AHU Cleaning in Godalming
AHU cleaning for Godalming, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Stale or musty smells from the ventilation
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
What the work involves, part by part
Rooftop and plant room units
Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
AHU cleaning in Godalming, done properly
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so the report shows exactly what was done. The work covers filter sections, internal panels and dampers and louvres, and common reasons people get in touch are coils clogged with dust and debris and drain trays holding standing water.
For a building near Godalming, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What affects the cost of AHU cleaning
Sites vary more than people expect. The main factors:
- Travel, parking and unloading
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
- How many systems or sites are involved
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
What to send for a quote
Photos let us diagnose from a distance. Try to include:
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
To help us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then call us on 0345 646 2711, or send details by email.
How the visit works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes half a day to a full day per unit, with large plant planned over several shifts. Everything the job in Godalming needs is worked out beforehand, from the survey.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Tell us where we can park and unload
- Dig out any earlier paperwork for the system
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Landlords, agents and facilities managers
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side, and the report can go to both.
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Aftercare tips
Results last longer with the right care. We suggest:
- Stick to the filter change plan
- Note any water around the unit or leaks below it
- Keep inspection doors on the unit in good order
- Do not ignore odours coming through the grilles
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
