As others have said move your bees as soon as possible.
The Dangerous Dogs Act 1991 states the following: Under the Act, it's illegal for a dog to be 'out of control' or to bite or attack someone. The legislation also makes it an offence if a person is worried or afraid (the term is 'reasonable apprehension') that a dog may bite them.
Since 2014 it has been amended to include dogs on private property. As the dogs have bitten and put you in fear of being bitten then the landowner is in contravention of the act.
Please report this to you local dog warden if you have one and to the police. If the police don't take it seriously (they generally do) remind them of the act.
If you need any legal advice Trevor Cooper of Dog Law can help. He deals with a large number of dog bite related cases and has helpful information on his website.

Even if you decide not proceed with anything for your own experience please remember that as the dogs now have have a bite history that they may well try and bite other visitors to the property. Is the owner aware that these dogs have bitten you?
Letting the dog warden know is important too. They may well have other reports of issues relating to this person and your information can provide further support to any case that might be brought against them.
