Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Copse Hill and across Greater London. Larger estates can be phased building by building to keep disruption down.
Records are where multi-site compliance often slips. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
About our AHU cleaning in Copse Hill
We clean the parts of the unit where dirt and moisture gather: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. The work covers drain trays, heating and cooling coils and filter sections, and people most often call us about dirty coils holding back the airflow and air handling units with blocked filters.
London buildings tend to keep their plant on the roof or below ground, so work in Copse Hill is often done in the evening or at weekends. Parking and loading are agreed with the building in advance.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
Copse Hill questions
Can parking be tricky for a job in Copse Hill?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, usually makes it simpler.
Can you come to Copse Hill after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Copse Hill needn’t be disturbed. Just give us a ring on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and the quote will give you a clear idea.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
How much notice do you need?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
Do you offer maintenance contracts?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and floors and nearby surfaces are sheeted. The work itself takes from a few hours for a compact unit to a day or more for a large one. In Copse Hill, as across London, we typically work overnight or at weekends and hand the site back ready to open.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Mention any parking or loading restrictions
- Clear loose items from the work area
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
To get a fixed quote, phone us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

What affects the quote in Copse Hill
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- The condition we find in the survey
- Working hours and out-of-hours timing
- Parking and loading at the site
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.
Asking for a quote
Before you ask for a quote, gather:
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- Photos showing the whole system and its surroundings
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, call us on 0345 646 2711 or drop us a line.
Do you need AHU cleaning in Copse Hill?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Most sites get in touch after spotting something like this:
- Intake sections clogged with outdoor debris
- Dirty coils holding back the airflow
- Stale or musty smells from the ventilation
- Units that have only ever had filter changes
Workplaces around Raynes Park station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts.
What to look for in a quote
- Whether VAT is included
- Exactly which parts of the system are covered
- Proof of insurance
- How areas they cannot reach will be recorded
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Why it’s worth doing now in Copse Hill
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so there are no surprises.
What you get with us
- Fixed quotes from a survey or pictures
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Survey first, then a fixed quote
- Every visit written up, with pictures
