Neighbours replaced warm air with boiler now spending more money

Warm air systems have the advantage of less plumbing and so less chance of leaks, scaling and corrosion but are best suited to smallish properties as the duct sizes become cumbersome in larger buildings and need to be allowed for early in the design process.

I would agree with that to some extent. I think warm air went out of "fashion" as the house had to be designed around it. A wet system can be stuck in any design.
There was obviously a cost penalty in the design/build of a warm air house, the fact that it might be cheaper to run was of no interest to the the house builder/seller !

Some neighbours, who changed their heating and go to work, have their heating on for an hour in the morning and 6 hours at night.

I used 18763 kWh of gas and some used 20121 kWh of gas in the past year. One only used 17325 kWh.

You don't know at what temperature they have the heating on and how much hot water they're using though.

I have a 20 year old gas boiler/radiators system, I'm in pretty much all day (work from home) and over the past 12 months I've used 7618 kWh of gas on heating/cooking/hot water... yet I'm using far less than many of my neighbours who are out all day, most of them have boilers which are newer than mine too.

Edit: I have nothing against warm air heating
