I think Drunky that you may need some kind of 3rd party cover if you are working in an area where the general public are admitted. But you may find that the National Trust are covered for this anyway and as you are working there with NT permission (I guess), that their insurance also covers your project....
With peace and consolation hath dismist, And calm of mind all passion spent...
