Offshoring vs Nearshoring vs Onshoring: A Location Guide for UK Companies
Many location decisions go wrong in the first conversation, because the room is arguing about two different questions at once. Outsourcing is a question about who does the work. Offshoring, nearshoring and onshoring are questions about where it happens. They are independent choices, and treating them as one produces false trade-offs that narrow the options before anyone has looked at the facts.
This guide separates the two, defines each location model precisely, sets out what counts as nearshore or offshore for a UK company specifically, and gives you a framework for choosing based on the function rather than the hourly rate.
In short: Outsourcing is about who does the work. Offshoring, nearshoring and onshoring are about where it happens. You can offshore without outsourcing, and outsource without leaving the UK. For most UK mid-market firms the practical decision is the right combination of locations, and the single most useful filter is time-zone overlap rather than hourly rate.
What is the difference between outsourcing and offshoring?
Outsourcing means contracting work to a third party instead of doing it with your own employees. It says nothing about geography. Offshoring means moving work to another country. It says nothing about who employs the people.
The two combine in all four possible ways, and each is a real option. You can outsource onshore, by contracting a firm in Manchester. You can outsource offshore, by contracting a provider in India. You can offshore without outsourcing, by opening your own centre in Cape Town or building an embedded team that works for you. And of course you can keep everything in-house and onshore. Recognising these as separate decisions is what stops a board conversation collapsing into "should we outsource or not", when the real question is usually which combination fits which function.

Onshoring, nearshoring, offshoring and reshoring defined
| Term | Definition | For a UK company |
|---|---|---|
| Onshoring | Placing work in your own country, whether in-house or contracted to a domestic firm | Anywhere in the UK |
| Nearshoring | Placing work in a nearby country, usually in the same or a close time zone | Romania, Poland, Portugal, Spain, and similar |
| Offshoring | Placing work in a distant country, typically for cost and talent access | India, South Africa, Philippines, Brazil |
| Reshoring | Bringing work back to your own country after it was moved abroad | Returning a function to the UK |
One nuance is worth pausing on, because it is the single most useful thing in this guide for a UK business. South Africa is offshore by distance but behaves like nearshore in practice. Cape Town and Johannesburg are one hour ahead of the UK in British Summer Time and two in winter, so a 9 to 6 day there runs from 8am to 5pm UK time in summer and 7am to 4pm in winter, covering most of the UK working day, with a deep pool of English-speaking professionals. If you filter locations by "nearshore" on a map you will exclude it, and for most UK companies that would be a mistake.
How do the locations compare?
| Location | UK overlap | Typical saving and baseline | Strongest for |
|---|---|---|---|
| UK (onshore) | Full | Baseline | Client-facing leadership, regulated sign-off, work needing constant in-person contact |
| Romania, Poland (nearshore) | Near-full: 2 hours ahead all year (Iași: 7am to 4pm UK time) | In Iași, labour costs typically 40 to 50% below Western European rates | EU-facing work, multilingual support, engineering, EU regulatory alignment |
| South Africa | Near-full: 1 hour ahead in summer, 2 in winter (8am to 5pm UK time in summer, 7am to 4pm in winter) | In Cape Town and Johannesburg, labour costs typically 30 to 50% below the UK | Customer service, BDRs, SDRs, finance, analytics, work needing real-time collaboration in English during the UK day |
| India | Your morning: 4.5 hours ahead in summer, 5.5 in winter (4.30am to 1.30pm UK time in summer, 3.30am to 12.30pm in winter) | In Bengaluru, salaries often 40 to 70% below the UK, especially for mid-to-senior roles | Data engineering, analytics, technical depth, early-morning cover; anything beyond is agreed with you case by case |
| Brazil | Your afternoon: 4 hours behind in summer, 3 in winter (1pm to 10pm UK time in summer, 12pm to 9pm in winter) | In São Paulo, operating costs for equivalent roles typically 30 to 50% below the UK | Americas coverage, engineering and data talent, time-zone diversification |
The savings in the table are our own experience, measured on different bases, so they do not rank the locations against each other. Talent depth varies by discipline as well as by country, which is why the function, and the hardest role in it, should drive the choice.
Why time-zone overlap matters more than hourly rate

