So many useful replies - sorry, was busy yesterday so haven't been back to thread until now.
I am minded to decline any offer for now and see if they come up with anything, but to put a few things into context;
The increase in net pay, so after tax and NI, is £1200pm. I took £450 off for the monthly cost of my season ticket, £150 off for monthly parking pass, and £100 pension contribution, leaving me with the £500 extra to put towards clearing a few debts. To the PP who pointed out that increasing my salary in order for DH to go part time made no financial sense, I meant he could go part time once my increase had cleared some debt and freed up some disposable income.
I am 47 and have a chronic foot problem after injuring it on the first day of a new London commute, 5 years ago (hurtling down 17 flights of steps at Bank)! I've just had an operation on it, fingers crossed it works.
Yes I have commuted before, it was a bit shorter overall than this one as I have moved house. Original commute was 7 min drive to station, 1 hr 10 mins on train, 5 mins tube ride, 8 min walk (1 hour 30). This commute is 14 min drive, 1 hr 20 min on train, 8 min tube ride, 2 min walk (1 hr 44). So in fact, only a few mins longer in total, and the office is a bit nearer the tube station. I'm quite far out so getting a seat in the morning is no problem - coming back in rush hour is murder though, might have to stand for 25 mins to Woking if the timings are tight and I can't get to the train early doors. Yes, I'd forgotten about the current problems at Eastleigh causing cancellations!
CEO struck me as a bit of a dick and the 2nd interview was really one sided, however - he is close to retirement and there is a succession plan. His deputy is younger, far more pleasant and tried to ask me more questions when he could get a word in.
The sporty competitive culture is very off-putting, I can't lie. But maybe it would spur me on to lose this bloody weight and get fitter, which would help my foot I suppose. They also encourage a policy of no eating or taking private calls at desks - not as in you can't eat or take a call or send a text, but so people take proper breaks and go and do personal stuff in a break out area (when I was shown the office at 1pm there were a few people milling around in a very flash, well equipped dining area), and eat lunch properly rather than being tied to their screens.
Potential to move - we have talked about relocating to a cheaper area with a shorter commute in to London anyway, so we haven't ruled it out. My DM has Alzheimer's and is in residential care nearby, but I could relocate her too possibly - a bit of upheaval but not completely out of the question. Her care fees might be cheaper too.
My current job is field based - so I might be home a couple of days a week, but the rest of the time I am on site with clients. They could be anywhere from 30 mins to a 4 hour drive away or in London; I am always on site for a minimum of 6 hours; and you are "switched on" in consultant mode all day, no mental respite and no breaks (often no food). I regularly stay away from home, sometimes all week if I'm flying north from Southampton.
The opportunity to get this experience - and exposure to senior management - is really important, as I'm not getting any younger and my current niche is no longer very marketable.
But...if I were to stay where I am I can slowly get more experience in the wider areas, albeit with a firm I despise and being away from home a fair bit, whilst being treated like an non-entity/expendable resource for £20k pa less...
