Book kitchen extract cleaning in Blackthorn

Leave it or put it right?

If there’s a fire and the extract hasn’t been cleaned, the paperwork becomes the problem. Many policies require cleaning to TR19, and an insurer can refuse or reduce a claim without proof. A current certificate is far easier to produce than an explanation. It’s worth booking a check, because nobody sees inside a duct day to day.

What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before any work starts, so you know where you stand.

What you get with us

  • In business since 2009
  • Work around your opening hours, with 24/7 emergency cover
  • Fixed quotes, normally within one working day
  • One number for every site across the South East and London

Commercial kitchen extraction cleaning in Blackthorn

Duct Doctor has been cleaning kitchen extract systems since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. We’re often asked to deal with poor airflow at the canopy and a kitchen taken over without any extract records, across vertical risers, extract fans and plenums and filters. Kitchen extract cleaning, TR19 cleaning, extraction cleaning: whatever you call it, in Blackthorn it means the same thing to us: the whole system, cleaned and certificated.

Kitchens that fry and grill hardest need the most frequent cleans, so the interval is set by what you cook as well as how long.

Somewhere as small as Blackthorn, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.

It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. After that, the work takes as long as the system needs, from a few hours to several planned visits. A few photos of the system help us make the most of a visit to a place like Blackthorn.

  1. You send pictures or we visit, and the system is surveyed from canopy to discharge.
  2. Grease thickness is measured and the price is fixed before work starts.
  3. On the night, the equipment is off and cool and the kitchen is sheeted.
  4. We work through the system from the canopy to the fan and discharge.
  5. Readings are repeated, pictures taken, and your TR19 certificate and photo report issued.

Before we arrive

  • Dig out any earlier paperwork for the system
  • Tell us the best time to work, such as after service or at a weekend
  • Arrange a key holder or contact on site

Advice

Kitchen extract cleaning in Blackthorn: the local picture

The FSA’s food hygiene register shows about 3 cafés, restaurants and staff canteens in Blackthorn and the streets around it, up to about 1.5 miles out. Each one that cooks under a canopy has an extract system that collects grease and needs regular cleaning. Food hygiene inspections in Blackthorn are the job of Cherwell council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Oxfordshire Fire and Rescue Service covers Blackthorn. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.

Historic houses near Blackthorn, such as Boarstall Tower about 3.3 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Healthcare kitchens, like those at hospitals such as Bicester Community Hospital (about 3.1 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Different parts, different methods

Schools, hospitals and care homes

Even a kitchen that cooks only a few hours a day needs cleaning at least every 12 months under BESA guidance. Holidays make it simple to schedule.

Canopy and plenum

The canopy catches the vapour, and the plenum behind the filters is where it first condenses. We clean both inside and out, including the filter housing.

Multi-site and managed buildings

If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.

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.

Common questions in Blackthorn

Which fire service covers Blackthorn?

It’s Oxfordshire Fire and Rescue Service, which covers Blackthorn. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.

Is Blackthorn within the area you cover?

Yes, we work in villages as well as towns, and Blackthorn is covered. The journey is planned ahead, so a few details about the route help.

How often should a kitchen extract be cleaned?

The minimum is set by BESA guidance on daily use, from 3-monthly to 12-monthly. Heavy frying and grilling can mean shorter intervals, which grease thickness testing will show.

What do I get after the clean?

You get both a certificate and a photo report. They belong in the maintenance log, ready for your insurer or an inspection.

How long does a kitchen extract clean take?

Allow a single shift for most kitchens, with long duct runs and tall risers needing more time. The survey tells us how long your system will need.

Is TR19 a legal requirement?

No law names TR19 directly, but the responsible person still has a legal duty under the Fire Safety Order 2005. TR19 is the standard insurers and fire officers expect, and many policies require it.

Do you look at the system first?

Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.

What does a TR19 kitchen extract clean include?

A TR19 Grease clean covers the full extract route, not just the canopy. Canopy, plenum, filters, ductwork, risers, fan and discharge are all included, reached through access panels where needed.

Fixed quotes for kitchen extract cleaning in Blackthorn

A fixed price needs a few facts first. We check:

  • What state the system is in
  • A single visit or a regular plan
  • The scale of the work
  • How many systems or sites are involved

Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

What to send for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Wide photos of the system and the area around it
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The times we could work without disrupting the site
  • Where the site is and what kind of site it is

Quotes are quick. Call or email with a few details and you will usually have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

What staff can safely do

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.

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, next to our reports.

Signs you need kitchen extract cleaning in Blackthorn

What’s on the menu matters as much as how much is cooked. Frying, grilling and roasting send far more fat into the canopy than steaming or boiling, which is why grease readings matter more than the calendar.

Signs it’s time to call us include:

  • Stale cooking odours from the system
  • Grease drips onto cooking equipment
  • Missing paperwork after a change of operator
  • An overdue clean flagged by an EHO or fire officer

School kitchens, at schools like Five Acres Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Questions to ask before you book

  • What happens if part of the system cannot be accessed
  • Proof of insurance
  • When the next visit should be, and why
  • When they can work, and whether that’s outside your opening hours
