Summary

Flat dwellers are the hardest group to serve with home EV charging. Unlike a house owner who controls their own property, a flat resident typically has no individual outdoor parking, no electrical supply at their parking space, and no right to install equipment in communal areas without freeholder consent. Even where all these obstacles are cleared, the communal electrical supply may have no capacity for additional EV loads.

For electricians, communal EV installations are a growing and rewarding market but require skills beyond standard domestic EV work: dealing with management companies, navigating the leasehold system, designing shared metering and billing infrastructure, and understanding building regulations for existing residential blocks.

This article covers the practical, legal, and technical landscape for EV charging in existing and new residential blocks.

Key Facts

  • Leasehold consent — leaseholders typically cannot install in communal areas without freeholder or management company consent; the lease must be checked for any charging-specific rights
  • Right to request — from June 2022, qualifying leaseholders have a right to request EV charging installation under the Building Safety Act 2022 reforms; landlord can refuse on limited grounds
  • Approved Document S (England) — mandates EV charging provision in new residential buildings (11+ residential units) with associated parking; also requires cable routes (ducting) in new buildings for future fitting
  • Individual sub-metering — each charging point must be on a separate electricity account or sub-metered to enable fair cost allocation; communal supply cannot be shared without metering
  • OZEV EV Infrastructure Grant — residential blocks may qualify if there is associated car parking; up to 40 sockets, £350 per socket
  • LEVI (Local Electric Vehicle Infrastructure) Fund — government fund for EV charging in underserved locations including residential blocks; administered through local authorities and aggregators
  • Communal supply capacity — most existing residential blocks have limited supply headroom; large-scale EV charging typically requires a DNO supply upgrade
  • Cable routes through common parts — requires a wayleave or licence from the freeholder; may require asbestos surveys in older buildings before drilling
  • RCD protection — each chargepoint circuit must have a dedicated RCD/RCBO even in a communal system
  • Smart charging — all new chargepoints must comply with the Smart Charge Points Regulations 2021 regardless of residential context
  • Parking space ownership — some leaseholders own their parking space; others have a licence to use it; this affects rights to install hardware

Model How It Works Best For Key Challenge
Individual installs (house-style) Each flat installs its own chargepoint with its own dedicated circuit from the flat's meter Individual houses or private parking spaces; consent not an issue Supply capacity; routing cables
Shared communal system Single electrical feed to car park; sub-distribution board with individual metered circuits to each space Managed residential blocks Freeholder consent; metering; DNO capacity
Managed network (CPMS) Chargepoints connected to a network; residents use app/RFID; billing via network operator Large blocks; mixed resident/visitor use CPMS setup; ongoing management contract
Charge point operator (CPO) model CPO funds, installs, and manages the infrastructure; residents pay per kWh Sites with low initial capital Long-term contract; revenue sharing

Detailed Guidance

Legal Framework: Leasehold and Freeholder Consent

The standard position: Most residential leases contain a clause preventing leaseholders from making alterations to communal parts (car parks, cable routes through common areas, external walls) without the freeholder's written consent. This means a leaseholder cannot unilaterally run a cable from their flat to their parking space if the route passes through common parts.

Right to Request (from June 2022): The Leasehold Reform (Ground Rent) Act 2022 and associated secondary legislation introduced a qualified right for leaseholders to request EV charging installation. The landlord may refuse only on prescribed grounds (e.g., structural impossibility, listed building constraints, verified insufficient supply capacity). Where consent is refused unreasonably, the leaseholder may apply to the First-tier Tribunal (Property Chamber). This is a significant development but is not absolute — landlords retain legitimate grounds for refusal.

Freeholder as project lead: In most multi-unit blocks, the practical approach is for the freeholder or management company to project-manage a block-wide EV charging scheme, funded partly by OZEV grants and partly by residents. This approach resolves consent issues for all residents simultaneously and creates a managed communal infrastructure.

Metering and Billing Architecture

Individual fair billing is the central technical challenge. Options:

Option 1: Dedicated circuits from individual flat meters Each resident has their own dedicated 32A circuit from their flat consumer unit to their parking space. They pay for their own electricity on their own tariff. Most equitable, but:

  • Requires a cable route from each flat to its parking space (often not practical in large blocks)
  • Requires freeholder consent for each cable route through common parts
  • The supply may not have capacity for individual 32A circuits for every space

Option 2: Sub-distribution board with smart metering A single three-phase feed from the building's landlord supply (or a dedicated new supply) feeds a sub-distribution board in the car park. Individual metered circuits run to each chargepoint. An energy management system records energy consumption per circuit and bills residents separately (via the management company or a third-party billing service).

This is the standard approach for managed communal systems. The energy meter reads per-chargepoint consumption; the building management company bills each resident for their actual usage (monthly or quarterly).

