Installing an EV charger at a Broadstairs Victorian villa, where the wall is 400mm thick and the meter is in the cellar.
The five-storey Broadstairs villa stock along Ramsgate Road, Belvedere Road, Dumpton Park Drive and the streets behind Louisa Bay was not built with a home charge point in mind. The meter is often in a cellar, the driveway is a strip of gravel behind an old iron gate, the front elevation is stuccoed and the whole terrace sits inside the Broadstairs Town Conservation Area. Getting a 7kW charger onto that house without butchering it is a job that rewards a survey.
This guide is the way I approach a first-visit EV job on Broadstairs villa stock. It is deliberately specific to the housing type. Semi-detached ex-council on the Northwood estate or Kingsgate 1960s bungalows are simpler in almost every dimension; the villa is where the questions cluster.
Step one: what the supply is, not what the charger is.
Before we choose a charger, we survey the incoming supply. On a Broadstairs villa I want to know:
- Main fuse rating. UK Power Networks (the DNO for Kent) fits 60A, 80A or 100A cutout fuses. Older villas commonly have 60A or 80A. A 7kW charger draws around 32A, so on a 60A cutout, load management (dynamic or timed) is essential to avoid tripping the whole house during simultaneous cooker, kettle and shower use.
- Meter tails and cutout condition. Older tails on Broadstairs villas are often 16mm undersized for modern demand, and split into upstairs/downstairs sub-mains. UK Power Networks will not upsize the cutout without seeing tails to match.
- Earthing arrangement. TN-C-S (PME) is the most common modern arrangement, but a lot of older Broadstairs supplies are still TN-S (separate earth). Some outlying North Foreland properties are TT (earth rod). The arrangement decides whether the charger's own PEN fault detection is enough or whether we need a separate earth electrode outside.
- Consumer unit. If it is a Wylex rewireable or a plastic single-RCD board, the charger's dedicated circuit either needs its own metal enclosure adjacent, or the CU comes out at the same time.
Why the main fuse matters more than the charger spec.
A 7kW charger on a 60A supply is fine most of the time. Add an induction hob at 32A, an electric shower at 40A and a kettle at 13A and the maths does not add up. The chargers I fit for Broadstairs villas (Zappi, Ohme Home Pro, Wallbox Pulsar Plus) all support dynamic load management via a CT clamp on the tails, which throttles the charger when the whole-house demand climbs. That is what protects the DNO fuse without upgrading the supply.
Step two: Type A vs Type B RCD, and the DC fault question.
BS 7671 Section 722 requires that DC fault currents at charging points are handled either by a Type B RCD upstream or by the charger's own integrated 6mA DC fault detection combined with a Type A RCD. Type B RCDs are expensive (three to four times the price of Type A) and physically larger, so in practice we choose a charger with integrated 6mA DC detection and use a Type A upstream. Most PME-compliant home chargers on the market today (Zappi, Ohme, Wallbox Pulsar Plus, Andersen A2, Hypervolt) have this built in.
Two exceptions where a Type B is still the right answer: shared installations on a single RCD with other loads (rare in a domestic Broadstairs villa but common in a converted-flats scenario), and older chargers being reused from a previous property. If the make/model does not have current CE/UKCA declaration for integrated 6mA DC detection, Type B goes in.
Step three: the cable route on a five-storey villa.
The meter on a Broadstairs villa is nearly always in the front cellar or the front hall cupboard. The driveway is at the front, one storey up, behind a low front wall and railings. The typical route is:
- Existing meter or new henley block adjacent, into a switch-fuse or the CU depending on layout.
- 6mm twin-and-earth PVC through the cellar to the base of the front wall.
- Transition to 6mm SWA (steel-wire armoured) through the wall for external run.
- SWA up behind planting or clipped to the wall using stainless P-clips at 300mm centres.
- Into a weatherproof enclosure at the back of the charger, gland-terminated.
Total cable run on a Broadstairs villa is commonly 8-14m, well within the volt-drop budget for a 32A load on 6mm cable. Where the driveway is further back (a rear-access mews-type conversion off Serene Place or the North Foreland), 10mm cable comes in and the mounting position shifts.
Step four: listed and conservation-area detail.
A large chunk of central Broadstairs sits inside the Broadstairs Town Conservation Area or the St Peter's Conservation Area, both administered by Thanet District Council. Some individual villas along Chandos Square, Victoria Parade and Fort Road are listed. Article 4 directions apply in pockets.
An EV charger is normally permitted development under Class D of Schedule 2 Part 14 to the GPDO 2015, so long as the surface area of the wall-mounted unit does not exceed 0.2 square metres, the height does not exceed 1.6m above ground, and it is not within 2m of the highway. Class D still applies inside a CA, though Article 4 can lift permitted development. On a listed building, listed-building consent is a separate question from planning and is required for any external fixing that affects character.
Practical outcome: on a listed Broadstairs villa I plan the mounting position off the principal elevation (usually to a side or rear return where the wall meets a low garden wall), use recessed rear-entry so no external SWA is visible in the main sight-lines, and choose stainless-steel fixings drilled into mortar joints rather than the face brick or stucco. Where an Article 4 has been made, I ask the owner to check with Thanet DC planning before committing to the position. Thanet DC's planning duty officer takes short questions on this at no charge.
Step five: DNO notification and commissioning.
Every EV charger installation requires notification to UK Power Networks. For a single 7kW unit the ENA G100 process applies, and the notification is submitted online through the Energy Networks Association portal. Confirmation is typically returned within a few days. The Part P notification to Thanet DC goes through the competent-person scheme at the same time, so the owner gets a Building Regulations compliance certificate through the post.
On the day of commissioning I test to Section 722 of BS 7671: continuity, insulation resistance, polarity, earth-fault loop impedance at the vehicle connector, RCD trip times (both AC and DC-side), and confirm the charger's own tests (charging state simulation, cable check, PEN fault detection). The electrical installation certificate lists it all and the owner gets it as a PDF.
A good home charger install is invisible from the pavement, quiet at 3am, and does not touch the DNO fuse when the shower is on. Get the load survey right and everything downstream is straightforward.
