AHU Cleaning in Clerkenwell
Our technicians work in Clerkenwell on air handling unit cleaning. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- Plant that needs cleaning after a refit
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, 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.
AHU cleaning for kitchens and businesses in Clerkenwell
We clean air handling units for buildings in Clerkenwell and across Greater London, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include filters that are clogged or overdue and intake sections clogged with outdoor debris, on dampers and louvres, drain trays and supply and extract fans.
London offices and flats often have ductwork added through successive refits, with old runs left behind that are hard to reach. In Clerkenwell, as elsewhere, cleaning starts with an inspection of what’s there.
Good records are part of the job. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

FAQs for Clerkenwell
Can ventilation in schools around Clerkenwell be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 69 schools and colleges with food registrations within roughly a mile and a half of Clerkenwell. Tell us your holiday dates and we will book the visit for when the site is empty.
What do you need to know about parking in Clerkenwell?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
When should our AHU next be cleaned?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. Before we leave, we tidy up and clean down.
Can you clean without disrupting the building?
Yes. Evening, overnight and weekend work is all possible, so offices, schools and shops can carry on.
Will the ventilation be off while you clean?
Yes, for the time we are working on it. We can work evenings, overnight or at weekends to keep disruption down.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t legislation, but it’s the standard people check against.
Do you work with multi-site operators?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
What we’re called out for in Clerkenwell
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Clerkenwell, that’s air they breathe for hours at a time.
Common reasons sites call us are:
- Coils clogged with dust and debris
- Plant that has been serviced but not cleaned
- Rooms that smell stuffy when the system runs
- Air handling units due a clean after building work
If you run an office near Farringdon station, its supply ductwork can gather dust for years before anyone looks inside.
Questions to ask before you book
- If the quote is a fixed price or an estimate
- How VAT is shown on the quote
- Whether the whole system is included, or only the parts that are easy to reach
- Whether inaccessible sections are listed on the report
What your team can do, and what needs us
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.

Fixed quotes for AHU cleaning in Clerkenwell
You’ll get a fixed price before we start. It’s based on:
- Access, including roofs, risers and ceiling voids
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
- When the work can happen, such as evenings, overnight or weekends
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Your opening hours and when the area is out of use
- Where the site is and what kind of site it is
- Wide pictures of the system and the area around it
- Any previous report or certificate
For a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. A booked night’s work in Clerkenwell costs you no trading time; an unplanned closure does.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Why book with us
- Survey first, then a fixed quote
- Accredited under CHAS and SafeContractor, with ISO 9001
- A written report with photos after each visit
- A fixed price before any work starts
What we do, step by step
The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes half a day to a full day per unit, with large plant planned over several shifts. We fit London jobs around the building rather than the other way round, so a visit in Clerkenwell is typically out of hours.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Clear the space around the work
- Agree a time when the area can be out of use
- Tell us where we can park and unload
Ask for a quote
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
