Pension Tax Relief - Scotland

Hi, looking for some advice please, I am looking to pay more money into pension and hopefully regain personal allowance (£12750) and tax relief on pension contributions to reduce gross income to £100k. Currently pay into a pension scheme via salary sacrifice through employer but a one off bonus payment will not be open to this option. I will need to manage the process myself. Will remain under the £60k threshold for Pension contributions. For discussion purposes say gross salary is £125k am I correct in saying if I pay £25k gross into my private pension then I need to make the net payment of £15k (assuming 40% tax relief) to pension fund. Pension fund then claims the tax relief from HMRC? This takes salary to £100k and re instates my £12750 allowance? Thanks in advance NB
