Fitting out a commercial kitchen?
Commercial Kitchen & Catering Electrical Services
Commercial kitchens are demanding environments to wire up. You’ve got heavy equipment loads, high temperatures, water, steam, grease, and tight regulations all in the same space, and the electrical installation has to stand up to every bit of it. We work with kitchen designers, catering equipment suppliers, restaurants, hotels, schools, and care homes across Cornwall to deliver kitchen electrical installations that are safe, compliant, and built to last. From IP-rated fittings and canopy interlocks through to heavy appliance connections and emergency shut-off systems, we know what a commercial kitchen needs and we know how to deliver it properly.

Top Questions & Answers
Here are the top questions we’re frequently asked about 3-phase power installations…
Yes, this is how most of our commercial kitchen projects start. We work directly from the equipment schedule, kitchen layout, and any electrical or mechanical drawings provided by the kitchen designer or catering equipment supplier. If the design is still being developed, we can also get involved early to advise on circuit requirements, load distribution, and any infrastructure that needs to go in before the kitchen fit-out begins.
Absolutely. A lot of commercial catering equipment runs on three phase, and we install, connect, and test three phase circuits as a regular part of our work. If your incoming supply is single phase only, we can assess whether an upgrade is needed and liaise with the DNO on your behalf if required. We’ll let you know early in the project whether the supply is going to need attention so it doesn’t become a problem further down the line.
A gas interlock system links the gas supply in your kitchen to the extract ventilation, automatically shutting off the gas if the extraction isn’t running properly. For most commercial kitchens using gas appliances, this is a requirement rather than an option, and it’s an important safety feature regardless. We install and wire the electrical side of the interlock system, working alongside your gas engineer to make sure the complete system commissions correctly.
Most commercial kitchens are required to have clearly identified emergency stop arrangements that can isolate the electrical and gas supplies quickly in an emergency. The exact requirements depend on the setup, the appliances in use, and how the kitchen is laid out. We design and install emergency isolation systems that meet current standards and are positioned where they can actually be reached when needed, not buried behind equipment where they’re useless.
In many cases, yes. Hotels, care homes, and schools often need to keep operating while the kitchen is being refitted, and we plan around that wherever possible. We can phase the work, carry out the noisy or disruptive elements outside of operational hours, and keep temporary power available where it’s needed. We’ll discuss the practicalities at quotation stage so there are no surprises about access or downtime.
WHAT OUR CUSTOMERS SAY

Our 3-Phase Installation Process
BEFORE
Design Review: We review the kitchen drawings, equipment schedule, and any consultant specifications to confirm the electrical requirements for the project in full.
Site Survey: We visit the site to check the existing supply, distribution capacity, and any constraints that might affect the installation before we put a quote together.
Fixed Quote: We send you a clear, itemised quote setting out exactly what the installation includes, what it doesn’t, and what the total cost will be upfront.
DURING
First Fix: We install all containment, cable runs, back boxes, and supplies to the agreed equipment positions, working in coordination with the other trades on site.
Equipment Hook-Up: We connect each piece of catering equipment to its dedicated supply, sized correctly for the load and properly isolated for safe servicing later.
Interlock Wiring: We wire the canopy controls, gas interlock panel, and emergency shut-off systems so the safety arrangements all commission correctly together.
AFTER
Testing: We carry out full testing of every circuit and safety system, confirming the installation performs correctly before anything is energised and put into use.
Certification: We issue all completion certificates and supporting paperwork, giving you a fully compliant record ready for inspection, insurance, and sign-off.
Aftercare: We’re easy to get hold of for any future works, additions, or fault calls, and we can build in planned maintenance visits if that suits your operation.
