About our AHU cleaning in New England
Our AHU cleans for sites in New England cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include air handling units with blocked filters and fan sections that haven’t been cleaned in years, on filter sections, dampers and louvres and heating and cooling coils.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

New England buildings and their air
About 46 miles out from central London, New England is part of the South East area we work across. Evening, overnight and weekend visits are all possible.
For buildings in and around New England, TR19® Air cleaning starts with an inspection.
New England is in Essex. Every kind of commercial site in New England, AHU cleaning is something we can help with. We can work out of hours so the site keeps running. We cover 644 places across Essex, from busy centres to quieter spots. There’s also a page for Chelmsford, roughly 22 miles from New England.
Our technicians cover all of the CO9 postcode area for AHU cleaning and the roads nearby. We also cover Birdbrook (1 mile south). Within a short drive, we also cover Braintree (13 miles south), Saffron Walden (11 miles west), Halstead (10 miles south-east), Great Dunmow (14 miles south-west), Great Notley (14 miles south) and Bocking (12 miles south).
Local landmarks in New England
We work in commercial kitchens and buildings around Haverhill Railway Walks. Well-known places in the area include Clare Castle (4.2 miles east) and Haverhill and District Local History Centre (2.5 miles north-west).
What happens on the day
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 one overnight shift for many single units, with bigger plant phased. Visits to a village like New England are booked in advance, at a time that suits whoever runs the site.
- 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.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
Getting ready for the visit
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids

When to call us in New England
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
It’s time to book a visit if you see:
- Intake sections clogged with outdoor debris
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Dust-coated heating and cooling coils
For sites in and around New England, the units and the ductwork are both looked at.
What your quote should include
- Whether they’re fully insured
- Proof of accreditation you can verify
- How VAT is shown on the quote
- Whether a survey comes first
What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Access, including roofs, risers and ceiling voids
- The condition of the system
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Any previous report or certificate
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
Getting a quote doesn’t take long. Send a few details and pictures, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- File each AHU report in the maintenance log
- Book the next check in line with the report
- Do not ignore odours coming through the grilles
- Keep filter changes on time and recorded
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Leave it or put it right?
A clean unit feeds cleaner air into the ductwork, so the whole system stays cleaner for longer. That makes the next inspection of a building in New England simpler. Planning a trip to New England ahead is easier for everyone than a rushed one.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

- One number for every site across the South East and London

Different parts, different methods
Filters
Clogged filters reduce airflow, and dirt can get round the edges. We clean the frames and rails so the filters sit tight.
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
New England questions
Is New England within the area you cover?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you do AHU cleaning in New England?
Yes. Our area runs across London and the South East, New England included. A fixed quote normally follows within one working day of the survey details.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How do you keep the site clean during the work?
By covering it before any work starts. The work is kept contained and clean down when we finish.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used and we will propose a schedule with a fixed quote.
Do you work evenings or weekends?
Yes, wherever it helps the building. We plan the shutdown window with you.
Are you insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
