That wasn't the intention at all. I'm not for a second 'judging' anyone. I'm certainly not suggesting that anyone were considering doing this to financially benefit.
I'm just suggesting that if when weighing it all up, £30 per month is a significant factor in somebody's decision-making, then...
I believe they have given assurances that this would not be affected.
However, personally I'd suggest that if that (£30 a month?) sum is a deal-breaker for anybody, then you're possibly not doing this for all the right reasons and should think really hard about whether this is for you.
