Pros
BUUK has a good record of taking on graduates and training them up through their graduate scheme, which is always nice to see. The working environment is good, fairly low stress, and most everyone who works at the company is very friendly and approachable with the benefit that the company really do seem to care about their employee's welfare. At time of leaving, there was a split on office and home working for the development teams which is a nice benefit.
Cons
The projects written by the development teams, both legacy and new, tend to be written in whatever way the lead developer fancies at the time. There's virtually no coding standards applied and projects are regularly written in different languages and expected to be able to communicate with each other. There is no one person guiding the development projects, which means they suffer from differing levels of technical know-how, especially when it comes to management. This manifests itself in developers never being given time to address technical debt or improve the underlying systems, always being expected to keep adding to monolithic applications built on very shakey foundations in order to keep users in the rest of the business happy. Until something breaks or a security hole is discovered, then it suddenly becomes a priority.
