Canopy and hood cleaning in Harefield, Southampton
Looking for canopy cleaning in Harefield? We diagnose first, fix the price and book the work around your hours, finishing with a written report and pictures.

- An EHO comment about the canopy
- Greasy streaks across the canopy
How we handle canopy cleaning in Harefield
Think of the canopy as the mouth of the extract. If it’s coated in grease, everything downstream gets more of it. Our diagnosis starts there, and the cure is a thorough clean of the hood, the plenum and the filter housing. The work covers plenum chambers, grease gutters and island canopies, and the jobs we see most are an EHO comment about the canopy and filters that clog soon after cleaning.
Size doesn’t change the work: a kitchen in a place like Harefield gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Never run the range with a filter out
- Avoid harsh scourers that scratch the canopy
- Check filters aren’t leaving gaps
- Flag any change in how the canopy behaves
Anything worth knowing goes into the report: damaged filters, gaps around the housing or troughs that need emptying more often. It’s a short list of what to watch, not a sales pitch.
Run the extract for as long as anything is cooking. Turning the fan off early lets vapour settle on the hood.
Why it’s worth doing now in Harefield
Fresh grease comes off far more easily than old. Over months, the heat hardens it into a stubborn coating, which makes a later clean slower and harder. In a smaller place like Harefield, a site that has to close is felt quickly.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or email us for straight advice and a fixed quote.

Honest limits
We will always give you a straight diagnosis, so here’s what this work can’t put right:
- Grease filters too damaged to refit (they need replacing)
- A fan that can’t pull enough air because it’s worn out
- Faulty canopy lights or wiring (a job for an electrician)
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly.

What canopy cleaning looks like in Harefield
Harefield is within about 3 miles of the coast. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. The Food Standards Agency lists about 15 pubs and bars as registered food businesses within 1.5 miles or so of the middle of Harefield. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Harefield is Hampshire and Isle of Wight Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
South Stoneham House, about 1.9 miles north-west, is one of the historic houses near Harefield; if you run event catering at a venue like that, cleans can be booked between functions. If you look after a school kitchen, at a school such as Harefield Primary School or anywhere near Harefield, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Moorgreen Hospital (about 1.1 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

How we price canopy cleaning
Before we fix a price, we need to know a few things. We check:
- Whether we need access equipment or extra panels
- A single visit or a regular plan
- The size of the system
- Travel, parking and unloading
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before work begins.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Whether it’s one building or many, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Harefield questions
Which council inspects kitchens in Harefield?
Food hygiene inspections in Harefield are carried out by Southampton council. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is canopy cleaning any different in a coastal place like Harefield?
It can. Being within about 3 miles of the sea means more corrosion on metalwork in Harefield than inland. Rooftop fans, discharge cowls and fixings are checked for corrosion as well as grease.
Which canopies and hoods do you clean?
We clean canopies in commercial kitchens of every kind. The routine stays the same whatever the kitchen, with the equipment off and cool.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What types of premises do you cover?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and waste is contained as we go. At the end, the area is cleaned down.
Does a canopy clean meet TR19?
Canopy cleaning is part of TR19, not the whole of it. We will make clear on the report which parts were cleaned, so your records stay accurate.
Do you provide pictures of the cleaned canopy?
Before and after pictures go into a report that lists what was cleaned and anything we couldn’t reach. A full TR19 clean adds a certificate from the BESCA Vent Hygiene Elite portal.

What else we do in Harefield
In-house cleaning or a specialist?
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
How it works
Your trading hours come first. 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 job takes a few hours for most canopies. Your opening hours decide when we come to Harefield, not ours.
- First the canopy is surveyed, by pictures or in person.
- Cooking equipment is left to cool and the area under the canopy protected.
- With the filters out, the plenum and housing are cleaned back.
- The canopy is cleaned inside and out, including troughs and seams.
- Filters go back, the area is cleaned down and pictures are taken.
Getting ready for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Clear the space around the work
