How we handle AHU cleaning in Fox Street
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. Common call-outs are for drain trays holding standing water and units needing a clean before a new tenant or handover, on heating and cooling coils, internal panels and supply and extract fans.
Work in a small place like Fox Street starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Ventilation in Fox Street buildings
Food Standards Agency data includes about 6 schools, colleges and universities and about 14 hospitals, care homes and childcare premises within 1.5 miles or so of the middle of Fox Street. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Colchester Hospital is the nearest hospital, about 2.2 miles west of Fox Street. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Fox Street is about 53 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible.
Colchester Hospital, about 2.2 miles west, is the nearest hospital to Fox Street, and healthcare sites of every size need their supply air kept clean.
Fox Street is about 3 miles north-east of Colchester, in Essex.

How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
Between visits
Results last longer with the right care. Here’s what we suggest:
- Keep inspection doors on the unit in good order
- Plan the next inspection before the last report gets filed away
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. For a village or hamlet like Fox Street, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
How to get a quote
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or email us.
Advice
Fox Street questions
Can you get to a site in Fox Street?
Yes. Fox Street is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
Can you come to Fox Street after we close?
Yes, we can come after you close and finish before you open. That way a site in Fox Street does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Will you repair the fan or motor?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
How long does it take to clean an air handling unit?
As a guide, it takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
How much does AHU cleaning cost?
We do not publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before we start.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
If in doubt, call us on 0345 646 2711 or drop us a line and we’ll say what we think.
Where we work
- Internal panels
- Dampers and louvres
- Filter sections
- Heating and cooling coils
- Drain trays
- Supply and extract fans
Do you need AHU cleaning in Fox Street?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
These are the problems we see most often:
- Fan sections that haven’t been cleaned in years
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Dust-coated heating and cooling coils
For schools like Roach Vale Primary School, the holidays are the usual time to inspect and clean ventilation.
What your quote should include
- Whether they’re fully insured
- When they can work, and whether that is outside your opening hours
- Whether the quote shows VAT
- Whether the quote is based on a survey or pictures
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Leave it or put it right?
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. It’s worth booking a check, because nobody sees inside a duct day to day.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
