TR19 inspection for kitchens and businesses in Wonersh
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. Our readings give your risk assessment real numbers to work from. If you are dealing with kitchens whose menu or hours have changed and missing access panels found on survey, we can put it right.
For a kitchen in or near Wonersh, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What affects the quote in Wonersh
Your quote is based on your site. We take into account:
- The times the site is available
- The condition of the system
- A single visit or a regular plan
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.
Asking for a quote
To speed up the quote, please include:
- Detail shots of panels, filters and grilles
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711, or email photos.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Signs you need TR19 inspection in Wonersh
Grease is fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
These are the problems we see most often:
- Checking the result of a recent clean
- Missing TR19 certificates or history
- Kitchen extract systems with no recent grease readings
- Extracts that may be over the 200 micron mean
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.
What to look for in a quote
- Which accreditations they hold, and whether you can check them
- Exactly which parts of the system are covered
- How VAT is shown on the quote
- How areas they can’t reach will be recorded
Looking after it afterwards
After the visit, a few habits help the work last:
- Diary the next grease test and clean
- Have the latest report ready for insurance renewals
- Keep canopy edges and gutters wiped down
- Store grease readings where your insurer can see them
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
How the visit works
Your staff don’t need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. We agree a date with you, plan the drive to Wonersh and turn up when the site is quiet.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down

TR19 inspection in Wonersh: the local picture
The FSA’s food hygiene register includes about 5 pubs, bars and clubs within 1.5 miles or so of the middle of Wonersh. Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Wonersh get their food hygiene inspections from Waverley council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Surrey Fire and Rescue Service covers Wonersh. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Term dates shape school work: for a school like Bramley CofE Aided Infant School and Nursery, an extract clean fits neatly into a half-term or summer break. If you run a church or community hall kitchen, near Wonersh United Reformed Church or elsewhere in Wonersh, its extract still collects grease from every lunch and event.
Wonersh is about 4 miles south of Guildford, in Surrey. Every kind of commercial site in Wonersh, TR19 inspection is something we can help with. Visits can be booked for evenings, overnight or weekends so trading is not interrupted. We cover 395 places across Surrey, from busy centres to quieter spots.
Every address in GU5 is covered for TR19 inspection, from busy streets to back roads. If you need TR19 inspection at premises on The Street, Woodyers Close and The Close or anywhere close by, our technicians can take on the work. If your site is just outside Wonersh, we cover Bramley (1 mile west), Shamley Green (1 mile south-east), Birtley Green (1 mile south), Stroud Common (2 miles south-east) and Grafham (2 miles south).

Local landmarks in Wonersh
Typical jobs here are in premises near Shalford Mill, Broadwater School and The Grantley Arms Public House. The nearest railway station is Chilworth station, roughly 1.5 miles north-east of the centre. Well-known places in the area include Surrey Police Museum (2.6 miles north-west) and Guildford Castle (2.9 miles north-west). For a walk, there’s St Martha's Hill and Silent Pool.
Multi-site and managed buildings
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 photos, 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 on a regular cycle.
What TR19 inspection can’t fix
We will not sell you work that does not address the problem, so here are the limits:
- Sections with no access, until panels are fitted
- The grease itself, which needs a full or spot clean
- Fire safety duties beyond the extract system
If you’re not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
What the work covers
- Access surveys
- Post-clean checks
- Insurer audits
- Deposit thickness tests
- Pre-clean surveys
- Wet film thickness tests
Questions from Wonersh
Is Wonersh within the area you cover?
Yes. Wonersh is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Who would carry out a food hygiene inspection at a kitchen in Wonersh?
Food hygiene inspections in Wonersh are carried out by Waverley council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you look after several sites?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do you check other contractors’ cleans?
It’s an inspection after cleaning, to show what state the system was left in, whoever did the clean.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
How much does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
