Home Electric Vehicle Charger Installation in London: 7kW Wallbox, Part P, and OZEV Grant

THE STANDARD HOME EV CHARGER IN THE UK MARKET IS A 7KW (7.4KW MAXIMUM — 32 AMP SINGLE-PHASE — 230V) AC WALLBOX CHARGER — PROVIDING A TYPE 2 (IEC 62196-2) CONNECTOR COMPATIBLE WITH ALL MODERN EVS SOLD IN EUROPE AND THE UK. THREE LEADING PRODUCTS WIDELY SPECIFIED FOR LONDON RESIDENTIAL INSTALLATION IN 2024-2025.

OHME HOME PRO 7.4KW (OHME ENERGY LTD — LONDON — THE LEADING SMART EV CHARGER BRAND IN THE UK RESIDENTIAL MARKET 2024-2025): 7.4KW (32A SINGLE-PHASE). SMART CHARGING FEATURES: CONNECTS TO OCTOPUS ENERGY, BRITISH GAS, AND OTHER MAJOR UK ENERGY SUPPLIERS DIRECTLY VIA API — THE OHME CHARGER AUTOMATICALLY ADJUSTS CHARGING RATE AND SCHEDULE TO TAKE ADVANTAGE OF CHEAP OVERNIGHT RATES (E.G., OCTOPUS GO: 7.5P/KWH OVERNIGHT 23:30-05:30 VS STANDARD RATE 28-30P/KWH) WITHOUT THE USER NEEDING TO SCHEDULE MANUALLY — THE CHARGER READS THE ENERGY SUPPLIER'S SMART TARIFF RATES IN REAL TIME AND OPTIMISES CHARGING TO MINIMISE COST. CABLE: TETHERED 7.5M TYPE 2 CABLE (ATTACHED TO THE UNIT — THE MOST CONVENIENT FORM FOR DAILY USE — THE DRIVER DOES NOT NEED TO CARRY OR STORE A SEPARATE CHARGING CABLE). SOLAR INTEGRATION: OHME HOME PRO INTEGRATES WITH SOLAR PV GENERATION DATA — AUTOMATICALLY BOOSTS CHARGING WHEN SOLAR EXPORT IS AVAILABLE (REDUCES EXPORT, INCREASES SELF-CONSUMPTION OF SOLAR).

WALLBOX PULSAR PLUS 7.4KW (WALLBOX CHARGERS SL — BARCELONA — ONE OF THE LEADING EUROPEAN EV CHARGING BRANDS): 7.4KW (32A SINGLE-PHASE). COMPACT DESIGN (ONE OF THE SMALLEST 7KW CHARGERS ON THE MARKET — 13.3X13.3X8.4CM — DISCRETE INSTALLATION). SMART CHARGING: WALLBOX APP (IOS, ANDROID) + WIFI/BLUETOOTH — SCHEDULE, SMART CHARGING, POWER SHARING (LOAD BALANCING BETWEEN TWO CHARGERS FOR A PROPERTY WITH TWO EVS). TETHERED OR UNTETHERED OPTIONS. IP54 (INDOOR OR SHELTERED OUTDOOR INSTALLATION ONLY — LESS WEATHERPROOF THAN IP65 UNITS — LESS SUITABLE FOR UNSHELTERED EXTERNAL WALLS IN LONDON'S CLIMATE). PRICE: £350-450 (SUPPLY ONLY). OZEV APPROVED.

THE OFFICE FOR ZERO EMISSION VEHICLES (OZEV — A UK GOVERNMENT OFFICE WITHIN THE DEPARTMENT FOR TRANSPORT) OPERATES THE DOMESTIC EV CHARGEPOINT GRANT — A GRANT OF £350 TOWARD THE COST OF A DOMESTIC EV CHARGEPOINT INSTALLATION FOR ELIGIBLE HOMEOWNERS AND RENTERS WITH OFF-STREET PARKING.

ELIGIBILITY FOR THE DOMESTIC EV CHARGEPOINT GRANT (2025): THE PROPERTY MUST HAVE DEDICATED OFF-STREET PARKING (A DRIVEWAY, GARAGE, OR PARKING SPACE ASSOCIATED WITH THE PROPERTY — NOT A PUBLIC CAR PARK OR SHARED ON-STREET PARKING). THE CHARGEPOINT MUST BE INSTALLED BY AN OZEV-APPROVED INSTALLER (A LIST OF APPROVED INSTALLERS IS MAINTAINED BY OZEV — ALL REPUTABLE HOME EV CHARGING COMPANIES — OHME, ZAPPI/MYENERGI, POD POINT, ROLEC, ANDERSEN EV, ETC. — HAVE THEIR STANDARD INSTALLATION PRODUCT APPROVED). THE CHARGEPOINT MUST BE FROM THE OZEV-APPROVED PRODUCT LIST. THE APPLICANT MUST BE A HOMEOWNER (OWNER-OCCUPIER OR PRIVATE LANDLORD) OR A PRIVATE RENTER (WITH LANDLORD PERMISSION). THE APPLICANT MUST HAVE (OR BE ORDERING) AN ELECTRIC VEHICLE — A PLUG-IN HYBRID (PHEV) ALSO QUALIFIES.

