Laya website has a useful easy comparison tool (click on Join Laya, then on Compare your scheme). If you input your VHI scheme, it comes up with Inspire and Inspire Plus, both cheaper but very good schemes and with only minor differences to yours. You have the option to show only the policy differences.
With a few complicated exceptions I would suggest that most people don't need to pay for advice, just to spend some time doing their research and comparing policies, working out what their health and financial priorities are. I do this every year for both of us - currently on Inspire Plus and Simply Connect Plus - and I've never found a VHI plan comparable to the latter.
VHI is a not-for-profit organisation by the way, and the other health insurers need to stay competitive. I don't like the price rises either but definitely shop around.
