TT Business Wholesale, which is what that is, has a good reputation. As do vivaciti themselves.
However that would be a proper migration as it would be a different connection ordered through Openreach, rather than an accounting change. I doubt if that could be speeded up, without an "expedited move" that OR charge for.
Also, on reflection, I'm not sure on the ISP change and an almost immediate house move after. If I was doing that I think I would be straight with the new ISP beforehand and pay up if there would be a charge.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
