About our AHU cleaning in Bayford
Units vary a lot in size, age and layout, whether it’s a compact unit in a ceiling void or a big unit on the roof. We look at the unit first, from pictures or a site visit, and give you a fixed quote before any cleaning starts. We are often asked to deal with dirty filters cutting the airflow and plant that has been serviced but not cleaned, on filter sections, internal panels and supply and extract fans.
Somewhere as small as Bayford, ducted ventilation is typically limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Bayford buildings and their air
About 2.6 miles north of Bayford is Hertford County Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. Bayford is about 18 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
If you manage shops or offices close to Bayford station, a TR19® Air inspection shows whether the ductwork needs cleaning. Healthcare buildings such as Hertford County Hospital, about 2.6 miles north, depend on their ventilation; if you manage a surgery, clinic or care home near Bayford, yours matters too. Wherever a school like Richard Hale School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Honest limits

- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
If in doubt, phone us on 0345 646 2711, or send details by email and we will say what we think.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. A few tips:
- Book the next check in line with the report
- Report musty smells from the vents right away
- Keep filter changes on time and recorded
- Check the drain tray is emptying during routine visits
Stick to the filter change schedule, as that does more than anything to keep the unit clean. Log every change so it’s easy to see when the next is due.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
Leave it or put it right?
Stuffy rooms and stale smells in a building in Bayford can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. It’s simpler to plan the work at Bayford now than to arrange it in a hurry later.
When the work has to happen, how we reach it and how big the site is can all change the price. Each of those is built into the quote, and the price is fixed before any work starts.

Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.

What else we do in Bayford
How the visit works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and leave you the report. The visit itself takes one overnight shift for many single units, with bigger plant phased. Somewhere like Bayford, lanes, gates and parking are worth mentioning in advance.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Let us know when the site is closed or quiet
- Tell us where we can park and unload
- Let us know how we reach the system, including roofs, risers and plant rooms

Questions from Bayford
Is Bayford in your area for AHU cleaning?
Yes, Bayford is covered. A fixed quote usually follows within one working day of the survey details.
Do you work in villages like Bayford?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you give a certificate after the clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
How long does it take to clean an air handling unit?
It takes a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and we will confirm the time when we quote.
Do you look at the system first?
Yes. We always survey first, from your pictures and details, or with a visit where necessary. A fixed quote follows.
When should our AHU next be cleaned?
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.
What does AHU cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. We fix the price before work begins.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Whether we need access equipment or extra panels
- The number of sites or systems
- How big the system is
- Parking and loading at the site
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before we start.
Asking for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any previous report or certificate
- The site address and the type of premises
- Your opening hours and when the area is out of use
- A few general shots of the system
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then phone us on 0345 646 2711, or send details by email.
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
