You'll be 38 or so by the time you finish the course.
Now, there's no legal reason why you can't get a job. Just practical ones.
The reality is that many will not get a good paying job for 3 or more years after finishing. Can you live on less than £20K for that period of time? Do you have a family? How will their lives be affected?
You'll only have 20 years to "pay yourself back" and save enough for a livable pension. It may sound like a long time but given there's a cycle of 7-10 years in aviation, can you afford to lose your job in 10 years time and be out of work for a year?
These are all harsh economic decisions that you must weigh up before considering a full time integrated course. You can go modular and it'll probably take a year or so longer and you'll probably keep your house.
Many employers view sub 250 hour pilots at the age you'll be as a training risk. Whether they are right or wrong is immaterial, that is how they view you. If they hold that view, you won't be offered an interview. You won't know why, you'll just be told "you're not competitive".
One of the tasks of a pilot is to weigh risk/benefits.
