2 minutes for tap water to come up to temperature in a new build?

As I said, I'd be astonished if it was this as it's so obvious...

(snigger :-). )

Best to keep in Eco mode, from the last debate I think it was decided it was very wastefull, even more at today's prices

Water vs gas. Which to waste?

At current (and future) prices, I guess water :-(

2 minutes is a VERY long time, tho'. 20 litres minimum each time? 4+ gallons? (Unless the tap is restricted - 'eco' - flow too...)

OP, suggest they at least capture that water and store it for garden use, car washing, etc.

You can safely wash hands in the 15c or colder water its not really wasted if you just use it.

The bathroom taps at my dad's takes minutes to get hot but the hot pipe does takes a very circuitous route to get there so not that surprising, if I'm having a shower, for example, I let the hot tap run first to get it to temperature. Whereas in my house the bathroom is directly above the boiler so the hot water is fairly instant, albeit seconds rather than minutes to get hot.

As mentioned, a lot depends on the flow rate of the boiler and the cold water mains pressure. If you have high pressure and a low flow rate then having the hot tap fully open will take longer to get hot so you may want to close the tap slightly to reduce the flow demand and give the boiler a chance.

Also if the heating is not on it will take longer for hot water.

Why would that be?
If anything I would expect it to be fractionally quicker if the heat exchanger is already hot.

I think that's what IDGWIAT said.
