Bespoke Garden Office Electrical Services
Garden offices and outbuildings have become more than just add-ons — they’re essential spaces for work, creativity, wellness, and connection. Whether you’re running a business from your garden, building a peaceful studio, or adding a gym, bar, or retreat at the end of the lawn, one thing is certain: you need safe, smart electrics that do more than just turn the lights on.
At SFR Electrical Services, we provide expert electrical installations for garden rooms and outbuildings across West Sussex, Surrey, and Horsham. From the initial cable route through to the final socket test, our team handles every detail with care ensuring your space is powered, connected, and fully certified to current UK safety standards.
We understand how important it is to get your new space right. That’s why we tailor every installation to your needs, factoring in power for heating and tech, smart lighting, stable internet, and future-proofed solutions that blend seamlessly with your garden design.
Garden Rooms & Outbuilding Electrical Services
Every garden building is different, so we tailor our electrical installations to suit how you plan to use the space. Whether it’s a quiet garden office, a home gym, or a multi-functional studio, we’ll make sure it’s wired to handle your everyday needs, safely and efficiently.
Underground Armoured Cabling
We run safe, heavy-duty steel wire armoured (SWA) cabling underground from your main house fuse board to the garden room. This ensures a reliable, weatherproof supply that meets all safety standards.
Internal Consumer Unit (Fuse Box)
We install a dedicated fuse board inside the garden room to control your lighting, power and heating circuits. This gives you full protection, independent control, and allows easy future upgrades if your needs grow.
Power Sockets & USB Charging Points
Need plenty of sockets for computers, tools, or equipment? We install double sockets where you need them most — and we can add integrated USB outlets to keep phones, tablets and other devices charged without clutter.
Lighting Design & Installation
From simple LED ceiling lights to warm ambient lighting and adjustable spotlights, we’ll make sure your space is well-lit and fit for its purpose. We also offer dimmers and motion sensors for convenience and energy efficiency.
Outdoor & Decking Lights
If you have a patio, pathway or decking area outside the garden building, we can fit weatherproof outdoor lighting that extends your usable space into the evening and enhances your garden’s look and feel.
Heating & Comfort Features
We can wire up wall-mounted electric radiators, underfloor heating systems, infrared panel heaters or plug-in heaters — helping you use your outbuilding comfortably all year round, even in winter.
Data Cabling & Internet Connectivity
For garden offices or studios, we provide Cat6 ethernet cabling so you can connect directly to your broadband router. This ensures reliable high-speed internet perfect for video calls, streaming or working from home.
External Sockets & Waterproof Outlets
For garden offices or studios, we provide Cat6 ethernet cabling so you can connect directly to your broadband router. This ensures reliable high-speed internet perfect for video calls, streaming or working from home.

- Garden bars with fridges and sound systems
- Gym machines like treadmills and rowers

Garden Offices Built to Last
A modern garden room or outbuilding deserves more than temporary electrics or makeshift power. Whether you’re using the space year-round or seasonally, we ensure every installation is durable, user-friendly, and able to support your day-to-day needs.
All systems are designed with:
- Daily usage in mind – power-hungry equipment, heating, and lighting
- Longevity and minimal maintenance – quality components that stand up to time and weather
- Discreet, tidy cabling – clean routing to preserve the look and feel of your garden
- Smart control options – for convenient lighting and energy-saving automation
- Scalability – ready to adapt if your needs grow (e.g. adding air con, networking, or more devices)
Our approach goes beyond “just enough.” We future-proof your outbuilding so it works as reliably and safely as the rest of your home — even as your lifestyle or setup evolves.
