How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. A name and number for whoever controls access to the building in Single Street saves time on the night.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Clear the space around the work
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

AHU cleaning in Single Street, done properly
We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you have units that have only ever had filter changes and odours coming through the supply air, we can help.
Many London buildings have had their ventilation extended and altered through several fit-outs, leaving sections that are hard to reach and seldom cleaned. In Single Street, as elsewhere, cleaning starts with an inspection of what’s there.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Single Street: your questions answered
Does London parking affect a job in Single Street?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Working overnight, as we often do in London, usually makes it simpler.
Is AHU cleaning available in Single Street?
Yes. We work across London and the South East, and Single Street is part of that. Just ring 0345 646 2711 or drop us a line with a few details of the site.
Which kinds of sites do you work on?
All kinds of commercial and public premises: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Can you quote from photos?
Normally, yes. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we’ll say so.
What does AHU cleaning cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.
Which parts of an air handling unit do you clean?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Fixed quotes for AHU cleaning in Single Street
The diagnosis comes before the price. The main factors are:
- Any permits to work or inductions
- How big the system is
- The condition of the system
- A single visit or a regular plan
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we will talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- The roof, plant room or outside wall the system runs to
- Problems your staff have spotted
- The postcode and the type of business
If you need AHU cleaning in Single Street, give us a ring on 0345 646 2711 or email us. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We normally send a fixed quote within one working day.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. London sites work long hours, and the longer a job is left, the bigger it gets.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

Landlords, agents and facilities managers
We also work for facilities teams across offices, schools and healthcare in Single Street and across Greater London. Larger estates can be phased building by building around the people who use them.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Aftercare tips
So the system stays in good health:
- Keep the certificate and photo report with the plant records
- Clear leaves and litter away from the intake
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning won’t do:
- Coils that are corroded or leaking and need replacing
- A system that is undersized for the building
- The supply and extract ducts, quoted separately
Not sure which it is? You can ring 0345 646 2711 or email us and we’ll tell you honestly before you book.
Where we work
- Heating and cooling coils
- Drain trays
- Filter sections
- Dampers and louvres
- Internal panels
- Supply and extract fans
Single Street buildings and their air
Food Standards Agency records list about 4 hospitals, care homes and childcare premises registered as food businesses within about 1.5 miles of central Single Street. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Princess Royal University Hospital is the nearest hospital, about 3.3 miles north of Single Street. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital. In London, ventilation plant is often on the roof or below ground, so the work is usually done out of hours.
Healthcare ventilation, from large hospitals like Princess Royal University Hospital (about 3.3 miles north) to small clinics, depends on clean filters, coils and ducts. Wherever a school like Cudham Church of England Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Single Street is about 5 miles south of Orpington, in Greater London.
