There are a few outpoints here. £20/day and "more expensive than the CofS" seems like contrary data. £20 is very inexpensive for a day of study. Fringe psychology courses run at around £100 a day. e.g.

Guessing at 10 students for a day, that would give £200 to cover premisses, food and whatever other logistical costs. The suggestion that the money would be going toward a building just isn't realistic. If highly trained people were flying over from outside the UK to assist then the money most probably was all spent on their expenses and fees.
What you appear to have seen in the UK is much the same as has happened over the last 20 years. Some people get together start up a group and it falls apart for various reasons.
The AAC started in EG in 1984 and was initially doing well. Most of the money was going to the lady who owned the house in which it was operating. The CofS destroyed that when she reportedly sold some copies of LRH tapes to a plant and was sued.
Steve Bisbey set up shortly after but soon switched over to doing Metapsychology. Robin Scott set up an ACC in Candecraig. The CofS got him into jail on a setup. The group fell apart and started using Bill Robertson "tech". Then Dianology took over and Robin started to supplement his income growing marijuana for which he spent a while in jail.
Mick and Eva Manias held together a small group for a while with meetings. The main problem they seemed to have was that the people involved all wanted to sit around talking about their particular preferred alterations to Scientology. Very few seemed to want to actually get on with auditing or contribute realistically to setting up training.
If someone is going to set up a workable UK training center then I would say they need to institute realistic pricing and they are not taking on an easy job. The UK has never been an easy place for Scientology to operate in. Saint Hill relied mostly on overseas students for its income. London org was never viable.
A group isn't going to be established without members taking responsiblity for it. Expecting Terril to hold it all together while others complain just won't work.
