I've had a response:
We’ve made the decision to reintroduce bagless shopping to support our plan to reduce the use of plastic at Tesco. We’re committed to reducing plastic and packaging wherever we can and we’ve already removed single-use carrier bags from our stores, as well as looking at other ways we can be more environmentally friendly.
We've included extra delivery time at the door for bagless orders. We know it can take longer and it's a new adjustment for lots of customers, so we want you to know there's no pressure to rush your unpacking.
We recommend having your own bags or boxes ready at the door to pack into. If you've not got these at the door, don't worry, there's always time to grab them.
Please be assured that we have very strict health and safety processes in place in our stores and our supply chain. Our delivery drivers continue to follow social distancing guidelines, so they'll deliver to your doorstep while keeping a 2‐metre distance from you.
If you need any extra help when receiving your order at the door, please put this in the delivery notes when checking out your order on our website. If you're vulnerable, disabled or elderly, and you're not self-isolating, the driver can bring your shopping into your home if you ask them.
Thank you again for taking the time to get in touch.
Kind regards,

Make of that what you will ladies! It seems we have to accept that this is what they are doing from 19 April.
