This guide applies whoever you call, including us. The aim is not to find a reason to pick one firm; it is to make sure you are comparing the same thing, so the price you accept is for the job you need.
Which Treatment Are They Offering?
Start here, because it shapes everything else. Heat treatment raises the room to a temperature bedbugs cannot survive, holds it, and uses a thermal camera to check for cold spots; it kills eggs and is usually one visit. Chemical treatment leaves a residual insecticide in seams, frames and skirtings; it does not reliably kill eggs, so it is usually two or three visits. Heat costs more. Neither is wrong, but a quote that does not say which one you are getting is not a quote yet.
Our London guide comparing heat and chemical treatment sets the two side by side if you want to decide before you ring anyone.
Questions to Ask on the Phone
- Which rooms will you treat, and why those rooms?
- Is the price for one visit or for the whole course, and how many visits is that?
- How far apart are the visits, and how long does each one take?
- What do I need to do before each visit, and will you send that as a list?
- What happens if we still see signs after the last visit?
- What will you tell me to do, and not do, between visits and afterwards?
A firm that knows its work can answer each of these plainly. Vague answers to the visit questions in particular usually mean the price covers less than it seems.
How the Price Should Be Set

A bedbug price depends mainly on how many rooms are treated and which method is used. Anyone quoting you should ask about both before giving a figure: how many bedrooms, which have signs, whether a sofa or living room is involved, and whether it is a house or a flat. A single figure given before any of that is a guess.
For comparison, our treatments start from £220 and inspections from £120, and the final figure depends on the room count and on heat or chemical. We give it on the phone before anything is booked. Whatever you are quoted, check it is the whole course rather than the first visit.
What You Should Get in Writing
- The rooms being treated and the method.
- The number of visits included and the planned gap between them.
- The price, and what it covers.
- Your preparation list for each visit, or for the heat day.
- What to do afterwards, and who to ring if you see anything.
If you rent, keep that paperwork. Your landlord or agent may ask for it, and who arranges and pays depends on the tenancy and the cause. We are pest controllers, not legal advisers, but we can talk to whoever is arranging the work. Landlords with several rooms can see the Hounslow commercial page.
Warning Signs in a Quote
- No question about how many rooms, or which ones, before the price.
- A single chemical visit offered as the whole job, with nothing said about eggs.
- Advice to throw out the mattress or bed before anyone has looked.
- Pressure to book today, or a price that only holds if you agree on the call.
- Promises that sound absolute. Honest firms tell you what each method does not do.
Should You Get an Inspection First?
If you have found a bug or clear spotting, you can usually go straight to a treatment quote. If you have only bites, or you do not know which rooms are involved, an inspection means the treatment is priced on what is actually there. The Hounslow inspections page covers that, and the Hounslow page explains how we fit either treatment around a household.
Related Questions
Is the lowest quote a bad sign?
Not on its own. Check it covers the same rooms, the same method and the same number of visits as the others before comparing figures.
Why do some firms quote more for heat?
Heat needs more equipment and a longer time on site, so it costs more than chemical. In return it is usually one visit and kills eggs as well.
Should I use a firm that sells me a spray to use myself?
Shop and home sprays tend to scatter bedbugs rather than deal with them. Treatment in the seams, frames and skirtings, or heat, is what does the job.
Do I have to be home for the visits?
Someone needs to let us in and hear the instructions. For heat, the rooms and pets are out for most of the day; for chemical, you can use the room once it is dry.
