Between visits

Good habits slow the build-up between visits. Our tips:

  • Note any water around the unit or leaks below it
  • Make sure condensate is draining away
  • Book the next check in line with the report
  • Keep the area around the fresh air intake clear

Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.

Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.

AHU cleaning for kitchens and businesses in Fields End

The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you have air handling units with blocked filters and plant that needs cleaning after a refit, we can put it right.

In a village or hamlet like Fields End, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

In-house cleaning or a specialist?

Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.

If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

How the job changes from site to site

Fans and fan sections

Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.

Why it’s worth doing now in Fields End

A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Out of sight is the usual reason a rural system goes too long without attention.

Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we’ll price it together.

Why us?

  • CHAS and SafeContractor accredited, with ISO 9001
  • Ventilation hygiene specialists since 2009
  • A fixed price before any work starts
  • Out-of-hours work and a 24/7 emergency line

Yes, out-of-term visits are normal for schools. The FSA’s register shows about 12 schools and colleges with food registrations within roughly a mile and a half of Fields End. Booking early in the term gives the best choice of holiday dates.

Do you work overnight in Fields End?

What about areas you cannot get to?

They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

What do you need from me for a quote?

The site address, the type of premises and your opening hours, along with a few pictures and any previous report.

Which accreditations do you hold?

Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.

What’s TR19?

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.

Can you look after several sites?

Yes. Tell us the addresses and what each needs and we will quote them together.

What happens to the waste?

It leaves the site with us at the end of the visit. While we work, it’s kept contained to keep the area clean.

Fixed quotes for AHU cleaning in Fields End

We don’t publish a price list, because sites vary so much. The quote depends on:

  • Whether several sites go on one quote
  • A single visit or a regular plan
  • Whether we need access equipment or extra panels
  • When the work can happen, such as evenings, overnight or weekends

What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before work begins.

Asking for a quote

When you contact us, these details help:

  • The times we could work without disrupting the site
  • Detail shots of panels, filters and grilles
  • Where the site is and what kind of site it is
  • A few general shots of the system

We do not publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711, or send details by email.

The process

We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes one overnight shift for many single units, with bigger plant phased. In a small place like Fields End, the journey is planned ahead and the visit arranged around the site’s hours.

  1. First the unit is surveyed, from photos or a visit, and the scope agreed.
  2. We arrange the shutdown with your staff and sheet the area.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. Standing water and slime come out of the tray and the drain is checked.
  5. You get a TR19® certificate and a photo report.

How to prepare

  • Mention any parking or loading restrictions
  • Allow time for equipment near the work to be turned off and cool down
  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

How to get a quote

To help us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or send details by email.

Advice

Multi-site and managed buildings

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’re happy to quote for all of it.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
