Teddington Electric Piano

Bit of a long shot perhaps. I am travelling from Ireland to a relative's birthday party in Teddington. They have asked me to play a little (some solo, some sing song). Naturally I can't bring my piano. So, does anyone know where an 88 key (or slightly less) Electric piano could be borrowed? Say from a local school, church, community centre.

Or if there is a hire place for such I can ask the birthday boy if there's a budget for this. The piano could be something like a Casio Privia, Yamaha P120 type for example. Would need in built speakers.

Thank you.
