How we handle AHU cleaning in Bishopstoke
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. Typical jobs include filters that are clogged or overdue and leaves and litter drawn into the unit, on dampers and louvres, internal panels and drain trays.
Around a place like Bishopstoke, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
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, trading since 2009.

Honest limits
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
- Airflow problems caused by the system’s design

Common questions in Bishopstoke
Can you get to a site in Bishopstoke?
Yes, we work in villages as well as towns, and Bishopstoke is covered. Just mention lanes, gates or anything else about the site when you book.
Can you clean school ventilation in Bishopstoke during the holidays?
Yes, holiday work suits schools best. There are about 7 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Bishopstoke. You can phone us on 0345 646 2711 or send us an email with the dates the site is empty.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
What accreditations do you have?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
Leave it or put it right?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. A site near Bishopstoke that has to close at short notice is hard to cover for.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before we start.
Why us?
- One number for every site across the South East and London
- A written report with photos after each visit

Keeping the system healthy
After the visit, a few habits help the work last:
- Do not store bins or materials near the intake
- Diary the inspection date recommended in the report
- Look at the condensate drain whenever the unit is serviced
- Do not ignore odours coming through the grilles
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
How we price AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Site requirements such as sign-in and permits
- How big the system is
- How many systems or sites are involved
- One-off work versus a regular cycle
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.
Asking for a quote
There’s no need for technical detail. Just send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your opening hours and when the area is out of use
- Your last certificate, test record or report
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
The process
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. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Your opening hours decide when we come to Bishopstoke, not ours.
- 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.
- After photos are taken and the certificate issued.
Before we arrive
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711, or send details by email.

For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.

Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
