Great Easton questions
Do you offer AHU cleaning in Great Easton?
Yes, Great Easton is within the area we cover across London and the South East. You can call us on 0345 646 2711 or drop us a line and tell us what needs doing.
Can you come to Great Easton after we close?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. The survey shows whether the ducts need cleaning now.
Can you price the work without visiting?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
AHU cleaning in Great Easton, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers internal panels, supply and extract fans and drain trays, and the jobs we see most are dirty filters cutting the airflow and drain trays holding standing water.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes one overnight shift for many single units, with bigger plant phased. Visits to a village like Great Easton are booked in advance, at a time that suits whoever runs the site.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
How to prepare
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
- Mention any parking or loading restrictions
Getting a quote
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then call us on 0345 646 2711 or drop us a line.

When something else is needed
AHU cleaning cannot fix everything, and we’d rather say so up front. It does not solve:
- Dirty ducts beyond the unit itself
- A system that’s undersized for the building
- Damaged coils beyond cleaning
If in doubt, call us on 0345 646 2711 or use the quote form and we’ll say what we think.
Where we work
- Filter sections
- Dampers and louvres
- Drain trays
- Internal panels
- Supply and extract fans
- Heating and cooling coils
What the work involves, part by part
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. We clean the impeller, housing and surrounding section.
Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards, and check every one is shut.
For landlords and multi-site operators
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
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 are happy to quote for all of it.
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Report water on the plant room floor
- Check the drain tray is emptying during routine visits
- Do not store bins or materials near the intake
- Flag stale or damp smells in the supply air
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
How we price AHU cleaning
The survey tells us what the work involves. The main factors are:
- The times the site is available
- How big the system is
- Travel, parking and unloading
- Any permits to work or inductions
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before we start.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- The roof, plant room or outside wall the system runs to
- 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.
Do you need AHU cleaning in Great Easton?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For anyone working, learning or staying in a building in Great Easton, that is air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Condensate trays that won’t empty
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
- Dirty coils holding back the airflow
In Great Easton, we look inside the system before deciding what needs cleaning.
