An interesting question. Firstly, decisions of other tiers/authorities should have no bearing whatsoever on your precept planning. You should focus on your needs and plans and decide what is appropriate for your council.
Secondly, this is an opportunity for all those councils sitting on vast reserves for rainy days to loosen the purse strings. It's raining now, like no other time in living memory. A few years ago I inherited a council with a general reserve that equated to £150 per household and no spending plans. For some of those households, £150 would have been a life-changing sum. A year's expenditure is more than adequate, apart from specific reserves for projects.
Personally, I doubt whether things will look much better next Christmas than they do now. Whilst the vaccination programme should deal with the virus, Government interventions have merely delayed tens of thousands of job losses and evictions. For many, 2021 will be a worse year than 2020.
