Merrow: your questions answered
Which fire authority looks after Merrow?
Merrow is in the area of Surrey Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Who inspects food businesses in Merrow?
Kitchens in Merrow are inspected by Guildford council’s environmental health officers. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What information do you need?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and any previous paperwork make it quicker. After that, simply call 0345 646 2711 or email us.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How long will the duct clean take?
It takes a shift or more, depending on the length of the runs and the number of access points. We’ll confirm the time when we quote.
Are you insured?
Yes, we’re fully insured. We also hold CHAS and SafeContractor for clients who vet their contractors.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. We normally quote within one working day, and emergencies are covered by our 24/7 line.
How we handle ductwork cleaning in Merrow
Not every duct has enough access panels. TR19 calls for any section we couldn’t reach to be recorded, and new panels can be fitted to reach it in future. An honest report beats a guess. The work covers horizontal duct runs, bends and junctions and vertical risers, and the jobs we see most are a rancid smell from the extract duct and readings above 200 microns from a grease thickness test.
For a smaller kitchen near Merrow, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What happens if it’s left?

The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Take a look at what affects the cost and our accreditations and certificates.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We can diagnose it and quote.
Do you need ductwork cleaning in Merrow?
A vertical riser can run up several floors. Grease clings to the walls and can run down to the base, where it can pool. Panels along the riser make proper cleaning possible.
If you notice any of these, it’s worth a diagnosis:
- Duct runs with no cleaning record
- Stale grease odours from the duct
- Years of grease along the duct floor
- A grease test showing the duct is overdue
For schools such as Bushy Hill Junior School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Before booking anyone
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
- What hours they’ll be on site
- Whether inaccessible sections are listed on the report
What ductwork cleaning looks like in Merrow
The FSA’s food hygiene register includes about 8 pubs and bars within roughly a mile and a half of the centre of Merrow. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Merrow get their food hygiene inspections from Guildford council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Merrow falls to Surrey Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St. Luke’s Hospital is the nearest hospital to Merrow, about 1.5 miles south-west. If your kitchen is in a listed or historic building, like the houses around Merrow (Clandon Park is about 0.9 miles east), fitting access panels needs care.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what ductwork cleaning will not do:
- A duct that’s too small or badly routed for the kitchen (a design issue)
- Faulty fire dampers
- Sections that cannot be reached safely without new access (those are recorded, and panels can be fitted)
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.
What the work covers
- Vertical risers
- Access panels
- Attenuators

- Horizontal duct runs

Fixed quotes for ductwork cleaning in Merrow
Sites vary more than people expect. The main factors:
- Site requirements such as sign-in and permits
- The size of the system
- Whether it’s a one-off visit or part of a schedule
- Travel, parking and unloading
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
Asking for a quote
There’s no need for technical detail. It helps if you can send:
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
- The postcode and the type of business
- How we’d reach plant on a roof or in a plant room
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. Then we send a fixed price, before any work starts.

How it works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes a few hours for a short run, longer for long runs and tall risers. Visits to a place like Merrow are planned ahead, so we arrive with what the survey says the job needs.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Out of hours, the area is protected and the access panels opened.
- Thick grease is scraped out, then the runs and risers are degreased.
- We close up, re-test, photograph and record anything out of reach.
How to prepare
- Dig out any earlier paperwork for the system
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
For a fixed quote, call 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. You’ll normally have a quote within one working day.
Advice
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Never cook with a filter missing
- Have the grease measured if cooking hours go up
- Ask us about extra access panels where sections can’t be reached
- Flag drips from the duct straight away
When the duct is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. It shows when and where the clean was done and by whom.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
