EC Cleaners Network · Openings, Takeovers & Refits
A period of closure does not prove that a restaurant kitchen extraction system is clean, maintained or ready for normal cooking again.
Before reopening, check the inherited records, fan and controls, visible condition, access, replacement air and any work carried out while the premises was closed. If the menu, equipment or layout has changed, the ventilation system may also need to be reviewed against the new operation.
How long has the restaurant been closed and what changed during closure?
Send the site details, latest extract cleaning and maintenance records, planned reopening date and any refurbishment, equipment or layout changes. Include known fan, airflow, access or contamination issues where available.
Search and Submit Ltd uses your details to respond and coordinate the enquiry, including sharing relevant information with appropriate independent specialists. Read our Privacy Policy. Please omit unrelated personal or sensitive information.
What should be checked before the kitchen comes back into use?
HSE says catering ventilation is needed to remove fumes, vapours and heat and that mechanical systems should be maintained in efficient working order. It also recommends keeping records of design criteria, commissioning performance, maintenance requirements, tests and inspections.
For a closed restaurant, those records provide the starting point. They can show what was known before closure, what maintenance was due and what still needs to be verified before normal cooking restarts.
Closure pauses the cooking operation. It does not automatically reset the condition or maintenance history of the extraction system.
Pre-opening checks for a previously closed restaurant
Cleaning history
Find the last extract cleaning report and establish what system sections were included, excluded or inaccessible.
Fan operation
Check whether the fan starts, runs and performs as expected through the appropriate competent maintenance or commissioning process.
Controls and interlocks
Confirm that ventilation controls and any safety interlocks have not been altered, isolated or left unresolved during closure.
Visible contamination
Look for obvious grease, leakage or deterioration that suggests the system needs specialist inspection or cleaning before use.
Access
Confirm roof, riser, plant-room and duct access arrangements before contractors attend.
Replacement air
Check that air supply routes, grilles and building changes have not compromised the make-up air needed by the kitchen.
Refurbishment changes
Record any new ceiling, partition, appliance, canopy, duct, fan or supply-air work completed while the premises was closed.
Do not treat an old certificate as current condition
An older cleaning certificate can help establish history, but it describes a past attendance. The associated report should be checked for the system scope, photographs, measurements, exclusions and recommended next action.
If months or years have passed, if the building has been altered, or if the fan and controls have not been maintained, the historic certificate should not be used on its own to conclude that the system is ready for reopening.
Does closure mean the system is still clean?
Not necessarily. Grease already present before closure remains unless it was removed. Inaccessible sections remain unverified unless later access was provided. Fan, motor, controls and other mechanical components can also require maintenance independently of how much the kitchen has traded.
The useful question is what condition was recorded at the last inspection or clean, what remained outstanding and what has happened to the system since.
No trading does not mean no maintenance history.
Check the fan, controls and wider ventilation system
HSE says poor maintenance is a significant cause of accidents in catering and that good maintenance helps equipment perform safely and reliably. The kitchen extract fan and its controls should therefore be considered separately from duct cleaning.
If the fan does not start, cuts out, makes unusual noise or appears to have weak pull, treat that as a technical fault rather than assuming the answer is cleaning.
What if the restaurant was refurbished while it was closed?
Refurbishment can change the ventilation system even when the fan and main duct route appear to be the same. New equipment, ceilings, partitions, door arrangements, supply-air routes or canopy positions can change airflow and capture.
If the cooking operation has changed materially, the system should be considered against the new load rather than assumed suitable because it served the previous restaurant.
Replacement air may have changed during closure
A mechanical extract system removes air from the kitchen and that air needs to be replaced. HSE says catering ventilation should provide suitable replacement air and that adequate make-up air is particularly important for gas-fired appliances.
Building work, blocked grilles, sealed openings, changed doors or altered supply systems can affect the way replacement air reaches the kitchen. Those changes may not be obvious from the extract fan alone.
Reopening should confirm that extract and replacement air still work together under the current building arrangement.
Gas equipment needs its own maintenance and safety checks
HSE says gas appliances, flues, pipework and safety devices in catering premises must be maintained in a safe condition and inspected by competent people in accordance with current industry practice. Gas work must be completed by appropriately qualified Gas Safe registered engineers.
