As far as I am aware, the BBC has embarked upon some very limited 4k trials with Sony (I think), these are simply "proof of concept" trials (mostly aimed at large outdoor screens for events such as Wimbledon), and in no way signal any move to 4k production.
In any case, even if programming is being shot and produced in 4k (aka UHD), broadcast bandwidth would always be an issue, and would make 4k a premium product that only a limited number of people could view. So I doubt very much if the BBC Trust would see this as in the best interests of the Licence Fee payer.
Plus, to get the most out of 4k, you really need a very large screen, and a large room in which to house it!, or sit very close to the screen!

“What kind of demand do you anticipate for 4K from license payers? Could the technology present difficulties in terms of funding?
I very much doubt we’ll find license-fee payers writing in saying ‘I demand 4k!’. Most consumers have not even heard of such a thing – and would in any case find such an ugly, technical label hard to understand. What audiences expect from the BBC is quality programming. ‘Quality’ can be hard to define, but it means a range of things from the storytelling and presentation to craft standards and picture quality. In the picture quality part of this, ensuring our programmes get through the distribution chain in good shape to the device the consumer is using is as important a focus as the technical detail of how many pixels there are. The financial challenge for a national public service broadcaster like the BBC is how to retain its commitment to universality (serving everyone, wherever they are, and however they consume our output), while remaining at the leading edge of quality.”
