How we handle AHU cleaning in High Garrett
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers dampers and louvres, supply and extract fans and internal panels, and common reasons people get in touch are dirty coils holding back the airflow and dust built up on fan impellers.
In a village or hamlet like High Garrett, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in High Garrett
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Most sites get in touch when they notice something like this:
- Rooms that smell stuffy when the system runs
- Debris and leaves in the fresh air intake
- Coils clogged with dust and debris
- Dust built up on fan impellers
Healthcare buildings such as Braintree Community Hospital, about 2.6 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near High Garrett, yours matters too.

What affects the cost of AHU cleaning
There’s no set price list, because no two systems are the same. The quote depends on:
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- A single visit or a regular plan
- What state the system is in
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
- The roof, plant room or outside wall the system runs to
We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or use the quote form.
What happens if it’s left?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A planned visit to High Garrett is easier to arrange than an emergency callout.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

Ventilation in High Garrett buildings
There are about 6 caring premises (care homes, nurseries and hospitals) on the FSA’s food hygiene register across High Garrett and its immediate surroundings (about a mile and a half). Where buildings like these have air handling units, filters, coils and drain trays need regular attention. High Garrett, about 40 miles from central London, is within our usual area. Evening, overnight and weekend visits are all possible. Braintree Community Hospital is the nearest hospital, about 2.6 miles south-west of High Garrett. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For schools like Bocking Church Street Primary School, the holidays are the usual time to inspect and clean ventilation.
High Garrett is about 2 miles north of Braintree, in Essex. Whether your site is in the middle of High Garrett or further out, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Across Essex, we cover 644 places, High Garrett among them. There’s also a page for Chelmsford, roughly 13 miles from High Garrett.
Every address in CM7 is covered for AHU cleaning, from busy streets to back roads. We cover sites on High Garrett, Grove Field and Sunnyfields Road and the roads around them. Close by, we work in Bocking Churchstreet (1 mile south-west), Gosfield (2 miles north), Beazley End (2 miles north-west), Church End (3 miles west) and Shalford (4 miles north-west). We also work in nearby towns such as Colchester (14 miles east), Chelmsford (13 miles south), Maldon (13 miles south), Witham (8 miles south), Camulodunum (13 miles east) and Halstead (3 miles north-east).
Landmarks near High Garrett
Locally, jobs take us to businesses close to Tabor Academy and Bocking Blackwater and the streets around them. For rail, the closest station is Braintree station, roughly 2.6 miles south. Other landmarks nearby include Tudor House Museum (Braintree) (1.7 miles south-west) and Braintree Community Hospital (2.6 miles south-west). Not far away are Belcher's and Broadfield Woods.
Between visits
Simple habits between visits make a real difference. We recommend:
- Plan the next inspection before the last report gets filed away
- Clear leaves and litter away from the intake
- Flag stale or damp smells in the supply air
- Stick to the filter change plan
You receive a TR19® certificate and a photo report after the clean. They belong in the plant or maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It does not solve:
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
- The supply and extract ducts, quoted separately
If you’re not sure, just phone us on 0345 646 2711, or email photos and we will give you a straight answer.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
High Garrett questions
Can you get to a site in High Garrett?
Yes. Villages and rural sites across the South East are part of our work, High Garrett included. A survey first, from pictures or a visit, means we arrive with the right kit.
Do you offer AHU cleaning in High Garrett?
Yes, High Garrett is covered. To start, give us a ring on 0345 646 2711, or email photos with a few pictures of the system.
What is TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. The work itself takes anything from half a day for one small unit to several shifts for a plant room full of them. Photos of the system and how to reach it help us plan a visit to High Garrett.
- We agree a shutdown window that suits the building.
- 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.
- After pictures are taken and the certificate issued.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Make sure someone can let us in and lock up afterwards
- Plan for cooking equipment or plant to be off before we arrive
