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.

Built for the Environment

A commercial kitchen is one of the harshest environments any electrical installation has to deal with, and standard fittings simply aren't up to the job. Heat, steam, grease, and regular wash-downs will quickly destroy anything that isn't properly rated for the conditions, leading to faults, downtime, and potential safety issues. We use appropriately IP-rated fittings, sealed accessories, and stainless steel containment throughout, all positioned with proper consideration for where the heat sources, sinks, and cleaning routines are going to be. The result is an installation that copes with the daily reality of a busy kitchen without giving you grief six months down the line.

Heavy Equipment Ready

Commercial catering equipment pulls serious current. Combi ovens, induction hobs, fryers, dishwashers, and walk-in cold rooms all need dedicated circuits sized correctly for their load, and getting this wrong leads to tripped breakers, damaged appliances, and warranty issues with the equipment itself. We work directly from your kitchen equipment schedule, sizing each circuit and connection for the actual appliance going in rather than guessing at typical loads. Whether the equipment is single phase or three phase, hard-wired or plugged in, we make sure every connection is properly specified, properly installed, and properly tested before it's handed over.

Canopy and Interlocks

Extract canopies, gas interlock systems, and emergency shut-off arrangements are an important part of any modern commercial kitchen, and the electrical side of the installation needs to be done properly for the whole system to function as intended. We wire canopies and interlock panels to work seamlessly with the gas safety system, so if extraction fails or an emergency stop is hit, the gas supply isolates automatically as it should. We coordinate with your gas engineer, kitchen designer, and ventilation contractor to make sure the controls, sensors, and shut-offs all work together cleanly when the system goes live.

Compliant and Certified

Commercial kitchens are inspected regularly by environmental health officers, insurers, and fire safety assessors, and the electrical installation needs to stand up to that scrutiny. We complete every job with full testing and certification, providing the documentation you'll need for sign-off, insurance, and any future audit. As NAPIT approved electricians, we work to the current wiring regulations throughout, and we make sure everything from cable management to RCD protection to emergency isolation is exactly as it should be. It's the kind of paperwork that's a pain to chase down later, so we get it sorted at the time and hand it over with the keys.

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.
