About our AHU cleaning in Bulbourne
If the units serving a building in Bulbourne 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. The work covers heating and cooling coils, internal panels and drain trays, and the jobs we see most are coils clogged with dust and debris and air handling units with blocked filters.
Work in a small place like Bulbourne starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with photos follows each 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 the work involves, part by part
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Drain trays
Older trays can corrode and start leaking. We record their condition with photos so repairs can be planned.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Look at the condensate drain whenever the unit is serviced
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Bulbourne questions
Can you get to a site in Bulbourne?
Yes, we work in villages as well as towns, and Bulbourne is covered. Photos of the system and directions to the site help us plan the visit.
Is AHU cleaning available in Bulbourne?
Yes. Our area runs across London and the South East, Bulbourne included. You can ring 0345 646 2711, or send details by email and tell us what needs doing.
How far ahead should we book?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
What if parts of the system can’t be reached?
We record them on the report, with pictures where possible, and we explain what access is needed, for example new access panels.
Where does the waste go?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Which parts of an air handling unit do you clean?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Do you survey before quoting?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. Then you get a fixed quote.
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. The visit itself takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Bulbourne is set by you, and the travel is our side of the planning.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Clear the space around the work
- Name a contact who can let us in at the agreed time
- Tell us where we can park and unload
Getting a quote
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
In-house cleaning or a specialist?
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.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Honest limits
In fairness, there are a few things this work won’t fix:
- Problems with the unit’s controls or sensors
- Faulty motors, drives or bearings
- A system that’s undersized for the building
If you are not sure, just give us a ring on 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.

How we price AHU cleaning
Your quote is based on your site. We take into account:
- How easy every part is to reach
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, call 0345 646 2711, or send details by email for straight advice and a fixed quote.
Helping us quote
Before you ask for a quote, gather:
- Wide photos of the system and the area around it
- Any access panels or hatches you can see
- Problems your staff have spotted
- When the site is open and when it’s quiet
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Why it’s worth doing now in Bulbourne
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Bulbourne is calmer for everyone.
You won’t find a price list here, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form, and we will talk you through it.
