AIBU to entertain a job I don't have much experience in?

[antanddecland]

A Recuritment agency has contacted me regarding a job that's a couple of grand more than my current.

I've recently gone from £25 to £30k. This new job is £30-35.....

The company isn't advertising this role on their website - not sure how the agency have got wind of the job.

My current job I'm not getting much training in - and to be honest it's so boring and isolating.

This happened to me once -- not a wildly different department but a move from communications into fundraising. It was through an agency. I couldn't see why they didn't want someone with more fundraising experience but they seemed keen and it turned out they just wanted someone who they thought would fit with the team. I got it and it was...OK. I didn't love it but I got some good experience. I stayed for just over a year and went back into communications.
