No, that is not the advice AT ALL.

Do not use flat surfaces at all - the RSPB issued advice against bird tables and stopped selling them a while ago. This applies to any flat surfaces, roofs etc
Do not feed seeds or nuts in feeders from May. This is because the birds at most risk eat these foods.
Small amounts of suet - that will be eaten in one or two days- is ok. Its fine to do this in feeders but clean the feeders with disinfectant every few days. The birds are risk largely don't eat suet.
Move feeders around and clean food and droppings underneath them.
Change water and clean out containers and bird baths daily.
Most of this is strengthened existing advice apart from the no seeds in feeders from May.
