Posting this here from my Coram coordinator in case this is helpful
"Good question, I know a few organisations across the country have IV services.
Coram Voice have Slough, Hillingdon, City, Bromley, Harrow, Brent, Tower Hamlets, Hammersmith in London and South East.
And also services in Norfolk, Manchester, Coventry and Warwickshire- and probably some others that I am missing.
The adverts can be seen here: jobs.coram.org.uk/vacancies
I think some Counties/ Borough’s have their own services.
Action for Children have some other London Boroughs: www.actionforchildren.org.uk/how-we-can-help/our-local-services/find-our-services-near-you/london-independent-visitors-service/
And a quick chatgpt search says:
Barnardo’s – provides advocacy and Independent Visitor services in various areas (e.g., Plymouth, Cornwall, Wirral) through local advocacy teams.
Action for Children (London Independent Visitors Service) – matches volunteer mentors with children in care across London and beyond.
Reconstruct UK – offers Independent Visitors to looked-after children and care leavers in several regions (including Bristol, Reading, Gloucestershire, Milton Keynes, South Gloucestershire).
North Yorkshire Youth – runs a county-wide Independent Visitor scheme in North Yorkshire.
Specialist Organisations
ASIST – delivers Independent Visitor support with careful matching and structured support sessions.
TGP Cymru – operates the North Wales Independent Visiting Service for children in care in Wales.
NYAS (National Youth Advocacy Service) – provides Independent Visitor services on behalf of some local authorities (e.g., via Dorset Council).
It may just be best to go directly to the local Council site and looking at the “children and young people/ care” section and it should have more information."
