AHU cleaning for kitchens and businesses in Wethersfield
Our AHU cleans for sites in Wethersfield cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. Every clean comes with a TR19® certificate and before and after photos in a report. If you have coils clogged with dust and debris and dust built up on fan impellers, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The sign-off is always in writing: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

What else we do in Wethersfield
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.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
Ventilation in Wethersfield buildings
Going by the FSA’s register, there are about 3 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) serving food in Wethersfield and the streets around it, up to about 1.5 miles out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Wethersfield is Braintree Community Hospital, about 5.5 miles south-east. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. We cover Wethersfield, about 40 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.
Healthcare buildings such as Braintree Community Hospital, about 5.5 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near Wethersfield, yours matters too.

What we’re called out for in Wethersfield
Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.
Any of these means the system needs a check-up:
- Intake sections clogged with outdoor debris
- Blocked condensate drains and slimy trays
- Air handling units never cleaned inside
- Dirty filters cutting the airflow
Ventilation work in and around Wethersfield is risk-based: inspect, then clean what needs it.
What to look for in a quote
- Exactly which parts of the system are covered
- Proof of insurance
- Whether the quote shows VAT
- When they can work, and whether that’s outside your opening hours
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Report water on the plant room floor
- Flag stale or damp smells in the supply air
- Look at the condensate drain whenever the unit is serviced
- Report stiff or damaged access doors
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
- The condition we find in the survey
- Access, including roofs, risers and ceiling voids
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
When you contact us, these details help:
- The paperwork from the last visit, if you have it
- A few general shots of the system
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before work begins.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Your questions about AHU cleaning in Wethersfield
Can a school’s ventilation in Wethersfield be done out of term time?
Yes. The holidays are the usual time for school work. Around Wethersfield, the Food Standards Agency lists about 3 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Can you come to Wethersfield after we close?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Wethersfield needn’t be disturbed. Just phone us on 0345 646 2711, or send details by email with your opening times and we will plan around them.
Where does the waste go?
Waste is contained during the work and removed when we leave, including grease, debris and dirty water. None of it is left on site.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What’s TR19?
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, and TR19® Air covers general supply and extract systems.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What we do, step by step
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, clear away and leave you the report. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Wethersfield.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Mention any parking or loading restrictions
- Find the previous report, if there is one
- Tell us the best time to work, such as after service or at a weekend
