I'd be very up front with asking them why it has just been surveyed, and use your own judge of character to see if you think they are being honest with you.
Tell them you want to have your own survey anyway, and see if they start telling you that you don't need to etc. That would not only be a red flag to me, but I'd also be annoyed that they are taking me for someone who is gullible. The first bit of advice everyone is told when looking for their first boat is "get your own independent survey".
That said, someone above has suggested this might be a 'stock boat' and owned by them, as Venetian Marina and their sister company Whilton Marina are both known to buy boats for cash to then sell on. If this is the case with this boat, it makes sense for them to have it surveyed when they buy it so they know what they are marketing.
When you ask them why it's just had a survey, if this is the answer then personally I would still recommend a 'newbie' get their own independent survey, but if the previous surveyor was willing to transfer the survey into your name from a liability point of view, then you've got a question to ask yourself and the opportunity to save best part of £1k.
I'm not sure if it's still the case with all insurance companies, but I thought most required you to have an up to date survey in YOUR name to give you insurance, albeit I don't think this boat will have reached the age yet where it needs a regular survey for insurance purposes?
In terms of the boat, it's not to my personal taste with the square cruiser stern, but something I think it's important for you to realise is that the only hot water heating is from the engine into a calorifier.
I'm not sure if you'll be Continuous Cruising, living aboard full time, in a marina etc... but you will only have hot water once you've run your engine for about an hour, and then that water will only stay hot and useable for a certain amount of time.
So when you wake up in the morning, you'll have no hot water. You could install a secondary water heating system, but don't underestimate how much that will cost. Imagine your engine starts playing up at some point, you'll have no hot water at all. In summer that'll be annoying, but in winter it could be very demoralising.
Something I always recommend to peoptis to have 2 different ways or generating cabin heating, electricity and hot water. So if one fails you've got a fall back. Boating can do very quickly become no fun when systems start going wrong, they cost a fortune to repair and you can't charge your phone, run the fridge or keep warm.
Lastly, do a bit of research into Liverpool Boats, now known as Collingwood. They are mass produced and people have varying opinions on them. Just because it's a 2008 built boat, I don't think that's a guarantee it hasn't had remedial steelwork done, or need it doing.
