Can anyone recommend a good central heating course ideally covering s and y plan, underfloor heating systems and maybe ground source???
By the way, has anyone done the NIC PV course? The lad I work for has just done it and said it was a total waste of time and money with roofers and kitchen fitters on the course!!
