Is the 8k raise worth it?

Bit of background I’m 33, married, no kids and no plans for.

Current job 42k fully remote. Work 7-4, 30 min lunch break which is paid. 20 days holiday + bank holiday. Minimum everything. I breeze through my job but am somehow over performing. Second time at the company. First time 2 years, this time currently a year and a 3 months. No real opportunities to progress.

Job offer. 50k. 25 days holiday + bank holidays. Working hours 7-3. 2 days in office but it’s about an hour and a half drive each way. All mileage paid 45p a mile. Working for a company owned by people I know and have worked with both previously. Small company but security is the same as current.

My husband is just like you’ll hate the driving and no. The hours are reduced so I see it as only losing an hour a week extra to what I am currently doing now with extra money each month. The job will be more challenging but to be honest I’m at my current job for convenience not enjoyment.

Do you think the 2 days a week 3 hour round trip is worth it?

I’m also guaranteed an internal promotion at new role with business growth, likely to be 2 years. Next year would be a stretch so they’ve laid that out there it won’t be overnight. My current job I’ve been told id get one as soon as they can justify, which I see no movement in since my return.
