Transform your cold, dusty garage into a warm, fully powered living space. We provide complete electrical design and installation services for garage conversions, annexes, and home offices.
Converting a garage is one of the most cost-effective ways to add value and square footage to your home. Whether you are creating a new home office, a gym, a playroom, or a self-contained “Granny Annex,” the success of the project depends on the infrastructure. A garage was built for a car, not for people. It likely has one dim lightbulb and a single socket for a lawnmower.
To turn it into a habitable room, you need a robust electrical system that meets modern Building Regulations. At Yare Electrical, we work alongside you (and your builders) to design a power and lighting setup that makes your new space comfortable, functional, and safe.
Building a Home Office?
Don’t rely on patchy Wi-Fi. We install hard-wired data points for rock-solid internet speeds.
The Power Supply: Why You Need an Upgrade
The most common mistake homeowners make is assuming the existing cable feeding the garage is sufficient. Usually, it is not.
If you are insulating the walls and installing electric heating, computers, TVs, and appliances, the electrical “load” will increase significantly. The old cable that ran a single light bulb will likely overheat or cause voltage drops if you try to run a modern office from it.
Our Solution: A Dedicated Sub-Main
We typically install a new, heavy-duty Armoured Cable (SWA) from your main house fuse board directly to the garage. We then install a new “Mini Consumer Unit” (Garage Board) inside the conversion. This offers two huge benefits:
- Safety Capacity: It safely handles the high power demands of electric radiators and showers.
- Local Control: If a faulty heater in the garage trips the fuse, it won’t plunge your main house into darkness.
Heating Your New Space
Garages are notoriously cold. Extending your main gas central heating system to a detached or semi-detached garage is often expensive and messy (involving digging up driveways for pipes). The modern alternative is Electric Heating.
Electric Radiators
We supply and install highly efficient, Lot 20 compliant electric radiators. These are not the inefficient heaters of the past. They are smart, Wi-Fi connected units that allow you to warm up the office from your phone before you leave the house in the morning.
Electric Underfloor Heating
For a touch of luxury—especially if you are installing a tiled floor or a gym—we can install electric underfloor heating mats. These provide a gentle, even heat that doesn’t take up any wall space, leaving you more room for furniture.
The Home Office Essentials: Data & Connectivity
If your conversion is for a home office, reliable internet is more important than electricity. Wi-Fi signals struggle to penetrate through external brick walls and the new foil-backed insulation used in conversions.
We don’t leave you struggling with boosters. We install:
- CAT6 Ethernet Cabling: A hard-wired data cable running from your internet router in the house to data sockets in the garage wall. This guarantees full-speed, lag-free internet for Zoom calls.
- USB Integrated Sockets: We install double sockets with built-in USB-A and USB-C charging ports, freeing up plug sockets for your monitors and printer.
Lighting Design for Low Ceilings
Garage ceilings are often lower than standard rooms. Hanging a pendant light in the middle of the room can make the space feel cramped (and tall people might hit their heads!).
We recommend Recessed LED Downlights. These sit flush with the ceiling, maximising headroom and making the space feel larger and airier. We can zone the lighting so you have bright, cool-white light over the desk for working, and softer, warm-white light in the seating area for relaxing.
Creating Self-Contained Annexes
If you are converting a garage into a bedroom or “Granny Flat,” the electrical requirements become more complex, especially if you are adding a kitchenette or bathroom.
Kitchens & Cooking
We wire dedicated circuits for induction hobs and electric ovens. Even a small kitchenette needs careful load calculation to ensure the kettle, toaster, and microwave can all run at once without tripping the power.
Bathrooms & Showers
Bathrooms are “Special Locations” under BS7671 wiring regulations. We install IP-rated lighting and extraction fans to remove moisture and prevent mould. If you are installing an electric shower (which draws a massive 9kW-10kW of power), we ensure the supply cable is thick enough to handle it safely.
Building Regulations & Certification
A garage conversion is a “Change of Use” and requires Building Control approval. The electrical work falls under Part P of the Building Regulations.
You cannot use an unregistered electrician or do this work yourself. You need a certificate to prove the conversion is legal.
- We Are Part P Registered: We handle the notification process for you.
- The Certificate: Upon completion, we issue an Electrical Installation Certificate (EIC) and notify your local authority. You present this to your Building Inspector to get the final sign-off on your project.
Working With Your Builders
We are experienced in working on busy building sites. We coordinate our visits to fit your schedule:
- First Fix: We arrive when the stud walls are up (but before the plasterboard is on) to run all the cables and install back boxes.
- Second Fix: We return once the plaster is dry and the room is painted to screw on the shiny new sockets, hang the lights, and test the system.
