Hiring in Cardiff: what it costs employers in 2025/26

Cardiff is Wales's capital and dominant employment hub, with the Welsh Government, BBC Wales and a cluster of financial services businesses all headquartered or significantly present in the city. Public sector employment is proportionally larger in Cardiff than in most English cities of comparable size, and salaries tend to sit somewhat below UK national averages across most occupations. Employer NI (15% above £5,000) and pension (3%) apply at the same UK-wide rates.

Welsh Government and Cardiff Council roles follow national public sector pay frameworks, with administrative and professional roles typically ranging from £22,000 to £50,000. BBC Wales employs production, technical and administrative staff across salary bands from £24,000 to £60,000 for senior programme-makers and editors. At £30,000 — a typical Cardiff public sector mid-level salary — total employer cost is approximately £34,464 per year.

The Cardiff financial services cluster, including operations for major banks and insurance firms, tends to pay slightly below London and Edinburgh levels for comparable roles. Typical salaries range from £24,000 for operations and back-office staff to £55,000+ for experienced analysts and managers. At £35,000, total employer cost before overheads is approximately £40,363.

Cardiff salary benchmarks and employer cost worked examples

At £24,000 — common across retail, administrative and lower public sector roles — employer NI is £2,850 and pension approximately £531, giving total employer cost of approximately £27,381. At £28,000 (typical for Band D local authority and junior professional roles), total employer cost is approximately £32,101. Both reflect 2025/26 NI at 15% above the £5,000 threshold.

Cardiff's median private sector salary is somewhat below the UK average, meaning the April 2025 NI threshold change (from £9,100 to £5,000) has a proportionally larger impact here than in higher-wage cities. The additional NI on salaries of £22,000–£28,000 is approximately £790–£870 per employee versus 2024/25 — a meaningful rise for organisations with high concentrations of lower-paid roles.

Financial services and insurance operations staff at £35,000–£45,000 generate employer NI of £4,500–£6,000 per year, with pension of £863–£1,163. At £40,000, total employer cost is approximately £46,263. Senior analysts and managers at £50,000–£55,000 generate total employer costs of £58,072–£63,822 per year before overheads.

Employment Allowance and Cardiff SME employers

Cardiff's private sector includes growing tech, creative and professional services communities. Employment Allowance of up to £10,500 per year is available to eligible Cardiff employers and can significantly reduce NI liability for small businesses. Many Cardiff creative agencies, tech companies and independent professional practices have total NI bills below £10,500, meaning they can eliminate their NI entirely through the allowance.

A Cardiff digital agency with five staff at an average salary of £28,000 generates approximately £17,250 in annual employer NI. Employment Allowance of £10,500 reduces net NI payable to approximately £6,750 — a saving of nearly 61%. For businesses operating in Cardiff's lower-wage environment, the allowance provides proportionally greater relief than in London or Bristol.

The Employment Allowance increase from £5,000 to £10,500 in April 2025 is particularly impactful for Cardiff businesses. Previously, only a fraction of NI was offset for many firms; now the entire bill may be eliminated.

Frequently asked questions

How much does it cost to employ someone in the UK?

The true cost to employ someone in the UK is typically 15–20% above gross salary. At £30,000: employer NI £3,750 + pension £713 = approximately £34,463 per year. At £50,000: employer NI £6,750 + pension £1,313 = approximately £58,063 per year. Adding workplace overheads of £2,000–£5,000 can bring the total to 20–25% above the headline salary.

What is the employer NI rate for 2025/26?

For 2025/26, employer Class 1 National Insurance is charged at 15% on employee earnings above the secondary threshold of £5,000 per year (£96 per week, £416 per month). This rate increased from 13.8% in April 2025, when the threshold was simultaneously cut from £9,100 to £5,000. Both changes apply from 6 April 2025.

How much employer NI do I pay on a £35,000 salary?

At £35,000 salary, employer NI for 2025/26 is £4,500 per year — 15% on £30,000 of earnings above the £5,000 threshold. That is £375 per month. In 2024/25, the same salary produced £3,585 in employer NI. The April 2025 changes therefore add £915 per year on this salary alone.

What is Employment Allowance and who can claim it?

Employment Allowance lets eligible employers reduce their annual employer NI bill by up to £10,500 in 2025/26, increased from £5,000 in 2024/25. The previous £100,000 NI bill eligibility cap has been removed, so more businesses qualify. Companies where the only paid employee is also a director cannot claim. Apply through payroll software via the Employer Payment Summary indicator.

What is the total employer cost above salary?

Beyond salary, employer cost includes: employer NI (15% on earnings above £5,000), employer pension (minimum 3% of qualifying earnings between £6,240 and £50,270), and overheads such as equipment, software and workspace. For most UK salaries this adds 12–20% above headline pay. Use the inputs above to set your exact pension rate and overhead figure.

What changed for employers in April 2025?

Three changes took effect from 6 April 2025: the employer NI rate rose from 13.8% to 15%, the secondary threshold was cut from £9,100 to £5,000, and Employment Allowance increased from £5,000 to £10,500 with the eligibility cap removed. For a £30,000 salary, annual employer NI increased from approximately £2,884 to £3,750 — a rise of £866 per year.

How is employer NI different from employee NI?

Employer NI is a cost paid by the employer on top of gross salary — it does not reduce take-home pay. Employee NI is deducted from the employee's wages instead. For 2025/26, employees pay 8% on earnings between £12,570 and £50,270, then 2% above that. Employers pay 15% on all earnings above £5,000 with no upper cap. This calculator covers the employer side; for employee take-home pay see AfterTaxSalary.co.uk.

What are employer costs in the UK?

UK employer costs in 2025/26 are: gross salary, employer NI at 15% on earnings above £5,000, employer pension at minimum 3% of qualifying earnings (£6,240–£50,270), and any operational overheads such as equipment or software. For a £35,000 salary, statutory employer costs (NI + pension) add approximately £5,363/year before overheads.

How much do I cost my employer in the UK?

If you earn £35,000, you cost your employer roughly £40,363/year — your salary plus £4,500 employer NI and £863 minimum pension. At £50,000, the total is approximately £58,063. Your employer pays these on top of your salary; they are not deducted from your pay. Use this calculator to see the exact figure for your salary.

Is this a PAYE cost calculator for employers?

Yes. PAYE employer costs include employer NI — calculated at 15% above £5,000 for 2025/26 — plus the employer's auto-enrolment pension contribution. The full calculator models both alongside any overhead assumptions to give a total PAYE-basis employer spend per employee.

What is a cost to company (CTC) salary in the UK?

Cost to company (CTC) in the UK refers to the total annual cost of an employee to their employer — salary, employer NI, pension, and overheads combined. A £35,000 CTC salary typically means a gross salary of roughly £30,000–£32,000 once the employer's NI and pension obligations are included in the total. Use this calculator to work backwards from a CTC budget to a gross salary.
