Spinal Column Points (SCPs) are a set of salary levels. Together they make up the national pay spine, which is what the NJC negotiates on. Due to the introduction of the national pay spine in 2019, SCP start at SCP 1 and the highest is SCP 41. The NJC rates for SCP l at 2020 are at £9.25 an hour, giving a full-time annual salary of £17,842.
These salary levels are used by employers to design their local pay grades or pay scales and there are many variations, depending on which local authority you are contracted to work in.
