As an existing customer on their (4 Mbps SDSL) residential service, I understand we are getting moved over to this new service this month, so if there's anything useful to report I'll post back.
Generally their 4Mbps service achieved an aggregate of up & down speeds of between 7 and 10 Mbps split 6:4 (which could be either way!). I think that was its max. using, I believe, a Nanostation 5 receiver on the TV aerial pole, as the highest point on my roof, some 6km from the transmitter. The installation and CS were exemplary, and the service too through the winter. The downtime was normally less than an aggregate hour or so a week, usually overnight, apart from the inevitable disruption during works on the new upgrade. I think I'm lucky being on a hill, and mostly not obstructed by trees or higher buildings, but I surmise that neither are problems over much of the Dengie/Essex coast, which makes it a suitable area.
A couple of things which might need clarification are an installation cost for the aerial/connectors (mine has a power supply over ethernet cable) and contention (less likely I assume on the higher cost business packages). Download speeds tended to be a bit higher in the later evenings. Also if t&c's remain the same it's a 12m min. term, with auto- renewal thereafter for 12m unless 30 days notice of termination given before the anniversary, though of course they might not implement this.
