Cosham questions
Is Cosham within the area you cover?
Yes. Cosham is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Do you do school kitchen extract cleaning in Cosham in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Cosham, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we will fit the work in.
Are the filters cleaned too?
The filters come out so the plenum behind them can be cleaned, then clean and refit them. We’ll tell you if any need replacing.
How long does canopy cleaning take?
One lightly soiled hood does not take long, but large or heavily soiled canopies take longer. We will tell you what to expect.
When do you clean the canopy?
We clean when the kitchen is closed: evenings, overnight, early mornings or weekends. Equipment under the canopy needs to be off and cool.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Canopy cleaning in Cosham
For canopies and hoods in Cosham, the work follows the same careful routine: we remove the filters, clean the plenum and housing, then degrease the canopy shell. Before and after pictures go into your report. If you are dealing with a filter housing caked in grease and smoke hanging around the canopy during service, we can help.
In a smaller place like Cosham, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. A kitchen that cooks fewer hours still builds up grease, so cleaning is planned around how much it cooks and what the readings show.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the cost of canopy cleaning
The price is fixed before any work begins. It takes into account:
- What state the system is in
- Whether several sites go on one quote
- The scale of the work
- Working hours and out-of-hours timing
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
- Any access panels or hatches you can see
- The site address and the type of premises
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Canopy cleaning in Cosham: the local picture
At about 1 mile from the coast, Cosham is close enough for sea air to matter. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. The FSA’s food hygiene register shows about 78 restaurants, cafés and canteens and about 44 sandwich bars and takeaways within 1.5 miles or so of the middle of Cosham. Where they cook under a hood, the plenum behind the filters is where grease hides. In Cosham, food businesses are inspected by environmental health officers from Portsmouth council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
If you cook for passing trade around Cosham station, the extract can be cleaned between your last and first customer. Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Cosham is Queen Alexandra Hospital, about 0.6 miles north.
Cosham is about 2 miles south-west of Purbrook, in Portsmouth. Every kind of commercial site in Cosham, canopy cleaning is something we can help with. We can work out of hours so the site keeps running. Cosham is one of 19 towns, villages and districts in Portsmouth we cover for commercial clients.

Local landmarks in Cosham

How it works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, which takes a few hours, depending on the size of the canopy and how much grease has built up. In a place like Cosham, we fit the visit around your hours.
- We look at the canopy first, from pictures or on a visit.
- Cooking equipment is left to cool and the area under the canopy protected.
- We remove the grease filters and clean the plenum and filter housing.
- We degrease the canopy shell, its seams and the grease troughs.
- Clean filters are refitted and before and after photos go into your report.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Ask for a quote
To get a fixed quote, ring 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Cosham and across Portsmouth. Work can be phased by floor, building or site to keep disruption down.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Common problems we fix in Cosham
Any canopy in Cosham that is used for cooking will gather grease in the end. It’s fuel, sitting directly over the burners, so a flare-up near a greasy hood can quickly become a fire.
Clients usually contact us after spotting one of these:
- Smoke hanging around the canopy during service
- Heavy deposits behind the grease filters
- Condensation and grease dripping together
- A hood coated in old grease
Volunteers running a hall kitchen near Church of St Philip, or anywhere in Cosham, may not know when the extract was last cleaned, and a grease test settles it.
What your quote should include
- If they look at the system before pricing
- Whether the price is fixed
- When they can work, and whether that’s outside your opening hours
- When the next visit should be, and why
What happens if it’s left?
A blocked plenum and clogged filters cut the airflow at the canopy. Smoke and heat hang around the cooking line while the fan strains. Cleaning restores the path the air should take. Around Cosham, a kitchen or building out of action is missed straight away.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711 or drop us a line for straight advice and a fixed quote.
