Tesla Referral Code & UK Delivery: The Questions People Actually Ask

Most of the confusion around Tesla referrals in the UK isn't about the reward itself — it's about timing, and what does or doesn't carry over once an order's in motion. Here are the questions we actually see, answered plainly, with sources.
Can I add a referral code after I've already ordered my Tesla in the UK?
No. Once the order fee is paid, a code can't be added or swapped in, and it can't be applied retroactively after delivery. It has to be attached before you pay — click the link first, then configure.
Does using a referral code change or delay my delivery date?
No. Allocation and build scheduling run on production and location, not on whether an order carries a referral code. The code only affects whether the 650 free Supercharging miles are added — it has no effect on the timeline.
What if my delivery date slips past when I expected the miles to land?
No issue. The 650 miles are tied to handover, not a calendar date, so a slipped delivery date doesn't forfeit the benefit — it lands whenever the car is actually handed over, provided the referral was attached at order time.
Can I use a referral code on an inventory (used/ex-demo) Tesla in the UK?
Yes, but the benefit differs: inventory cars carry a £500 discount rather than free Supercharging miles. That's specific to inventory stock, not new custom orders.
Does a referral code get me free Full Self-Driving in the UK?
No. FSD (Supervised) isn't road-legal or generally available in the UK yet, so there's no FSD trial for a UK referral to unlock. The UK benefit is Supercharging miles only — a site promising 'free FSD' here is quoting the US programme.
How many referrals can one Tesla owner give in the UK?
Tesla caps referrer rewards at 10 successful referrals per calendar year, with Supercharging credits expiring 12 months from grant (extendable up to 36 months as new referrals land). The buyer-side 650-mile benefit isn't capped, since it's tied to the order, not the referrer.
Is there a UK grant that stacks with the Tesla referral?
Not through Tesla directly. Two GOV.UK schemes exist alongside it: the EV chargepoint grant (up to £350 off a home charger install) and the newer Electric Car Grant (up to £3,750, restricted to EVs under roughly £37,000 — no current Tesla qualifies). Both run on GOV.UK's own process.
The one rule underneath all of this
Every answer above traces back to one mechanic: a UK referral attaches the moment you click the link, before you configure and pay. Nothing afterwards — allocation, build progress, a slipped estimate — can add, remove or change it. Get that click right and the 650 miles landing at handover takes care of itself.
