Little Leighs AHU cleaning
AHU cleaning in Little Leighs from ventilation hygiene specialists trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
AHU cleaning in Little Leighs, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you’re dealing with dust-coated heating and cooling coils and air handling units never cleaned inside, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Common questions in Little Leighs
Is Little Leighs within the area you cover?
Yes, Little Leighs is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you cover Little Leighs for AHU cleaning?
Yes. We work across London and the South East, and Little Leighs is part of that. You can call 0345 646 2711, or send details by email and tell us what needs doing.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What do you need from me for a quote?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711, or send details by email.
Can one contract cover all our sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and pictures.
Do you have insurance?
Yes. We carry full insurance and have been trading since 2009.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. We recommend a next date in each report.
What is TR19?
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.

Multi-site and managed buildings
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so each one has its own record.
What affects the quote in Little Leighs
The survey tells us what the work involves. We look at:
- When the work can happen, such as evenings, overnight or weekends
- Any permits to work or inductions
- Parking and loading at the site
- How easy every part is to reach
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
Asking for a quote
When you call or email, it’s useful to have:
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Wide pictures of the system and the area around it
- When the site is open and when it’s quiet
To get a fixed quote, give us a ring on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. A few photos and your last certificate or report help a lot. We normally come back within one working day.
Do you need AHU cleaning in Little Leighs?
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Keep an eye out for any of the following:
- Stale or musty smells from the ventilation
- Plant that has been serviced but not cleaned
- Blocked condensate drains and slimy trays
- Debris and leaves in the fresh air intake
If you run a surgery, dental practice or care home near Little Leighs, clean ventilation matters as much to you as to a hospital like Broomfield Hospital (about 3.5 miles south-west).
What to look for in a quote
- What’s included in the scope, part by part
- If they look at the system before pricing
- What insurance they carry
- How areas they can’t reach will be recorded
Aftercare tips
How long the results last depends on use and care. We suggest:
- Don’t ignore odours coming through the grilles
- Note any water around the unit or leaks below it
- Keep filter changes on time and recorded
- Store the TR19 paperwork where auditors can find it
You receive a TR19® certificate and a photo report after the clean. Keep both with the building’s maintenance records.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
The process
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes a single shift for a typical unit, longer for large or heavily soiled ones. A few pictures of the system help us make the most of a visit to a place like Little Leighs.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know about permits to work or site inductions
- Make sure equipment near the work can be switched off and left to cool
