What the work involves, part by part
Vertical risers
Access to risers is often limited. We record what can and cannot be reached.
Schools, hospitals and care homes
Education kitchens need TR19 inspections like any other. Readings show if the interval is right.
TR19 inspection in Mid Holmwood, done properly
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. If you have heavy grease suspected in the plenum or ducts and parts of the system left out of past cleans, we can help.
In a small place like Mid Holmwood, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What else we do in Mid Holmwood
Mid Holmwood kitchens: local notes
Food Standards Agency data counts about 4 restaurants, cafés and canteens within 1.5 miles or so of the middle of Mid Holmwood. For any of them with a canopy, measuring grease is better than guessing when to clean. Mid Holmwood is covered by Surrey 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. In Mid Holmwood, food businesses are inspected by environmental health officers from Mole Valley council. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Volunteers running a hall kitchen near Church of St John the Evangelist, or anywhere in Mid Holmwood, may not know when the extract was last cleaned, and a grease test settles it. School kitchens, at schools like St John's Church of England Primary School for example, are normally cleaned in the holidays so no lunches are lost.
Mid Holmwood is about 2 miles south of Dorking, in Surrey. Across the RH5 area, we can take on TR19 inspection. Mid Holmwood is one of 395 towns, villages and districts in Surrey where we work for commercial clients. Our Guildford page covers sites nearby, about 11 miles away.

For landlords and multi-site operators
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so each one has its own record.
Common questions in Mid Holmwood
Do you work in villages like Mid Holmwood?
Yes. Mid Holmwood is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Who enforces fire safety at workplaces in Mid Holmwood?
It’s Surrey Fire and Rescue Service, which covers Mid Holmwood. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What should I send you?
A short description and a few pictures, with the address and opening hours. We will ask for anything else we need.
What does a pre-clean survey involve?
The survey covers the whole system, grease readings and access to each section. From it, we plan the clean and quote a fixed price.
Is TR19 cleaning the law?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so following it is the sensible course.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
What do the grease readings need to be?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning straight away.
How much notice should we give?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Common problems we fix in Mid Holmwood
You can’t judge grease thickness by eye. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
These are the problems we see most often:
- An insurer’s request for a TR19 audit
- Kitchen extract systems with no recent grease readings
- Systems that need surveying before cleaning
- Sites with gaps in their extract records
If your kitchen is in a listed or historic building, like the houses around Mid Holmwood (Polesden Lacey is about 4.2 miles north-west), fitting access panels needs care.
Before you book anyone
- Whether a written report and photos are included
- Whether they’re fully insured
- Whether the whole system is included, or only the parts that are easy to reach
- What happens if part of the system can’t be accessed
What affects the quote in Mid Holmwood
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The times the site is available
- What state the system is in
- A single visit or a regular plan
- The size of the system
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What to send for a quote
When you call or email, these details help:
- The times we could work without disrupting the site
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or email us.
How it works
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. On site, the work takes a couple of hours for a typical kitchen extract system. The timing of a visit to Mid Holmwood is set by you, and the travel is our side of the planning.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, pictures and recommendations.
How to prepare
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards

Aftercare tips
No system stays clean for ever, but care slows the build-up. Our tips:
- Never cook with filters missing
- Tell us if menus or opening hours change
- Send TR19 audit reports to your insurer on request
- Keep access panels clear and unpainted
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
