Your questions about AHU cleaning in Cheshunt
Do you clean school ventilation in Cheshunt in the holidays?
Yes, out-of-term visits are normal for schools. With about 14 schools and colleges on the FSA’s register within roughly a mile and a half of Cheshunt, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can the work in Cheshunt be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply phone us on 0345 646 2711 or send us an email.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we cannot see enough, we arrange a survey.
Do you have insurance?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
AHU cleaning in Cheshunt, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from pictures or on site, followed by a fixed quote, so you know where you stand. Typical jobs include dust-coated heating and cooling coils and dirty filters cutting the airflow, on internal panels, drain trays and heating and cooling coils.
Many schools and offices in a town like Cheshunt have a mix of older and newer ventilation. The work starts with an inspection to decide what needs cleaning, so you’re not paying for more than the system needs.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Looking after it afterwards
To keep the system working properly between visits:
- Stick to the filter change plan
- File each AHU report in the maintenance log
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air, rather than waiting for a problem.
What your team can do, and what needs us
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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.
When to call us in Cheshunt
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and that’s where slime and odours start.
The symptoms we are asked about most are:
- Air handling units never cleaned inside
- Plant that needs cleaning after a refit
- Drain trays holding standing water
- Leaves and litter drawn into the unit
Healthcare buildings such as St Michaels Hospital, about 3.7 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Cheshunt, yours matters too.

What happens if it’s left?
If people in a building in Cheshunt complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. Each month of use adds to the build-up, so a site in Cheshunt is better off booking it now.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Why us?
- Fully insured
- In business since 2009
- One number for every site across the South East and London
- Fixed quotes from a survey or photos

How the visit works
Each visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, tidy up and hand over the paperwork. The visit itself takes one overnight shift for many single units, with bigger plant phased. For a site in a town like Cheshunt, tell us your opening hours, where we can park and how we reach the roof or plant.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after pictures.
Getting ready for the visit
- Dig out any earlier paperwork for the system
- Tell us the best time to work, such as after service or at a weekend
- Arrange a key holder or contact on site

Advice
What else we do in Cheshunt
How we price AHU cleaning
You’ll get a fixed price before we start. It takes into account:
- Whether several sites go on one quote
- Site rules, permits and inductions
- How easy every part is to reach
- Whether it’s a one-off visit or part of a schedule
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.
Helping us quote
We can often survey from pictures. The most useful are:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
For a fixed quote, call 0345 646 2711, or send details by email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You will normally have a quote within one working day.
Ventilation in Cheshunt buildings
There are about 14 schools, colleges and universities and about 20 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register in and around Cheshunt, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Cheshunt’s nearest hospital, St Michaels Hospital, is about 3.7 miles south-west. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. We cover Cheshunt, about 15 miles from central London, as part of our work across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
Wherever a school like Andrews Lane Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
