HSA Dental Plan has just written to its 80,000 policyholders explaining that, because the two-year-old plan "has exceeded our expectations in both popularity and levels of claims", premiums are to go up and some benefits reduced from January 2009.
Despite the increased cost and reduction in cover, the policy is still a good alternative to paying unexpected dental costs out of your own pocket.
The annual limit for maintenance claims goes down from £150 to £100 per person and people can claim only 50% (down from 75%) of treatment costs, up to a limit of £1,000 instead of £2,000.
For people using an NHS dentist, who want a budget plan offering a lower level of benefits, HSA offers a core plan.
