What affects the cost of AHU cleaning
We quote each job individually. These are the things that affect it:
- The condition of the system
- Whether it’s a one-off visit or part of a schedule
- How big the system is
- Travel, parking and unloading
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.
Helping us quote
You don’t need the technical terms. It helps if you can send:
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room

About our AHU cleaning in Royal Docks
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Clearing and cleaning the tray is central to every AHU clean. The work covers internal panels, heating and cooling coils and drain trays, and people most often call us about units that have only ever had filter changes and plant that needs cleaning after a refit.
London offices and flats often have ductwork added through successive refits, leaving sections that are hard to reach and seldom cleaned. An inspection first shows where cleaning is needed in a building in Royal Docks.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins aren’t damaged.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Aftercare tips
Results last longer with the right care. We suggest:
- Diary the inspection date recommended in the report
- Check the drain tray is emptying during routine visits
- Report stiff or damaged access doors
- Keep the certificate and photo report with the plant records
We recommend when the unit should next be inspected or cleaned, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
What staff can safely do
Some jobs should never be done in-house: 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.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
What we do, step by step
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Security desks and permits-to-work are routine in London, so let us know what your building in Royal Docks needs from us.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work, before work begins.
Advice
What we are called out for in Royal Docks
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.

- Air handling units due a clean after building work
- Dirty filters cutting the airflow

Questions from Royal Docks
Can you work in Royal Docks outside opening hours?
Yes, we can come after you close and finish before you open. The work in Royal Docks can fit around your hours. Just call 0345 646 2711, or email photos with your opening times and we’ll plan around them.
How do you handle parking and loading in Royal Docks?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Much of our London work is done overnight, which helps.
How far ahead should we book?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Will the ventilation be off while you clean?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
What if parts of the system cannot be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Do you have insurance?
Yes. Full insurance covers our work, and we have been trading since 2009.
How long will the unit be out of action?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
