How we handle AHU cleaning in Forest Hill
Our AHU cleaning covers sites in Forest Hill and the rest of Greater London, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. If you have blocked condensate drains and slimy trays and plant that needs cleaning after a refit, 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. An inspection first shows where cleaning is needed in a building in Forest Hill.
A written report with photos follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What happens on the day
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes half a day to a full day per unit, with large plant planned over several shifts. Getting kit into a London building takes planning, so let us know where we can load and park in Forest Hill.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What else we do in Forest Hill
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Do you need AHU cleaning in Forest Hill?
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. So a unit can be well maintained and still dirty.
Clients typically contact us when they notice something like this:
- Coils clogged with dust and debris
- Dirty fans and fan housings
- Stale or musty smells from the ventilation
- Blocked condensate drains and slimy trays
If you run a surgery, dental practice or care home near Forest Hill, clean ventilation matters as much to you as to a hospital like Dulwich Community Hospital (about 1.5 miles north-west).
What your quote should include
- How areas they can’t reach will be recorded
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
- Whether the figure could change on the day
Why deal with it now?
Stuffy rooms and stale smells in a building in Forest Hill can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Why book with us

AHU cleaning in Forest Hill: local notes
Food Standards Agency data includes about 63 schools, colleges and universities and about 70 caring premises (care homes, nurseries and hospitals) across Forest Hill and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. Many London buildings have had their ductwork altered through several fit-outs, so an inspection comes first. Dulwich Community Hospital is the nearest hospital, about 1.5 miles north-west of Forest Hill. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you manage a school such as Fairlawn Primary School, ventilation cleaning is best booked for the holidays. If you manage offices or shops near Honor Oak Park station, their ventilation can be inspected and cleaned out of hours.
Forest Hill is about 2 miles south-east of East Dulwich, in Greater London. From the centre of Forest Hill to the outskirts, AHU cleaning is available to all kinds of commercial premises, from a single unit to a large public building. Forest Hill is one of 764 towns, villages and districts in Greater London we cover for AHU cleaning.
AHU cleaning in SE23, SE22 and SE26 follows the same survey, fixed quote and written report as everywhere else we cover.

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
How we price AHU cleaning
We do not publish a price list, because no two systems are the same. The quote depends on:
- Site requirements such as sign-in and permits
- The condition we find in the survey
- When the work can happen, such as evenings, overnight or weekends
- Whether it’s a one-off visit or part of a schedule
Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before we start.
Asking for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Any access panels or hatches you can see
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
- The site address and the type of premises
Quotes are quick. Send a few details and pictures, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Your questions about AHU cleaning in Forest Hill
What do you need to know about parking in Forest Hill?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Can you clean school ventilation in Forest Hill during the holidays?
Yes, and it’s the easiest time to do it. With about 63 schools and colleges on the FSA’s register within roughly a mile and a half of Forest Hill, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Do you survey before quoting?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
What types of premises do you cover?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
How do you protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you offer emergency callouts?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
What happens if you cannot reach some of it?
Anything we cannot reach goes on the report, with a note of where it is, and we tell you what would make it reachable, such as extra access panels in ductwork.
