Yes, you can invest in a SIPP or SASS. For more information about investing via a SIPP or a SSAS please visit the SIPP Club. Please note, this is a specialist asset class, with few providers currently accepting peer-to-peer investments.
On 6 April 2016 the new Innovative Finance ISA (IFISA) was launched. The IFISA enables investors to invest up to £20,000 in the April 2017/18 tax year in a peer-to-peer platform, whilst receiving tax-free interest and capital gains.
Lendy is looking to offer an IFISA via our Lendy Wealth accounts for the 2019/20 tax year.
