How the job changes from site to site
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
About our AHU cleaning in Gun Hill
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. We’re often asked to deal with air handling units due a clean after building work and dust-coated heating and cooling coils, across drain trays, filter sections and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Ventilation in Gun Hill buildings
Food Standards Agency data includes about 4 hospitals, care homes and childcare premises across Gun Hill and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Hellingly Hospital Railway is the nearest hospital, about 2.1 miles south-east of Gun Hill. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. We cover Gun Hill, about 43 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.

What else we do in Gun Hill
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Clear leaves and litter away from the intake
- Keep filter changes on time and recorded
- Make sure the unit’s access doors open easily
- Don’t ignore odours coming through the grilles
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Fixed quotes for AHU cleaning in Gun Hill
We don’t publish a price list, because no two systems are the same. What we look at:
- How easy every part is to reach
- Site requirements such as sign-in and permits
- Whether several sites go on one quote
- Travel, parking and unloading
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
What to send for a quote
You don’t need the technical terms. It helps if you can send:
- Detail shots of panels, filters and grilles
- The site address and the type of premises
- When the site is open and when it’s quiet
- Your last certificate, test record or report
Want a quote for AHU cleaning? Please ring 0345 646 2711 or send us an email with a few details about the site. We will talk you through the work and send you a fixed quote before you commit to anything.
What we do, step by step
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Photos of the system and how to reach it help us plan a visit to Gun Hill.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about permits to work or site inductions
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
Why it’s worth doing now in Gun Hill
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. It’s worth booking a check, because nobody sees inside a duct day to day.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before we start.
