Fixed quotes for AHU cleaning in Shortheath
You’ll get a fixed price before work begins. It’s based on:
- The condition of the system
- How big the system is
- The number of sites or systems
- Whether we need access equipment or extra panels
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The paperwork from the last visit, if you have it
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
If you need AHU cleaning in Shortheath, call us on 0345 646 2711, or send details by email. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. We usually send a fixed quote within one working day.
AHU cleaning in Shortheath, done properly
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. Every job starts with a survey, from photos or on site, followed by a fixed quote before any cleaning starts. Typical jobs include air handling units due a clean after building work and dirty filters cutting the airflow, on drain trays, filter sections and dampers and louvres.
Work in a small place like Shortheath starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Shortheath: your questions answered
Will you come out to Shortheath?
Yes, Shortheath is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Do you work at weekends in Shortheath?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Are you accredited?
Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Are you insured?
Yes. We carry full insurance and have been trading since 2009.
Can you quote from photos?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and a fixed quote typically follows within one working day. Some sites still need a visit, and we will say so.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. Then you get a fixed quote.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Different parts, different methods
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with pictures so you can decide on any repairs.
Landlords, agents and facilities managers
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’re happy to quote for all of it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

Between visits
A little care between visits keeps the system in better shape. We recommend:
- Keep inspection doors on the unit in good order
- Change filters on schedule and log each change
- Do not ignore odours coming through the grilles
- Keep the certificate and photo report with the plant records
The ducts served by the unit may need attention too. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
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, next to our reports.
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool first, and floors and nearby surfaces are sheeted. The work itself takes half a day to a full day per unit, with large plant planned over several shifts. For a village or hamlet like Shortheath, tell us about narrow lanes, gates and parking when you book.
- We start with a survey of the unit and a fixed quote for the work.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions
- Arrange a key holder or contact on site

Why it’s worth doing now in Shortheath
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Shortheath simpler. It’s worth booking a check, because nobody sees inside a duct day to day.
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all make a difference.