GRANT VALUE: £350 MAXIMUM — PAID DIRECTLY TO THE INSTALLER (NOT TO THE HOMEOWNER AS A CASH PAYMENT) — THE INSTALLER DEDUCTS THE £350 FROM THE HOMEOWNER'S INSTALLATION INVOICE. THE £350 GRANT IS FIXED — NOT A PERCENTAGE OF THE INSTALLATION COST — SO IT REPRESENTS A LARGER PROPORTION OF THE TOTAL COST FOR A SIMPLE INSTALLATION (WHERE TOTAL COST IS £700-900) THAN FOR A MORE COMPLEX INSTALLATION (WHERE TOTAL COST MAY BE £1,200-2,000). IMPORTANT: FOR LONDON VICTORIAN TERRACES WITHOUT A DRIVEWAY (THE TYPICAL TERRACE PROPERTY IN INNER LONDON — WHERE THE FRONT GARDEN HAS BEEN PAVED OR WHERE THERE IS NO OFF-STREET PARKING AT ALL): THE OZEV DOMESTIC EV CHARGEPOINT GRANT IS NOT AVAILABLE (NO OFF-STREET PARKING). THE ALTERNATIVE FOR ON-STREET PARKING-ONLY PROPERTIES IN LONDON IS THE LOCAL AUTHORITY EV CHARGING INFRASTRUCTURE — KERB CHARGERS (UBITRICITY/SHELL RECHARGE) INSTALLED IN THE KERB OUTSIDE TERRACE PROPERTIES — AVAILABLE FROM SOME LONDON COUNCILS (RICHMOND, LAMBETH, KENSINGTON AND CHELSEA) BUT NOT YET UNIVERSAL. NOTE: UBITRICITY STREET CHARGERS CHARGE AT 5.5KW (NOT 7.4KW) AND REQUIRE A UBITRICITY SMART CHARGING CABLE (INCLUDED IN THE ANNUAL MEMBERSHIP FEE).

A 7.4KW EV CHARGER (32 AMPS AT 230V) IS A SIGNIFICANT ELECTRICAL LOAD — THE LARGEST SINGLE CONTINUOUS ELECTRICAL LOAD IN MOST RESIDENTIAL PROPERTIES (EXCEEDING A TYPICAL ELECTRIC SHOWER — 10.5KW OR 45A — ONLY IF AN ELECTRIC SHOWER IS ALSO PRESENT). THE ELECTRICAL INSTALLATION REQUIREMENTS FOR AN EV CHARGER IN A LONDON VICTORIAN TERRACE ARE AS FOLLOWS.

CONSUMER UNIT (FUSE BOARD) ASSESSMENT: EVERY HOME EV CHARGER INSTALLATION MUST BEGIN WITH AN ASSESSMENT OF THE EXISTING CONSUMER UNIT CAPACITY. IN A LONDON VICTORIAN TERRACE, THE CONSUMER UNIT MAY RANGE FROM: A RECENTLY INSTALLED 17TH OR 18TH EDITION DUAL-RCD CONSUMER UNIT (HAGER, SCHNEIDER, CRABTREE LOADSTAR, WYLEX NH SERIES) WITH A 100A MAIN FUSE (SERVICE FUSE — SUPPLIED BY THE DNO — DISTRIBUTION NETWORK OPERATOR — UK POWER NETWORKS IN LONDON) — IN WHICH CASE A 32A EV CHARGER CIRCUIT CAN TYPICALLY BE ADDED WITHOUT A CONSUMER UNIT UPGRADE. AN OLDER WYLEX REWIREABLE CONSUMER UNIT (PRE-1990) — WHICH MUST BE REPLACED WITH A CURRENT 18TH EDITION DUAL-RCD UNIT BEFORE AN EV CHARGER CIRCUIT CAN BE ADDED. A BS 3036 (REWIREABLE FUSE) OR BS 1361 (CARTRIDGE FUSE) BOARD — ALSO REQUIRES REPLACEMENT. 18TH EDITION CONSUMER UNIT REPLACEMENT COST IN LONDON (2025): £400-700 (SUPPLY AND FIT — BY NICEIC/ELECSA REGISTERED ELECTRICIAN — INCLUDING NEW RCBO CIRCUITS FOR ALL EXISTING CIRCUITS AND THE NEW EV CHARGER CIRCUIT).

