Groups that exist because one person shows up
Picture a Tuesday morning in a church hall somewhere in South Kesteven. A small group of people with sight loss arrive for their monthly social club — coffee, conversation, a familiar face. The person who unlocks the door, sets out the chairs, and knows everyone's name is not a council employee or a charity co-ordinator on a salary. They are a volunteer. If they stop coming, the club stops meeting. There is no deputy. There is no protocol. The South Lincolnshire Blind Society, headquartered in Grantham, is candid about this: its social clubs and coffee mornings across the county are described as 'independently volunteer-run', and the organisation itself acknowledges it 'wouldn't be able to provide even half' its services without the people who give their time.
The same structural dependency runs through several other specialist groups in and around Grantham. The local Fibromyalgia, Chronic Pain and Chronic Fatigue Support Group is peer-facilitated — run by people who live with these conditions themselves, not by professionals who have read about them. Alzheimer's Society Singing for the Brain sessions and Dementia Cafés rely on trained volunteer staffing to function at all. St Barnabas Hospice on Barrowby Road runs a Creative Wellbeing Group and memory-focused social events that 'heavily utilise volunteer befrienders and wellbeing assistants'. BHive Community Hub's out-of-hours, non-clinical support service is staffed entirely by trained volunteers.
None of these roles can be filled by someone who signed up for a corporate volunteering day or dropped in for a one-off task. Each depends on a specific person — often someone who has been showing up for years — holding knowledge, trust, and relationships that cannot be quickly transferred to whoever might be available next month.
The generation currently holding things together
The people currently keeping most of these groups running belong to the age cohorts that, nationally, still volunteer at the highest rates: adults aged 65–74 (23% formal monthly volunteering in 2024/25) and those aged 75 and over (20%). That statistic cuts two ways. It confirms that older adults are not withdrawing from community life wholesale — they remain the most active formal volunteers in England. It also means that specialist health groups are disproportionately dependent on the very cohort most likely to step back over the next decade through ill-health, bereavement, or the simple accumulation of years.
What this generation brings to these roles is not easily listed on a recruitment form. In peer-support settings — the Fibromyalgia and Chronic Pain group, the Dementia Café, the SLBS social club — the facilitator's credibility often comes from shared experience. A volunteer who has managed fibromyalgia for fifteen years brings something a trained but unaffected co-ordinator cannot: the authority of having navigated the same uncertainty, fatigue, and social isolation as the people across the table. That is not incidental to the role. In many cases it is the role.
Relational continuity matters just as concretely. Weekly befriending for someone living with dementia, or guiding a visually impaired person through an eye clinic appointment month after month, works precisely because the same face keeps appearing. Recognition, trust, and a shorthand built over time are not optional extras — they are what makes the support functional. Replacing that person with a succession of new faces does not preserve the service in a different form; it ends what the service actually was.
A national decline that lands hardest close to retirement
The pipeline feeding those roles is measurably narrowing. England's Community Life Survey (2024/25) records monthly formal volunteering at 17% of adults — down from 27% in 2013/14. The sharpest damage falls on people aged 50–64, the cohort that would ordinarily be moving into the sustained, relationship-heavy roles that specialist groups depend on: monthly participation in that group has dropped from 23% before the pandemic to 16%, with almost no recovery as of 2025. This is not a temporary dip. The Centre for Ageing Better calculates that 1.16 million fewer people aged 50 and over now volunteer formally each month compared with 2019 — a loss of more than 110 million hours a year, valued at up to £4 billion. Health problems and old age are the most commonly cited reasons for stopping; cost-of-living pressure adds to this.
In other words, the group most likely to age out of active roles over the next decade is not being replenished by the cohort directly behind it. For Grantham's specialist groups, that gap is not an abstraction — it is the succession problem, already under way.
Why a corporate volunteer day cannot fill the gap
The arrival of younger volunteers is real — since the pandemic, the average age of a new British Heart Foundation volunteer has fallen from 50 to 30. But that shift brings a change in the model of giving time, not just the face doing it. The newer cohort tends to prefer flexible, digital, task-specific commitments: a single afternoon helping with a fundraising event, a defined project with a clear end date, a short burst of online support. Micro-volunteering platforms — including CVS Lincolnshire's brokerage service — are built deliberately around this preference, lowering the barrier to entry to widen the recruitment pool.
What they cannot generate is sustained, embedded, relational presence. The gap is structural rather than motivational: the role architecture of a dementia café, a peer chronic pain group, or a blindness befriending service was built around someone who turns up every week, recognises which members are withdrawing, holds the referral relationships, and carries years of accumulated knowledge about individual circumstances. Very little of this is ever written down.
That is the tacit knowledge problem in its most practical form. Who knows that a particular member has not answered calls for a fortnight? What happens to that awareness when the co-ordinator retires? Nationally, 79% of charities already struggle to fill trustee and leadership vacancies — a systemic signal that the leadership layer in small volunteer-run groups is thin across the board. For groups with no paid staff at all, one departure can remove the group's entire operational memory in a single afternoon.
What local infrastructure can offer — and where it stops
There is local infrastructure working on this. CVS Lincolnshire — the county's only accredited Volunteer Centre, holding the national VCQA quality mark — operates a brokerage platform that matches volunteers to organisations, promotes micro-volunteering for those with limited availability, and runs targeted outreach aimed at 16–24-year-olds. Age UK Lincoln and South Lincolnshire is also recruiting younger volunteers specifically as digital champions. These are genuine and necessary services.
The honest limit is structural. Brokerage is designed to solve a matching problem: connecting available people to open roles. That is valuable, but it is a different problem from the one specialist health groups face. A platform cannot generate the week-on-week relational commitment that a dementia café or peer chronic pain group depends upon, and it has no mechanism for transferring the tacit knowledge a long-serving co-ordinator holds. The succession gap in specialist groups sits downstream of what any brokerage service — however well run — is built to fix.
The tipping point no one in Grantham is tracking yet
Elsewhere, the scenario has already played out. Age UK Kent Rivers has permanently closed — not because the need disappeared, but because older committee members burned out and no one was ready to take over. Community transport schemes that provided hospital appointment lifts in other areas have folded when their volunteer cohorts aged out at the same time. These are not distant cautionary tales; they are direct analogues to the peer-support and specialist services operating in Grantham today.
The South Lincolnshire Blind Society is the clearest local example of a group sitting in this structural position. It has openly acknowledged an ongoing volunteer shortage that limits what it can provide, and its satellite social clubs across South Lincolnshire are independently volunteer-run — meaning each one is, in effect, one resignation away from quietly ceasing to exist. No equivalent public signal has yet come from Grantham's dementia cafés, chronic pain group, or hospice befriending services. But the absence of a public signal is not evidence that succession is in hand; it may simply mean no one has yet been asked.
The practical question — for anyone who uses, refers to, or cares about one of these groups — is straightforward: does it have a succession plan, and does anyone outside the group actually know what is in it?
