OK we had a new boiler, and we have underfloor heating and we do not go upstairs during winter. Still Water, Gas, Electricity seem to be much cheaper than before (OK water a bit higher (no swimming and showers)m but Gas and electricity much cheaper than before. (Annual bill together well below EUR 1500) (very well). Somehow I expect a surcharge next year because I can not believe it is that low. (Not disclosing figures but total could also be below EUR 1000)
As for meat and fish, online ordering proved to be much more cost-effective than supermarkets (so we will probably continue this way). (BIG savings)
