With EV charger installation quotes ranging from £500 to £2,000+, it's tempting to go for the cheapest option. But could a bargain installation cost you more in the long run?

The Price Spectrum

What You'll See

Price RangeWhat's Typical
£500–700Budget charger, basic installation, minimal extras
£800–1,100Mid-range charger, standard installation, some flexibility
£1,200–1,500Premium charger, thorough installation, professional finish
£1,500+Complex installation, premium charger, or specialist requirements

Why Prices Vary

Legitimate reasons for higher prices:

  • Better quality charger
  • More thorough installation
  • Proper assessment and planning
  • Quality materials
  • Experienced installers
  • Better warranties and aftercare
  • Red flags for very cheap prices:

  • Cutting corners on installation
  • Using uncertified installers
  • Poor quality charger units
  • Minimal assessment
  • Hidden extras to be billed later
  • What Makes a Quality Installation

    The Proper Process

    StageWhat Should Happen
    AssessmentFull survey, electrical capacity check, DNO check
    PlanningClear scope, itemised quote, timeline
    InstallationNeat cable runs, proper terminations, testing
    CertificationElectrical certificate, DNO notification
    HandoverDemonstration, paperwork, warranty registration

    Minimum Standards

    By law (Part P Building Regulations):

  • Installation by a competent person
  • Notification to building control (or Part P self-certification)
  • Electrical certificate (BS 7671 compliance)
  • By DNO requirement:

  • Installation notified to Distribution Network Operator
  • Some smart charger requirements
  • By manufacturer warranty:

  • Installation by approved/certified installer
  • Registration of the charger
  • Where Cheap Installs Cut Corners

    Corner #1: The Assessment

    Proper assessment:

  • Electrician visits property
  • Checks consumer unit capacity
  • Measures cable runs
  • Identifies potential complications
  • Provides accurate quote
  • Cheap approach:

  • Quote over the phone based on address
  • "Standard installation" assumed
  • Extras discovered (and billed) on the day
  • No check of electrical capacity
  • Risk: Unexpected costs on installation day, inadequate installation.

    Corner #2: The Charger Unit

    Quality chargers (£400–700):

  • Reputable brands (Ohme, Pod Point, Wallbox, etc.)
  • Full manufacturer warranty (3–5 years)
  • Regular software updates
  • Reliable smart features
  • Good build quality
  • Budget chargers (£200–350):

  • Unknown or lesser brands
  • Limited warranty (1 year, if any)
  • May lack smart features or reliability
  • Potentially discontinued products
  • Inconsistent build quality
  • Risk: Charger failure, lack of support, obsolescence.

    Corner #3: Cable and Materials

    Quality approach:

  • Correct cable gauge for distance
  • Proper outdoor-rated materials
  • IP65+ rated enclosures
  • UV-resistant cable protection
  • Corrosion-resistant fixings
  • Cheap approach:

  • Undersized cable
  • Indoor materials used outdoors
  • Minimal weatherproofing
  • Basic fixings that rust
  • Risk: Premature failure, safety issues, water ingress.

    Corner #4: The Installation Work

    Quality work:

  • Neat, concealed cable runs where possible
  • Proper cable clips at correct intervals
  • Cores correctly terminated
  • Charger level and secure
  • All connections tight and protected
  • Cheap work:

  • Visible, poorly routed cables
  • Loose fixings
  • Rushed terminations
  • Charger not properly secured
  • "It works, good enough" attitude
  • Risk: Unreliability, ugly appearance, potential safety issues.

    Corner #5: Consumer Unit Work

    Quality approach:

  • Proper assessment of consumer unit
  • Correct breaker and RCD/RCBO
  • Safe isolation during work
  • Neat, labelled installation
  • Certificate of compliance
  • Cheap approach:

  • Inadequate protection
  • Overcrowded consumer unit
  • Poor labelling
  • No certificate or substandard paperwork
  • Risk: Safety issues, insurance problems, fails future inspection.

    Corner #6: Testing and Certification

    Quality approach:

  • Full testing post-installation
  • Earth loop impedance checks
  • Insulation resistance tests
  • RCD trip time tests
  • Proper electrical certificate (Minor Works or EIC)
  • Cheap approach:

  • Minimal testing
  • "It switches on" = complete
  • Generic or missing certificate
  • No DNO notification
  • Risk: Undetected faults, no paperwork for sale/insurance, uncertified installation.

    Real-World Problems from Cheap Installs

    Problem 1: Charger Failure

    What happens: Budget charger fails after 18 months. Manufacturer has no UK support, warranty claims go nowhere.

    Cost: £400–700 replacement charger + £200–300 installation

    vs. quality install: Premium charger with 5-year warranty would have been repaired or replaced for free.

    Problem 2: Hidden Costs

    What happens: £600 quote turns into £1,200 when installer "discovers" consumer unit needs work, cable run is longer than expected, groundwork required.

    Result: More expensive than mid-range quote that included proper assessment.

    Problem 3: Water Ingress

    What happens: Outdoor-rated but poorly installed charger develops water ingress. Trips electrical supply repeatedly.

    Cost: Investigation + remedial work: £200–400. Potential charger replacement.

    Problem 4: Insurance Issues

    What happens: Electrical fire (unrelated to charger). Insurance investigator finds charger installation has no certificate. Claim complicated or refused.

    Risk: Invalidated insurance claim worth thousands.

    Problem 5: Selling the Property

    What happens: Buyer's solicitor requests electrical certificates. None available for charger installation. Delays or price negotiations.

    Cost: Remedial inspection + certification: £200–400. Potential price reduction.

    Problem 6: DNO Investigation

    What happens: Neighbourhood electrical issues lead DNO to check installations. Unnotified charger installation discovered. Required to rectify.

    Cost: Retrospective notification + any required upgrades.

    The Verdict

    Are cheap EV charger installs a false economy?

    Often, yes. The savings of £200–400 upfront can easily become £400–800 in extra costs when things go wrong. Plus the hassle, the uncertainty, and the potential safety and insurance implications.

    The sweet spot: A mid-range installation from a reputable local installer, with a quality charger and proper certification. This typically costs £900–1,200 — more than the cheapest quotes, but far better value in the long run.

    The rule: If a quote seems too cheap, it probably is. Electrical work isn't where you want to cut corners.
