AHU cleaning in Westwick Row
Our AHU cleans for sites in Westwick Row cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you’re dealing with dirty fans and fan housings and drain trays holding standing water, we can put it right.
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.
Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What staff can safely do
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. On site, the work takes from a few hours for a compact unit to a day or more for a large one. A few pictures of the system help us make the most of a visit to a place like Westwick Row.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
How to prepare
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about permits to work or site inductions
- Move anything stored near the system
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Advice
Managing agents and facilities teams in Westwick Row
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
Questions from Westwick Row
Do you clean school ventilation in Westwick Row in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 12 schools and colleges on the FSA’s register within roughly a mile and a half of Westwick Row, it pays to plan holiday dates ahead. Just phone us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Will you come out to Westwick Row?
Yes, Westwick Row is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you clean the AHU out of hours?
Yes, wherever it helps the building. We plan the shutdown window with you.
How much does AHU cleaning cost in Westwick Row?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What is TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How often should an air handling unit be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and we’ll suggest an interval after the first clean.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
What AHU cleaning cannot fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
- A system that is undersized for the building
Not sure which it is? You can call 0345 646 2711 or drop us a line and we will tell you honestly.
Parts of the system we cover
- Drain trays
- Heating and cooling coils
- Supply and extract fans
- Internal panels
- Filter sections
- Dampers and louvres
Do you need AHU cleaning in Westwick Row?
Filters that are not changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
Look out for any of the following:
- Fan sections that haven’t been cleaned in years
- Dirty filters cutting the airflow
- Units that have only ever had filter changes
- Debris and leaves in the fresh air intake
For schools like Leverstock Green Church of England Primary School, the holidays are the usual time to inspect and clean ventilation.

- Whether it’s a one-off visit or part of a schedule
- What state the system is in
- Site rules, permits and inductions

What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.

Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. A clean fan runs more smoothly.