Option 3: Network operator (CPMS) billing Chargepoints are connected to a charge point network (e.g., Pod Point, Zaptec, EO Hub). Residents authenticate via RFID or app and are billed directly by the network operator per kWh. The network operator typically charges the building a flat-rate per-unit electricity cost and marks it up to residents, or the building passes through the actual cost plus an admin fee.

This model requires minimal ongoing management from the freeholder but involves a long-term contract with the network operator and a markup on electricity costs for residents.

Supply Capacity Assessment

Existing residential blocks built before 2010 typically have:

  • Single-phase 100A per flat (landlord supply for communal lighting, lifts)
  • No dedicated supply for car park electrics

For even a modest 10-chargepoint installation at 7.4kW each, the theoretical maximum simultaneous load is 74kW — far exceeding most existing communal supplies. Load management reduces this in practice (not all residents charge simultaneously), but the supply infrastructure often still needs upgrading.

DNO engagement: A supply upgrade application to the DNO should be made early in the project programme. DNOs are aware of the residential EV challenge and have published connection policies for managed schemes. The LEVI fund can provide funding for DNO connection costs in certain cases.

Smart scheduling: For overnight residential charging, smart scheduling is highly effective. If all residents charge between midnight and 6am, the peak simultaneous demand is much lower than the theoretical maximum — vehicles can be queued and scheduled. A 100kVA supply could theoretically charge 30+ vehicles overnight if staggered. The Smart Charge Points Regulations 2021 require time-of-use scheduling, which makes this practical.

New Builds: Approved Document S

For new residential developments in England:

Requirements (in force from June 2022):

  • Residential buildings with 11+ dwellings and associated parking: at least 1 in 5 spaces must have a charge point; all other spaces must have cable routes (ducting) for future fitting
  • The charge point must be a Mode 3 smart chargepoint
  • Commercial buildings with 10+ car parking spaces: same 1-in-5 rule

This applies to new-build and material change of use. It does not retrospectively apply to existing buildings (though LEVI and grant funding may support retrofits).

Practical implication for electricians: On new-build residential projects, EV charging infrastructure is now a standard scope item — sub-distribution boards in car parks, conduit in floor slabs, and chargepoints for the qualifying spaces. Electricians on new-build residential should be familiar with AD S requirements.

Asbestos and Older Buildings

For cable routes through communal parts in residential blocks built before 2000:

  • An asbestos survey (Refurbishment and Demolition survey) is required before drilling or disturbing any building fabric that may contain asbestos
  • Asbestos cement was commonly used in roof panels, floor tiles, electrical duct liners, and internal panels in 1950s–1980s residential blocks
  • The management company or freeholder should have an existing asbestos register; request this before starting work
  • Where asbestos is present in the route, a licensed asbestos removal contractor must clear the route before the electrician works

Practical Approach: Block-Wide Scheme

A practical workflow for a block of 20 flats with communal car park:

  1. Appoint an EV charging consultant or experienced electrician to survey and design the scheme
  2. Engage the freeholder/management company — they must lead the consent process and DNO application
  3. Commission DNO supply assessment — confirm available headroom and upgrade cost
  4. Apply for OZEV EV Infrastructure Grant — up to 40 sockets, £350 each
  5. Contact LEVI fund via local authority — additional funding for supply infrastructure
  6. Design sub-board and metering architecture — typically a three-phase sub-board in the car park, individual metered circuits to each space
  7. Select CPMS platform — or manage billing through the management company with smart metering
  8. Phase the installation — start with the spaces where residents have current EVs; install conduit to all spaces for future expansion
  9. Obtain building control notification (EIC required for each circuit; no separate building control submission typically needed for EV chargepoints, but the wider supply works may require notification)

Frequently Asked Questions

Can a leaseholder install an EV chargepoint without freeholder consent?

Only if the installation is entirely within their demised premises (their flat and their dedicated parking space) and the cable route does not cross common parts. In most blocks, this is not possible — the cable must cross a communal corridor, stairwell, or car park floor. In those cases, freeholder or management company consent is required. Since June 2022, unreasonable refusal by a landlord can be challenged at the First-tier Tribunal.

What is the EO Hub and is it suitable for flats?

The EO Hub is a load-balancing system from EO Charging that allows multiple EO chargepoints to share a single supply, with individual metering per unit. It is well-suited to small-to-medium residential blocks (5–30 spaces) with a single communal electrical feed. Similar systems are available from Zaptec, Wallbox, and others.

Does an individual flat resident need planning permission for their chargepoint?

Where the chargepoint is in a private parking space outside the building (e.g., a detached house that happens to be in a block), planning is as per normal domestic PD rules. For communal car parks within the curtilage of the building, installation is generally PD for residential use. However, where the building is listed or in a conservation area, planning permission or listed building consent may be required.

Who pays for the communal supply upgrade?

In a managed freeholder-led scheme, the infrastructure cost is typically shared between the freeholder (who owns the common parts) and residents (as beneficiaries). Grant funding from OZEV and LEVI can significantly reduce the net cost. In practice, the resident contribution is often modest for OZEV-funded schemes.
