About this service
A permanent supply to a garden office, studio, workshop or shed is designed as part of the property’s electrical installation. It may include an armoured or otherwise suitable cable, local distribution, lighting, sockets, heating, data and outdoor equipment.
Distance, ground conditions, earthing and the intended load all affect the design. A small office with a laptop and heater is different from a workshop, gym, hot tub or building that may later receive solar panels.
Common problems we help with
Building is supplied by an extension lead
Long-term outdoor use can expose unsuitable plugs, sockets and cable to water and damage.
Voltage drop affects equipment
Long cable runs and larger loads require calculation, not selection by guesswork.
No route was allowed before landscaping
Finished paving and gardens can make safe cable installation more disruptive.
Wi-Fi and data are unreliable
Power planning often overlooks a wired network link or suitable route for communications.
How we carry out the work
Define how the building will be used
We list heating, office, workshop, gym, charging and future loads.
Design supply, earthing and route
Cable size, installation method, isolation and local distribution are selected for the site.
Install final circuits and test
Power, lighting and controls are fitted, labelled and tested with the complete supply.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed garden building & outbuilding power work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- The exact result expected from the garden building & outbuilding power work
- Condition and capacity of the existing circuit
- Cable routes, access and protection of finishes
- Testing, certification and any future requirements
What affects the price?
The price depends on the existing installation and the amount of work required. For garden building & outbuilding power, the main factors normally include:
- Extent of the work and material specification
- Accessibility and working conditions
- Alterations needed to the existing installation
- Inspection, testing and documentation
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- Completed electrical test results
- Applicable certificate or minor-works record
- Operating and isolation explanation
- A written record of the completed work
Garden Building & Outbuilding Power questions
Can I run armoured cable along a fence?
A route must provide suitable support and protection. A fence is not automatically an appropriate permanent support.
Does the outbuilding need an earth rod?
Not always. Earthing design depends on the supply arrangement and building services and must be assessed for the installation.
Will the work need Building Regulations notification?
A new circuit and outdoor installation may be notifiable domestic work. The compliance route should be confirmed before starting.
