Common problems we fix in Denvilles
However carefully a kitchen in Denvilles is run, the canopy still collects grease. That grease is fuel sitting right above the heat, so a flare-up near a greasy hood can quickly become a fire.
What we are most often called out for:
- Canopy gutters full of old fat
- An EHO comment about the canopy
- Filters that never seem to stay clean
- A plenum thick with grease behind the filters
Term dates shape school work: for a school like Warblington School, an extract clean fits neatly into a half-term or summer break.
What your quote should include
- If they look at the system before pricing
- What paperwork you get at the end
- When the next visit should be, and why
- Exactly which parts of the system are covered
How we handle canopy cleaning in Denvilles
Duct Doctor has cleaned canopies and hoods since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001. We are often asked to deal with canopy gutters full of old fat and a plenum thick with grease behind the filters, across plenum chambers, canopy light fittings and wall canopies.
In a smaller place like Denvilles, 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. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Denvilles kitchens: local notes
Denvilles lies within about 1 mile of the sea. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Look up Denvilles on the FSA’s food hygiene register and you’ll find about 51 restaurants, cafés and canteens and about 44 takeaways and sandwich shops within roughly a mile and a half of the centre of Denvilles. Where they cook under a hood, the plenum behind the filters is where grease hides. Environmental health officers from Havant council inspect food businesses in Denvilles. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after.
A hospital like Havant War Memorial Hospital, about 1 mile west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A kitchen near Warblington station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
Denvilles is about 1 mile south-east of Havant, in Hampshire. Across the PO9 area, we can carry out canopy cleaning at your premises. Denvilles is one of 683 towns, villages and districts in Hampshire where we work for commercial clients. There’s also a page for Portsmouth, about 6 miles away.
We work across PO9 and PO10 for canopy cleaning and the roads nearby. We cover sites on New Lane, Pook Lane and Elder Road and the roads around them. Other places close to Denvilles include Warblington (1 mile south), Havant (1 mile north-west), Emsworth (1 mile east), Langstone (1 mile south-west) and Leigh Park (1 mile north-west). We also work in nearby towns such as Gosport (9 miles south-west), Fareham (10 miles west), Horndean (4 miles north-west), Hedge End (15 miles west), Waterlooville (4 miles north-west) and Petersfield (10 miles north).
Near you in Denvilles
Around Denvilles, our work takes us to kitchens and buildings near Six Bells pub, St Albans Church and Fairfield Infant School, among other places. There’s a railway station in Denvilles itself: Warblington station. A little further out are Warblington Castle (0.7 miles south) and Havant War Memorial Hospital (1 mile west). Not far away are Brook Meadow (Emsworth).
Keeping the system healthy
After the visit, a few habits help the work last:
- Check all filters are fitted before service
- Keep the fan on through service
- Tell us when the canopy starts to drip
- Clean the hood’s outer surfaces daily
Where the canopy is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. Where only the canopy is done, the report says so clearly.
A daily wipe of the hood keeps fresh grease from baking on. It won’t replace a professional clean, but it slows the build-up you can see.
Common questions in Denvilles
Can you clean school kitchen extracts in Denvilles during the holidays?
Yes, holiday work suits schools best. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Denvilles. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you get to a site in Denvilles?
Yes. Denvilles is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Who has the legal duty for fire safety?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do we need to close while you work?
Not typically. Visits are timed for when the area is closed, such as overnight or at a weekend, so the site can carry on as normal.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- A dirty extract fan further along the system
- A light fitting that doesn’t work
- Filters that no longer seal in the housing
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
Where we work
- Island canopies

Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so each one has its own record.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
What affects the quote in Denvilles
The quote reflects the site in front of us. We consider:
- How many systems or sites are involved
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- A single visit or a regular plan
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- Your last certificate, test record or report
For a fixed quote, call us on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
What we do, step by step
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes an hour or two for one small canopy, longer where there are several. In a place like Denvilles, we fit the visit around your hours.
- We start by checking the canopy and what’s behind its filters.
- Equipment is turned off and cooled, and the area under the canopy is protected.
- Thick grease is scraped away before the canopy is degreased.
- Plenum, housing, troughs and canopy are all cleaned and checked.
- You get pictures of the result and a recommended date for the next clean.
How to prepare
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
- Tell us about site rules, permits or sign-in
Ask for a quote
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before work begins.

Island canopies
An island canopy is open on all sides, so every face can collect grease. Each face is cleaned inside and out.
School and staff canteen kitchens
School and canteen kitchens often cook to set hours, which makes a canopy clean easy to schedule. We often clean them in holidays or at weekends.
