What is the annual UK pension contribution allowance?

The annual pension allowance is £60,000 (or 100% of your relevant UK earnings, whichever is lower).

How much does a £10,000 gross SIPP contribution actually cost a 40% taxpayer?

You deposit £8,000 cash, the government adds £2,000 basic relief, and you claim back £2,000 on Self-Assessment, making the net cost just £6,000.

Calculation Methodology

Gross Contribution = Net Cash Contribution / 0.80. Basic Relief Added to SIPP = Gross Contribution * 20%. Higher/Additional Tax Rebate Claimed via Self-Assessment = Gross Contribution * (Tax Bracket% - 20%). Effective Out-of-Pocket Cost = Net Cash - Extra Rebate.
