Nairobi occupies a unique position in Africa: a dynamic, fast-growing city of approximately 5 million people that serves as the headquarters for regional operations of hundreds of multinationals, the East African Community, UNEP, UN-Habitat, and an expanding ecosystem of technology, development finance, and social enterprise organisations. For international professionals — particularly those in development, finance, technology, healthcare, and NGO sectors — Nairobi is the most common East African assignment and one of Africa's most liveable capitals.
Beyond Nairobi, Kenya offers some of the world's most spectacular natural environments: the Maasai Mara, the Rift Valley, Mount Kenya, the Lamu Archipelago, and a coast that runs from Mombasa to Diani Beach. For those who have worked in or fallen in love with Kenya and are considering a longer-term commitment, this guide covers the practical financial and administrative considerations.
Why international professionals choose Nairobi
The regional hub role: Nairobi hosts the African headquarters of major banks, tech companies (Google, Microsoft, IBM), development finance institutions, and international NGOs. East Africa's growth trajectory — and Kenya's relative stability compared to some neighbours — makes it the default base for regional operations.
Infrastructure and connectivity: Nairobi's Jomo Kenyatta International Airport connects directly to London, Amsterdam, Paris, Dubai, Doha, and numerous African destinations. The standard of international hotels, conference facilities, and high-end residential properties is comparable to many Western cities.
The expat lifestyle: the Westlands, Gigiri, Karen, and Lavington areas of Nairobi have established expat communities with international schools, good supermarkets, private hospitals, sports clubs, and social networks. Quality of life within these areas can be very high.
Kipaji programme and tech ecosystem: Kenya has developed a significant technology and startup ecosystem (M-Pesa, the world's pioneering mobile money platform, is Kenyan). Nairobi's iHub and various accelerators attract regional talent.
Visa and work permit routes for UK nationals
Entry visa
UK nationals require a visa to enter Kenya. Since Kenya's migration to the eTA (Electronic Travel Authorisation) system:
- A tourist ETA can be obtained online (approximately $30) and permits a 90-day stay per visit.
- Business visits can be managed on tourist ETAs initially but formal work authorisation is required for employment or commercial activity.
Class G Work Permit
The primary work permit for employed expatriates. Issued to employees of Kenyan companies (or registered branches of foreign companies). Applications are made through the Department of Immigration. Employers typically handle the application, but the employee must be named. Work permits are initially valid for two years and renewable.
Class I Entry Certificate / Special Pass
A special pass allows a foreigner to begin work while a formal work permit application is processing. Valid for up to six months.
Class M Dependant's Pass
For spouses and dependants of work permit holders. Allows residence but not employment without a separate work permit.
Investors and business owners
Those investing in a Kenyan business can apply for a Class K investor's permit. Requirements include evidence of investment of at least $100,000 in a Kenyan enterprise.
Long-term residency and citizenship
Permanent residency in Kenya requires at least seven years of continuous legal residence. Citizenship is available after seven years of permanent residency, subject to government discretion. Dual nationality is generally not recognised under Kenyan law, though this has been subject to ongoing legislative debate.
Kenya's income tax system
Kenya operates an income tax system that taxes residents on worldwide income and non-residents on Kenyan-source income only.
Tax residency
You become a Kenyan tax resident if:
- You have a permanent home in Kenya and spend any time there in the year; or
- You are in Kenya for 183 days or more in a 12-month period starting or ending in a year; or
- You are in Kenya for more than 122 days on average over three years.
Income tax rates (PAYE)
Kenya's personal income tax rates as of 2026 (approximate — subject to annual budget):
- Up to KES 288,000/year (KES 24,000/month): 10%
- KES 288,001–388,000/year: 25%
- KES 388,001–6,000,000/year: 30%
- KES 6,000,001–9,600,000/year (KES 500,001–800,000/month): 32.5%
- Above KES 9,600,000/year (KES 800,000/month): 35%
The 32.5% and 35% top bands were introduced by the Finance Act 2023. Personal relief: KES 28,800 per year (KES 2,400 per month).
National Housing Levy and other deductions: several mandatory payroll deductions apply, including contributions to the National Housing Fund and the Social Health Insurance Fund (SHIF), which replaced the NHIF from 1 October 2024 (under the Social Health Insurance Act 2023). Verify current contribution rates as Kenya's social security framework has undergone significant reform.
