Presume regs have changed then, I built over simgle skin garage circa 1970 with full council approval. I used single skin blockwork with hanging tiles.

Gas £71.40p (one gas fire). Economy 7 Electric £283.70p (Immersion heater, 4 fan heaters, appliances). Total £355.10p.

I use a 110v circular saw but then had it out of a skip! It was ex hire company, only needed new carbon brushes, still going strong after 30+ years! 110v is safer voltage to work with hence it’s use on site but now being replaced by cordless!?
With respect you had the advantage of knowing that it had already been established that it wasn’t the MAP sensor at fault. A lot of main dealers would no doubt have also initially replaced the MAP sensor!?
