Security on site

Go with what your insurance company says. Its not a case of what they prefer but, if stated as such, a mandatory requirement to avoid invalidating your policy.

Whatever the policy says, I would without fail always use the hitchlock as a bare minimum.

You will probably find that is a requirement for your insurance that a hitch lock and/or wheel lock are used when your caravan is unhitched.  So the answer is a definite yes.  I can envisage very few 'emergencies' when it is necessary to move a caravan whilst it is on a site, I have never come across one in my 50 yrs of caravanning - gosh is it that long!!.

I always fit the hitch lock & I carry a couple of wheel locks .. an Alko & a Bulldog Max ... trouble being it's often only when we're levelled up with the steadies down that I remember about them, and then the Law of Sod means that even the Bulldog won't fit!

On an earlier caravan I only used hitchlock as I found wheel clamps a faff and so adjusted insurance policy accordingly. On the last two caravans just the Alko wheel lock as I find it easy to use. 

With our caravan the alko wheel lock was declared for a discount as was the alarm and tracker. Fitting a hitch lock didn't secure a discount, so wasn't declared. When on site, I used everything, but only the declared items were required to be fitted / working.

Have you received a discount for having the devices?

On the last two caravans just the Alko wheel lock as I find it easy to use. 

Easy enough to use one of them when I remember 

With the first of the latest 3 vans I initially had alarm etc, hitch lock and wheel clamp after the first tour I amended the policy to remove the need for wheel clamp. 

On the second caravan I initially had hitchlock and Alko axle lock. After having a problem fitting the hitch knock on a very cold April afternoon and my hands that cold that I was near to tears I removed the hitch lock requirement.

 

I have declared that I use hitchlock and al-ko wheel lock so I guess a discount has been applied. I was just concerned whether their use when on site might contradict site safety  requirements.

I don't think you need to worry about not using your antitheft equipment.

Think of a MH, you don't leave your keys with the reception when on site, well not on any site I have been on so far!

I have a wheel clamp and steering wheel lock and use both  depending on the site's location and whether we would leave the van on site when out for a day. (only the steering lock is on the insurance)
