About our AHU cleaning in Kings Cross
Our AHU cleans for sites in Kings Cross cover the parts that collect dirt: 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. Typical jobs include air handling units due a clean after building work and coils clogged with dust and debris, across filter sections, drain trays and heating and cooling coils.
Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. For a building in Kings Cross, dust settles in the units and ducts year after year.
A written report with photos follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Kings Cross
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 Kings Cross, that’s air they breathe for hours at a time.
These are the problems we see most often:
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
- Fan sections that haven’t been cleaned in years
- Drain trays holding standing water
Hospitals such as Royal National Throat (about less than half a mile east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Kings Cross are no different.
Before you book anyone
- What’s included in the scope, part by part
- Whether a written report and pictures are included
- If the quote is a fixed price or an estimate
- Whether VAT is included
When it’s something else
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Airflow problems caused by the system’s design
- The supply and extract ducts, quoted separately
- Coils that are corroded or leaking and need replacing
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer.

- Supply and extract fans
- Dampers and louvres
- Drain trays
- Heating and cooling coils
- Filter sections
- Internal panels
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Rooftop and plant room units
Units outside are exposed to weather and windblown debris. The intake section gets particular attention.
Leave it or put it right?
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.

Kings Cross: your questions answered
How do you handle parking and loading in Kings Cross?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit typically gets round them.
Can you clean school ventilation in Kings Cross during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 81 schools and colleges on the FSA’s register within roughly a mile and a half of Kings Cross, it pays to plan holiday dates ahead. Just call us on 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Do you work in Kings Cross?
Yes. Kings Cross is part of the area we cover, as part of our area across London and the South East.
Are you fully insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
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.
Can you clean the ducts connected to the AHU?
Yes, the ductwork, grilles and diffusers the unit serves. We will tell you after the survey whether the ducts need it.
Do you have a 24/7 line?
Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we will talk you through the next steps.
Do you survey before quoting?
Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. A fixed quote follows.
What affects the quote in Kings Cross
You’ll get a fixed price before work begins. It’s based on:
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- Parking and loading at the site
- Site rules, permits and inductions
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
We can often survey from pictures. The most useful are:
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- The roof, plant room or outside wall the system runs to
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.