Expat income considerations
Salary earned in Kenya for work performed in Kenya is subject to Kenyan PAYE. For expatriates on assignment with a foreign employer who seconded them to Kenya, the PAYE position may be more complex — Kenya's tax authority (KRA) will look at where the work is physically performed.
UK–Kenya Double Taxation Treaty
The UK and Kenya have a long-standing DTA. It allocates taxing rights between the two countries on employment income, dividends, interest, royalties, and capital gains. UK nationals receiving UK pension income or UK investment returns while resident in Kenya should take advice on the treaty application.
Cost of living in Nairobi
Nairobi has a bifurcated cost structure. The expat-oriented areas and lifestyle can be surprisingly expensive:
As of 2026 (approximate KES/GBP rate is highly variable — these are sterling equivalents at mid-2026 rates):
- Renting a 3-bedroom unfurnished house in Karen or Gigiri: approximately £2,000–£4,000/month.
- A modern apartment in Westlands or Kilimani: approximately £800–£1,500/month.
- International school fees (British curriculum): approximately £8,000–£18,000 per year depending on age and school.
- Private hospital consultations and procedures: significantly cheaper than UK private rates — a specialist consultation approximately £30–£80.
- Groceries: imported goods are expensive; local produce is very affordable.
- Domestic staff (housekeeper, gardener, driver): a standard part of middle-class expat life in Nairobi; monthly costs approximately £150–£400 per person depending on hours and role.
- Eating out: a wide range, from extremely affordable local restaurants to high-end international dining at prices approaching London levels.
Compound living
Many expat families live in gated compounds or secure developments in Karen, Runda, Gigiri, or Muthaiga. Security is a real consideration and most expats invest in secure housing and appropriate personal security measures as a standard lifestyle component.
Healthcare in Kenya
Nairobi has some of East Africa's best private hospitals. The Aga Khan University Hospital, MP Shah Hospital, Nairobi Hospital, and Karen Hospital provide good-quality care for routine and many specialist conditions. Medical standards are improving but for complex specialist care or serious emergencies, medical evacuation to South Africa (particularly Cape Town or Johannesburg) or Europe may be necessary.
Medical evacuation insurance is essential for expats in Kenya. Most IPMI policies covering Africa include evacuation cover; confirm that your policy includes East Africa explicitly and that the evacuation network includes Flying Doctors/AMREF and similar established operators.
Annual IPMI premiums for Kenya (comprehensive, including evacuation): approximately £2,000–£5,000 depending on age and coverage.
UK financial affairs from Kenya
- UK state pension: receivable in Kenya. Kenya is not on the UK's uprating agreement list — the state pension freezes at the rate applicable when you first become Kenyan resident. This is a material issue for long-term residents.
- UK private pensions: governed by the UK–Kenya DTA; SIPP drawdown to Kenya residents may be subject to UK withholding in the absence of treaty relief on specific pension types.
- UK rental income: always UK-taxable; Kenyan tax may also apply on worldwide income basis with treaty credit.
- UK investments: dividends and capital gains potentially subject to Kenyan tax; DTA credit provisions apply.
- UK ISAs: lose their UK tax-free status once non-UK resident.
Practical relocation steps
- Obtain the appropriate visa/work permit — coordinate with your employer or Kenyan immigration lawyer.
- Register with the Kenya Revenue Authority (KRA) for a PIN certificate (required for almost all financial transactions in Kenya).
- Open a Kenyan bank account (Equity Bank, KCB, Standard Chartered Kenya, and Barclays Kenya/Absa are popular choices; some offer specific expat banking services).
- Arrange comprehensive IPMI with medical evacuation cover.
- Arrange schooling — waiting lists for the most popular international schools can be long; apply early.
- Join the relevant expat community networks (British Chamber of Commerce in Kenya, your employer's assignee network, etc.).
- Notify HMRC of UK departure (P85).
Compliance caveat
Kenya's tax system has been subject to active reform and upward revision of rates and thresholds in recent budgets. The social security framework changed materially with the introduction of SHIF. Currency volatility between the Kenya shilling and sterling means that all KES-denominated thresholds fluctuate in sterling terms. Always take current professional advice. UK pension and investment planning in a DTA country context requires specialist cross-border expertise.
