About our AHU cleaning in Stapleford
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. We are often asked to deal with drain trays holding standing water and intake sections clogged with outdoor debris, on internal panels, drain trays and filter sections.
Somewhere as small as Stapleford, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Stapleford: your questions answered
Can the work in Stapleford be done at night or at weekends?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Stapleford needn’t be disturbed. When you call 0345 646 2711 or send us an email, mention when the site is quiet.
Do you clean school ventilation in Stapleford in the holidays?
Yes, out-of-term visits are normal for schools. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Stapleford. Send us your term dates when you give us a ring on 0345 646 2711, or send details by email, and we will fit the work in.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. We fit the work around how the site operates.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
How long does it take to clean an air handling unit?
Expect it to take from a few hours for a compact unit to a day or more for a large one. Size, layout and how dirty it is decide the rest, and we will confirm the time when we quote.
How much does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will usually reply within one working day.
How far ahead should we book?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
For landlords and multi-site operators
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.
We regularly work with managing agents. Send the address, what’s needed and how access works, and we will send a fixed quote.
How it works
We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. 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 Stapleford, 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.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- 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.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Mention any parking or loading restrictions
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site
Get a fixed quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Aftercare tips
Here’s the after-treatment advice, in brief:
- Keep the certificate and photo report with the plant records
- Note any water around the unit or leaks below it
- Stick to the filter change plan
- Do not store bins or materials near the intake
Restart the unit with your site team or maintenance contractor once we’ve finished. Check the drain tray is emptying over the first few days to confirm water is draining away.
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.

Why it’s worth doing now in Stapleford
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. Our emergency line runs 24/7, but a planned visit to Stapleford is calmer for everyone.

Signs you need AHU cleaning in Stapleford
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that’s the air they breathe for hours on end.
Common reasons sites call us are:
- Plant that has been serviced but not cleaned
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Dirty coils holding back the airflow
Wherever a school like Stapleford Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
