structure, creating costly delays.
- Belief: “They came from a dirty place.” Reality: Bed bugs track people, not hygiene. In London they move via travel, the Tube, house‑shares and multi‑unit buildings.
Science‑backed facts that influence cost
- Bed bugs and eggs die when every part of them reaches and holds lethal heat. See what temperature kills bed bugs for the science behind 50–60°C targets.
- Eggs are the toughest stage; any method that leaves cold pockets risks survival and a rebound—triggering more visits and more cost.
- In London’s varied building stock (Victorian voids, concrete high‑rises), heat distribution must be engineered carefully to avoid cold spots.
Common mistakes that make London jobs more expensive
- Moving clothing or furniture through communal hallways and on public transport, spreading bugs to new locations.
- Using shop foggers or casual DIY sprays that scatter infestations into wall voids and neighbouring flats.
- Partial treatments (one room only) in connected dwellings; bugs simply migrate.
- Poor preparation—overfilled cupboards and under‑bed storage slow heat penetration and can require longer visits.
- Waiting too long; established infestations take more energy, time and monitoring to confirm clearance.
Practical steps you can do safely to keep costs down
- Follow guidance on preparing your home for treatment—declutter sensibly, bag and stage items, and ensure airflow around beds and furniture.
- Launder washable textiles at 60°C and dry on high heat; store cleaned items sealed until after treatment.
- Do not move untreated items through communal areas; keep everything contained in the affected rooms.
- Vacuum slowly with a crevice tool around bed frames and skirtings; dispose of contents sealed.
- After the visit, monitor your property after treatment so any reintroduction is caught early and cheaply.
Why heat treatment is the superior solution
- Cold spots: Professional heat systems actively circulate air and check known cool zones (external walls, under carpets, inside drawers) to prevent survival pockets.
- Sustained lethal temperature: We raise contents to 50–60°C and hold it long enough for full mortality across rooms and belongings, not just surfaces.
- Sensors and monitoring: Multiple wireless probes verify temperatures inside mattresses, furniture joints and voids, and guide technicians to adjust airflow in real time.
- All life stages killed: Adults, nymphs and eggs are eliminated in one planned visit—reducing repeat call‑outs and disruption.

ThermoPest expertise in London
We carry out domestic heat treatments across London’s flats, terraced homes and HMOs, and coordinate discreet access in buildings with limited parking and lifts. For commercial clients, we plan block treatments and off‑peak scheduling to limit room‑night loss. If you need a costed plan that fits your building and timetable, ThermoPest’s London team will survey, price transparently and engineer a one‑day solution with clear aftercare.
FAQ’S
Question: How much does professional bed bug heat treatment cost in London?
Answer: Typical whole‑room heat treatment ranges from about £700–£1,100 for a 1‑bed flat, £900–£1,400 for a 2‑bed, and £1,200–£1,800 for larger homes. Commercial sites treated in blocks often achieve £250–£400 per affected room. Prices vary with size, clutter, access, infestation age and scheduling. A quick way to refine your quote is to share a simple floor plan and photos— in professional practice, that speeds accurate planning.
Question: Why is heat treatment more expensive than spraying?
Answer: Heat requires specialised equipment, trained technicians and energy to achieve and hold lethal temperatures, which raises the headline price. However, it kills eggs and avoids cold spots through constant sensor monitoring, so it’s usually a one‑day solution versus multiple chemical revisits. When you compare total cost, time off work, disruption and the risk of repeat sprays, heat commonly works out cheaper overall. In professional practice we factor both efficacy and total cost of control, not just per‑visit fees.
Question: Will heat treatment damage my furniture or electronics?
Answer: Most household items tolerate bed bug heat levels (typically 50–60°C) without issue; technicians shield or remove known heat‑sensitive items and manage airflow to protect finishes. Adhesives can soften and some plastics may warp if already stressed, which is why pre‑treatment checks and selective protection matter. Your team will advise what to unplug and what to set aside safely. In professional practice, careful preparation and temperature monitoring prevent heat‑related damage.
Question: Do I need follow‑up visits after heat treatment?
Answer: Most heat treatments are designed to be single‑visit, with monitoring to confirm success as rooms cool. Any later activity is typically reintroduction (e.g., luggage or shared seating) rather than a true reinfestation from surviving eggs. We recommend visual checks and passive detectors for 2–4 weeks to verify no signs return. In professional practice, we sign off clearance with monitoring rather than routine repeat heats.
Question: How can I keep costs down before and after treatment?
Answer: Prepare properly: declutter sensibly, bag textiles, launder at 60°C, and create airflow under and around beds so heat reaches every surface. Don’t use foggers or move items through communal areas, as this spreads bugs and increases job time. After treatment, use interceptors or monitors and minimise high‑risk exposures (second‑hand furniture, untreated luggage). In professional practice, good preparation and monitoring consistently reduce total cost.
