Commercial kitchen extraction cleaning in Tower Hill
Many insurers ask for proof that the extract has been cleaned to TR19, and some may refuse or reduce a claim when it’s missing. For a kitchen in Tower Hill, our certificate and photo report give you that record for the maintenance log. The work covers canopies and hoods, extract fans and vertical risers, and people most often call us about ductwork thick with old, hardened grease and a TR19 certificate needed for the insurer. Searching for commercial kitchen extraction cleaning in Tower Hill? We have been cleaning kitchen extracts across the South East since 2009, with a certificate and photo report after every clean.
Grease that collects out of sight, behind the filters and along the duct, is what insurers and fire officers worry about, so that is where most of the work in Tower Hill goes.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Common questions in Tower Hill
Do you work overnight in Tower Hill?
Yes. We work evenings, overnight and at weekends. That way a site in Tower Hill doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Can you clean school kitchen extracts in Tower Hill during the holidays?
Yes, holiday work suits schools best. Around Tower Hill, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What paperwork comes with a kitchen extract clean?
A TR19 certificate and a photo report. The certificate is issued through the BESCA Vent Hygiene Elite portal, and the report shows before and after photos, readings, any areas not reached and the next clean date.
What should I send you?
Where the site is, what it is and when it’s open, plus pictures of the system and your last certificate or report if you have one.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Are you a BESCA Vent Hygiene Elite member?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 sit alongside that, and we’re fully insured.
How much does kitchen extract cleaning cost in Tower Hill?
It depends on the site, so we quote each one individually. For a quote, call 0345 646 2711 or drop us a line and tell us about the site and its opening hours.
Keeping the system healthy
Looking after the system between visits is straightforward, and it helps at the next visit:
- Switch the fan on before cooking starts
- File each certificate with the fire risk assessment
- Clean grease off the canopy surfaces regularly
- Keep grease collection points emptied
If we couldn’t get into part of the duct, the report says so plainly. That is part of an honest TR19 clean, not a failing, and we can fit access panels so it’s reached next time.
Keep the outside of the canopy wiped and any grease cups emptied. It won’t replace a TR19 clean, but it slows what reaches the duct.
What happens on the day
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes a single shift for most kitchens, with long duct runs and tall risers needing more time. For a village or hamlet like Tower Hill, tell us about narrow lanes, gates and parking when you book.
- You send pictures or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- On the night, the equipment is off and cool and the kitchen is sheeted.
- Filters, canopy and plenum are cleaned, then the ducts, risers, fan and discharge.
- We re-test, photograph and send your certificate and photo report.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Let us know how we reach the system, including roofs, risers and plant rooms
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
Quotes are quick. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Honest limits
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Extraction that cannot cope with the cooking because of its design
- Ductwork that is corroded, split or leaking (that’s for a ductwork contractor)
- A grease trap that needs emptying
If in doubt, give us a ring on 0345 646 2711 or use the quote form and we’ll say what we think before you book.
Parts of the system we cover
- Vertical risers
- Plenums and filters
- Horizontal duct runs
- Discharge points
- Extract fans
- Canopies and hoods
Do you need kitchen extract cleaning in Tower Hill?
A kitchen in Tower Hill builds up grease in the same places as any other: long horizontal runs, bends, the base of risers and around the fan. Cooler sections of duct collect the most.
Look out for any of the following:
- A smoky, hot kitchen with weak extraction
- Missing paperwork after a change of operator
- Grease smells coming from the extract
- Fat running down the canopy edge
Historic houses near Tower Hill, such as Chenies Manor House about 2.8 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What to look for in a quote

Grease, kitchens and Tower Hill
Food Standards Agency data counts about 9 restaurants, cafés and works canteens in and around Tower Hill, up to about a mile and a half out. Any of them cooking under a canopy is sending grease into its ductwork every service. The fire and rescue service for Tower Hill is Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Dacorum council that sends environmental health officers to food businesses in Tower Hill. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
For schools such as Kings Langley School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 3.1 miles north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Tower Hill is about 3 miles south-west of Hemel Hempstead, in Hertfordshire. Tower Hill gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. Tower Hill is one of 381 places in Hertfordshire we cover for commercial clients. You can also see our page for London, roughly 23 miles from Tower Hill.
Work in WD4 is surveyed, quoted and booked the same way as anywhere else. Whether your site is on Stoney Lane, Nursery Gardens and Tower Hill or a nearby road, our technicians can take on the work.

What happens if it’s left?
Every week without a clean adds another layer. BESA guidance says the mean should not go above 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. The longer it’s left, the bigger the job becomes. With notice, the visit to Tower Hill can be fitted around your bookings and events.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so there are no surprises.

Part by part
Schools, hospitals and care homes
School kitchens can look lightly used but still need a TR19 clean at least every 12 months under BESA guidance. Holidays make it simple to schedule.
Extract fan and discharge
At the end of the system is the discharge, and grease can collect there too. We clean it where it can be safely reached, and any limits are recorded.
