Yes, increments have been gone for years. So, you join as say a EO. The salary band is advertised as £20-£30k.
New joiners are expected to join at the minimum of the band. In exceptional cases, you can make a business case to start somewhere within the band but no higher than the £30k. This is usually based on extra qualifications, current salary etc.
Once you join, you stay on the same wage. It does not increase, you do not move through the band. The only pay changes are as a result of 'pay awards' which are signed off by Ministers. The Civil Service had 0 for 10 years and 0.5% in most depts last year. This doesn't apply if you start at the top of your salary band.
If you move to another dept within the Civil Service (e.g HMRC to DWP), you stay on your same wage if it's a level transfer and there is no option to negotiate.
If you get a promotion, you automatically go to the minimum of the next band with no option to negotiate.
Civil Service wages are stationary. They are slammed in the media and by politicians almost daily. The concept of ministerial accountability is disappearing. While the pension is good, (but no final salary pensions have been in place for over 20 years), the Civil Service is fast becoming unattractive and the view that Civil servants have an easy life is part of that problem.
