Common questions in Farleigh
Do you work at weekends in Farleigh?
Yes, evening, overnight and weekend work is normal for us. That way a site in Farleigh doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Farleigh within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Which kinds of sites do you work on?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
What about areas you cannot get to?
We record them on the report, with pictures where possible, and we tell you what would make it reachable, for example new access panels.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
AHU cleaning for kitchens and businesses in Farleigh
Our AHU cleaning covers sites in Farleigh and the rest of Surrey, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. The work covers heating and cooling coils, supply and extract fans and dampers and louvres, and people most often call us about dust-coated heating and cooling coils and air handling units due a clean after building work.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What affects the quote in Farleigh
Your quote is based on your site. We take into account:
- How easy every part is to reach
- The scale of the work
- How many systems or sites are involved
- Any permits to work or inductions
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you’ll get one fixed quote.
Helping us quote
When you contact us, these details help:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Between visits
Here’s the after-treatment advice, short and simple:
- Check the drain tray is emptying during routine visits
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Do not ignore odours coming through the grilles
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
When to call us in Farleigh
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Dirty fans and fan housings
- Dirty coils holding back the airflow
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
Hospitals such as Warlingham Park Hospital (about 0.6 miles south) show how much a building can rely on clean ventilation, and smaller healthcare sites near Farleigh are no different.
What your quote should include
- Proof of insurance
- Whether the work can be done while the site is closed
- When the next visit should be, and why
- How areas they can’t reach will be recorded

When it’s something else
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It will not put right:
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
- Faulty motors, drives or bearings
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before booking.
Parts of the system we cover
- Internal panels
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Supply and extract fans
- Drain trays
Staff cleaning versus specialist work
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Part by part
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
The process
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. For a village or hamlet like Farleigh, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Move anything stored near the system
- Let us know about permits to work or site inductions
- Let us know how we reach the system, including roofs, risers and plant rooms
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or email photos.
