AHU cleaning in Southwark
Our AHU cleaning covers sites in Southwark and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers internal panels, drain trays and supply and extract fans, and people most often call us about coils clogged with dust and debris and condensate trays that won’t empty.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in Southwark, dust settles in the units and ducts year after year, which is what TR19® Air cleaning deals with.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
AHU cleaning around Southwark
The FSA’s food hygiene register lists about 93 schools, colleges and universities, about 52 hospitals, care homes and childcare premises and about 102 hotels and guest houses with registered kitchens or food service within roughly a mile and a half of the centre of Southwark. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. The nearest hospital to Southwark is Surrey Dispensary, about within half a mile south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours.
For workplaces around Elephant & Castle station with mechanical ventilation, cleaning can be done in the evening or at weekends. If you manage a school such as Charles Dickens Primary School, ventilation cleaning is best booked for the holidays.

Different parts, different methods
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. We clean the intake and first stage of filters along with the rest.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.

Aftercare tips
How long the results last depends on use and care. We suggest:
- Change filters on schedule and log each change
- Keep the area around the fresh air intake clear
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- When the work can happen, such as evenings, overnight or weekends
- Site rules, permits and inductions
- The number of sites or systems
- Parking and loading at the site
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we will go through it with you.
Asking for a quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see

What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. If your building in Southwark has sign-in rules, permits or key holders, mention them when you book.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Find the previous report, if there is one
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
How to get a quote
Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Southwark: your questions answered
Is parking a problem for work in Southwark?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we will book into it.
Do you clean school ventilation in Southwark in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 93 schools and colleges with food registrations within roughly a mile and a half of Southwark. Just phone us on 0345 646 2711, or email photos with your term dates and we will plan around them.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. If we need more, we’ll ask.
What do you clean inside the unit?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Why deal with it now?
Leave an AHU uncleaned and the dirt does not stay put. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. A busy site in Southwark builds up dirt and wear quickly, so putting it off makes the eventual job larger.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.

- Survey first, then a fixed quote

Signs you need AHU cleaning in Southwark
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that is the air they breathe for hours on end.
These are the problems we see most often:
- Dust built up on fan impellers
- Air handling units with blocked filters
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near Southwark, clean ventilation matters as much to you as to a hospital like Surrey Dispensary (about under half a mile south-east).
