What affects the quote in Roydon Hamlet
Before we fix a price, we need to know a few things. We check:
- When the work can happen, such as evenings, overnight or weekends
- How easy every part is to reach
- The scale of the work
- A single visit or a regular plan
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re not sure what’s needed, call us on 0345 646 2711, or email photos for straight advice and a fixed quote.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Any previous report or certificate
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For a fixed quote, phone us on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.
AHU cleaning in Roydon Hamlet, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. The work covers internal panels, supply and extract fans and heating and cooling coils, and common reasons people get in touch are rooms that smell stuffy when the system runs and dirty filters cutting the airflow.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Questions from Roydon Hamlet
Do you work at weekends in Roydon Hamlet?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Roydon Hamlet needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is Roydon Hamlet within the area you cover?
Yes, we work in villages as well as towns, and Roydon Hamlet is covered. Let us know about access, parking and anything unusual about getting there when you book.
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 do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Will you repair the fan or motor?
Our AHU work is cleaning rather than mechanical repair. If we spot a fault, we note it in the report for your maintenance team to follow up.
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
For landlords and multi-site operators
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.
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.
What we are called out for in Roydon Hamlet
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Common reasons sites call us include:
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Coils clogged with dust and debris
- Units needing a clean before a new tenant or handover
School buildings such as Roydon Primary School are typically done in the holidays, so classrooms aren’t disturbed.
What to look for in a quote
- What insurance they carry
- Whether the quote shows VAT
- Whether they recommend a next date
- Exactly which parts of the system are covered
How the visit works
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Photos of the system and how to reach it help us plan a visit to Roydon Hamlet.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Find the previous report, if there is one
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Different parts, different methods
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. Somewhere as small as Roydon Hamlet, losing a kitchen or building to a fault is felt by everyone who uses it.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
