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.
How to Spot a Quality Installer
Good Signs

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.
