AHU Cleaning in Friar's Gate
AHU cleaning for commercial sites in Friar's Gate and across East Sussex. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
- Stale or musty smells from the ventilation
Between visits
Here’s the after-treatment advice, short and simple:
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
Stick to the filter change schedule, because good filters protect everything downstream. Log every change so it’s easy to see when the next is due.
Do not let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
AHU cleaning in Friar's Gate
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. Common call-outs are for debris and leaves in the fresh air intake and dust-coated heating and cooling coils, across dampers and louvres, supply and extract fans and filter sections.
For a building in or near Friar's Gate, access is agreed in advance and the visit is planned around the journey.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Friar's Gate: your questions answered
Can the work in Friar's Gate be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you are closed and we will book within them.
Do you cover Friar's Gate for AHU cleaning?
Yes, Friar's Gate is within the area we cover across London and the South East. A fixed quote usually follows within one working day of the survey details.
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 law, but it’s the benchmark.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
What do you need from me for a quote?
Some photos and a quick description of the system plus the address and your hours. If we need more, we will ask.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes typically come back within one working day, and emergencies are covered by our 24/7 line.
What do you do to protect the area?
By covering it before any work starts. We keep the work contained and leave the area clean.
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.
What happens on the day
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Friar's Gate, the journey is planned ahead and the visit arranged around the site’s hours.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- 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.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Clear the space around the work
- Let us know about parking and loading
- Arrange a key holder or contact on site

Advice
Multi-site and managed buildings
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 records stay tidy.
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
In-house cleaning or a specialist?
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.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
What affects the cost of AHU cleaning
Your quote is based on your site. We take into account:
- Site requirements such as sign-in and permits
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- How many systems or sites are involved
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Any previous report or certificate
- Photos showing the whole system and its surroundings
For AHU cleaning in Friar's Gate, ring 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We usually send a fixed quote within one working day.
When to call us in Friar's Gate
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
What we’re most often called out for:
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
Classrooms and halls at schools such as St John's Church of England Primary School are easiest to work in when pupils are away.
Questions to ask before booking
- What hours they’ll be on site
- How VAT is shown on the quote
- How areas they cannot reach will be recorded
- If they look at the system before pricing

Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
