What affects the cost of extract fan cleaning

Every site gets its own quote. This is what makes a difference:

  • Site requirements such as sign-in and permits
  • How easy every part is to reach
  • How many systems or sites are involved
  • Whether it’s a one-off visit or part of a schedule

Working hours, access and the scale of the site all affect the cost. We take each of them into account and give you a fixed price before work begins.

What to send for a quote

To speed up the quote, please include:

  • The site address and the type of premises
  • Any symptoms, from odd noises to smells or leaks
  • The paperwork from the last visit, if you have it
  • Wide pictures of the system and the area around it

Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

About our extract fan cleaning in Crossness

If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. Common call-outs are for a fan that has never been cleaned and grease stains around the discharge, on roof-mounted fans, discharge points and fan housings.

In a London area like Crossness, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, so a regular TR19® clean protects everyone in it.

Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

What happens if it’s left?

Without a working extract fan, a kitchen cannot cook safely. Many fan problems start with grease, so cleaning the fan helps keep it working. If it does fail, our 24/7 emergency line is there. In a London building, a problem in a duct, damper or fan rarely stays in one unit.

Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

Why Crossness businesses choose us

  • A written report with photos after every visit
  • Evenings, overnight and weekends, plus 24/7 emergency callout
  • A single point of contact for sites across the South East and London
  • Every job surveyed first

Multi-site and managed buildings

We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.

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 your team can do, and what needs us

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.

Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

The process

Everything the job needs comes with us, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes a couple of hours per fan, depending on its size and the build-up. Expect the work in Crossness to happen after your last customer leaves, not during trading.

  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. We clean the casing, the outlet and around the motor.
  5. We run the fan and note its condition in the photo report.

How to prepare

  • Mention any parking or loading restrictions
  • Move anything stored near the system
  • Allow time for equipment near the work to be turned off and cool down

Aftercare tips

How long the results last depends on use and care. Here’s what we suggest:

  • Keep the grease filters clean and in place
  • Make sure the fan is included each time
  • Leave a clear route to the fan
  • Tell us if the extract feels weaker

A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.

Fewer grease particles reaching the fan means less build-up. Keep the grease filters clean, fitted and in place, and replace any that are damaged.

Crossness kitchens: local notes

Look up Crossness on the FSA’s food hygiene register and you’ll find about 44 restaurants, cafés and canteens and about 33 takeaways in and around Crossness, up to about a mile and a half out. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Most London extract cleaning happens at night, after the last service. It’s Bexley council that sends environmental health officers to food businesses in Crossness. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.

Bursars and site managers at schools such as St John Fisher Catholic Primary School tend to book extract cleaning for when the kitchen is empty. A hospital like Erith and District Hospital, about 2.1 miles south-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. If you run a church or community hall kitchen, near Church of the Cross or elsewhere in Crossness, its extract still collects grease from every lunch and event.

Crossness is about 2 miles north-west of Erith, in Greater London. Crossness gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with pictures. We cover 764 places across Greater London, large and small. Our London page covers sites nearby (10 miles or so).

Common questions in Crossness

How do you handle parking and loading in Crossness?

Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.

Who would carry out a food hygiene inspection at a kitchen in Crossness?

Kitchens in Crossness are inspected by Bexley council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.

What accreditations do you have?

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.

How often should the extract fan be cleaned?

It depends on how many hours the kitchen cooks, under BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.

What do you need from me for a quote?

Only a few details: 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 us on 0345 646 2711, or send details by email.

What is TR19?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

Why has my extract fan got louder?

Build-up on the impeller is a frequent reason, because it unbalances the fan. It can also be wear in the bearings or motor, which our report will flag.

Can the fan be cleaned between full cleans?

Yes, where it makes sense. We will often suggest checking the duct too, as a greasy fan usually means a greasy duct, but the choice is yours.

What a clean will not put right

We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

  • An undersized fan that can’t cope
  • A motor that has burnt out
  • Electrical faults in the fan’s supply or controls (an electrician’s job)

If you are not sure, just phone us on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
