How much does your dental plan cost?

Just had notice of a price increase for my private dental plan.

Currently about £15 p/m increasing to £25.99 on 1st April. Jokers.

For this I get

2 very hasty 6 monthly checkups

1 yearly x-ray

Fastest scale and dab of polish you ever seen

The monthly checkups are also pushed back a month each time (sneaky).

To me, £312 p/a for this seems a lot?
