Garden power

Garden power and outbuilding supplies designed properly

External electrical supplies for garden offices, garages, workshops, outbuildings, outdoor lighting and sockets, reviewed around route, load, protection and future use.

Service overview

External supplies are not simple 'run a cable to the shed' jobs. Route, load assessment, earthing, RCBO/RCD protection, SPD, cable mechanical protection, IP-rated accessories, outdoor isolation, environmental exposure, trenching and future use all need considering before a safe and maintainable installation can be specified.

Technical and compliance considerations

  • Outdoor electrical work should consider environmental conditions, mechanical protection, IP-rated equipment and suitable isolation.
  • Cable routes, RCBO/RCD protection, AFDD consideration, SPD, earthing and isolation should be assessed by competent persons.
  • The current edition of BS 7671, manufacturer instructions and Building Regulations Part P where applicable should be considered.
  • Final design and quotation depend on route, load, access, ground conditions, construction type, intended use and existing installation condition.
  • No customer-facing content should encourage unqualified outdoor electrical installation.

Not just a cable to the shed

Garden and outbuilding supplies can support useful spaces such as offices, workshops, garages and studios, but the design needs to reflect how the space will actually be used. Electric heating, tools, office equipment, lighting, outdoor sockets, unattended equipment, external cable routes, trenching and future expansion can all affect the final design.

Route, load and protection

VLV can review cable route, distance, ground surface, trenching and reinstatement requirements, consumer unit suitability, earthing considerations, RCBO/RCD protection, SPD, SWA or suitable mechanical protection where applicable, IP-rated accessories, outdoor isolation and whether a small local distribution board is suitable.

AFDDs, Timber Structures and Fire-Risk Considerations

Garden rooms, sheds, workshops, timber outbuildings and similar structures can require additional fire-risk consideration. AFDD protection may need to be considered or specified where required or appropriate under the current edition of BS 7671. AFDDs may be relevant where circuits supply socket-outlets or fixed equipment in locations or structures where fire risk, construction type or usage needs additional consideration. Timber construction, combustible materials, hidden cable routes, heating loads, tools, office equipment and unattended equipment can all affect the design approach. Final design depends on the structure, intended use, circuit type, load, cable route, protective devices, installation method and risk assessment. VLV will assess whether AFDD, RCBO/RCD protection, SPD, cable mechanical protection, IP-rated accessories, earthing arrangements and local isolation are required or appropriate.

Future outdoor and energy plans

Where relevant, VLV can consider future garden office expansion, garage use, external lighting, EV-related provision, solar or battery readiness and other outdoor electrical plans so the first stage is not under-specified.
