AHU cleaning in South Lambeth
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from photos or a site visit, and send you a fixed quote, so you know where you stand. The work covers dampers and louvres, internal panels and drain trays, and common reasons people get in touch are blocked condensate drains and slimy trays and leaves and litter drawn into the unit.
London buildings often depend on air handling units in plant rooms or on the roof to supply fresh air. For a building in South Lambeth, dust settles in the units and ducts year after year.
Good records are part of the job. You get a written report with photos after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Different parts, different methods
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We check:
- How easy every part is to reach
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- How many systems or sites are involved
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before we start.
Helping us quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- Problems your staff have spotted
- When the site is open and when it’s quiet
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
What happens if it’s left?
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
What you get with us
- A written report with pictures after every visit
- CHAS, SafeContractor and ISO 9001

Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in South Lambeth 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 ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. 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.

Common questions in South Lambeth
Do you clean school ventilation in South Lambeth in the holidays?
Yes, holiday work suits schools best. There are about 87 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of South Lambeth. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we’ll fit the work in.
Can parking be tricky for a job in South Lambeth?
Tell us where a van can stop near your site in South Lambeth, and about any building rules on loading. Much of our London work is done overnight, which helps.
What do you need from me for a quote?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
Is a quote from pictures possible?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. A fixed quote follows.
Is South Lambeth in your area?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, South Lambeth included.
South Lambeth buildings and their air
Going by the FSA’s register, there are about 87 schools, colleges and universities, about 55 hospitals, care homes and childcare premises and about 39 hotels and B&Bs serving food within 1.5 miles or so of the middle of South Lambeth. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Getting kit to a London plant room typically means lifts, stairs and an agreed loading slot. The Gordon Hospital is the nearest hospital, about 1.1 miles north-west of South Lambeth. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run a surgery, dental practice or care home near South Lambeth, clean ventilation matters as much to you as to a hospital like The Gordon Hospital (about 1.1 miles north-west). If you run an office near Vauxhall station, its supply ductwork can gather dust for years before anyone looks inside. School buildings such as Herbert Morrison Primary School are usually done in the holidays, so classrooms aren’t disturbed.

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in South Lambeth.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Before we arrive
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
- Agree a time when the area can be out of use

What AHU cleaning can’t fix
AHU cleaning can’t fix everything, and we’d rather say so up front. It will not put right:
- Coils that are corroded or leaking and need replacing
- Airflow problems caused by the system’s design
- Problems with the unit’s controls or sensors
Not sure which it is? You can call 0345 646 2711, or email photos and we’ll tell you honestly.
