The rules do allow for occupational schemes (SSAS) to loan money back to the sponsoring employer, but not contract based pensions (such as a SIPP)

The loan must:

• Not exceed 50% of the net value of the scheme assets
• Be secured on a first charge basis on assets that have a value equal to the loan plus the interest charged
• Minimum interest rate is 1% over average base rate for the 6 main clearing banks, rounded up to the nearest 0.25%
• Term must be no longer than 5 years, but it is possible to roll over loans for one more period of up to 5 years
• Be repaid in equal installments of capital and interest
