Outdoor and commercial power starting prices
Starting prices reflect standard connection points and baseline protective bonding. Final totals vary with cable run lengths, ground conditions and the capacity of your consumer unit.
From £230
Earthing and bonding: from £230
Within the agreed scope
- Installing steel wire armoured cable clipped direct or ready for prepared trenches
- Fitting weatherproof rotary isolators, outdoor sockets and dedicated sub-distribution boards
- Connecting main protective bonding conductors to gas and water service pipework
- Testing circuit continuity, earth fault loop impedance and insulation resistance
- Commissioning new distribution boards with clearly marked circuit directories
Confirm separately
- Ground excavation, trench digging or making good through landscaped gardens and tarmac
- Increasing the incoming statutory supply fuse rating or network operator supply capacity
- Purchasing consumer appliances, hot tubs or electric gate automation mechanisms
- Making good specialist decorative wall finishes after internal cable installation
Ways to pay
- Pay by bank
- Bank transfer
- Cable installation through finished ground, trenching or specialist containment is quoted following an on-site survey.
- Earthing and bonding starting rates apply to your initial incoming service pipe, with additional service pipes priced individually.
- Hardware such as electric gate motors, garden lighting fittings or specific machinery must be on site before cable installation.
- Any required consumer unit upgrades or supply capacity increases from your network operator are assessed and quoted separately.
Outdoor and commercial power explained
Outdoor circuits and commercial connections require dedicated cable sizing, weatherproof switchgear and correct protective bonding to manage heavy electrical loads safely.
- Outbuildings and garden powerRunning electricity to garden offices, workshops or sheds demands armoured cabling buried at correct depths. We connect sub-boards in outbuildings across Wandsworth and Clapham to run heating, power and lighting without overloading domestic consumer units.
- High-demand residential equipmentHot tubs, electric entrance gates and external heating units draw significant current that standard house circuits cannot carry. We fit dedicated radial connections with separate rotary isolators and RCD protection tailored to manufacturer specifications.
- Three-phase supplies and commercial unitsCommercial premises, workshops and larger properties in areas like Battersea and Fulham often require 400V three-phase distribution. We configure distribution boards to balance phase loads cleanly across machinery, lighting and kitchen appliances.
- Main protective bondingConnecting metallic service pipes such as gas and water to the main earthing terminal prevents exposed metalwork from carrying dangerous voltages during an electrical fault. Upgrading bonding is essential before connecting high-capacity outdoor power.
What happens on the day
Careful preparation ensures cable runs can be installed cleanly with minimal disruption to your home or commercial premises.
- Surveying cable pathways and intake pointsWe inspect your incoming supply head, consumer unit and the planned path to the outdoor or commercial equipment. Clear access along internal walls, basements or garden pathways helps us verify physical clearances.
- Isolating supplies during connectionConnecting new high-capacity circuits or distribution boards requires planned electrical shutdowns. We schedule power interruptions in advance so home routines or business trading can continue with minimal disruption.
- Testing and final switchgear inspectionOnce cables are fixed and connected, we conduct electrical safety tests on every new conductor and verify protective device tripping speeds before energising the system.

WhatsAppWhy do outbuildings need steel wire armoured cable?
Cables running outdoors or underground must resist impact from gardening tools, wildlife and weather. Steel wire armoured cable provides mechanical protection and a resilient outer sheath, ensuring the circuit remains safe over years of exposure.
How do I know if my property needs three-phase power?
Standard homes run on single-phase 230V electricity. Properties with large commercial machinery, multiple fast vehicle chargers, extensive air conditioning or large electric heat pumps may exceed single-phase capacity and require a 400V supply.
What is the difference between earthing and bonding?
Earthing provides a path for fault currents to safely flow to ground and trip protective devices. Bonding connects incoming metal pipes like gas and water to earth, preventing dangerous voltage differences between pipework and electrical appliances.
Can a hot tub connect to a normal outdoor socket?
Most hot tubs require a dedicated radial circuit run directly from your consumer unit, controlled by a rotary isolator switch placed within sight of the tub. Standard 13-amp sockets cannot safely carry the continuous heating and pump loads.
Will you dig trenches for outdoor cables?
Our work covers running, clipping, terminating and testing electrical cabling. Trenches must be excavated to standard depths before installation, or arranged through groundworks contractors prior to cable pulling.