CABLE RUN FROM CONSUMER UNIT TO CHARGER LOCATION: THE EV CHARGER IS TYPICALLY LOCATED ON AN EXTERNAL WALL OF THE PROPERTY (ADJACENT TO THE PARKING SPACE OR GARAGE) — IN A LONDON VICTORIAN TERRACE: COMMONLY ON THE FRONT WALL OF THE PROPERTY (WHERE THE FRONT GARDEN HAS BEEN PAVED FOR PARKING) OR IN THE GARAGE (IF A SEPARATE GARAGE EXISTS AT THE REAR). THE CABLE RUN FROM THE CONSUMER UNIT TO THE CHARGER IS THE MAIN VARIABLE IN INSTALLATION COST: A SHORT CABLE RUN (CONSUMER UNIT IN THE HALL — CHARGER ON THE FRONT EXTERNAL WALL — 3-5M): SIMPLE AND CHEAP. A LONG CABLE RUN (CONSUMER UNIT IN THE KITCHEN AT THE REAR — CHARGER ON THE FRONT EXTERNAL WALL — 15-25M THROUGH THE PROPERTY): SIGNIFICANTLY MORE EXPENSIVE (MORE CABLE, MORE LABOUR, POSSIBLE NEED TO CHASE WALLS OR RUN THROUGH FLOOR VOIDS). CABLE SPECIFICATION: MINIMUM 6MM² TWIN AND EARTH (T+E) ARMOURED CABLE (SWA — STEEL WIRE ARMOURED — FOR UNDERGROUND RUNS TO A GARAGE OR FRONT GARDEN PARKING SPACE) OR 6MM² T+E IN CONDUIT (FOR SURFACE OR CONCEALED RUNS ON THE BUILDING). THE CABLE MUST BE PROTECTED BY A 32A RCBO (RESIDUAL CURRENT CIRCUIT BREAKER WITH OVERCURRENT PROTECTION — TYPE B OR TYPE A — THE OCPD SPECIFICATION FOR EV CHARGER CIRCUITS) IN THE CONSUMER UNIT.

HOME EV CHARGER INSTALLATION IN A LONDON RESIDENTIAL PROPERTY IS SUBJECT TO PART P OF THE BUILDING REGULATIONS (ELECTRICAL SAFETY — DWELLINGS) AND THE OZEV APPROVED INSTALLER REQUIREMENTS.

PART P (BUILDING REGULATIONS — ELECTRICAL SAFETY — DWELLINGS): THE INSTALLATION OF AN EV CHARGER IS A NOTIFIABLE ELECTRICAL INSTALLATION UNDER PART P — BECAUSE IT INVOLVES: THE ADDITION OF A NEW CIRCUIT TO THE CONSUMER UNIT (WHICH IS SPECIFICALLY LISTED AS A NOTIFIABLE INSTALLATION IN PART P). INSTALLATION OF ELECTRICAL EQUIPMENT IN A SPECIAL LOCATION (THE EXTERIOR OF THE BUILDING — PART P APPENDIX B). THE INSTALLER MUST EITHER BE A REGISTERED COMPETENT PERSON (NICEIC, NAPIT, ELECSA, OR OTHER PART P RECOGNISED SCHEME) WHO CAN SELF-CERTIFY THE INSTALLATION WITHOUT INVOLVING BUILDING CONTROL — OR MUST NOTIFY BUILDING CONTROL AND HAVE AN ELECTRICAL INSPECTION CONDITION REPORT (EICR) ISSUED BY A REGISTERED ELECTRICIAN AFTER INSTALLATION. IN PRACTICE: ALL OZEV-APPROVED EV CHARGING INSTALLERS ARE ALSO PART P REGISTERED ELECTRICIANS — THESE REQUIREMENTS ARE BUNDLED IN PRACTICE FOR HOME EV CHARGER INSTALLATION. THE INSTALLER ISSUES: AN ELECTRICAL INSTALLATION CERTIFICATE (EIC) CONFIRMING COMPLIANCE WITH BS 7671 (THE IET WIRING REGULATIONS — 18TH EDITION + AMENDMENTS). AN OZEV INSTALLATION CERTIFICATE (FOR GRANT CLAIM PURPOSES). CHARGING STANDARD: ALL EV CHARGERS INSTALLED IN THE UK MUST BE SMART-READY (CAPABLE OF SCHEDULING AND REMOTE COMMUNICATION) UNDER THE ELECTRIC VEHICLES (SMART CHARGE POINTS) REGULATIONS 2021 — THIS MEANS THAT NON-SMART CHARGERS (WITHOUT APP CONTROL OR SCHEDULE CAPABILITY) CANNOT BE SOLD OR INSTALLED IN THE UK FOR RESIDENTIAL USE FROM 30 JUNE 2022. IN PRACTICE ALL MAJOR BRANDED CHARGERS (OHME, ZAPPI, POD POINT, ROLEC, ANDERSEN) ARE ALREADY SMART-READY.

