TR19 Compliant Ventilation & Kitchen Extract Cleaning — Scotland-Wide
Canopy & Filter Cleaning
Extraction canopies and grease filters are the first line of defence between your cooking equipment and the ductwork above. TR19 identifies canopy plenum chambers and filters as the primary hotspots for grease accumulation — and the elements most scrutinised during a fire risk assessment or insurance survey.
Deep Clean Scotland provides dedicated canopy and filter cleaning services across Scotland, with a TR19 compliance certificate and photographic report issued on every visit. We also offer a filter laundry service and filter replacement where filters are beyond serviceable condition.
Why Canopy & Filter Cleaning Matters
The extraction canopy sits directly above your cooking equipment and captures the airborne grease, steam, and combustion products produced during every service. Over time, grease accumulates in the canopy body, the plenum chamber behind the filters, and on the filters themselves. TR19 identifies these as the primary hotspots in any kitchen extract system — and the areas most likely to be examined first by a fire risk assessor or loss adjuster following an incident.
Filters that are saturated with grease can no longer perform their function. Contaminated air — carrying grease particles — passes directly into the ductwork above, accelerating deposit build-up throughout the system. In the event of a fire, a grease-laden canopy and saturated filters provide immediate fuel and a direct path for fire to travel into the ductwork and spread through the building.
Under the Fire (Scotland) Act 2005 and the Regulatory Reform (Fire Safety) Order 2005, the Responsible Person must ensure that fire precautions are maintained — and this explicitly includes the extract system. Failure to maintain TR19 benchmark grease deposit levels is a breach of your legal duties and can result in invalidated fire insurance, enforcement action by the Scottish Fire and Rescue Service, and personal criminal liability.
Cleaning frequency is determined by cooking load and system classification under TR19. High-volume operations such as fast food, wok cooking, and chargrilling require more frequent cleaning than lighter-use kitchens. We assess your system at survey stage and recommend a cleaning schedule appropriate to your operation — giving you a documented, defensible compliance programme.
TR19 Recommended Cleaning Frequencies
Heavy use
Fast food, wok cooking, chargrilling, 24-hour operations
Moderate use
Pub kitchens, hotel restaurants, staff canteens
Light use
Offices, care homes, low-volume catering
Frequencies are indicative guidance based on TR19 cooking load classifications. Actual frequency is determined by system assessment.
What We Can Include
Scope is confirmed at survey stage based on your canopy type, filter specification, and system configuration.
Also considering a full kitchen deep clean?
Canopy and filter cleaning is a separate service from commercial kitchen deep cleaning. For full decarbonising and degreasing of ovens, fryers, grills, and surfaces, see our dedicated kitchen deep cleaning service.
Your Legal Obligations
Requires the Responsible Person to ensure fire precautions are in place and maintained. Extract systems — including canopies and filters — must be kept free of grease accumulation to a TR19 benchmark standard.
Applies to non-domestic premises in England and Wales and is referenced by Scottish insurers and fire risk assessors. Requires a suitable and sufficient fire risk assessment that addresses extract system maintenance.
The industry standard for ventilation hygiene. Sets benchmark grease deposit levels and cleaning frequency requirements by cooking load classification. A TR19 certificate is the recognised evidence of compliance for insurers and enforcement bodies.

Frequently Asked Questions
Why are canopies and filters the most important part of the extract system to clean?
TR19 identifies canopy plenum chambers and grease filters as the primary hotspots for grease accumulation in a kitchen extract system. Grease deposits here are the most likely ignition source in a kitchen fire. Regular cleaning of canopies and filters is the single most effective action you can take to reduce fire risk from your extract system.
How often should canopies and filters be cleaned?
Filter cleaning frequency depends on cooking type and volume. For heavy-use kitchens (e.g. busy restaurants), filters should be cleaned weekly or fortnightly. Canopy plenum chambers should be cleaned at the same frequency as your full TR19 extract clean — quarterly for heavy use, every 6 months for moderate use, and annually for light use.
What is included in a canopy and filter clean?
A full canopy and filter clean includes: deep degreasing of the canopy body, plenum chamber, and baffles; grease filter removal, laundry cleaning, and refitting; grease collection tray and drain point cleaning; fan blade and motor housing degreasing; before-and-after photographs; and a TR19 compliance certificate.
Do you offer a filter replacement service?
Yes. Where filters are beyond serviceable condition — damaged, deformed, or unable to achieve the required grease capture efficiency — we can supply and fit replacement filters. We will advise you on the condition of your filters during every visit.
Will I receive a compliance certificate after canopy cleaning?
Yes. We issue a TR19 compliance certificate and photographic report after every clean. The certificate documents the work carried out, grease levels recorded, and confirms the system meets TR19 benchmark standards. It is suitable for your insurer, fire risk assessor, or EHO.
