- Wok cooker & steamer servicing & repair
- Extract duct cleaning
- Gas Interlock System (G.I.S.)
- Gas Safety Check
Wok cooking ranges work in a tough environment, regular maintenance is essential to ensure good performance. Carbon deposits, grease residue, high temperatures and mechanical wear can all lead to breakdowns.
Your wok cooker should be serviced at least once per year replacing all thermocouples and pilot lights, regreasing gas valves if necessary and inspecting the burners and flame picture to see if the jets require attention.
Grease builds-up in kitchen extraction systems, reducing performance, becoming a fire hazard and potentially closing your business if it stops your fan blades rotating. To keep things running smoothly, your ducting and fan should be cleaned every 6–12 months.
Our professional cleaning improves airflow, extends fan life, and keeps your kitchen safe. We also inspect your fan and check filters for optimal performance.
We offer nationwide service from £400+VAT please contact us with your site address, photos of your canopy and external ducting for a quote.

Control panel & emergency stop
A Gas Interlock (control panel shown above) checks your kitchen extract fan is running before allowing gas to flow. They’re required on commercial kitchens where gas appliances have been fitted after September 2001. If the fan stops, stops the gas to prevent dangerous fumes building up.
A supplied and fitted system typically costs £1,100–£1,500+VAT, depending on your gas pipe size. If you just need the control panel, the cost is around £300+VAT.
Air pressure sensing vs Current sensing
There are two types of fan status detection: Air pressure (shown above) and electrical current sensing. We only fit current sensing as they are more reliable because there are no pipes to block with grease or rubber hoses that can be accidentally disconnected.
Proving option
After checking fan speed (via air pressure or electric current), the pressure proving upgrade tests gas pipes for leaks or open valves before allowing gas flow. Proving is required where equipment lacks a Flame Safety/Supervision Device (FSD) thermocouple that cuts gas supply to unlit burners.
These appliances will be non-CE made before 1997; the costs of upgrading to a proving interlock may be better spent on modern replacement catering equipment.
A non-proving solenoid (electric gas valve) is shown above, proving versions have an additional small pipe(s) typically in the middle.


Do I need a Gas Safety Check?
Yes, it's required by law, your local authority, and your insurance provider - every year. Without it, your insurance may be invalidated, and you could face an enforcement notice from your council's environmental health officer.
How much does it cost
A Gas Safety Check Certificate costs around £220+VAT, depending on your location and the number of gas appliances in your kitchen.
How do I book?
To book, simply email or call using the contact details at the bottom. Please advise your address, times we can inspect and the gas appliances in your kitchen.
What happens during a Gas Safety Check and how long does it take?
Just like an MOT for your kitchen: a qualified engineer safety inspects everything gas-related - cooking equipment, extract canopy and fan, gas meter and pipework, they'll then advise of any defects found. It usually takes up to 2 hours and can be done while your chefs are prepping (but not cooking).
What equipment and premises do you work on?
We are commercial catering specialist engineers working on takeaways, restaurants, pubs, cafes, hotels, schools, nursing homes, and community centres. We no longer service domestic premises, LPG or mobile catering trailers. COMCAT1 (Cookers, ranges and ovens, bain marie, hot cupboard, stoves, hot plates, boiling tops), COMCAT3 (deep fat fryers, griddles and grills), COMCAT4 (Fish & Chip range) and COMCAT5 (forced draught turbo burners).
