Odour Removal Cost Overview
Professional odour removal in London typically costs between £495 and £1,350+ (ex. VAT) for residential properties, depending on the type of odour, the size of the property and which treatment package is required. Unlike carpet cleaning or painting, odour removal is not priced purely by square footage — the chemistry of the smell matters as much as the space.
The three main cost drivers are: the odour type (some require specialist chemicals, others respond to fogging and ozone alone), the size of the property, and whether physical surface cleaning is needed before chemical treatment can begin.
Cost by Odour Type
Different odour types require different treatment approaches, which affects the cost. Here is a breakdown of typical price ranges for the most common odour situations in London:
| Odour Type | Typical Treatment | Price Range (ex. VAT) |
|---|---|---|
| 🚬 Smoke & cigarette | Surface treatment + fogging + ozone | £695 – £1,350+ |
| 🐕 Pet & urine | Enzyme treatment + UV inspection + fogging + ozone | £695 – £1,500+ |
| 🍳 Cooking & curry | Degreasing + fogging + ozone | £495 – £1,350 |
| 🎃 Mould & damp | Biocide treatment + fogging + ozone | £695 – £1,350+ |
| 👺 Vape & e-cigarette | Surface treatment + fogging + ozone | £495 – £950 |
| 🐀 Rodent & dead animal | Biocide disinfection + fogging + ozone | £850 – £1,800+ |
| 🔑 Previous tenant (mixed) | Multi-type treatment + fogging + ozone | £695 – £2,000+ |
| 🏢 Office & commercial | Source treatment + HVAC fogging + ozone | £695 – £3,000+ |
Why ranges vary: A 1-bedroom flat with light cooking odour costs significantly less than a 4-bedroom house with 10 years of tobacco smoke embedded in every surface. The ranges above reflect real-world variation — the best way to get an accurate figure is a free assessment.
What Affects the Price?
The 5 Main Cost Factors
Property size
Larger properties require more treatment agents, more ozone machines and more time. A studio flat costs considerably less than a 5-bedroom house.
Severity of contamination
Light residual odour after a short tenancy responds to fogging and ozone alone. Heavy contamination built up over years requires surface treatment, physical cleaning and multiple treatment stages.
Odour type and chemistry
Some odours (mould, pet urine, rodent) require specialist biocide agents in addition to fogging and ozone. These add to the cost but are non-negotiable for effective treatment.
Access and scheduling
Out-of-hours treatment for commercial premises (evenings/weekends) may attract a scheduling premium. Residential treatments carried out during business hours are standard pricing.
Documentation requirements
Treatments requiring EHO-suitable documentation or formal reports (food businesses, landlord records) are covered by the Advanced and Complete packages.
Cost by Property Size
As a rough guide, here is how property size typically affects the cost of an Advanced package (the most common treatment for residential odour):
| Property Size | Typical Duration | Advanced Package (ex. VAT) |
|---|---|---|
| Studio / small 1-bed flat | 3–6 hours | from £695 |
| 1–2 bed flat | 6–10 hours | from £850 |
| 2–3 bed house | 10–16 hours | from £1,100 |
| 4-bed+ house | 16–24 hours | from £1,500 |
| Commercial (up to 1,500 sq ft) | 8–14 hours | from £1,200 |
| Commercial (1,500–4,000 sq ft) | 14–24 hours | from £1,800 |
Is Professional Odour Removal Worth the Cost?
For landlords and estate agents, the answer is almost always yes. A property sitting vacant for an extra 2–3 weeks because viewers are put off by a smell will cost more in lost rent than the treatment itself. On a London 2-bedroom property renting at £2,000/month, three extra weeks vacant represents approximately £1,500 in lost income — significantly more than the cost of treatment.
For homeowners preparing to sell, persistent odour can deter buyers and suppress offers. Research consistently shows that smell is one of the most immediate negative triggers at a property viewing — and unlike repainting or cleaning, it is not something a buyer can easily overlook.
How Do Our Prices Compare?
For context, specialist odour removal companies in London typically charge between £834 and £2,280+ (inc. VAT) for a standard residential treatment, with some providers charging £4,000–£5,400+ (inc. VAT) for multi-day intensive remediation programmes. Our pricing reflects a focused, efficient approach that delivers excellent results without unnecessary overhead — and all prices are quoted transparently before any work begins.
The cost of doing nothing is often higher than the cost of treatment. We are happy to discuss your specific situation and give an honest assessment of whether professional treatment is the right choice — including whether there are aspects of the problem that should be addressed first.
What Is Included in Each Package?
All packages include a free site assessment, real-time ozone monitoring, safe re-entry confirmation and same-day or next-day availability across London Zones 1–6. Here is what each tier covers:

- Industrial ozone treatment throughout the property
- Real-time O₃ concentration monitoring
- Ionisation and air purification

- ULV cold fogging throughout all rooms
- Industrial ozone treatment and real-time monitoring
- Ionisation and final air purification
A note on results: In the great majority of cases, professional treatment delivers a significant and lasting improvement. Occasionally, where odour has penetrated deeply into wall cavities, subfloor spaces or structural materials, some residual smell may gradually re-emerge at a much lower level as the property warms up. We will always tell you honestly if we think this is a risk in your specific situation — before any work begins, not after.
Treatment documentation is available on request for all packages, suitable for landlord records or regulatory files.
