Same happened to me about two weeks ago, £30 intrest charge they said it was

Hello Please could someone advise me on a few issuies at hand. The first one is: 1. In Feb my partner gave birth to my first baby (01/02/2008), unfortunately this happens to be the same date I deposit the rent into my landlord (Who is the agent aswell) although the rent is only due on the 3rd of the month, the 1st Feb was also a Friday. I did not manage to deposit the money in his account on the 1st as my partner went into labour @ 5:30am. I spent the whole day Saturday at the hospital and didnt manage (didnt remember) to deposit the rent till Wednesday 6th, the only thing that made me remember that i didnt deposit the money was a missed call (on the 6th) from the landlord's number.I ran quickly into town and deposited the money, called the landlord & apologised as I had alot on my plate.The land lord was fully aware that my partner was pregnant,infact they even knew that she had given birth BECAUSE the phoned her aunty and told her aunty that we do not pay rent and we are late all the time (obviously not true) and discussed my details with my partners aunty (who is not even a garantor or my lease, her home line was what i used when i stayed there), The landlord did not even mention that he had spoken to anyone.I found out when my partners aunty was blabbing my business to everyone in her family and that caused a family arrgument and is part of the reason my partner and I have now split our ways. Furiously I emailed that landlord, explaining that he knew full-well that my partner was due to give birth, I have never not paid him his rent, I explained that by discolsing my personel details to a third party, he was breaching the "Data Protection Act" of 1998, he replied apologising and accepting that he had unnessarly discolssed my personal details to a third party person. This incident has played a a big factor into my reaction to my partners family & the break down of our relationship, I have since been diagnosed with depression and I want to know what i do to my landlord legally because it seem unfair that I suffer and he gets away smiling. 2. My second issue is, when we moved into the house just over a year ago, the landlord presented us with a gas certificate for the two gas fires downstairs, this year when he had someone come round to do the inspection, the gas inspector shut them down and put a yellow tag round them, he said the gas fire heater in the dinning room, which we used had no anti-fire back to it (something like that) and he said it is dangerouse, the gas fire heater in the lounge is a fake coal gas heater that has real flames, he shut it down because it did not have ventilation (Or adiquate ventilation) he asked how often we used it and we told him that we have used it nearly everyday since she got pregnant and also once the baby was born we used that to heat room (with the door closed) he was shocked and said that we should not have been exposed to such danger. I have since found out that the landlord always used cowboy laboures in the past.The inspection was about two months ago and the land lord has not done anything to get them fixed, we have had to use electric heaters now which costs alot more, he has not even mentioned anything about the gas being unsafe. Should we be compensated for using the electric heaters now and how about all the time my partners, her two daughters and I have had bad chests could that not be from sleeping in the living room with the gas fire on and not enough ventilation? How about the effects it may have had on my new born (and yes we have seen the midwife and doctor about his chest and nose after he was born) because he used to have very bad wezzy chest and his nose was always clogged up. Where do i stand legally against my land lord on both issues, please help Thank you Carlos
