Been issued a notice to quit?

We have a short ured tenancy in Scotland, and pay �900 a month for our 4 bedroom family home. When we moved in the landlord had left the double garage full to the brim, and a car in our driveway. He told us this would be removed in 2 days. It wasnt... it took three months for the car to be moved out of the driveway, and almost six months for the garage to be emptied. We have very small children and have spent the winter having to defrost our cars in the morning. We also waited two months for him to fix the fire, which still hasnt been fixed, and the shower in the ensuite bathroom was smalling of smoke, instead of fixing it he just turned the pump off, so now its got little water pressure. We spoke to a solicitor and our landlord and reducedour rent to �750 a month to push him to emptying the garage. When he still did not we withheld a months rent. After he emptied the garage we paid the rent, and then the next month restared �900 a month. He issued us with a notice to quit stating we hadnt paid enough rent, and were late on paying it! Will we be evicted? Our son has a chronic disease, our children are settled in the local schools, we have no where else to go. We were meant to be here for 2 years.
