Common questions in Enslow
Can you get to a site in Enslow?
Yes. Villages and rural sites across the South East are part of our work, Enslow included. A survey first, from photos or a visit, means we arrive with the right kit.
Can you do AHU cleaning in Enslow?
Yes, we work in Enslow and the places around it. Just call us on 0345 646 2711, or send details by email with a few details of the site.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
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.
Do you clean the ductwork as well?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Are you accredited?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, with visits on a regular schedule.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
About our AHU cleaning in Enslow
If the units serving a building in Enslow have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. We’re often asked to deal with air handling units with blocked filters and coils clogged with dust and debris, on dampers and louvres, filter sections and drain trays.
Work in a small place like Enslow starts with agreeing access and timings.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Part by part
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.

Signs you need AHU cleaning in Enslow
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
- Fan sections that haven’t been cleaned in years
- Air handling units never cleaned inside
An inspection comes first for any ventilation job around Enslow, so the cleaning matches what’s there.

What we do, step by step
A visit follows the same order every time: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Enslow.
- 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.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Arrange a key holder or contact on site
- Make sure equipment near the work can be switched off and left to cool
- Agree a time when the area can be out of use

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- Parking and loading at the site
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
- The scale of the work
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, give us a ring on 0345 646 2711 or email us for straight advice and a fixed quote.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any access panels or hatches you can see
- The site address and the type of premises
- Problems your staff have spotted
- When the site is open and when it’s quiet
Need a price for AHU cleaning? Please ring 0345 646 2711 or use the quote form and tell us about the site. We will explain what we’d do and send a fixed quote before you commit to anything.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. 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.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Why act early in Enslow
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. It’s worth booking a check, because nobody sees inside a duct day to day.
You will not find a price list here, because each job is priced on what it involves. For a fixed quote, call 0345 646 2711 or use the quote form, and we will talk you through it.
