Any gas is better than no gas!
Lower octane will not cause permanent damage to modern engines - they have advanced knock detection and will pull timing to prevent pre-detonation. It will impact performance somewhat.
Especially if you only run one tank full of low-octane - I have had to do this once, no ill effects - just kept my foot out of it till I refilled with 93 octane.
Take care,

Terrible what is going on out West (to the UK), I suspect a sign of more to come unfortunately.
Running 98/99 Octane in the UK - you cannot even buy as low as 93 (95 is normal), never mind less!

The basis for the pump stamp is different in the UK as compared to the US. From Wikipedia:
https://en.wikipedia.org/wiki/Octane_rating
"Anti-Knock Index (AKI) or (R+M)/2
In most countries, including Australia, New Zealand and all of those in Europe,[citation needed] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2. It may also sometimes be called the Posted Octane Number (PON).
Difference between RON, MON, and AKI
Because of the 8 to 12 octane number difference between RON and MON noted above, the AKI shown in Canada and the United States is 4 to 6 octane numbers lower than elsewhere in the world for the same fuel. This difference between RON and MON is known as the fuel's Sensitivity,[4] and is not typically published for those countries that use the Anti-Knock Index labelling system."
For example:
UK std unleaded "95"octane = is what they call 90/91 octane in the USA
UK "super" "97/99"octane = is what they call 92 /93 octane in the USA
