It lovely @meldrewreborn here! So this survey tells us that most of the general population doesn't have a clue about energy costs, insulation costs and cost effective upgrades to homes. Of course if the household is renting they have little choice or involvement in the decisions. Even owner occupier of a leasehold flat don't have the ability to make many desirable changes, even if they wished to. I'm always wary of surveys like this because of the false premise that all of the population should know this stuff - its a fallacy.
Those home owners (a dubious phrase when many have large mortgages so really are only part owners) who pay attention to their bills for energy and take active steps to reduce them (like almost all of our top contributors) are very much in the minority. And when there is so much uncertainty about installing electric heat pumps (under the current EPC regime they would probably lead to a worse rating than the same property with a gas boiler) its not surprising that many are not eager to install them - particularly when electricity is almost 5 times the unit price of gas.
As in my own case, even moving from a 35 year old gas boiler to a new more efficient condensing gas boiler isn't worth it in financial terms, so people will stick to what they have until the boiler expires due to non availability of spare parts. Then and only then will a decision on replacement have to be made. In the future electric heat pumps might be the only option (the decision on a cut off date is still in the air).
We are continuously reminded that there's a cost of living crisis. Many will not even consider home upgrades to cut running costs at the moment, and those that are more comfortable will only consider changes when they're pushed - and even then many really don't understand all the issues.
