Whilst replacing the brake fluid on a standard service is not common practice - it is good practice as brake fluid is hygroscopic. Unless stored in a vacuum or under a dry gas it will absorb moisture from the atmosphere and then will have a greatly reduced boiling point - thus causing deterioration of the inner components of the brake system. Considering the complexity of modern braking systems (ABS, etc) an extra £30 is well worth the money - even if it only saves your life.
Remember brakes are like your best friends - you miss them most when they ain't there.
See link below for definition of hygroscopic
