Extract fan cleaning in Dollis Hill

Do you need extract fan cleaning in Dollis Hill?

The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.

Any of these means the system needs a check-up:

  • Thick grease on the impeller and casing
  • An extract fan with no cleaning record
  • Grease escaping from the fan outlet
  • Hot, greasy smells near the fan

Healthcare kitchens, like those at hospitals such as St Andrew's Hospital (about under half a mile south), often cook for long hours, which puts them in BESA’s heavier-use bands.

Before you book anyone

  • Whether they’re fully insured
  • How they set the interval to the next visit
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
  • What paperwork you get at the end

Questions to ask before booking

Extract fan cleaning for kitchens and businesses in Dollis Hill

Kitchen extract fans come in different forms: fans on the roof, fans built into the duct run, and fans on an outside wall. The way in depends on the type, and we plan that during the survey. Common call-outs are for a fan motor running hot under a coat of grease and a fan coated in grease inside its housing, across discharge points, axial fans and centrifugal fans.

In a London area like Dollis Hill, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.

The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Dollis Hill kitchens: local notes

Food Standards Agency data counts about 201 restaurants, cafés and canteens and about 156 takeaways and sandwich shops in and around Dollis Hill, up to about a mile and a half out. Grease builds up on fan blades and housings in kitchens like these, unbalancing the impeller. Environmental health officers from Brent council inspect food businesses in Dollis Hill. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London jobs usually start after the last service, with loading and roof access agreed with the building first.

Term dates shape school work: for a school like Our Lady of Grace Catholic Junior School, an extract clean fits neatly into a half-term or summer break. For kitchens close to Brent Cross West station, where the day often starts early and ends late, the extract can be cleaned overnight.

  • Centrifugal fans
  • Fan housings

  • In-line fans
  • Roof-mounted fans

How the visit works

Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Dollis Hill.

  1. First we locate the fan and agree how it’s safely isolated.
  2. With the fan isolated, the housing is opened.
  3. The impeller and the housing around it are scraped clean.
  4. We degrease the fan and housing, taking care around the motor.
  5. We reassemble, run the fan and photograph the result.

Getting ready for the visit

  • Let us know about parking and loading
  • Allow time for equipment near the work to be turned off and cool down
  • Let us know when the site is closed or quiet

Advice

Why act early in Dollis Hill

Grease on the fan is grease in the system. TR19® Grease covers the whole extract, fan included, and insurers asking for TR19 cleaning expect the full system. It’s better booked as a planned job in Dollis Hill than handled as an emergency.

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before work begins.

Why Dollis Hill businesses choose us

  • Work around your opening hours, with 24/7 emergency cover
  • Photo reports with every job
  • Ventilation hygiene specialists since 2009
  • BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease

In-house cleaning or a specialist?

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. Leave those to us.

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 will take a look and give you a fixed quote.

Dollis Hill questions

Do you work overnight in Dollis Hill?

Yes, out-of-hours work is a big part of what we do. It means the site in Dollis Hill keeps running as normal. Let us know the hours you are closed and we’ll book within them.

How do you handle parking and loading in Dollis Hill?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. If the building has a loading slot system, we’ll book into it.

Are you insured?

Yes, fully. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.

Can you look after several sites?

Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.

Can you come out in an emergency?

Yes. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line and we’ll talk you through the next steps.

Is TR19 a legal requirement?

No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.

What’s TR19?

It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.

How far ahead should we book?

Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.

Keeping the system healthy

Simple habits between visits make a real difference. Our advice:

  • Make sure the fan is included each time
  • File the fan’s report with your other records
  • Listen for new noises or vibration from the fan
  • Look for grease stains near the discharge

The area around the fan is left clean, with waste grease removed. On a roof or outside wall, we leave the surrounding area tidy.

Listen to the fan. New noise or vibration often means grease is building on the impeller and early action can save a repair.

Different parts, different methods

Roof-mounted fans

On a roof, the air is cooler and grease drops out faster. We scrape and degrease the blades and casing.

Kitchens with long cooking hours

Long cooking hours mean more grease reaches the fan. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
