Help Should I Draw Pension But carry on working?

fjh

I am in a final salary scheme that has recently changed, it was a 40/60 scheme but due to costs Normal Retirement now at 65
I would like to retire if possible at 63
I still have a mortgage outstanding and one option is to draw my pension at 58 when I will have 40 yrs in scheme + enhancement of 2.9 yrs= 42.9 yrs in scheme , as well as the pension as i would be coming out of the scheme the 15% my employer pays into my pension would then be paid to me in addition to salary
I have done all the 'Math' and Drawing max pension only taking cash the AVC part (worth £20k) i would have to live past 85 for a pension taken at 58 to 'overtake' waiting till i retire say at 63
My intention would be overpay my mortgage and put max £250 pm into BAYE shares which as I am a 40% tax payer would help
I have tried to gain advice but as I am not 'buying' anything this has been difficult ( again suggestions would be welcomed), ideally I would be open to suggestions as to how I could 'save' tax on the combined Salary & Pension monthly
Any 'pitfalls/drawback' again would be appreciated
Thanks in anticipation of any help -

I don't think you have done your math correctly, and fear you have forgotten the indexing of the pension each year.

Is your pension indexed by RPI, CPI or a set %?

Sorry I was trying to keep detail 'contained'
In the spreadsheets I have done I have added inflation to pension figures based on 2.5% each year from age 58 to age 85
