Sounds expensive to me. My house is approx 250m2 and DIY cost is coming in at around £3,000 (minus room valves)

 

For a house of your size, I'd seriously consider 2x units.

Seems very expensive to me.

 

Nearly three grand just for first fix ductwork labour? Without any previous experience, I installed all of my ducting (£289 m2 house) over an easy couple of days with occasional help from my wife. Even at £300 a day (which is a lot given it's a low-skill job), what are they doing for 10 human-days?


And what "second fix" works? Surely that's just fitting inlets and outlets? Again, how much time could that realistically take?
