SIPP for 69yo pensioner "umbrella" contractor!?

[Protagoras]

...still working on a contract, and paying taxes, contributions etc (as well as receiving my state pension)

Contributions to what? A pension scheme?

Shall I sign up to a SIPP, will it reduce my taxes; how and when will i access my SIPP fund? t.i.a!

Helicopter view, current rules,
- an Umbrella company may make employer contributions to a pension scheme, including a SIPP, subject to limits (£60k p.a. unless accessed a pension from a defined contribution scheme, when it becomes £10k p.a.)
- this contribution is paid from the gross amount received by the umbrella company
- there's no NI or tax paid on the pension contribution

Access a SIPP pension simply by instructing the SIPP provider to pay you a pension. Generally 25% may be taken tax-free and the balance is taxable as income in the normal manner. The SIPP provider almost certainly has a number of questions to be answered as part of the process.

It would be necessary to find an umbrella company that works with the chosen SIPP provider, or vice versa.

To avoid complexities such as recycling rules, it's simpler to defer taking any money from a SIPP until no longer contributing.
