Three-phase power in Haringey comes up in two places: the large period homes of Crouch End and Muswell Hill taking on serious modern loads, and Tottenham’s workshops and light-industrial units. GFL Electrical design and install three-phase supplies and upgrades across the borough.
What three-phase is, and when you need it
Homes usually run single-phase; three-phase (around 400V) supplies far more power, needed for:
- High-demand homes — heat pump + 22kW EV charger + battery storage together
- Workshop and light-industrial machinery
- Commercial units with heavy loads
Haringey’s three-phase demand
- Large homes in Crouch End and Muswell Hill (N8/N10) — substantial period houses where a deep green retrofit (heat pump, fast charging, battery) can exceed single-phase capacity. See our heat pump electrical guidance.
- Tottenham workshops and light-industrial units (N17) — equipment that needs three-phase as standard.
The upgrade process
Single- to three-phase involves the DNO: we assess your load, apply to the DNO for the supply, and install the three-phase board and circuits to BS 7671, managing the DNO liaison for you.
See our main three-phase installation service.
Common questions about three-phase in Haringey
My large Muswell Hill home is going all-electric — three-phase? Possibly — if the combined heat pump, EV charger, and battery exceed single-phase, yes; we assess total demand.
My Tottenham workshop needs more power — can you supply three-phase? Yes — three-phase supplies and machinery circuits are core work for us.
Is three-phase needed for a standard EV charger? No — only for 22kW or stacked heavy loads.
