It can. Although my understanding is that if one side purposefully generates high costs then they can get in a lot of trouble for doing so.
It's also worth noting that the UK is lowering the amount of fees you can get back. There's an upper limit on the percentage of fees you can get paid by the other side. This is essentially to introduce a higher cost to litigation through the courts and encourage sides to settle or go through an arbitration process.
