Do any British universities still offer degree registration from afar to those who study alone, without tuition? Forty years ago, London University was still offering degree registration to "external" students, who might be living anywhere in the world. To prepare themselves for the London exams, many studied at local institutions; but it was also acceptable for external students not to study at any institution but to study "privately". Some of these "private" students had private tutors, while others studied wholly on their own, without any tuition, and after being registered for the required period of time they presented themselves in a London or London-accredited examination room and sat the exam papers. Fees were paid both for registration and examination. For many decades, the availability of degree examinations to private students was considered one of the special features of London University.

I am not asking for recommendations, but are there any British universities nowadays that register and examine students who study wholly on their own?

Note that I am not asking about degrees by "distance learning" in which coursework is required and tuition bought from and given by the degree-awarding institution, or by an institution accredited by it, although it is possible that the kind of degree registration I am asking about might be considered a sub-category of distance learning.
The University of London still offers self study courses for international students. The list of courses includes both undergraduate and post graduate degrees in a range of subjects. While these courses are self study and do not include tuition, they are not cheap. For example, the fees for the Accounting and Finance (BSc) are:


  Academic year 2016-2017
  
  Application fee (non-refundable)  £ 84    
  
  Initial registration fee  £ 760
  
  Examination entry fee (per full course)   £ 224
  
  Examination entry fee (per half course)   £ 112   
  
  Continuing registration fee   £ 380
  
  Total for BSc degree  £ 4,292
  
  Other fees (as applicable)
  
  Additional registration fee for students taking law courses (per course)  £ 51
  
  Application fee for consideration of accreditation of prior learning (per full course)    £ 89


The fees are a little confusing since they are using course in two different ways. I think £224 fee is for a full year module.

At a total cost of £4,292, this is considerably cheaper than the £9,000 per year (£27,000 per for a degree) that most UK universities are charging. That said while program includes study materials, it does not include teaching.