Where ventilation and gas systems are interlocked, changes or faults in the ventilation can affect whether gas appliances are allowed to operate. Do not bypass safety controls to meet an opening deadline.
Should the extraction be cleaned before reopening?
That depends on the system condition, last cleaning date, previous findings, access, current evidence and any landlord, insurer, fire-risk or maintenance requirement that applies to the site.
If contamination is present or the evidence is poor, competent kitchen extract inspection or cleaning may be appropriate. If the main issue is fan performance, controls, replacement air or a changed kitchen layout, a different specialist route may be needed.
Historic pre-opening project context
The EC Cleaners project archive includes restaurant work completed ahead of openings and changes of use. These projects illustrate the value of checking the complete extraction route, fan, access and evidence before the trading date becomes the only priority.
Historic EC Cleaners project imagery is used for pre-opening context. It is not presented as evidence of the condition of another closed or reopening restaurant.
What should you collect before reopening?
- Latest extract cleaning report and certificate. Keep the full report with the certificate.
- Fan and mechanical service records. Identify outstanding maintenance or previous faults.
- Ventilation information. Keep drawings, commissioning records and performance information where available.
- Access history. Record roof access, risers, access panels and previously inaccessible sections.
- Refurbishment records. List changes to equipment, layout, ductwork, controls and replacement air.
- Gas-safety records. Keep relevant gas servicing and safety information separate from extract hygiene evidence.
- Fire-risk and insurer actions. Carry forward any outstanding requirement through the reopening process.
- Opening plan. Set out the intended equipment, menu, production and trading hours.
Which specialist route may be appropriate?
Extract contamination
Where grease contamination or overdue cleaning is identified, competent kitchen extract cleaning may be required.
Fan or controls
Mechanical, electrical and controls faults should be handled by the appropriate competent specialist.
Ventilation suitability
If the cooking operation or building arrangement changed, competent ventilation review may be needed.
Access limitation
If parts of the ductwork or fan cannot be reached, enabling access may be required before full inspection or maintenance.
Unclear records
If the inherited evidence is incomplete or contradictory, organise the records before issuing contractor instructions.
Reopening a closed restaurant: frequently asked questions
What should I check before reopening a restaurant that has been closed?
Check the kitchen extraction system route, latest cleaning and maintenance records, fan operation, controls, replacement air, known access limitations, visible contamination, outstanding repairs and any changes made to the kitchen or building while the premises was closed.
Does a period of closure mean the kitchen extract system is still clean?
No. Closure does not prove the system is clean or suitable. Existing grease deposits, inaccessible sections and unresolved maintenance issues can remain even when the kitchen has not been trading.
Should the extract fan be tested before reopening?
Yes, where appropriate within a competent pre-opening inspection or maintenance process. The fan, controls and wider ventilation system should be checked so the operator understands whether the system is operating as expected before normal cooking resumes.
What if the previous cleaning report is old?
Treat it as historic evidence rather than proof of current condition. Compare the date, scope, photographs, access limitations and outstanding actions with what has happened at the premises since the report was issued.
What if the restaurant was refurbished while it was closed?
Any change to cooking equipment, canopy position, ductwork, fan, replacement air or kitchen layout can affect ventilation performance. The updated system should be reviewed against the intended operation before reopening.
Do gas appliances need extra checks before reopening?
Gas equipment and associated safety devices should be maintained in a safe condition and inspected by competent people in accordance with current industry practice. Gas work must be carried out by appropriately qualified Gas Safe registered engineers.
What records should I collect before reopening?
Collect extract cleaning reports, certificates, fan and mechanical service records, ventilation or commissioning information, gas-safety records where relevant, fire-risk actions, insurer requirements, access information and details of any refurbishment or building work completed during closure.
Preparing to reopen a restaurant after a period of closure?
Send the inherited records, reopening date, current equipment and details of any refurbishment. EC can help organise the cleaning history, fan and ventilation information, access issues and new operating requirements so the appropriate independent specialists can be approached before opening.
