What we do
What we deliver
Fixed Wire Testing (EICR)
An Electrical Installation Condition Report (EICR) gives you a clear picture of the condition of your electrical installation – what is safe, what needs attention and where improvements should be considered. Prolec carries out fixed wire testing and EICRs.
Commercial PAT Testing
Portable appliance testing keeps your equipment records current and provides evidence that electrical equipment is being appropriately maintained. We carry out PAT testing for commercial and public sector organisations.
Load Monitoring
If you are planning to add significant electrical demand to your installation, or investigating unexplained trips and failures, load monitoring gives you accurate data on what your system is actually doing.
Fire Alarm Testing
Fire alarm systems need regular inspection and testing to help ensure they remain operational and faults are identified. Prolec provides fire alarm testing and inspection for commercial premises across London and the South East.
Emergency Lighting Testing & Maintenance
Emergency lighting plays an important role in helping people leave a building safely if the normal lighting fails. Regular testing and maintenance help ensure the system works when needed.
Thermal Imaging
A thermal imaging survey can identify temperature changes while your system is operating under load, helping you identify potential problems before they lead to failure.
Electrical Remedial Works
An EICR with C1 or C2 observations needs to be acted on. We carry out electrical remedial works for commercial premises across London and the South East, addressing defects identified through inspection and testing, and providing the appropriate certification and records once the works are complete.
Commercial EV charging installation
Demand for workplace and fleet charging is growing fast, and the infrastructure decisions you make now will shape what you can do for the next decade. We design and install EV charging solutions for commercial and education sites across London and the South-East.
LED Lighting Upgrades
Replacing your existing lighting with LED is one of the most straightforward ways to reduce energy consumption across your estate. We survey your installation, specify the right solution for each space, and carry out the full replacement - retrofit where appropriate, full refit where it is not.

FAQs
Straight answers to the most common questions about commercial electrical installation.
How can I tell if my business needs a three-phase power installation?
Your business likely needs a three-phase power supply if you operate heavy machinery, large motors, commercial-grade kitchen equipment, or powerful air conditioning units. It delivers a more stable and robust current than a standard supply, which is critical for running high-demand equipment safely and efficiently.
Are your commercial electricians fully licensed and insured?
Yes, every member of our team is a fully licensed, qualified, and insured electrician. We are accredited by all relevant industry bodies, and our work is performed in strict adherence to national safety standards, ensuring your business, property, and staff are fully protected.
Do you handle complete electrical fit-outs for new commercial spaces?
Yes, we provide end-to-end electrical fit-out services. Our process includes initial consultation and design, complete installation of power, lighting, and data systems, and final testing and certification, ensuring your new business space is safe, compliant, and ready for operation.
How do you determine the cost for a commercial electrical project?
Costs are based on the scope and complexity of the work required. For smaller jobs like repairs or testing, we often have standard rates. For larger projects like a full rewiring or a new fit-out, we provide a detailed, itemised quote after a thorough assessment. We are committed to transparent pricing, so you will understand all costs before work commences.
What is an EICR and how often does my business need one?
An Electrical Installation Condition Report (EICR) is a crucial inspection of your property’s electrical systems to ensure they are safe and compliant with national standards. For most commercial properties, an EICR is legally required at least every five years, though businesses with heavy public use or specialised equipment may need more frequent checks.
Are your electricians qualified to work on heritage or listed buildings?
Yes, we have electricians experienced in working on listed or historic properties. They are skilled at upgrading electrical systems to meet modern safety standards while respecting and preserving the building’s unique structural and aesthetic character.
Is PAT Testing a legal requirement for my business?
Health and safety regulations require employers to maintain all electrical equipment in a safe condition. While not a specific legal mandate itself, Portable Appliance Testing (PAT) is the universally recognised best practice to meet this obligation and is essential for compliance and insurance purposes.
Can you manage complex electrical installations for specialised industries?
Absolutely. We have proven experience in designing and installing complex electrical systems for a wide range of industries, including those that require three-phase power, specialised machinery wiring, data centres, or sophisticated lighting and audio-visual setups.
What are the main business benefits of upgrading to LED lighting?
Upgrading your business to LED lighting offers two primary benefits: significant cost savings on your energy bills and lower maintenance expenses due to their much longer lifespan. LED lighting also provides a high standard of light, which can enhance retail displays, improve workplace productivity, and boost safety and security.
