Nash Lee AHU cleaning

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
AHU cleaning in Nash Lee
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. If you are dealing with units needing a clean before a new tenant or handover and debris and leaves in the fresh air intake, we can put it right, from filter sections, internal panels and drain trays onwards.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
A written report with photos follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we’re called out for in Nash Lee
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
Keep an eye out for any of the following:
- Dirty coils holding back the airflow
- Filters that are clogged or overdue
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
Healthcare buildings such as Stoke Mandeville Hospital, about 2.3 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Nash Lee, yours matters too.
What to look for in a quote
- Whether VAT is included
- Whether they’re fully insured
- Whether inaccessible sections are listed on the report
- What records you’ll receive afterwards
In-house cleaning or a specialist?
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
If your staff spot something 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.
Why act early in Nash Lee
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a clean on your terms beats a breakdown on nobody’s. Rural sites cannot always move to another kitchen or room when something fails.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What you get with us
- In business since 2009
- Evenings, overnight and weekends, plus 24/7 emergency callout
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Full insurance on every job

What AHU cleaning can’t fix
We’d rather tell you now than book work that won’t help, so here are the limits:
- Ductwork downstream of the unit, which is a separate clean
- Mechanical faults with motors, belts or bearings
- Damaged coils beyond cleaning
If in doubt, call 0345 646 2711 or send us an email and we will say what we think.
Parts of the system we cover

Nash Lee: your questions answered
Is Nash Lee within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can you do AHU cleaning in Nash Lee?
Yes. We work across London and the South East, and Nash Lee is part of that. A fixed quote typically follows within one working day of the survey details.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can you price the work without visiting?
Often, yes. With good pictures, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Where does the waste go?
It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
How it works
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 a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Nash Lee.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
- Allow time for equipment near the work to be turned off and cool down
