Civil Service job adverts are labelled with grades like AO, HEO or Grade 7, and it isn't always obvious what those actually mean, how they relate to each other, or what pay to expect. This gets more confusing if you're comparing roles across Great Britain and Northern Ireland, since NICS uses some genuinely different grade names for the same rungs on the ladder. This guide sets out both structures clearly, along with official current pay figures where they exist and where they can be reliably checked.
The Standard UK Civil Service Grade Ladder
Most UK Civil Service departments use a shared structure. Job titles and specific responsibilities vary by department, but the grade itself is broadly comparable wherever you see it advertised.
| Grade | Typical Level |
|---|---|
| AA / AO | Administrative Assistant / Officer — entry-level operational and support work |
| EO | Executive Officer — first supervisory or specialist casework role |
| HEO | Higher Executive Officer — team or workstream ownership |
| SEO | Senior Executive Officer — senior delivery or policy leadership |
| Grade 7 | Senior specialist or team leader, managing HEO/SEO staff |
| Grade 6 | Deputy-director-adjacent, leading multiple teams or major programmes |
| SCS | Senior Civil Service — deputy director and above |
Roughly speaking: AA and AO staff handle day-to-day operational and support work within a team structure. EO adds a first layer of independent decision-making and sometimes casework ownership. HEO and SEO are the core middle-management grades, typically running a workstream, project or policy area and often managing junior staff. Grade 7 and Grade 6 are experienced specialists and senior managers, usually leading a team of HEO/SEO staff and taking accountability for outcomes in their area. The Senior Civil Service leads departments and sets strategic direction.
Official Current Pay Bands
Civil Service pay is not set on one single national scale. Cabinet Office publishes pay remit guidance capping the average uplift each department can apply, and each department then sets its own pay award and bands within that. This means the same grade can pay noticeably different amounts at different departments, and London or high-cost-area roles typically carry a location allowance on top of the national figure.
The table below shows the national minimum salaries published by Defra as a representative example of the standard structure. Use this as an illustration of the shape of the pay ladder, not as a guarantee of what any specific role pays; always check the individual job advert for the exact figure.
| Grade | National Minimum (Defra, illustrative) |
|---|---|
| AA | £25,445 |
| AO | £26,025 |
| EO | £29,715 |
| HEO | £34,765 |
| SEO | £42,665 |
| Grade 7 | £56,375 |
| Grade 6 | £67,730 |
NICS Uses Different Grade Names
The Northern Ireland Civil Service developed its own grading structure separately from the rest of the UK Civil Service, and the naming diverges in the middle of the ladder. Grade 7, Grade 6 and the Senior Civil Service use the same names in both systems. Below that, NICS uses a different set entirely.
| NICS Grade | Broadly Analogous To |
|---|---|
| AA (Administrative Assistant) | AA |
| AO (Administrative Officer) | AO |
| EOII (Executive Officer II) | EO |
| EOI (Executive Officer I) | EO / HEO |
| SO (Staff Officer) | HEO |
| DP (Deputy Principal) | SEO |
| Grade 7 | Grade 7 |
| Grade 6 | Grade 6 |
If you're used to GB Civil Service terminology and see a NICS role advertised as Staff Officer or Deputy Principal, this table is the quickest way to place it on the ladder you already know. The reverse is just as useful if you're applying to NICS for the first time coming from a GB role.
NICS pay scales are set separately from the rest of the UK Civil Service and are reviewed through their own annual pay award. Rather than repeat a figure here that may be out of date by the time you read this, check the current pay scale directly via NICS Recruitment or your NIPSA members' guide, which will always reflect the latest agreed scale.
What Grade Actually Means for Your Application
The competency or behaviour indicators you're assessed against scale directly with grade. A HEO example describing how you supported a decision looks different from a Grade 7 example describing how you owned one, even if the underlying competency is the same. Broadly:
- AA/AO and EO: examples can focus on your own individual actions within a supported team structure.
- HEO and SEO: assessors expect to see you managing ambiguity, owning a defined area, and sometimes directing others.
- Grade 7 and above: examples need to show strategic judgement, influence beyond your immediate team, and accountability for outcomes, not just tasks.
This is exactly why grade-specific preparation matters more than generic interview advice. Our SEO vs Grade 7 guide goes deeper on the jump many candidates find hardest.
Frequently Asked Questions
What is the order of Civil Service grades?
From most junior to most senior: AA, AO, EO, HEO, SEO, Grade 7, Grade 6, then the Senior Civil Service. Most UK departments use this ladder, though NICS uses different names between AO and Grade 7.
Why does NICS use different grade names?
NICS developed its own grading structure historically. Between AO and Grade 7, it uses Executive Officer II, Executive Officer I, Staff Officer and Deputy Principal, where the rest of the UK Civil Service uses EO, HEO and SEO. Grade 7, Grade 6 and the Senior Civil Service use the same names in both.
How much does each Civil Service grade pay?
It varies by department and location, since each department sets its own pay award within a national framework. Always check the specific job advert for the exact figure rather than relying on a single published number.
How long does it take to move up a Civil Service grade?
There's no fixed timeline. It depends on the department, vacancy availability at the next grade, and your own readiness and performance. Some competitive promotion points, such as SEO to Grade 7, tend to take longer than others.
