How the Nectar ⇆ Avios Exchange Works
Link your Nectar and British Airways Club accounts (in the Nectar app or on ba.com) — transfers are then instant
Nectar to Avios: minimum 400 Nectar points, converted in multiples of 400
Avios to Nectar: minimum 250 Avios, converted in multiples of 250 — a guaranteed 0.8p per Avios at Sainsbury's, Argos and eBay
Tesco Clubcard converts via Clubcard Reward Partners in £2.50 voucher blocks
Nectar points are worth 0.5p each in store, so converting to Avios only wins if you redeem Avios at more than 0.8p — long-haul and premium-cabin reward flights usually beat this comfortably
