Guide for Head of Service
This guide helps Head of Service at Councils compare promotion timing scenarios from Chief Officer (SCP 44–50). The calculator shows gross earnings only; promotion still depends on vacancies, funding and employer policy.
Why promotion timing matters for Head of Service
Moving to a higher band or grade earlier means more years at the higher rate. Over five or ten years the cumulative difference can be substantial, even when the step from Chief Officer (SCP 44–50) to the next band looks modest year to year. This tool compares gross earnings under two promotion timings using illustrative pay from Local Government pay (NJC).
Typical progression for Head of Service
Service Manager → Head of Service → Director. Use the calculator below to see how pay changes over time.
What to compare in the calculator
Set your current band (Chief Officer (SCP 44–50)), years already in band, and how far ahead to project. Choose when the first promotion happens in each scenario and the target band after promotion. Optionally add a second promotion step for longer career routes.
Real world factors
Promotion depends on vacancies, performance, funding and policy. The calculator does not model competition for posts or time to complete training. Use it for financial comparison alongside career planning conversations with your line manager or union.

Frequently asked questions
What does this promotion timing calculator do for Head of Service?
It compares total gross earnings over a chosen period depending on when you are promoted, using typical pay for Chief Officer (SCP 44–50) and higher bands in Local Government pay (NJC). One scenario promotes sooner; the other later. Optional second promotion step included.
How should Head of Service staff use this at Councils?
Use it to see the financial shape of "promote now" vs "wait a few years" before you factor in non-pay reasons (workload, training, location). Promotion still depends on vacancies and Councils policy.
Does it use Chief Officer (SCP 44–50) pay from Local Government pay (NJC)?
Yes. We start from illustrative pay on Chief Officer (SCP 44–50) and move to the band you select after promotion. Spine points and increments follow the dataset; your actual pay point may differ.
Why can the earnings gap look large?
Higher bands pay more each year; over ten years small annual gaps compound. Real timelines include pay awards, part-time working and stepped progression. Treat the delta as a rough comparison.
Can I model two promotions for Head of Service?
Yes. Turn on the second promotion option and set the year and target band. Useful for roles with clear progression routes (for example Chief Officer (SCP 44–50) to the next band and beyond).
What does "years already in this band" mean?
It sets your starting salary on Chief Officer (SCP 44–50) before any promotion in the model. If you have been on the band for three years, you are likely higher on the spine than someone in year zero.
Where can Head of Service staff check official pay?
See your council HR, LGA or union for current rates and how promotion affects pay in NJC Green Book or local pay spine.
Are the results gross or net? Do you store my data?
Unless this page says otherwise, figures are gross (before tax, National Insurance and pension). We do not store inputs or results; everything runs in your browser.
Are these figures official for Head of Service?
No. All outputs are illustrative planning aids. Always check Councils, your union, regulator or official published terms for definitive amounts and rules.