THE CHOICE BETWEEN A TETHERED EV CHARGER (WITH A PERMANENTLY ATTACHED CHARGING CABLE) AND AN UNTETHERED CHARGER (WITH A SOCKET OUTLET INTO WHICH THE DRIVER PLUGS THEIR OWN CHARGING CABLE) IS ONE OF THE MAIN PRACTICAL DECISIONS FOR A LONDON HOME EV CHARGER INSTALLATION.

TETHERED CHARGER (CHARGING CABLE PERMANENTLY ATTACHED TO THE UNIT): ADVANTAGES: MAXIMUM CONVENIENCE — THE DRIVER SIMPLY TAKES THE CABLE END FROM THE CHARGER AND PLUGS IT INTO THE VEHICLE — NO NEED TO CARRY OR STORE A SEPARATE CABLE. NO RISK OF THE WRONG CABLE BEING USED (THE INSTALLED CABLE IS THE CORRECT SPECIFICATION — 32A TYPE 2 — FOR THE CHARGER). DISADVANTAGES: IF THE CABLE IS DAMAGED (E.G., DRIVEN OVER OR CAUGHT IN A VEHICLE DOOR), THE CABLE MUST BE REPLACED BY THE INSTALLER (AT COST — TYPICALLY £60-120 FOR A REPLACEMENT CABLE) — THE USER CANNOT SIMPLY BUY A REPLACEMENT CABLE THEMSELVES AND PLUG IT IN. THE CABLE IS ALWAYS ATTACHED TO THE CHARGER — MUST BE COILED AND STORED ON THE CHARGER OR ON A CABLE HOOK WHEN NOT IN USE — CAN LOOK UNTIDY IF COILED ON THE UNIT. UNTETHERED CHARGER (TYPE 2 SOCKET OUTLET): THE CHARGER UNIT HAS A TYPE 2 SOCKET (IEC 62196-2) — THE DRIVER BRINGS THEIR OWN TYPE 2 TO TYPE 2 CABLE (OR THEIR CAR'S SUPPLIED CABLE) AND PLUGS IT INTO THE CHARGER. ADVANTAGES: THE DRIVER CAN ALSO USE THE CABLE WITH PUBLIC CHARGERS — ONE CABLE FOR BOTH HOME AND PUBLIC USE. IF THE CABLE IS DAMAGED, THE USER CAN BUY A REPLACEMENT CABLE THEMSELVES (APPROXIMATELY £30-80 FOR A SPARE 7.5M TYPE 2 CABLE). DISADVANTAGES: THE USER MUST STORE AND TRANSPORT A SEPARATE CABLE — MANY EV OWNERS FIND THIS INCONVENIENT FOR DAILY HOME CHARGING. THE USER MUST REMEMBER TO USE A 32A-RATED CABLE (NOT THE LOWER-RATED CABLE SUPPLIED WITH THE VEHICLE FOR GRANNY CHARGING — THE GRANNY CABLE IS TYPICALLY 8A OR 10A — INCOMPATIBLE WITH A 32A CHARGER'S FULL OUTPUT). RECOMMENDATION FOR LONDON HOME USE: TETHERED CHARGER IS THE MORE POPULAR CHOICE FOR PRIMARY HOME CHARGERS IN LONDON — THE CONVENIENCE OF NOT MANAGING A SEPARATE CABLE OUTWEIGHS THE SLIGHT INFLEXIBILITY. UNTETHERED IS PREFERRED WHERE: THE DRIVER HAS MULTIPLE EVS WITH DIFFERENT CONNECTOR STANDARDS (UNLIKELY IN A UK CONTEXT WHERE ALL CURRENT EVS USE TYPE 2); THE INSTALLATION IS IN A SHARED OR SEMI-PUBLIC SPACE WHERE MULTIPLE DRIVERS WITH THEIR OWN CABLES WILL USE THE CHARGER.
