How we handle AHU cleaning in Hatfield Broad Oak
All the building’s air passes through the fan, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers supply and extract fans, internal panels and dampers and louvres, and the jobs we see most are leaves and litter drawn into the unit and plant that needs cleaning after a refit.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How we price AHU cleaning
The price is fixed before any work begins. It’s based on:
- Site rules, permits and inductions
- Parking and loading at the site
- Working hours and out-of-hours timing
- The size of the system
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 are unsure, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.
Helping us quote
When you contact us, these details help:
- The postcode and the type of business
- Any symptoms, from odd noises to smells or leaks
- Wide pictures of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
If you need AHU cleaning in Hatfield Broad Oak, phone us on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus photos or the previous report if they’re to hand. We typically send a fixed quote within one working day.
Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Book the next check in line with the report
- Don’t store bins or materials near the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
Questions from Hatfield Broad Oak
Do you cover Hatfield Broad Oak for AHU cleaning?
Yes. Our area runs across London and the South East, Hatfield Broad Oak included. You can call 0345 646 2711 or send us an email and tell us what needs doing.
Is Hatfield Broad Oak within the area you cover?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Which sectors do you work in?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What do you need from me for a quote?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. Then call 0345 646 2711 or drop us a line.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after pictures. Keep them in the maintenance log.
How much does AHU cleaning cost in Hatfield Broad Oak?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we’ll normally reply within one working day.
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 carry full insurance.
In-house cleaning or a specialist?
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.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
How the job changes from site to site
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Why it’s worth doing now in Hatfield Broad Oak
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. A planned visit to Hatfield Broad Oak is easier to arrange than an emergency callout.
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.

What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Hatfield Broad Oak before we set off.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- 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.
Before we arrive
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Mention any locked doors, roof access or ceiling voids
How to get a quote
There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then send you a fixed quote. To get going, phone us on 0345 646 2711 or email us.
