- Duct runs that can’t be reached
- Fat dripping from the ductwork
- Readings above 200 microns from a grease thickness test
When to call us in Wonersh
A duct with too few access doors cannot be fully cleaned. Stretches with no way in may never have been touched, and the grease there keeps building out of sight.
Common reasons sites call us are:
- Years of grease along the duct floor
- Sections of duct with no access panels
- Smells of old cooking grease from the ductwork
- A duct nobody has opened in years
If your kitchen is in a listed or historic building, like the houses around Wonersh (Chilworth Manor is about 1.7 miles north), fitting access panels needs care.
Questions to ask before you book
- Whether they’re fully insured
- How VAT is shown on the quote
- Whether a survey comes first
- Whether the price is fixed
How we handle ductwork cleaning in Wonersh
Many ducts were installed with too few access doors. TR19 calls for any section we couldn’t reach to be recorded, and we can fit new access panels so it’s cleaned next time. An honest report beats a guess. The work covers access panels, bends and junctions and horizontal duct runs, and the jobs we see most are stale grease odours from the duct and ductwork that has never been cleaned.
Work in a small place like Wonersh starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Looking after it afterwards
After the visit, a few habits help the work last:
- Run the extract fan throughout service
- Ask for a grease thickness test if the kitchen gets busier
- Report any grease dripping from duct joints
- File each certificate and photo report in the maintenance log
You’ll have a recommended date for the next clean, based on the readings and your daily cooking hours, in line with BESA guidance.
Run the extract the whole time the kitchen is cooking. When the air stops, grease settles in the duct, so switching off early adds to the build-up.
How the job changes from site to site
Access panels
Extra panels can be installed where there are gaps, making future cleans more complete. We will recommend where they should go.
Bends and transitions
Grease tends to pile up at elbows. We clean it back by hand and with degreaser, and test it before and after.
Ductwork cleaning around Wonersh
Food Standards Agency records list about 6 restaurants, cafés and canteens across Wonersh and its immediate surroundings (about a mile and a half). Wherever those kitchens cook under a canopy, the horizontal runs and risers need cleaning as well as the hood. Kitchens in Wonersh get their food hygiene inspections from Waverley council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Surrey Fire and Rescue Service covers Wonersh. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
Volunteers running a hall kitchen near Wonersh United Reformed Church, or anywhere in Wonersh, may not know when the extract was last cleaned, and a grease test settles it. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St. Luke’s Hospital is the nearest hospital to Wonersh, about 2.8 miles north.

- Any previous report or certificate
- Your opening hours and when the area is out of use

Wonersh: your questions answered
Who is the fire and rescue service for Wonersh?
Wonersh is in the area of Surrey Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Will you come out to Wonersh?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
What if parts of the system can’t be reached?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
What happens if there aren’t enough access panels?
Without a way in, a section can’t be cleaned properly. Those parts are listed, and we can install panels so they’re reached next time.
Can you quote from pictures?
Usually, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we’ll say so.
How much notice do you need?
Earlier is better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
How the visit works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a few hours for a short run, longer for long runs and tall risers, and we clear up before we go. Somewhere as small as Wonersh, the date and timings are agreed with you well before the day.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Name a contact who can let us in at the agreed time
- Make sure equipment near the work can be switched off and left to cool
- Clear the space around the work
How to get a quote
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.
