TBH it doesn't bode well that you're fairly clueless about market rates, the information is easily available!
Check itjobswatch.co.uk and do a bit of research on indeed.co.uk
I hire for all sorts of IT staff (testers, devs, analysts, and beyond - team leads, management, directors) and it really depends on your skillset and niche expertise. are you in financial services vs games development? there is a world of difference in the pay levels. likewise if you're member of staff that does project work vs. in operations. Or if you line manager others too, plus your role - you're going to get more.
So you need to do proper research and plug in those variables.
Since your circumstances are a bit of an unknown, though, I'd say it sounds very very low. Without wanting to give details, we hired a grad business analyst (central London office, limited travel requirements) and the starting band is 29k. our candidate is ISEB qualified as well as having a comp sci degree, but still - that's for someone with 6 months work placement experience in a small software house!
Our "actual" rate for BAs in Lond varies between high 20s and high 70s (after that you're really getting into managerial/director type territory rather than hands on stuff).
You need to gather up information on what a fair market rate is, basically.

It sounds like the FDM Group to me.
Is it?
Check them out on Glassdoor, or those types of companies - hopefully you knew what you were getting into when you signed up. There are benefits and risks, but you should have weighed them up before signing... again, research is key!
