100% Brechin Local.
I served as a Retained Firefighter with Brechin Fire Service and a Royal Air Force Electrical Engineer. I've seen garage fires caused by overloaded extension leads and DIY wiring disasters.
When I wire your outbuilding, I use properly rated armoured cable buried to regulation depth. Your workshop power supply will be as robust as the military installations I worked on. Safe. Legal. Built to last.

SWA Cable Options & Capacity
Steel Wire Armoured (SWA) cable is the only legal option for underground power runs. Here's what cable size you need.
2.5mm²
SWA
For light and socket circuits only. Max load: 20A. Good for basic garden sheds with LED lighting and occasional power tool use.
4mm²
SWA
For standard garages. Max load: 32A. Handles workshop sockets, LED lighting, and small heaters. Most common specification.
6mm²
SWA
For workshops with heating. Max load: 40A. Supports electric heaters, compressors, and EV charger preparation.
10mm²
SWA
For heavy industrial use. Max load: 63A. Required for long cable runs, three-phase supplies, or EV charger + full workshop.
Do You Need A Sub-Board?
If you want multiple circuits in your outbuilding, a mini consumer unit is the right approach.
Single Circuit
No Sub-Board
Just lights or just sockets
Multiple Circuits
Sub-Board
Lights + sockets + heating
We Install: Hager or MK Sub-Boards

Safety Warning: DIY Garage Wiring Is Illegal
Outbuilding electrical work is notifiable under Part P Building Regulations. DIY installations are illegal, dangerous, and void your home insurance.
We provide full certification for building control sign-off. Standard twin & earth cable buried underground will kill. Only armoured SWA cable is legal.
OurOutbuilding Wiring Installation Process
From survey to final switch-on, we make it simple and stress-free.
Survey & Design
We measure cable routes, check your existing consumer unit capacity, and design a compliant installation tailored to your needs.
Cable Trench
We dig trenches to 450mm depth (or 600mm under driveways), lay SWA cable, and mark the route with warning tape for future safety.
Board Installation
We install mini consumer units in your outbuilding (if required), connect the SWA feed, and fit RCD/RCBO protection for all circuits.
Fit Out & Testing
We install sockets, lights, and switches. We test everything (earth continuity, insulation resistance, RCD trip times) and issue certificates.

Garage & Outbuilding Wiring FAQs
? Can I use normal cable for my garage?
No. Underground or external cable runs must use Steel Wire Armoured (SWA) cable. Standard twin & earth cable degrades outdoors and is a fatal fire/shock risk.
? Do I need planning permission to wire my shed?
Not usually for electrical work alone. However, if you're building a new outbuilding over 15m² or within 1m of a boundary, you may need planning consent or building notice.
? How do you heat a garden office?
We typically install a dedicated circuit for electric panel heaters (2-3kW). Infrared heaters are also popular. Oil-filled radiators can overload standard socket circuits.
? Can you install three-phase power?
Yes, if your main property has a three-phase supply. Common for workshops with large machinery, commercial garages, or pottery kilns requiring 400V equipment.
? Can I add an EV charger to my garage circuit?
Only if the garage has its own dedicated sub-board with spare capacity. EV chargers need a separate 32A circuit—they cannot share with lights/sockets.
? How deep does SWA cable need to be buried?
450mm under soft ground (lawn/flower beds). 600mm under driveways or areas with vehicle traffic. We always lay warning tape 150mm above the cable.
? Do I need a new consumer unit in my garage?
Only if you want multiple circuits (e.g., sockets + lights + heating). For single circuits, we can run directly from your house consumer unit if there's capacity.
? Can you run cable through my loft space?
Yes, if the garage is attached. We use SWA cable in lofts due to fire regulations and clip it securely to avoid contact with insulation or timbers.
? What size cable for a 20-meter garage run?
Depends on load. For basic sockets and lights (20A), 4mm² SWA is fine. For workshops with heating (32A+), we use 6mm² SWA to handle voltage drop.
? Can I install sockets myself and get you to connect?
No. The entire installation must be designed, installed, and tested by a qualified electrician for Part P compliance. We cannot certify work we didn't perform.
? Do you install data/network cables?
Yes. We run Cat6 or Cat6a ethernet cables for garden offices, enabling gigabit internet speeds for remote working or streaming.
? How much does garage wiring cost in Brechin?
Basic garage power (sockets + lights): £600-£900. Workshop sub-board package: £1200-£1800. Garden office full fit-out: £2000+. Depends on distance and complexity.
? Can you wire my summer house for hot tub use?
Yes, but the hot tub circuit must be separate with dedicated RCD protection. We can design a dual-purpose installation with one circuit for the building and one for the spa.
