CTO Salary

CTO Salary

CTO salary data in the UK is notoriously difficult to benchmark. Figures vary enormously depending on whether you’re looking at a two-person seed-stage startup or a listed financial technology company — and the data sources tend to blend them indiscriminately. In this guide we break down CTO compensation by the variables that actually matter: company stage, sector, and location, using the most current 2026 market data available.

Average CTO Salary UK 2026

The average CTO salary in the UK sits at approximately £100,000–£102,000 per year according to the most-cited data sources. However, this headline figure masks an enormous range — a technical co-founder CTO at a pre-revenue startup and the CTO of a 500-person fintech scale-up both appear in the same dataset.

The spread between Indeed (£80K) and Glassdoor (£139K) reflects exactly this problem — both are technically correct but describe different segments of the market. The IT Jobs Watch and Payscale figures of £100,000–£102,000 represent the most balanced consensus for a working definition of the UK average across all company sizes and stages.

CTO Salary Per Month in the UK

These are gross monthly figures before income tax and National Insurance. A CTO on £100,000 takes home approximately £5,900–£6,100 per month net (2026/27 tax year, assuming standard personal allowance, no pension salary sacrifice). At £160,000, net monthly take-home is approximately £8,200–£8,600 depending on pension contributions and benefits structure.

CTO Salary by Company Stage

Company stage is the most significant variable in CTO compensation. The same role title describes very different jobs — and very different pay — at a bootstrapped startup versus a Series C fintech.

Seed Stage / Pre-Series A (0–£2M ARR)

Typical base salary: £55,000–£90,000

At seed stage, a CTO is typically either a technical co-founder (often accepting below-market salary in exchange for 1%–5%+ equity) or an early hire brought in to build the core product. Base salaries of £60,000–£85,000 are common, often supplemented by meaningful equity stakes that dwarf the base salary in expected value if the company succeeds.

Reddit’s r/cscareerquestionsuk places startup CTO salaries at £70,000–£100,000 as “relatively reasonable” — which aligns with actual market data for seed-stage hires in London and the UK’s major tech hubs.

Series A (£2M–£10M ARR)

Typical base salary: £95,000–£140,000

Series A funding brings the CTO role into proper market-rate territory. The company now has institutional backing, a growing engineering team, and a CTO who is responsible not just for building but for managing, scaling and making architectural decisions that will define the platform for years. Base salaries rise to £100,000–£130,000 with meaningful EMI options or share options that align with the company’s funding round valuation.

Series B (£10M–£30M ARR)

Typical base salary: £130,000–£180,000

At Series B, the CTO is a genuine C-suite executive managing an engineering organisation of 15–50+ people, owning the technology roadmap and presenting to the board. Base salaries at this stage typically reach £140,000–£170,000 in London and £120,000–£150,000 outside the capital. Annual bonuses of 15%–30% of base are common, plus refreshed equity grants.

Series C and Beyond / Scale-Up (£30M+ ARR)

Typical base salary: £160,000–£250,000+

The Fintech Times reports Series C+ fintech and SaaS CTOs in London earning £150,000–£300,000, with the most established roles reaching £275,000–£300,000 base. Total compensation — including annual bonus, long-term incentive plans and equity — at this level can reach £400,000–£600,000+ at high-growth companies approaching IPO or late-stage acquisition.

Listed / Enterprise CTO

Typical base salary: £200,000–£400,000+

At FTSE 250 and large-cap technology companies, CTO compensation is disclosed in annual reports. Base salaries of £250,000–£350,000 are typical at this level, with annual bonuses of 50%–100% of base and long-term incentive plan (LTIP) awards that can double total compensation in strong performance years. Total packages of £600,000–£1,000,000+ are not uncommon at the largest UK tech and financial services organisations.

CTO Salary by Sector

Sector drives significant variation in CTO pay — both in base salary and in the structure of total compensation. Financial services and SaaS consistently pay the most; public sector and NHS the least.

B2B fintech, SaaS and enterprise AI continue to lead on CTO compensation in the UK. At established London scaleups, the CTO role routinely commands £200,000–£300,000 base, making it one of the highest-paying non-commercial C-suite positions in the country.

CTO Salary by Location

London commands the most significant premium of any UK city for CTO roles, reflecting the concentration of high-growth tech, fintech and SaaS companies — as well as the higher cost of living expected by senior hires.

Remote and hybrid working has narrowed the London premium at seed and Series A stage — where many CTOs work remotely from lower-cost cities while being paid near-London rates. However, for Series B+ roles where the CTO is expected to be in the office regularly and present to investors, the London premium remains substantial — typically £20,000–£50,000 above equivalent roles in Manchester or Edinburgh.

Cambridge deserves a specific mention: the concentration of deep tech, AI and life sciences companies around the Cambridge cluster means CTO salaries there can approach or match London rates, particularly at well-funded spin-outs from the university.

CTO vs VP Engineering vs Head of Engineering: Salary Comparison

The CTO, VP of Engineering, and Head of Engineering titles are often conflated — but they describe distinct roles with different scopes and different market rates. Understanding the difference matters both for hiring decisions and for benchmarking your own compensation.

At early-stage companies, the CTO is often both the technical visionary and the engineering manager — doing the jobs of all three titles simultaneously. As companies scale, these functions typically split: the CTO moves toward external-facing strategy (investor relations, technical vision, architecture governance) while a VP or Head of Engineering manages the day-to-day delivery organisation. This split usually happens at around 20–40 engineers, or Series B stage.

In terms of pure base salary, VP Engineering and senior Principal Engineers at major tech companies can actually exceed a CTO’s base at a smaller company — the difference is in equity upside and strategic ownership, not necessarily cash compensation at every stage.

