A Repair Café, run by volunteers and organised by Wycombe Environment, is operating in High Wycombe (All Saints Parish Church in the centre of High Wycombe). Bring your broken household items (mechanical, textile or small electrical) and you may be able to get them repaired. There will be no charge (except if a new part is required), although any donations will be very welcome.

Every 2nd Saturday of the month, in High Wycombe.
(note also that there are other Repair Cafes nearby, eg in Marlow and Hazlemere)
