About our AHU cleaning in Fawley Bottom
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. We clean coils with methods suited to their condition, taking care not to damage the fins. If you’re dealing with plant that needs cleaning after a refit and air handling units never cleaned inside, we can help.
In a village or hamlet like Fawley Bottom, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Fawley Bottom: your questions answered
Can the work in Fawley Bottom be done at night or at weekends?
Yes. We work evenings, overnight and at weekends. That way a site in Fawley Bottom doesn’t have to lose a day’s trading. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Is AHU cleaning available in Fawley Bottom?
Yes. We work across London and the South East, and Fawley Bottom is part of that. A fixed quote usually follows within one working day of the survey details.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will typically reply within one working day.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Can you look after several sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. The survey confirms what’s in your unit before we quote.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.

From a single site to a large estate, the standard is the same: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- Site rules, permits and inductions
- How big the system is
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
Asking for a quote
What to send for a quote:
- Where the site is and what kind of site it is
- Any previous report or certificate
- When the site is open and when it’s quiet
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Part by part
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated with your site team.
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Staff cleaning versus specialist work
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.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Note any water around the unit or leaks below it
- Clear leaves and litter away from the intake
- Make sure the unit’s access doors open easily
- Keep filter changes on time and recorded
Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes from a few hours for a compact unit to a day or more for a large one. The timing of a visit to Fawley Bottom is set by you, and the travel is our side of the planning.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
How to prepare
- Agree a time when the area can be out of use
- Clear loose items from the work area
- Let us know about permits to work or site inductions
