AHU cleaning for kitchens and businesses in Fitzrovia
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. If you have dirty coils holding back the airflow and units that have only ever had filter changes, we can help.
London buildings tend to keep their plant on the roof or below ground, so work in Fitzrovia is often done in the evening or at weekends. Loading and parking are planned with the building first.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
AHU cleaning around Fitzrovia
The FSA’s food hygiene register lists about 73 schools, colleges and universities, about 51 care, childcare and hospital premises and about 232 hotels and B&Bs with registered kitchens or food service in and around Fitzrovia, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. The nearest hospital to Fitzrovia is London Foot Hospital, about less than half a mile south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For workplaces around London Euston station with mechanical ventilation, cleaning can be done in the evening or at weekends. Healthcare ventilation, from large hospitals like London Foot Hospital (about less than half a mile south-west) to small clinics, depends on clean filters, coils and ducts. Wherever a school like All Souls CofE Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Fitzrovia: your questions answered
Is parking a problem for work in Fitzrovia?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Night visits tend to make loading easier on London streets.
Do you clean school ventilation in Fitzrovia in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 73 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Fitzrovia. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
What information do you need?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call 0345 646 2711 or drop us a line.
Will you repair the fan or motor?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How much does AHU cleaning cost?
We don’t publish prices, because the cost depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.

Why it’s worth doing now in Fitzrovia
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. London sites work long hours, and the longer a job is left, the bigger it gets.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.
Why choose Duct Doctor in Fitzrovia
- A fixed price before any work starts
- Work around your opening hours, with 24/7 emergency cover
- Each visit written up, with photos
- We diagnose before we treat
Take a look at what affects the cost or our accreditations and certificates.
Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Managing agents and facilities teams in Fitzrovia
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. From there, it takes from a few hours for a compact unit to a day or more for a large one. Getting kit into a London building takes planning, so let us know where we can load and park in Fitzrovia.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Let us know how we reach the system, including roofs, risers and plant rooms
- Agree a time when the area can be out of use
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
Advice
How we price AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- One-off work versus a regular cycle
- How big the system is
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. Ask for a fixed quote and we’ll go through it with you.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- The times we could work without disrupting the site
- Any symptoms, from odd noises to smells or leaks
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.
When it’s something else
Some problems need a different service or another trade:
- Building management system faults
- Breakdowns that need a mechanical engineer
- Dirty ducts beyond the unit itself
Not sure which it is? You can ring 0345 646 2711, or email photos and we’ll tell you honestly.
