Not every form of support needs to run through an organisation. Some of the most meaningful help a grieving household receives comes from attentive neighbours, particularly in the weeks after the initial support and sympathy visits have tapered off.
Check in a few weeks after the funeral, not just immediately after, when the practical support has usually already faded but the loss hasn't. Offer specific, concrete help rather than a vague "let me know if you need anything," a specific offer is far easier to accept. Include the household in ordinary invitations rather than treating them as fragile. Help with paperwork or logistics if the household is navigating anything administrative. And simply keep showing up consistently, grief support that stops after the first month often stops too soon.
None of these require formal training, and together they extend real support considerably further than any programme, including ours, can manage alone.
