Commercial kitchen extraction cleaning in Highfield
Few kitchens can stop cooking for a day so the extract can be cleaned. Cleans are booked for evenings, overnight or weekends, or between services where the kitchen has a gap. Equipment is switched off and left to cool, the area is sheeted, and the kitchen is handed back ready to cook. If you’re dealing with years of baked-on grease in the ducts and rancid smells from grease in the duct, we can put it right. Some call it canopy cleaning, others extract cleaning or duct cleaning, but a proper TR19® clean in Highfield covers all of it, from the hood to the fan.
The fire risk in a kitchen extract sits in the parts nobody sees: the plenum, the duct and the fan, which is why a TR19® clean in Highfield goes well beyond the canopy.
Around a smaller place like Highfield, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Common problems we fix in Highfield
Hours of cooking are the biggest factor. BESA guidance sets minimum cleaning intervals of every 3 months for 12 to 16 hours a day, 6 months for 6 to 12 hours, and 12 months for 2 to 6 hours. They are minimums: measured grease levels set the real interval.
These are the problems we see most often:
- Cleaning needed before an insurance renewal or survey
- Rancid smells from grease in the duct
- Grease drips onto cooking equipment
- An extract that has never been cleaned to TR19
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Batchwood Hall is about 4.4 miles east), access may need planning.

- What happens if part of the system can’t be accessed
- Whether the figure could change on the day
- Whether VAT is included
Fixed quotes for kitchen extract cleaning in Highfield
The survey tells us what the work involves. We look at:
- How easy every part is to reach
- Any permits to work or inductions
- The number of sites or systems
- The times the site is available
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before any work starts.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Your last certificate, test record or report
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- A few general shots of the system
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, the quote is fixed before any work is booked.
Different parts, different methods
Canopy and plenum
The canopy catches the vapour, and the plenum behind the filters is where it first condenses. We clean both inside and out, with the filter housing cleaned too.
Extract fan and discharge
The discharge is where air leaves the building, and grease can collect there too. We clean it where it can be safely reached, and any limits are recorded.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
Common questions in Highfield
Can a school canteen extract in Highfield be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. There are about 25 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Highfield. Send us your term dates when you call us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Which fire service covers Highfield?
Fire safety enforcement in Highfield is handled by Hertfordshire Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do you work in Highfield?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Highfield.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Will my insurer ask for a TR19 certificate?
Grease in an extract is a known fire risk, so many insurers want evidence it’s being cleaned to TR19. Our certificate and photo report give you that evidence.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Why deal with it now?
After a fire, one of the first questions is often when the extract was last cleaned. Many insurers ask for proof of TR19 cleaning and may reduce or refuse a claim without it. A certificate in the file answers that question. It’s better to plan the work at a site near Highfield than wait for a failure.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.

Grease, kitchens and Highfield
Food Standards Agency records include about 26 bars, pubs and nightclubs and about 4 hotels and guest houses in and around Highfield, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for Highfield is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. It’s Dacorum council that sends environmental health officers to food businesses in Highfield. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a healthcare site, such as a hospital like Hemel Hempstead Hospital about 1.1 miles south-west, the extract may need cleaning more often than a part-time kitchen. Bursars and site managers at schools such as Yewtree Primary School tend to book extract cleaning for when the kitchen is empty.

The process
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. The work on site takes as long as the system needs, from a few hours to several planned visits, and we clear up before we go. Evenings, weekends or a closed day all work for a site in a place like Highfield.
- We start with a survey, so we know every part of the system before we quote.
- Set points are tested for grease thickness and the quote is fixed before work begins.
- Once the kitchen has closed and the equipment has cooled, we sheet and protect the area.
- We clean the canopy, plenum, filters, ducts, risers, fan and discharge.
- We test again, photograph the result and issue your TR19 certificate and photo report.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
