- Why Two Quotes Can Look So Different
People are often wary of ringing about price, expecting to be talked into something. The figure is given on the phone before anything is booked, and it comes from a short list of factors. Knowing them helps you ask the right questions, of us or anyone else.
The Number of Rooms
This is the biggest single factor. A problem confined to one bedroom is a smaller job than one that has reached the living room, the sofa and a second bedroom. Each room adds preparation, equipment and time.
That is why the room count is the first thing we ask. It is also why acting early saves money: bedbugs left for a few weeks tend to move into the next room, and the next quote is higher. If you are unsure how far they have got, an inspection from £120 tells you before you pay to treat rooms that might be clear.
Heat or Chemical
Heat costs more than chemical. It needs specialist heaters, fans and a thermal camera, and it takes most of a day on site. In return it kills eggs as well and is usually finished in one visit.
Chemical treatment costs less. Visits are one to two hours, but because the insecticide does not reliably kill eggs, it is usually two visits and sometimes three, around 10 to 14 days apart. The London guide on heat compared with chemical treatment sets the two side by side.

Visits and What the Quote Covers
When you compare quotes, check what each one includes. A low chemical figure for a single visit is not the same job as a course of visits. Ask how many visits are expected, whether the follow-up is included, and what happens if bugs are seen after the course is finished. Ask us the same questions when you ring; that is what they are for. Our London guide on how many treatments it takes explains why one chemical visit is rarely enough.
Preparation and the Cost of a Repeat
Preparation does not change the quote, but it can decide whether the job works first time. Bedding left unwashed, floors covered in clutter, or heat-sensitive items left in the room all make it harder to reach every hiding place. A treatment that has to be repeated costs more in the end, in money and time.
- For chemical: strip and hot-wash bedding, bag it, clear the floor and leave the furniture where it is.
- For heat: take out aerosols, candles, medication, vinyl, plants and some electronics, and get pets out of the flat.
- For both: do not throw out the mattress or bed first unless we advise it.
Costs That Are Not on the Quote
There are costs of your own to plan for. Time off work is the main one, and our guide on how much time off you need breaks that down by stage. Laundry is another: several hot washes and dryer loads, possibly at a launderette. Some people also buy mattress encasements afterwards. None of that is a fee from us, but it is part of the real cost.
Why Two Quotes Can Look So Different
Quotes differ because the jobs being quoted differ. One firm may price a single spray visit, another a full course; one may assume one room, another the whole flat. Ask each for the number of rooms, the method, the number of visits and what preparation you are expected to do, and compare like with like.
Who pays is a separate matter. In rented homes it depends on the tenancy and the cause, and we are pest controllers, not legal advisers. The Tower Hamlets page covers how to raise it with a landlord or housing provider.
Related Questions
What is the lowest-cost way to deal with bedbugs?
Chemical treatment costs less than heat and suits a single contained room. Acting early keeps the room count down, which does more for the price than anything else.
Can you give me a price without visiting?
Yes, we give you a figure on the phone based on the number of rooms and the method, before anything is booked. If nobody is sure how far it has spread, an inspection from £120 comes first.
Is heat treatment worth the extra?
It can be when several rooms are involved, when eggs are a concern, or when finding time for repeat visits is hard. For one contained room, chemical often does the job.
Do you charge for the phone call?
No. 0800 955 1018 is free to call, and the quote is given before anything is booked.
