At Milletts, we pride ourselves on offering a turnkey solution of Electrical Services to meet any demand. Our team works closely with clients from the initial design stage, through to the implementation of the full installation ensuring reliability, safety, and efficiency. Whether you need a comprehensive electrical installation, maintenance, or simple upgrades, we have you covered.
We’ve worked with a wide range of manufacturers of both standard and intelligent lighting systems such as Symtronic, Thorlux, Thorn, CP Electronics, and Modular to name a few. We design and install intelligent lighting systems that incorporate energy-efficient LEDs with advanced controls.
Our small power and containment solutions cover everything from circuits and outlets to more intricate low-voltage systems and full containment installation. We ensure these systems are safely installed and maintained to meet modern standards of functionality while reducing energy waste.
In today’s connected world, reliable data networks are critical. We provide professional design and installation of secure cabling, servers, and connectivity systems to keep your infrastructure running smoothly and your devices seamlessly connected. We also offer an optional 25-year warranty on CAT6A installations.
From consumer unit changes to 3-phase distribution boards and free-standing panel boards, our in-house team have the knowledge and experience to ensure any
industrial power requirement is met and certified to the highest standards. Our safe and efficient distribution systems utilise meticulously designed panel installations, switchgear, load management and metering strategies to ensure uninterrupted power flow on any project.
We offer reliable fire detection and alarm systems that meet strict safety protocols, ensuring that your property is protected and that emergencies are detected early for a swift response.
Our integrated security services include advanced access control systems, door entry, CCTV and intruder alarm systems.
Prevent damage with our lightning and surge protection systems, specifically designed to defend your building and important infrastructure from potential electrical hazards.
Before any project is completed, our thorough testing and commissioning process ensures each electrical installation performs safely and effectively. We make sure every system is fully operational and compliant with the latest regulations before it goes live. We also offer a separate Electrical Installation Condition Report service, ensuring your current installation is safe and compliant.









At Milletts, our Mechanical Services play a crucial role in delivering integrated solutions that enhance the overall performance and efficiency of your building’s systems. By combining our expertise in electrical systems with a comprehensive mechanical service, we enable clients to enjoy seamless, reliable M&E service across all sectors, whether it’s a commercial office, hospital, school, or an industrial facility. Our mechanical services cover three key areas:
We provide professional air conditioning design and installation services. Whether you need cooling for a small office or a large commercial building, we have the experience and expertise to deliver effective and sustainable solutions.
We specialise in the design, installation, and maintenance of ventilation systems and ductwork, all aimed at improving indoor air quality and promoting efficient airflow. Our systems are customised to your specific needs, ensuring that your environment is always healthy and well-ventilated.
Our plumbing and pipefitting services ensure that all water and gas systems are installed and maintained to the highest standards. We provide reliable, long-lasting solutions for both new builds and refurbishments, ensuring everything integrates smoothly into the larger project without disruption. Together, these services allow us to provide a one-stop solution for your mechanical needs.
At Milletts, we’re committed to a sustainable future with our independent Renewables Division. We understand that modern businesses and residences need reliable, eco-friendly solutions to help reduce their carbon footprint and reduce environmental impact and we offer two primary areas of renewable service to do just that.
Our Solar PV and Battery Storage solutions are a vital part of the renewable energy solutions we offer. From residential solar installations to schools, offices and industrial sized Solar PV projects, we have the knowledge and experience to carry out projects of all sizes. Coupled with our advanced battery storage systems, the combination lowers energy costs and helps reduce reliance on the grid, making it a cost-effective and environmentally friendly choice for both residential and commercial properties.
We also offer innovative heat pump systems designed to provide reliable heating and cooling year-round. These systems work by extracting renewable heat from the ground, air, or water to provide energy-efficient climate control for your property. Heat pumps not only reduce energy consumption but also lower your heating and cooling costs. They’re an environmentally conscious choice, as they dramatically reduce greenhouse gas emissions compared to traditional heating systems.
Our expert team installs and maintains these systems, helping you achieve long-term comfort while also fostering sustainability. Through our renewable services, Milletts is helping clients make a positive impact on the environment while saving on their energy bills.
