Buy a ticket for the Boldon Tennis Lottery, or BoTL.
This was started in the early 1980s by the late Bill Ruffell when a new clubhouse was needed and has continued to be a regular source of income, raising tens of thousands of pounds over the years. Currently it raises around £1350 per year.

It's a simple premise. Commit to buying a weekly 50p ticket (number) in the draw, paid by a £2 direct debit every 4 weeks, and you could win £25 per week or £100 in the quarterly draw. For more details and to join the draw, download and complete this form and send a copy to Phil at boldon.ltc@outlook.com. Good luck!
