What does the delay mean for work from home?

Is the advice still work from home where possible?

Yes, thankfully. From gov.uk:

"You should continue to work from home where you can.

If you cannot work from home you should continue to travel to your workplace. You do not need to be classed as a critical worker to go to work if you cannot work from home.

Employers and employees should discuss their working arrangements, and employers should take every possible step to facilitate their employees working from home, including providing suitable IT and equipment to enable remote working. "

It stays the same unfortunately. I'll carry on going in two or three days a week though as I'm likely to walk out if I have to go back to WFH home full time.
