EV Charger Home Install Guide EV & Energy # EV charger home installation: a South London guide By [Steve Green](/about) · Updated 30 April 2026 · 9 min read A home EV charger costs **£810–£1,725 fully installed** in South London in 2026, depending on the unit you choose and how far the cable run is. Standard installs (Ohme preferred, EV Ultra cable) typically sit at £810–£1,150, with premium smart-tariff setups reaching £1,150–£1,725. For most homes the install takes half a day. Below is what genuinely matters in the decision — most of which charger sellers won't mention. ## Step 1: Check your supply Before you choose a charger, an installer should check three things: - **Main fuse rating.** Most South London homes have a 60A, 80A or 100A main fuse. A 7kW charger draws ~32A, so we need to check headroom against your peak existing load. - **Earthing arrangement.** TN-S, TN-C-S (PME) and TT systems each have different requirements. PME supplies — common in [Croydon](/areas/croydon), [Bromley](/areas/bromley) and [Sutton](/areas/sutton) — need either an earth-rod-less charger (Ohme, Hypervolt, Wallbox with built-in PEN protection) or an additional earth electrode. - **Consumer unit capacity.** If you're already at the limit, a [consumer unit upgrade](/services/consumer-units) may be required before the charger goes in. ## Step 2: Pick a charger that suits how you actually drive The hardware decision matters less than people think — but a few things genuinely separate good chargers from bad: - **Smart tariff support.** If you're on Octopus Intelligent Go or similar, choose a charger that integrates natively (Ohme, Hypervolt). Off-peak charging at ~7p/kWh vs 28p makes a £600+ annual difference for a typical driver. - **Tethered vs untethered.** Tethered (cable attached) is more convenient day-to-day. Untethered (socket only) is tidier when not in use and future-proof if connector standards change. - **Load balancing.** Essential if your supply is tight — the charger throttles itself when the rest of the house is drawing power. ## Step 3: Apply for the OZEV grant (if eligible) Owner-occupiers of houses no longer qualify, but the **EV chargepoint grant for renters and flat owners** still pays up to £350 toward installation. Anyone in a flat or block of flats — common across [Streatham](/areas/streatham), [Tooting](/areas/tooting) and [Lewisham](/areas/lewisham) — should check their eligibility. We're an OZEV-approved installer and handle the paperwork. ## Step 4: The install itself A typical install takes 3–5 hours and includes: - A dedicated 32A circuit from the consumer unit to the charger location - Either a Type A RCD with DC fault detection or an RCBO Type B (depending on charger) - Cable run via the most discreet route — often through the loft, under floorboards, or around the exterior - Commissioning, earth-loop test, RCD test, and registration with the DNO - Manufacturer's warranty registration and connection to your home Wi-Fi ## Step 5: Notify the DNO By law, EV chargers over 16A must be notified to your Distribution Network Operator (UK Power Networks for most of South London). We handle this — but if a quote doesn't mention it, that's a red flag. ## Common mistakes we see - **Cheap installs that skip load balancing** — leads to nuisance trips on the main fuse - **Wrong RCD type** — a basic Type AC RCD doesn't meet current EV charger regulations - **Outdoor cable runs in clipped T&E** — must be SWA or in suitable conduit ## Get a fixed EV charger quote We're OZEV-approved and install all major brands across South London and Kent.
