V2L Workshop
Using your EV as home backup — done safely, to BS 7671.
Plain, sourced UK guidance on running a small essential load from an electric vehicle’s V2L (vehicle-to-load) output — backup and scheduled load-shifting — for informed homeowners and qualified electricians. The hard part is the changeover and the earthing; that is what we explain, clause by clause.

Guides
Decision-journey guides: the plan most people try, why it's wrong, and the correct path.
Safety & earthing
Every UK earthing system explained — plus how to identify yours, and the floating-output problem.
Standards clause-index
Feature → standard → clause: the transparency map under every claim. Referenced, never reproduced.
V2L vehicle finder
Which EVs offer V2L, how much they deliver, and the safety-critical floating-vs-bonded output status.
V2L kit
The changeover, protection and earthing kit a competent person specifies — with honest disclosure.
Cost & payback
Will V2L load-shifting actually pay back? Model it honestly against a home battery — round-trip losses, battery wear and break-even spread included.
Our method & sources
How we source every claim, flag confidence, and gate anything not yet verified against the standard.
Why this site
The UK has a large EV base and a fast-moving bidirectional-charging market, but no single public source maps the BS 7671 clauses, the open-PEN/earthing logic, transfer-switch failure modes and the device data together — cited, dated and honest about uncertainty. That is the gap we fill. Information is the trust builder: where a claim is contested or not yet confirmed against the published standard, we say so rather than guess.
