We permanently eliminate persistent food, grease and kitchen smells from London properties using a comprehensive multi-stage process — specialist degreasing treatment, ULV fogging and monitored ozone.
Cooking smells are among the most commonly underestimated odour problems in residential properties. They are also among the hardest to fully eliminate. What most people experience as a temporary smell after cooking is, in reality, a complex chemical deposit that accumulates on every surface in the property over time.
During cooking, hundreds of volatile organic compounds are released into the air — from fat and oil aerosols, smoke particles, protein degradation products and flavour compounds. These particles are invisible and extremely fine. They travel throughout the property and settle on walls, ceilings, curtains, upholstery, carpets and even inside cupboards. Over months and years, particularly in properties with poor ventilation or where strong cuisines are regularly prepared, this builds into a layer of embedded residue.
Strong cuisines — particularly South Asian, Middle Eastern and East Asian cooking with high use of spices, oils and frying — produce some of the most persistent and identifiable odours. Curry smell, fish odour and deep-frying smells are particularly common concerns for London landlords, as they are highly recognisable and can deter potential tenants and buyers immediately upon entering a property.
Surface cleaning removes visible grease but cannot extract odour compounds that have penetrated into wall paint, plaster, ceiling materials and fabric fibres. Ventilation reduces airborne concentrations temporarily but does nothing to address the embedded residue — which continues to off-gas as the property warms up. Air fresheners and scented candles mask the smell briefly but the cooking odour returns as soon as the masking agent fades.
Our experience shows that lasting results require a staged approach: first breaking down and removing the grease and residue from surfaces, then penetrating fabrics and air spaces with specialist fogging, and finally applying monitored ozone to neutralise residual compounds throughout the property.
Cooking odour treatment works best when it addresses contamination at every layer — surface grease and residue, embedded compounds in fabrics and walls, and airborne odour molecules. Our staged approach consistently delivers the most thorough results.
Based on our experience treating cooking-odour-affected properties across London, a staged process consistently delivers the best results. We begin with specialist degreasing to remove the physical residue from surfaces, then use ULV fogging to reach fabrics and wall cavities, and finish with monitored ozone treatment to neutralise residual airborne compounds. Each stage targets a different layer of contamination.
We assess the extent of cooking odour, identify the most affected rooms and surfaces, and recommend the most appropriate treatment package. We always advise honestly about what to expect before any work begins.
All affected hard surfaces are treated with professional degreasers and specialist odour-removal chemicals. For heavily contaminated kitchens, all surfaces are physically cleaned by hand to remove built-up grease, oil and food residue before fogging begins.
Specialist odour-neutralising solution is applied throughout the property as a fine mist. The mist penetrates curtains, carpets, soft furnishings, ceiling voids and wall cavities — reaching cooking compound deposits that surface treatment cannot access.
Industrial ozone generators neutralise residual cooking compounds and VOCs in the air and on treated surfaces. We monitor O₃ concentration in real time throughout. Ionisation provides final air purification, removing remaining odour particles.
The property is thoroughly ventilated and safe re-entry confirmed. We provide aftercare guidance on kitchen ventilation habits and extraction maintenance to prevent future odour buildup.
Most operators apply a single treatment and leave. Our process is different — we degrease surfaces first, fog inaccessible areas, then apply ozone and monitor its concentration in real time to verify that effective treatment levels were reached throughout every room.
We treat all hard surfaces with professional degreasers before fogging or ozone — removing the physical residue that is the primary ongoing source of cooking odour. This is the step most operators skip.
Our cold-fog equipment delivers specialist neutraliser throughout the property — into curtains, carpets, soft furnishings and air spaces where cooking compounds have settled beyond the reach of surface cleaning.
We measure O₃ concentration throughout treatment with professional instruments, verifying effective levels were reached and maintained in every room.
If cooking odour has penetrated deeply into wall materials or the kitchen requires significant physical cleaning before treatment, we advise you honestly before any work begins.
We work flexibly across Greater London, including evenings and weekends, with same-day or next-day availability for urgent end-of-tenancy or pre-sale requirements.

The right package depends on how long cooking odour has been accumulating, the type of cooking involved and how deeply residue has penetrated surfaces. We always recommend the most appropriate option honestly.
For light to moderate cooking smell in a property where hard surfaces have already been thoroughly cleaned. Suitable for occasional cooking odour or where the kitchen has been recently deep-cleaned before treatment.
Our most popular package for established cooking odour. Combines specialist degreasing of kitchen and affected surfaces with ULV fogging throughout the property and monitored industrial ozone treatment.
Full remediation for heavily contaminated properties where cooking odour has built up over years. Includes thorough manual cleaning of all surfaces, full degreasing treatment, ULV fogging throughout and monitored ozone.
The effectiveness of cooking odour removal depends significantly on whether grease and food residue has been adequately addressed from kitchen surfaces before treatment. Where cooking odour has penetrated into wall plaster or ceiling materials beyond the surface layer, additional redecoration may deliver better long-term results alongside professional treatment. We always provide an honest assessment before any work begins.
In the majority of cases, yes. Our multi-stage process addresses cooking odour at every layer — physical degreasing of surfaces, ULV fogging of fabrics and air spaces, and monitored ozone treatment. Where cooking odour has been building for years, we will advise honestly on what to expect and whether additional redecoration might be advisable alongside treatment.
Yes — this is one of the most common requests we receive from London landlords and estate agents. Curry and spice odours are among the most persistent cooking smells because spice volatile compounds bond strongly with surfaces and fabrics. Our advanced degreasing and fogging treatment, followed by monitored ozone, delivers consistently good results for spice and curry odour. For properties with years of accumulated odour, our Complete package is recommended.
Cooking odour returns because cleaning removes visible grease but cannot extract the volatile compounds that have penetrated wall paint, plaster and fabric fibres. As the property warms up — particularly in summer or when the heating is on — these embedded compounds off-gas back into the air. Surface cleaning and ventilation only address what is accessible on the surface; a professional treatment reaches the embedded residue that surface methods cannot.
Treatment duration depends on the property size and severity of contamination. The Essential package for a lightly affected flat typically takes 4–6 hours. The Advanced package (degreasing + fogging + ozone) for a 2-bedroom property generally takes 8–14 hours. The Complete package, which includes full manual surface cleaning, may require 1–2 days. We will provide a clear timeframe during your free quote.
Yes — landlord and end-of-tenancy work is a significant part of what we do. We regularly treat properties where previous tenants have left persistent cooking odour, preparing them for viewings, new tenancies or sale. We can provide documentation of the treatment for your records. Same-day and next-day appointments are available across London Zones 1–6.
When our full staged treatment is carried out and cooking odour residue has been adequately addressed at the surface level, results are typically excellent and long-lasting. In properties where odour has penetrated deeply into wall plaster or where significant redecoration is needed, treatment will deliver a major improvement — but we will advise you honestly about the best overall approach before any work begins.
Cost depends on property size, type of cooking odour and severity. As a guide: Essential from £390, Advanced (degreasing + fogging + ozone) from £595, Complete remediation from £850. Contact us for a free, no-obligation quote tailored to your specific property.
Yes. Shared kitchens in HMOs and communal cooking areas in serviced apartments or managed properties often develop the most severe cooking odours due to continuous use by multiple occupants. We have experience treating large shared kitchens and communal areas as well as individual rooms affected by cooking smells from shared spaces. Contact us to discuss your specific property.
