The standard procedure is to grant you leave for six months per visit. You have leave to remain for the time allowed to you on the stamp. However, it's up to you to make sure you're not making prolonged or frequent visits to the UK. Whilst it's possible that you could stay for 5 months, leave for a month, and then get another 6 month stamp, if you are in the UK for more than 6 months in a year, you will probably encounter serious resistance on any subsequent visit.
If you are sticking to your original plans and not spending more than 6 months in the UK in a 12-month period, you should not have any issues, but you should not expect to visit again until next year at earliest.
