AHU cleaning for sites in Twyford

About our AHU cleaning in Twyford

Our AHU cleans for sites in Twyford 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. The work covers internal panels, drain trays and supply and extract fans, and people most often call us about air handling units never cleaned inside and units needing a clean before a new tenant or handover.

Somewhere as small as Twyford, ducted ventilation is normally 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.

We have been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

What affects the cost of AHU cleaning

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

  • How easy every part is to reach
  • Any permits to work or inductions
  • The condition of the system
  • The times the site is available

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

Helping us quote

What to send for a quote:

  • Your last certificate, test record or report
  • Detail shots of panels, filters and grilles
  • Problems your staff have spotted
  • Your opening hours and when the area is out of use

There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, call 0345 646 2711 or email us.

FAQs for Twyford

Do you offer AHU cleaning in Twyford?

Yes. Our area runs across London and the South East, Twyford included. Just call us on 0345 646 2711 or drop us a line with a few details of the site.

Can you come to Twyford after we close?

Yes. We work evenings, overnight and at weekends. The work in Twyford can fit around your hours. Your opening times are the first thing we ask for.

Do you clean the ductwork as well?

Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.

What does AHU cleaning cost?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.

What do you do with what you remove?

We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.

Do you have insurance?

Yes. Full insurance covers our work, and we have been trading since 2009.

Which kinds of sites do you work on?

We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.

How long will the unit be out of action?

Cleaning takes one overnight shift for many single units, with bigger plant phased. Large plant can be split over several shifts, and you can ring 0345 646 2711 or send us an email to plan it.

Do you need AHU cleaning in Twyford?

An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.

Most sites get in touch when they notice one of these:

  • Air handling units with blocked filters
  • Dust-coated heating and cooling coils
  • Air handling units due a clean after building work
  • Odours coming through the supply air

Hospitals such as Buckingham Community Hospital (about 5.3 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Twyford are no different.

How the visit works

There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Twyford is set by you, and the travel is our side of the planning.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Before we arrive

  • Make sure equipment near the work can be switched off and left to cool
  • Let us know how we reach the system, including roofs, risers and plant rooms
  • Agree a time when the area can be out of use

Ask for a quote

Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Once you have those, ring 0345 646 2711 or drop us a line.

Related advice

Between visits

To keep the system working properly between visits:

  • Check the drain tray is emptying during routine visits
  • Stick to the filter change plan
  • Don’t ignore odours coming through the grilles
  • Clear leaves and litter away from the intake

The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

Managing agents and facilities teams in Twyford

Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Staff cleaning versus specialist work

Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.

A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
