For the vast majority of UK homeowners, installing a home EV charger is permitted development — meaning no planning application is needed. But Cornwall has more listed buildings and conservation areas than almost any other county, and the exceptions catch people out. Here's the 2026 rule set, the Cornwall-specific gotchas, and the parallel question that does always apply: Building Regulations approval.

Permitted development — the default position

Per the Town and Country Planning (General Permitted Development) Order 2015 (as amended), you do not need planning permission to install an EV chargepoint on a residential property in England, provided:

  • The chargepoint is mounted on a wall or installed within the curtilage of a dwellinghouse
  • A wall-mounted unit is no more than 0.2 cubic metres in volume (well within any standard home charger)
  • A free-standing pedestal charger is no more than 2.3 metres in height
  • The chargepoint is not within 2 metres of a public highway (including the pavement)
  • The property is not a listed building
  • The property is not in a conservation area or article 4 area with restrictions specifically affecting EV chargers

If all six conditions are met, you can install without planning consent. The installer handles the work; you just pay.

When permitted development doesn't apply

Listed buildings

Listed building consent is required for almost any external work. Cornwall has roughly 12,000+ listed buildings (one of the highest counts in England). If your property is Grade I, II*, or II listed, you need listed building consent from Cornwall Council before installing any EV charger that's visible from public view. The application is free; the wait is typically 8-12 weeks.

Check your property's listed status via the Historic England National Heritage List (historicengland.org.uk) or via Cornwall Council's planning portal.

Conservation areas

Cornwall has dozens of conservation areas. Major ones include:

  • Padstow (whole town centre)
  • Mevagissey (harbour area)
  • Falmouth (Old Quay, Custom House Quay areas)
  • St Ives (Downalong, harbour)
  • Penzance (much of the town centre and Chapel Street)
  • Polperro (the whole village)
  • Truro (cathedral close, Lemon Quay surroundings)
  • Looe (East and West Looe waterfronts)
  • Plus 40+ smaller designations

Within a conservation area, permitted development is restricted. For an EV charger:

  • If the charger is at the front of the property (visible from the highway), you almost certainly need planning permission
  • If the charger is at the rear (not visible from public), permitted development usually applies — but check with Cornwall Council to be safe
  • Article 4 directions can override permitted development; conservation officers will confirm

Within 2 metres of a public highway

The 2-metre rule is the most common trip-hazard. If your driveway sits directly against the pavement and the charger would be within 2m, you need planning permission. This is more common in terraced street layouts (St Just, Camborne, Hayle, Newlyn).

Pedestal chargers over 2.3 metres tall

Standard wall-mount: no issue. Free-standing pedestal: usually well under 2.3m. The rule mainly catches commercial-grade pedestals occasionally fitted at residential properties.

Building Regulations — always required

Separate from planning permission, Building Regulations approval is always required for EV charger installation. The work creates a new electrical circuit, which is "notifiable work" under Part P of the Building Regulations.

This doesn't mean you submit a building control application yourself — it means the work must be done by a competent person registered with a scheme (NICEIC, NAPIT, ELECSA, Stroma, etc.) who can self-certify on completion. They issue you a compliance certificate within 30 days; you keep it for the life of the installation (and any future house sale).

  • Modern OZEV-approved installers handle this automatically
  • The certificate covers compliance with BS 7671:2018+A2:2022 Section 722 (EV charging installations)
  • You'll need this certificate for warranty claims and for the standard property information form when you sell

What about Part S?

Part S of the Building Regulations (introduced 2022) requires new-build residential properties and certain renovations to include EV charging infrastructure as standard. Part S doesn't normally apply to retrofitting a charger to an existing home — it applies to:

  • New-build homes
  • Major renovations creating new dwellings
  • Buildings undergoing change of use to residential
  • Mixed-use new-build and major renovation

If you're a developer or building a new home in Cornwall, your design must meet Part S charging-infrastructure requirements. If you're a homeowner retrofitting a charger to an existing house, Part S doesn't apply (but Part P does, see above).

How to check your property

  1. Check listed status: historicengland.org.uk - Search the List - enter address.
  2. Check conservation area / article 4: Cornwall Council planning portal (cornwall.gov.uk/planning) - property search.
  3. Measure to highway: stand at the proposed charger position; measure to the nearest edge of the public highway/pavement. Anything over 2m is fine.
  4. If unsure, pre-application advice: Cornwall Council offers a pre-application advice service for planning queries — small fee, quick response.

What if you need planning permission?

The application is straightforward:

  • Householder application: around £200 fee in 2026
  • Listed building consent: Free
  • Decision time: 8 weeks typical for householder; longer for listed
  • Documents needed: Site plan, elevation drawings showing charger location, brief description, photos. Your installer can usually help.
  • Conservation officer involvement: Likely; they'll suggest minimal-visual-impact solutions (matt black or off-white finishes, fitting at sides/rears of properties, etc.)

Refusals are rare for sensibly-placed chargers; most refusals relate to highly visible installations on prominent listed buildings.

Cornwall planning quirks

  • Granite walls — sometimes flagged in conservation reviews. Installers may need to use surface conduit or specific fixing methods. Discuss with conservation officer ahead of install.
  • Mevagissey, Polperro, and other narrow-lane villages — the 2-metre highway rule is very tight. Many properties' driveways start right at the lane edge. Check measurements carefully.
  • National Trust property lets — some Cornwall holiday cottages are NT-owned. Additional consent from NT is required regardless of planning status.
  • Cornwall AONB (Area of Outstanding Natural Beauty) — most of the Cornish coast. AONB designation strengthens the conservation case but doesn't generally remove permitted development for EV chargers on existing dwellings.

The bottom line

  • Modern detached home, off-road parking, no listed/conservation status: No planning needed; install and certify under Building Regs.
  • Conservation area, charger at rear (hidden from public): Usually no planning needed; confirm with Cornwall Council.
  • Conservation area, charger at front: Planning permission likely required.
  • Listed building: Listed building consent required, regardless of charger location.
  • Within 2m of highway: Planning permission required.
