Volunteer bureaux that refuse to take part in Volunteering England's rebranding programme will lose their accreditation.
The charity maintains that individual bureaux can decide whether or not to rebrand, but Chris Penberthy, director of capacity building and infrastructure development at the organisation, admitted: "The accreditation of individual bureaux will come up for renewal at different points over the next three years, and those that refuse to rebrand will lose it.
"This will not stop them doing the work they do, but it does mean they will lose access to resources."
The rebranding process, using a blue and yellow logo with a 'V' like a pair of wings, is two years into a programme that could take four. So far, 230 out of 300 bureaux have signed up.
Volunteering England has secured a total of £100,000 in grants from the ChangeUp volunteering hub for bureaux that need to replace their existing shop fronts or other external signage in order to rebrand.
Penberthy added: "This will be distributed on a first-come, first-served basis, and we will allocate 50 per cent of the cost up to £1,500."
