Do you need some electrical work for your business or industrial space, but are unsure what to look for in a commercial electrical contractor?
Take a minute to read through our Commercial Electrician Guide so that you can make the best decision for your business.
It is important to understand the type of electrical contractor you need, so let us show you the difference between a commercial and residential electrician, so you can find the perfect fit.
What is the Role of a Commercial Electrician Compared to a Residential Electrician?
While residential and commercial electricians are both trained professionals, their scope of work differs significantly.
Residential electrician: handles wiring, sockets, lighting, and consumer units in homes. Their projects are often smaller in scale and less complex.
Commercial electrician: responsible for large-scale electrical installations, maintenance of complex systems like industrial machinery or safety alarms, and ensuring compliance with strict commercial regulations.
Our Approved Electricians Are On Hand For All Your Needs
We’re happy to have some of the best technical approved electricians at Maidenhead Electrical Ltd who are educated, knowledgeable and experienced in all things electrical.
Take our work at Eton College as a case study
Our approved electricians carried out specialist electrical refurbishment work at the Provost’s Lodge at Eton College, a listed and historic building.
Working in such heritage sites requires expert knowledge and care, which MEL’s experienced team provides.
Under the leadership of Director Andy Collins and Approved Electrician Ryan Ward, the project is progressing on schedule, with old wiring stripped and careful first-fix wiring underway.
MEL places great pride in attention to detail and preserving the building’s integrity, ensuring all work is done safely and respectfully.
Businesses needing electrical work in historic buildings can rely on MEL’s specialised services.
Being Responsive Communicators & Available Quickly
When deadlines are tight and disruption is costly, responsiveness and availability become deal-breakers. A good commercial electrical contractor should:
Reply promptly to enquiries
Provide realistic timelines
Be flexible enough to handle urgent requests or fast-track projects
Communicate clearly throughout every phase
Take us at Maidenhead Electrical Ltd, for example. We knew from an early stage that keeping clients happy, no matter the time, would be the key to having a successful electrical business.
We knew that things could go wrong in businesses. And in emergencies, you don’t want to wait until the morning.
So, we started our on-call service.
An on-call team who are available 24 hours a day, 7 days a week, all year long.
So that when those emergencies inevitably pop up, our on-call engineers will get you back up and running in no time.
Whether you call us through our direct line, 01628301188, send us an email at, mel@maidenheadelectrical.co.uk, once you’re onboarded as a client you will have direct access to our internal team.
We take the stress away. From mid-refurbishment or reacting to a sudden breakdown, poor communication causes delays and stress.
The best contractors prioritise speed, while maintaining high work standards.
Certifications, Qualifications and Experience Matters When Looking For Commercial Electrical Contractors
Any contractor can claim to be skilled, but certifications and qualifications prove it.
Our company is:
CompEx approved.
Construcaline Social Value Certification
Constructionline Gold Member Approved
Acclaim Accreditation
Alcumus Safe Contractor Approved
Achilles UVDB Silver Plus
ISOQAR ISO 9001 Certification
Strong case studies, references, and a history of completing complex installations reinforce a contractor’s credibility. With 42+ in-progress sites, 1800 projects completed and 250+ customers, we prioritise long-term relationships with our clients, ensuring they always remain running.
Industry experience also shows they can adapt to unique challenges and evolving technologies, whether installing LED systems or upgrading legacy infrastructure.
Take a look at some of our case studies below:
We’ve worked on some incredible projects, from sorting out restaurant lighting with Lego’s Hotel Resort, to one of our most recent projects with BA at Heathrow Airport.
Maidenhead Electrical Ltd partnered with Johnson Controls Ltd to deliver vital electrical infrastructure projects.
Our work included refurbishing high-security control rooms with precision rewiring, upgraded lighting, and future-proof systems, completed without disrupting operations.
We also designed and installed robust UPS systems to ensure uninterrupted power supply.
Operating under intense pressure in a live airport environment, our team showcased exceptional skill, compliance, and professionalism, reinforcing their reputation as a trusted electrical partner for major blue-chip clients in the aviation sector.
What About Insurance and Compliance?
Electrical work carries risk, especially in commercial or industrial settings. That’s why compliance and insurance aren’t optional extras; they’re essential.
Your chosen contractor should hold:
Public liability insurance (covering damage to your property)
Employer’s liability insurance (for their team)
Professional indemnity insurance (for design and consultancy)
Ask about health and safety procedures, ongoing staff training, and how risk is managed on-site. A contractor who takes compliance seriously is far more likely to deliver safely, consistently, and legally.
Being Transparent on Pricing
In commercial projects, pricing transparency matters, just as much as technical skill. Detailed quotes should break down labour, materials, and any additional charges.
Beware of vague or unusually low estimates as these often hide add-ons that emerge once work begins.
Reliable contractors will:
Offer fixed-rate or clearly structured pricing
Be open about what's included or excluded
Provide design input to manage costs
Going for the lowest-cost option may look appealing, but if corners are cut and cheap materials are used, it often works out more expensive in the long run.
We recommend prioritising the company that has a track-record in complex industrial design processes, project management, high-quality output and clear communication. We recommend prioritising these attributes over fast turn-around times and the lowest cost options.
Having a Solid Client Base and Great Reputation
A contractor’s reputation and client list speak volumes. Look for companies with experience working in your sector, whether that’s schools, heritage sites, hospitals, or industrial estates.
Key signs of a trusted contractor:
Verified client testimonials
Positive online reviews
Long-term relationships with returning clients
Royal Warrants or work on nationally significant projects (as seen with some top-tier providers)
Take a look at some of our great clients:
Eton College
Chelsea Football Club
BA at Heathrow
Glencore
ADT Security
Royal Holloway University
Clivedon House, a National Trust property, managed by Iconic Luxury Hotels
National Physics Laboratory
One of our recent projects was at the Royal Holloway University where we created a state-of-the-art research and production facility as part of the new CoSTAR National Laboratory.
Maidenhead Electrical Ltd successfully completed a complex and cutting-edge project at Royal Holloway, University of London, converting seminar and office spaces into state-of-the-art research and production facilities as part of the new CoSTAR National Laboratory.
Working alongside LST Projects and RHUL’s estates team, MEL converted seminar and office spaces, managing the electrical design and installation, including LV distribution, lighting, power, alarms, and AV support. The lab supports national R&D in AI, screen and performance technology.
MEL’s team, led by Site Supervisor Ryan Ward and Contracts Manager Dave Searle, kept the project on track through flexible coordination and high standards.
A key highlight was the installation of Thorlux smart scan lighting to boost energy efficiency. The project reflects MEL’s commitment to innovation, partnership, and delivering outstanding work on prestigious, future-focused initiatives.
