St James's Place (SJP) has acquired Reigate-based specialist protection advice firm Future Proof.
The deal sees Future Proof, which has arranged over £800 million worth of cover for clients since it was established in 2011, become part of the SJP Group.
The firm provides specialist advice on income protection insurance, critical illness and live insurance in both personal and business markets.
SJP joint chief operating officer Iain Rayner said: 'In a short space of time, Future Proof has established itself as one of the leading protection advisory services in the UK.
'They have achieved this by focusing on the value of relationships and with an ethos that is very similar to our own – to provide the highest level of advice to clients so that their needs, and those of their families, are met long into the future.'
Future Proof chief executive David Mead added: 'To be able to now support SJP partners and clients with important and often complex conversations about protection marks the beginning of an exciting new chapter and is another step towards closing the protection gap that exists in the UK.'
