About our AHU cleaning in St Vincent's Hamlet
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Common call-outs are for coils clogged with dust and debris and blocked condensate drains and slimy trays, across filter sections, internal panels and supply and extract fans.
Somewhere as small as St Vincent's Hamlet, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

When something else is needed

Other services in St Vincent's Hamlet
Multi-site and managed buildings
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Keep the certificate and photo report with the plant records
- Report musty smells from the vents straight away
- Do not store bins or materials near the intake
- Report water on the plant room floor
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Leave it or put it right?
Standing water in a drain tray doesn’t clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. It’s simpler to plan the work at St Vincent's Hamlet now than to arrange it in a hurry later.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

What affects the quote in St Vincent's Hamlet
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- The size of the system
- Site requirements such as sign-in and permits
- How many systems or sites are involved
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
Photos and a few facts are often enough to price the work. Useful things to send:
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The paperwork from the last visit, if you have it
- Where the plant sits or the system leaves the building, such as a roof or outside wall
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Then give us a ring on 0345 646 2711 or drop us a line.
How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. We agree a date with you, plan the drive to St Vincent's Hamlet and turn up when the site is quiet.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Let us know about parking and loading
- Clear the space around the work
- Dig out any earlier paperwork for the system
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

Staff cleaning versus specialist work
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Yes, we can come after you close and finish before you open. Your customers, staff or residents in St Vincent's Hamlet needn’t be disturbed. Your opening times are the first thing we ask for.

What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.

Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
