How Much Does Bed Bug Treatment Cost in London? 2026 Price Guide

Bed bug treatment pricing varies more than almost any other pest service, mainly because the right method — heat or chemical — depends on your specific situation. Here’s a real breakdown of what to expect.

Inspection / Assessment

Typical cost: £60–£100

Often credited back if you proceed with treatment. Confirms the infestation, assesses severity, and determines which treatment method makes sense for your property.

Chemical Treatment

Typical cost: £250–£400 for a one-bedroom property

Covers two to three visits spaced roughly one to two weeks apart, treating mattresses, furniture, and cracks/crevices with residual insecticide. Costs rise with property size and the number of affected rooms.

Heat Treatment

Typical cost: from £400+ for the first room

A single-session option using specialist equipment to kill bed bugs at every life stage — eggs, nymphs, adults — without chemical residue. Costs more per room than chemical treatment but resolves faster, often in one visit.

Full Property, Moderate Infestation

Typical range: £750–£1,000 total

This is a realistic full-cost picture once all visits are included for a moderately affected one to two-bedroom property, rather than just the headline per-visit price.

What Actually Changes Your Price

  • Property size and number of affected rooms — the biggest single factor
  • Method chosen — heat costs more upfront but often needs fewer visits than chemical treatment
  • Severity — an infestation caught early is cheaper to resolve than one that’s spread through multiple rooms or pieces of furniture
  • Access — HMOs and shared buildings sometimes need coordinated treatment across units, which affects overall cost

Why Bed Bug Pricing Isn’t a Flat Rate

Unlike a wasp nest or a single ant trail, bed bug severity varies enormously between two seemingly similar call-outs — one bedroom with early-stage activity versus a flat with bed bugs established in furniture across multiple rooms are very different jobs. This is why we always confirm final pricing after inspection rather than quoting blind over the phone.

Extermination Process

The Extermination process includes a thorough inspection of your property, sealing off entry points to stop future infestations, using safe and effective pesticides and rodenticides, and providing a warranty.

Frequently asked questions

For many households, yes — it's faster (often one visit instead of two to three) and avoids any chemical residue concerns, which matters more for households with young children, pets, or anyone wanting the fastest possible resolution.

 

We'll always specify whether the quoted price includes a guarantee period follow-up visit or whether that's priced separately — ask directly if it isn't clear on your quote.

 

No — and this is one of the most common ways bed bug treatment fails. Bed bugs spread to furniture, skirting boards, and wall cavities beyond the bed itself, so partial treatment usually means the infestation returns and you end up paying for a second, more extensive job.

 

This depends on the cause and your tenancy agreement — see our guide on bed bugs in rented flats for a full breakdown of typical responsibility.