Fractional CTO Salary and Day Rates UK

The fractional CTO model — where an experienced CTO works part-time across one or more businesses — has grown significantly in the UK tech market. It is particularly common at seed and pre-Series A companies that need senior technical leadership but cannot yet justify or afford a full-time CTO hire.

A fractional CTO at £8,000–£12,000 per month on a two-days-per-week retainer represents significant value for a pre-Series A business that would otherwise be paying £120,000–£160,000 per year for the equivalent full-time hire — plus employer NI, pension contributions and equity. The trade-off is availability and context-switching: a fractional CTO working across three or four clients cannot provide the full-time focus and institutional knowledge of a dedicated hire.

What Factors Affect CTO Salary?

1. Company Funding Stage and ARR

As detailed above, company stage is the dominant variable. A £120,000 CTO salary at a seed company and a £200,000 CTO salary at a Series C company are both appropriate to their context — but the responsibilities, team size and equity expectations are completely different. Always benchmark against comparable stage, not just title.

2. Technical Specialisation

CTOs with deep expertise in high-demand domains command significant premiums over generalist tech leaders. The highest premiums in 2026 are in:

• AI / Machine Learning infrastructure — organisations building AI-native products are paying top-of-market for CTOs who can architect ML pipelines at scale
• Regulated technology — financial services, healthcare and defence require CTOs who understand compliance, audit and regulated system design; this commands a 15–25% premium
• High-scale distributed systems — CTOs with proven experience scaling platforms to millions of users are rare and highly compensated
• Security and cryptography — particularly at fintech, crypto and defence-adjacent companies

3. Equity and Total Compensation

Equity is often the most significant element of CTO compensation at growth-stage companies, and is frequently undervalued in base salary comparisons. A CTO accepting £20,000 below market rate in exchange for an additional 0.5% of a company valued at £50M is making a rational economic decision — the equity is worth £250,000 at current valuation, before any exit multiplier.

When evaluating or benchmarking CTO compensation, always calculate the total expected value including: base salary, annual bonus target, equity stake at current valuation, vesting schedule, and any anti-dilution protections.

4. Board and Investor Expectations

At Series B and beyond, CTOs increasingly present to board members and investors, attend investor due diligence processes, and act as a public face for technical credibility. CTOs who can credibly engage at this level — communicating technical architecture decisions in commercial terms — command a meaningfully higher premium than those who are outstanding engineers but less effective in board settings.

5. Previous CTO Experience

A CTO who has previously taken a company from Series A to exit commands a substantial premium over a first-time CTO — particularly at growth-stage companies where pattern recognition matters. “Repeat founder / repeat CTO” status can add £30,000–£60,000 to base salary expectations at equivalent company stages, in addition to stronger equity negotiating position.

Frequently Asked Questions

How much does a CTO make in the UK?

The average CTO salary in the UK in 2026 is approximately £100,000–£102,000 per year based on IT Jobs Watch (£100,000 median) and Payscale (£101,818). However, this figure blends early-stage startup CTOs with established enterprise technology leaders. Growth-stage and established CTOs typically earn £130,000–£250,000. In London fintech and SaaS scaleups, senior CTOs regularly earn £200,000–£300,000+ including bonus and equity.

What is the CTO salary in London?

CTO salaries in London range from around £100,000 at early-stage startups to £300,000+ at established fintech and SaaS companies. Morgan McKinley puts the London average at £120,000–£170,000 and Robert Half at £163,250–£274,000. At Series B+ fintech scaleups, The Fintech Times reports CTOs earning £150,000–£300,000, with the most established reaching £275,000–£300,000 base.

What is a CTO startup salary in the UK?

A CTO at a UK startup typically earns £55,000–£100,000 in base salary, depending on the funding stage and whether they are a co-founder or hired executive. At seed stage, some CTOs accept below-market salaries in exchange for equity (typically 0.5%–3% for a hired CTO, more for a co-founder). At Series A, base salaries typically rise to £100,000–£130,000 as institutional funding allows market-rate compensation.

Who earns more, a CTO or a CEO?

In most UK tech companies at growth and enterprise stage, the CEO earns more than the CTO. However, at early-stage technical startups — particularly those with a technical co-founder CTO — compensation can be equivalent. At listed UK technology and financial services companies, both roles typically earn £200,000–£400,000+ in base salary before bonus and LTIPs. The gap is generally wider at larger, more commercially-driven organisations.

Is being a CTO a stressful job?

The CTO role carries significant pressure — particularly around scaling infrastructure, managing engineering teams under delivery pressure, and translating technical decisions into commercial outcomes for non-technical stakeholders. Security incidents, architectural decisions with long-term consequences, and competing priorities from product, sales and the board all add to the pressure. That said, the role consistently ranks highly for job satisfaction — the combination of technical ownership, strategic influence and strong compensation makes it one of the most sought-after senior roles in the UK technology market.

What is the CTO salary per month in the UK?

Based on an average UK CTO salary of £101,000, a chief technology officer earns approximately £8,400 per month gross. Early-stage startup CTOs on £70,000–£85,000 earn approximately £5,800–£7,100 per month gross. Established CTOs at growth-stage companies earning £150,000–£200,000 take home £12,500–£16,700 per month gross before income tax and National Insurance.

What is the CTO salary in the NHS?

CTO roles in the NHS and broader public healthcare sector are typically structured around NHS Agenda for Change pay bands or equivalent senior manager pay frameworks. Most NHS CTO and Chief Digital Officer roles pay £85,000–£105,000, with very senior roles at NHS England or large trust group level reaching £110,000–£130,000. These roles rarely include equity or performance bonuses, but offer strong pension (NHS pension scheme), job security and work-life balance relative to the private sector equivalent.
