Let’s be upfront about something: heat treatment costs more than a chemical spray. There’s no getting around that. But when you look at what you’re actually getting for the money — and what you’re likely to spend if you go the cheaper route — the picture looks quite different.
This article explains what heat treatment costs in the UK, what affects the price, and why for most people dealing with a real infestation, it works out to be the better investment.
What Does Bed Bug Heat Treatment Cost in the UK?
Prices vary depending on the size of your property and the extent of the infestation, but as a general guide:
- A one-bedroom property typically costs between £400 and £700
- A two to three bedroom house usually falls between £750 and £1,200
- Larger properties will cost more, with prices rising in line with the number of rooms being treated
These figures are for a full professional heat treatment — industrial equipment, temperature monitoring throughout, and a single visit that deals with the problem in one go. Some companies charge per room, others price by property size, so it’s always worth getting a clear, itemised quote before you commit.
What Affects the Price?
A few things will push the cost up or bring it down.
The size of your home. More rooms mean more equipment, more time, and more work. A studio flat is a straightforward job. A large detached house with an infestation spread across multiple rooms is considerably more involved.
How far the infestation has spread. A contained infestation in one bedroom is easier and quicker to deal with than one that’s worked its way through several rooms. The further it’s gone, the more thorough the treatment needs to be — and that’s reflected in the price.
Where you live. Prices in London and the South East tend to be higher than elsewhere in the UK, partly due to higher operating costs and partly due to demand. In Surrey, prices are generally in line with the wider South East market.
The company you choose. Not all pest control companies offer heat treatment, and among those that do, standards vary. A fully qualified team with the right equipment and proper guarantees will cost more than a cheaper option — but with something like this, that difference in quality really matters.
How Does It Compare to Chemical Treatment?
A chemical spray treatment is cheaper upfront — typically around £280 for a standard treatment — which makes it an appealing first step when you’re already stressed about an infestation.
The problem is that chemical treatments rarely work first time. To fully eradicate bed bugs using sprays, two visits about two and a half weeks apart are generally recommended, and even then the eggs can take up to a month to hatch — by which time the residual effect of the spray has worn off. A third visit is not uncommon.
Add those visits together and the cost quickly climbs. And that’s before you factor in the ongoing disruption, the stress of a problem that keeps coming back, and the very real possibility that the bugs have spread further in the meantime.
Heat treatment deals with the infestation in a single visit — adults, nymphs, and eggs, all in one go. You pay once, the problem is resolved, and you don’t need to book anyone back in.
Why Does Heat Treatment Cost More?
It’s worth understanding what goes into the price, because it explains why the cost is what it is.
A professional heat treatment requires industrial heating equipment and high-powered fans, which are expensive to buy and maintain. It takes a team — not a single person with a spray — and they’re on site for the better part of a day, monitoring temperatures throughout the property to make sure every part of the space reaches and holds the right temperature. That level of care and equipment doesn’t come cheap, and it shouldn’t.
What you’re paying for is a treatment that works the first time. A single visit, no repeat bookings, no weeks of uncertainty, and no risk of waking up the following month to find the problem has come back.
What About DIY Options?
Supermarket sprays, fogging machines, and other off-the-shelf products are significantly cheaper than professional treatment. But they’re also significantly less effective.
Bed bugs have developed resistance to many of the chemicals available in DIY products, and even professional-strength sprays struggle to reach the places bed bugs actually hide. DIY treatments often do little more than push the infestation deeper into furniture and walls, making it harder — and more expensive — to deal with properly later on.
If anything, trying to treat bed bugs yourself before calling a professional tends to make the professional’s job more difficult, and can add to the overall cost of resolving the problem.
Is It Worth It?
For most people dealing with a confirmed bed bug infestation, yes — clearly.
Think about what an untreated or poorly treated infestation actually costs you. Weeks of broken sleep. The stress of not knowing whether it’s getting better or worse. Potentially replacing a mattress, bedding, and other items. Repeat visits from a pest controller who’s not getting on top of it. The risk of it spreading to other rooms, or — if you live in a flat — to your neighbours.
Heat treatment removes all of that in a single day. You leave in the morning and come back to a home that’s clear. No chemicals, no residue, no follow-up visits, and no lingering doubt about whether it’s actually worked.
When you look at it that way, the cost isn’t just justified — it’s often the more economical choice in the long run.
How to Get an Accurate Quote
The best way to get a clear, honest price is to get in touch and describe the situation — the size of your property, which rooms are affected, and how long you’ve been aware of the problem. From there, a good pest controller will be able to give you a firm quote rather than a vague estimate.
Be wary of quotes that seem unusually low. Heat treatment done properly requires the right equipment and enough time to do the job thoroughly. A price that seems too good to be true usually means something is being cut — and with bed bugs, that’s a gamble not worth taking.
