UK Standard visitor visa for multiple business trips [closed]

I have a question regarding visiting the UK on multiple occasions for business. I am living in another European country with a permanent residence permit there. The visits to the UK would last 2-3 weeks, then 1-2 weeks home, 2-3 weeks UK and so forth, given a standard visitor visa is present. Would the IO be suspicious about the frequent visits? It is not work, but business in a consulting/training area which requires frequent presence in the UK at our business partners location. I do not directly do business with clients of our partner. I am paid by my employer in the home country and I do not intend to migrate to the UK. Would these type of visits require another visa and which one would you recommend? I do not want to cause distress of removal on the UK border and cause a permanent rejection for future visits to the UK. So it is important to find a legal way for frequent visits in a time period of approx, one year (I would have to apply for a new visa after the current one has expired).
