Extract fan cleaning across Box Hill

How it works

On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes an hour or two for one fan, longer when it’s hard to reach. A few photos of the system help us make the most of a visit to a place like Box Hill.

  1. First we check the fan’s condition and how it sounds.
  2. Once isolated, we open the fan up.
  3. The impeller is cleaned blade by blade so it runs balanced.
  4. Housing, outlet and the area around the motor are cleaned.
  5. We run the fan and note its condition in the photo report.

Getting ready for the visit

  • Mention any sign-in, permit or induction we need
  • Mention any parking or loading restrictions
  • Arrange a key holder or contact on site

Extract fan cleaning in Box Hill

Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you have rough running from the extract fan and a fan that has never been cleaned, we can help.

Work in a small place like Box Hill starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

Think of the report as the system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

Part by part

Roof-mounted fans

A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.

Inline duct fans

Space around an inline fan can be tight, so the method is planned in advance. If it cannot be reached fully, the report says so.

Box Hill questions

Can school kitchens in Box Hill be cleaned in the holidays?

Yes, and it’s the easiest time to do it. Around Box Hill, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Just ring 0345 646 2711 or use the quote form with your term dates and we will plan around them.

Do you cover smaller places like Box Hill?

Yes, we work in villages as well as towns, and Box Hill is covered. Just mention lanes, gates or anything else about the site when you book.

Does a TR19 kitchen extract clean cover the fan?

Yes. A TR19 Grease clean covers everything from canopy to discharge, and the fan sits right in that path, so it’s cleaned too.

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.

Do you have insurance?

Yes. We carry full insurance, and we’ve been trading since 2009.

Can you clean the fan on its own?

Yes, a fan can be cleaned on its own. That helps when the fan needs attention before the next full clean, but it does not replace a full TR19 clean.

Is there a survey before the work?

Yes, every time. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.

What if parts of the system cannot be reached?

We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.

When to call us in Box Hill

Fans that are hard to reach are often the ones that get missed. A fan that has never been cleaned can be heavily coated, and the report will show it.

These are the problems we see most often:

  • A smell of hot grease from the extract
  • A fan coated in grease inside its housing
  • Grease around the motor and its mounts
  • Less air being pulled from the kitchen

A hall kitchen that only cooks for events, whether near St. Andrew's Church or elsewhere in Box Hill, still needs its extract cleaned, just less often.

What your quote should include

  • If they look at the system before pricing
  • Whether a written report and pictures are included
  • Whether the whole system is included, or only the parts that are easy to reach
  • Whether they recommend a next date

Questions to ask before you book

What affects the cost of extract fan cleaning

Sites vary more than people expect. The main factors:

  • The size of the system
  • Working hours and out-of-hours timing
  • Any permits to work or inductions
  • Travel, parking and unloading

Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.

What to send for a quote

There’s no need for technical detail. It helps if you can send:

  • Your opening hours and when the area is out of use
  • How we’d reach plant on a roof or in a plant room
  • The postcode and the type of business
  • The paperwork from the last visit, if you have it

Want a quote for extract fan cleaning? Please ring 0345 646 2711, or send details by email with a few details about the site. We’ll talk you through the work and give you a fixed quote before anything is booked.

Landlords, agents and facilities managers

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.

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.

Why deal with it now?

Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Systems in rural buildings are often out of sight and out of mind.

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

Why book with us

  • CHAS, SafeContractor and ISO 9001
  • We are fully insured
  • Trading since 2009
  • Every job surveyed first

Kitchen extracts in Box Hill

Food Standards Agency records list about 6 restaurants, cafés and works canteens across Box Hill and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. In Box Hill, food businesses are inspected by environmental health officers from Mole Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. Surrey Fire and Rescue Service covers Box Hill. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.

A hospital like Headley Court, about 2.8 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Commuter trade near Betchworth station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Box Hill is about 2 miles north-east of Dorking, in Surrey. Sites in Box Hill get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Our area takes in 395 places across Surrey, large and small. You can also see our page for Guildford, about 12 miles away.

Keeping the system healthy

A little care between visits keeps the system in better shape. Our advice:

  • Don’t turn the fan off mid-service
  • Never cook with a filter missing
  • Keep each photo report with the maintenance log
  • Do not store items in front of the fan’s access point

Keep the report with the maintenance log and fire risk assessment. It gives a dated record of the fan’s condition, which helps if anything changes later.

Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
