How this is worked out
Net install = quote − grant (if eligible). Annual saving = your yearly kWh × the gap between public and home rates. Payback = net install ÷ annual saving. The EV chargepoint grant is up to £350; homeowner eligibility largely ended, so check whether the renter/flat-owner scheme applies to you. Checked 2026-07-13. Source: GOV.UK EV chargepoint grants.
Questions
Can I still get a grant for a home Tesla charger in the UK?
The original homeowner grant (OZEV/EVHS) closed. The current EV chargepoint grant of up to £350 is mainly for people who rent, or who own a flat. Check the GOV.UK eligibility list before assuming you qualify.
How long does a home charger take to pay for itself?
It depends on the gap between your home rate and what you'd otherwise pay to charge publicly, and how many miles you drive. For an average driver switching from public charging, a few years is typical — the tool gives your own number.
