Bed bug treatment in London typically costs £175 to £450 for chemical spray treatment, usually spread over two to three visits, or £350 upwards for heat treatment, which can clear a whole room in a single visit. The right choice, and the final price, depends on how many rooms are affected, how bad the infestation is, and which method a specialist recommends. A specialist will give you a firm quote once they know the size of the job; the ranges below are a guide to help you compare what you're offered.
How much does pest control cost in London?
Pest control prices in London vary by pest and job size, and bed bugs sit at the pricier end because of the number of visits or the specialist equipment involved. Based on published prices from London pest control businesses, chemical spray treatment for bed bugs typically runs £175 to £250 a visit.
Most infestations need two to three visits around two weeks apart, so the full job often lands between £350 and £750. Heat treatment is usually quoted per room, from around £350 for one room up to £1,500 or more for a whole property.

How much should I pay for bed bug treatment?
What you pay depends on the method, how many rooms are affected, and how bad the infestation is. A single lightly affected room with chemical treatment sits at the lower end of the range; a whole flat with an established infestation, or one needing heat treatment throughout, costs more. Get more than one quote where you can, and check what's included, the number of visits, any follow-up, and what preparation you need to do beforehand.
Why is bed bug removal so expensive?
Bed bug treatment costs more than many other pest jobs because it's rarely a single visit: chemical treatment typically needs two to three repeat visits about two weeks apart to catch newly hatched bed bugs, and heat treatment needs specialist equipment, monitoring and enough time on site to heat an entire room properly, not just spray a surface.
Missing a hiding spot means the infestation can come back, so thoroughness costs more than a quick spray. Bed bugs hiding in furniture and soft furnishings cost more to treat than many insects that stay out in the open, and spotting the early signs before the infestation spreads to other rooms keeps the job, and the price, smaller.
Questions people ask
Does the price include more than one visit?
For chemical treatment, usually yes, most quotes are built around two to three visits since a single spray rarely catches bed bugs that hatch afterwards. Heat treatment is more often a single visit. Check exactly what's included before you book, since this is the main reason quotes vary.
Is heat treatment more expensive than chemical spray?
Generally yes, upfront. A single room of heat treatment often costs more than one chemical visit, but because heat treatment can clear a room in one go rather than needing repeat visits, the total cost for a full job can end up closer between the two methods.
Will the price change once a specialist sees the job?
It can. The ranges here are a guide; the real price depends on how many rooms are affected and how established the infestation is, which a specialist can usually only judge properly in person or from clear photos. That's why getting an actual quote matters more than going on a published range alone.
