The 2026 Beginner’s Guide to the Nectar-Avios Merry-Go-Round

If you want cheap Avios in April 2026, you need to look at your Sainsbury’s receipts. The Nectar-Avios partnership is currently running a rare two-way transfer bonus, dropping the cost of buying British Airways points to a staggering 0.66p each.

We call this the “Merry-Go-Round” because you can ping points back and forth between the supermarket and the airline. Back before the 2024 devaluation, doing this was highly lucrative. Today, the standard rates are lopsided, meaning you lose 37.5% of your value if you do a full round-trip transfer. But as a one-way street for buying cheap Avios, it remains unbeatable.

Here is exactly how the maths works right now, and why you should probably move your points before the end of the month.

How the Nectar to Avios transfer actually works

You can link your British Airways Executive Club account to your Nectar account to swap points between the two programs.

The standard rate is simple: 400 Nectar points become 250 Avios. Because 400 Nectar points offset exactly £2.00 at the till in Sainsbury’s or Argos, you are giving up £2 of cash value to get 250 Avios. That means you are effectively buying Avios for 0.8p each.

Even without a promotion, this is the cheapest way to acquire Avios in 2026. Buying them directly from British Airways usually costs over 1.1p, even during a 50% bonus sale. If you want to fly in Club World, sourcing your points via your grocery shop is the most reliable strategy available.

Dealing with British Airways IT delays

Transfers are supposed to be instant. In practice, British Airways operates on notoriously fragile IT systems. Sometimes a transfer takes up to 24 hours to clear. Never wait until you see a reward seat sitting in your basket to initiate a transfer. The seat will almost certainly vanish before your Nectar points show up.

The April 2026 Easter transfer bonus explained

Right now, British Airways and Nectar are running a 20% bonus in both directions, completely changing the maths for April 2026.

If you send Nectar points to Avios before the end of the month, 400 Nectar points will yield 300 Avios. This drops your acquisition cost to 0.66p per Avios. I cannot stress enough how good this rate is. If you have a stash of Nectar points sitting around, this is the exact moment to move them across.

British Airways enforces a strict limit on these transfers. You are capped at moving 80,000 Nectar points per calendar month. Pushing that limit right now would net you 60,000 Avios for £400 worth of grocery points. That is enough for a one-way business class flight to Dubai.

Why you should turn off auto-convert immediately

Leaving your Nectar account set to automatically convert into Avios strips you of flexibility and leaves your points vulnerable to airline devaluations.

British Airways actively encourages you to toggle on auto-convert. Ignore them. Nectar points are a stable currency pegged to cash. Avios are subject to sudden chart changes and hidden fee hikes. Keep your balance safely parked in Nectar until you are ready to book a specific reward flight. When a promotion like the April 2026 bonus appears, you can manually push your points across and reap the extra 20%.

Does cashing out Avios for groceries make sense?

Converting your Avios into Nectar points to pay for your weekly shop is usually a terrible idea.

The standard rate going backwards is punishing. You trade 400 Avios for 400 Nectar points. That gives your Avios a hard cash-out floor of exactly 0.5p each. You should always aim to get at least 1p of value when redeeming for flights.

Even with the current Easter bonus pushing that floor to 0.6p, honestly, I’m not convinced the maths works for most people. The only exception is if you have a tiny, orphaned Avios balance you know you will never use for a flight. In that scenario, cashing out for a free lunch at Sainsbury’s is better than letting them expire.

Stopping your Avios balance from expiring

You can instantly reset the 36-month expiration clock on your entire British Airways balance by moving a tiny handful of points between Nectar and Avios.

Post-pandemic flyers are increasingly hitting that three-year deadline. If your account goes dormant, British Airways will wipe your balance. A simple 400-point manual transfer in either direction counts as qualifying activity. It costs you basically nothing and instantly secures your points for another 36 months.

The Amex Gold double-dip strategy

You can double your earning rate at Sainsbury’s by paying with an American Express Preferred Rewards Gold card while scanning your Nectar card.

This is a classic tactic we talk about frequently on Points Uncovered. The Amex Gold earns 1 Membership Rewards point per £1 spent, which converts instantly to 1 Avios. By scanning your Nectar card at the till, you pick up an extra 1 Nectar point per £1.

Let’s run the numbers on a £400 grocery shop during the current April promotion. You earn 400 Membership Rewards points (400 Avios) plus 400 Nectar points (converted to 300 Avios). That is 700 Avios on a standard weekly shop. Over a year, this completely changes your earning trajectory.

How to pool points with a partner

You cannot directly transfer your Nectar points to a partner’s Avios account. The name and date of birth on the Nectar account must match the British Airways Executive Club account exactly. If you want to pool points, you must transfer them to your own BA account first. Once they clear, you can share them using a standard BA Household Account.

The Points Uncovered verdict

The Nectar-Avios partnership remains the most reliable lever UK points collectors have in 2026, provided you manage your balances manually.

The days of pinging points back and forth without penalty are over. But as a method for securing cheap Avios, it is exceptional. The current 0.66p rate is spectacular. Move your points before the Easter promotion ends, keep auto-convert switched off, and remember to use a BA Household Account if you need to pool points with a partner.
