AHU cleaning for kitchens and businesses in Little Laver
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers internal panels, drain trays and supply and extract fans, and common reasons people get in touch are air handling units never cleaned inside and dust built up on fan impellers.
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’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
Aftercare tips
After the visit, a few habits help the work last:
- Diary the inspection date recommended in the report
- Keep filter changes on time and recorded
- Don’t ignore odours coming through the grilles
- Make sure condensate is draining away
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
Your questions about AHU cleaning in Little Laver
Can the work in Little Laver be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. It means the site in Little Laver keeps running as normal. Tell us your opening hours when you ask for a quote.
Is Little Laver in your area for AHU cleaning?
Yes. Our area runs across London and the South East, Little Laver included. You can give us a ring on 0345 646 2711, or send details by email and let us know what needs doing.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
What do you do to protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.

When to call us in Little Laver
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, building up layer by layer.
Any of these means the system needs a check-up:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Dirty fans and fan housings
- Condensate trays that will not empty
In Little Laver, we look inside the system before deciding what needs cleaning.
Questions to ask before you book
- When they can work, and whether that’s outside your opening hours
- What insurance they carry
- Which accreditations they hold, and whether you can check them
- Whether they recommend a next date
How the visit works
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. A few photos of the system help us make the most of a visit to a place like Little Laver.
- 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.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
- Find the previous report, if there is one
How to get a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Why it’s worth doing now in Little Laver
Stuffy rooms and stale smells in a building in Little Laver can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. With notice, the visit to Little Laver can be fitted around your bookings and events.
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before work begins.
