Would you leave a job you love for double the salary?

Well it's up to you if you want to make this about patriarchy. Not everyone is into a career and it doesn't actually sound like the OP is.

I earn loads and whilst it's comfortable and I don't want to go back to earning 50k there really is little point in making more than 100k as you know. Unless it's significantly more. It's great for the pension pot, but we also live now and looking back I regret that I was miserable and stressed all through my 30s. It will only have been worth it if I actually get to 60ish to draw my private pension. Maybe some cancer will kill me at 50, who knows?

Now I'm mid 40s stuck in a golden cage.

Can you check out the company on glass doors etc these days

Yes👍 I would. Clearly you can manage with the demands in the current job and can apply the same principles in the higher paid job.

Secondly, you've made good relationships in the current job so you obviously know how to work well with people.

The tax situation is crap! As per pp, pension it.

What is the overall financial package? How does it compare to your current?

More money will mean more responsibility but
You could always go back to a smaller company after a few years because it you have more scope and experience with a broader range of skills, you could be highly employable

If you want to buy somewhere then the difference in what you can borrow on your mortgage is worth it alone.

Sounds like a fantastic opportunity, crack on. The next step after this is £150 or £180 and you are so much closer if you take this role.

I've just done similar, though 40k to 75k. For me it's a massive difference to take home pay and will mean I can easily pay off my mortgage ~15 years early.
I did however requested the second interview to be in person, and to ideally meet some members of the teams I'd be working with. I left a department where we were like an extended family rather than work colleagues, so I wanted to be sure I wasn't walking into a toxic environment. Interviewers found this interesting, but happily arranged it.

Thankfully I haven't, new place is fantastic, a great new challenge for me but definitely within my skills, as nd everyone has been genuinely welcoming and friendly.
My old team were super happy for me and we still go for lunch regularly for a catch up. I'm not sure i would have left if it wasn't such a massive difference in take home pay for me however.

I'd take the money without a second glance, no matter how much i enjoy my job.

Workplaces change and there is no loyalty anywhere anymore. A job you enjoy can quickly become one you hate, and then you are just being underpaid.

I would take the money and use to do the things I love doing outside of work with my actual friends and family.

No I wouldn’t, but then we don’t really have money worries. I probably would have done when we were less comfortable. More money would definitely be nice, especially with kids off to university, but not to the point where I’d leave a job I love.

No, never. I have to feel a connection to what I do and really believe in it and love it. Atmosphere and relationships count a great deal to me, feeling happy where I am would count a lot.

You may be different though- only you will truly know which option will bring you greater overall happiness.

Good luck!

No because my thinking is (unless you felt massively underpaid) a double pay rise means an incredible work rise .. can you cope with that?

Difficult decision OP.
Only you can decide.
Money definitely isn't everything but it's important to have enough. You are currently earning 70k which is very good. It's also important to remember that change is good too and ime it isn't always good to stay in a workplace for a very long time.
I previously had a job in a prestigious organisation that was absolutely toxic. I truly hated giving to work every day and left as soon as I found another job.
I have also worked in places where I have truly loved going to work.
You need to weigh everything up. It is all a gamble

I hear you OP. I love my job but I desperately need to earn more. The money would be very tempting, but what are the strings??

Absolutely but I am getting towards the end of my career.

No. Never.

What you have money can't buy.

It is disheartening to see women so actively discouraging one of their own from taking advantage of a fabulous career opportunity. It is the same women who refuse to believe other women can be super high earners.
OP, every new career move is a risk. It is up to you how you navigate it. Nothing is insurmountable if you put your mind to it. The job is not brand new. You will find someone has done exactly the same job before or something similar. You will find people and situations you can learn and grow from. Grab it with both hands. Opportunities like this don't come round often. Put 31k in your pension if you want to avoid the tax cliff edge, you will still be nearly 30k better off. Building your pension now will give you much more choices in 10 years.
First stop 130k, next stop 200k. Go and make your mark and bank the money.

Could you do 4 days instead of 5 at the new job to reduce the salary to £104k?
Then you could stick £5k into pension to stay below £100k.
That's what I would do if it's possible

Goes without saying that anything above 100k needs to go into pension. It will make a big difference in a few decades, not now.

So this is the same kind of job, not a promotion type job? If it's the same kind of job it sounds too good to be true or it means you are currently being underpaid by a lot. Which one is it? Even in a job I love I couldn't handle being underpaid massively. It would erode my morale. I definitely think they'd want their money's worth at 130k. It would be different from your current culture.

If it's a promotion type job, well do you ever want to go for this kind of promotion or not?

What exactly do you love about your current job, especially if it's the same kind of job you have been offered?

Like others said what is the actual take home pay difference? Will you have to work extra hours unpaid for that extra pay? Are there any extra costs, commuting / lunches or travel time with new role?

If the extra money was going to make a significant difference to my life or my financial security, yes.

If the pay rise would place me into a tax trap and most of the extra was going to be confiscated by Rachel Reeves, no.

I don’t think so, I really do love my job.

From 70k to 130k- you may find not actually much difference in take home pay- as you lose the basic tax allowance....
I would look into this before even thinking of it
I am not sure I would do it. From 30k to 70k deffo worth it, from 70k to 130k- probably not much more than 1k take home pay a month.... Not worth it ....

The happinesss/money graph levels off quite close to the start of that range. Would your current job give you an extra 10K?

No I wouldn't. Being happy in a job is more important to me than money. Assuming you earn enough in your current role then I would stick with it, as there is always the possibility the new job won't be as described and you will wish you had stayed put.