Overlap determines how the team can actually be used, and it is the constraint people most often underestimate. With near-total overlap, the team joins your stand-ups, answers your customers in real time and asks a question the moment they are stuck. With partial overlap, you get a few hours of live collaboration and the rest runs asynchronously, which is excellent for defined work and awkward for anything needing constant back-and-forth. With opposite shifts, you gain genuine overnight cover but lose spontaneous collaboration almost entirely.
None of those is wrong. They suit different work. The mistake is picking a location on rate and then discovering the collaboration model you assumed is not available. Decide what overlap the function actually needs first, then look at cost within the locations that provide it.
Why the cheapest rate is rarely the lowest total cost
Headline hourly rates are the most visible number and the least complete. Three things routinely close the gap between a cheaper location and a slightly more expensive one.
Management overhead. A team you can reach for six hours a day needs less structure, documentation and chasing than one you can reach for two. That difference is real work, usually done by your most expensive people.
Attrition and rework. A cheaper market with high churn can cost more once you count repeated onboarding and the quality dip that follows each departure. Retention is an economic variable.
Rework from miscommunication. Where language or cultural alignment is weaker, more work comes back. It rarely appears in a business case and reliably appears in a delivery schedule.
What about data protection and compliance?
If your team will handle personal data, location affects your obligations under UK GDPR. Sending personal data to, or making it accessible to, a separate organisation outside the UK is a restricted transfer, and the ICO's guidance on international transfers sets out how to identify one and what to put in place.
In practice, EU locations such as Romania and Poland are the simplest for a UK business, because UK adequacy regulations cover the EEA, so no IDTA or transfer risk assessment is needed, though your other UK GDPR duties still apply. South Africa, India and Brazil are not covered by UK adequacy, so transfers there ordinarily need an appropriate safeguard, such as the International Data Transfer Agreement or the Addendum, together with a transfer risk assessment, unless one of the narrow UK GDPR exceptions applies. South Africa's POPIA is closely aligned with GDPR principles, which helps the assessment but does not remove the requirement. Take advice on your own data flows. None of this rules any location out; it simply needs designing at the start rather than discovered at a security review.

Which location suits which function?
| Function | Best fit | Deciding factor |
|---|---|---|
| Customer service and sales | South Africa | English-first plus real-time overlap with your customers' day |
| Finance, accounting, back office | South Africa or Romania | Overlap for month-end, and EU alignment where relevant |
| Data engineering and analytics | India | Depth of specialist skills; work is well-defined and async-friendly |
| Multilingual EU support | Romania | Language coverage and EU regulatory alignment |
| Early-morning or evening cover | Bengaluru for UK early mornings, São Paulo for evenings, or multi-hub | Time-zone offset is the point; anything beyond is agreed with you case by case |
| Regulated sign-off, senior client relationships | Keep onshore where regulation or the relationship needs UK presence | Accountability and presence can outweigh cost |

Working out where your team should sit?
Potentiam runs teams across five hubs in four countries, so we can talk through the trade-offs for your specific function rather than selling you one location.

Framing this as a single choice is itself the error. Different functions have genuinely different requirements, and once you have more than one function offshore, one location will suit one and compromise another.
A multi-hub arrangement lets you put customer service where the overlap is best, data work where the specialists are, and EU-facing work inside the EU. It also gives you resilience: if one location is disrupted by weather, infrastructure or local conditions, work can shift rather than stop, provided the teams are cross-trained, have the access they need and have a tested continuity plan. And it avoids concentration risk in a single labour market, currency or jurisdiction. This is the approach behind the embedded offshore team model, and it is why we operate five hubs in four countries rather than one.
When does it make sense to bring work back?
Reshoring gets less attention than the outbound decision, but it happens often enough to be worth understanding, and the reasons are usually instructive. Work tends to come back for one of three causes: the total cost turned out higher than the rate implied once management overhead and rework were counted; quality or customer experience suffered in a way that damaged the brand; or the function became more strategic than it was when the decision was made, and the business wanted it close again.
Notice that only the first of those is really about location. The other two are usually about model rather than geography. A function that suffered under a price-led, arm's-length arrangement will often work perfectly well offshore when it is run as a dedicated team inside your own processes. Before reshoring on quality grounds, it is worth asking whether the problem was the country or the structure, because moving the work back to the UK is an expensive way to fix a governance issue.
Where reshoring genuinely is the right answer, it is usually for work that has become regulated, client-facing at a senior level, or so tightly coupled to in-person decision-making that any distance hurts. Those are real cases, and they are narrower than the general anxiety about offshoring would suggest.
How to run the decision in practice
A workable sequence, and deliberately not the one many companies follow. First, define the function precisely, including what good looks like and how you will measure it. In our experience, vague scope is the most common cause of a disappointing outcome, whatever the location. Second, decide the overlap you actually need, honestly: how many hours of live collaboration does this work genuinely require? Third, shortlist locations that satisfy that constraint, and only then look at cost within the shortlist.
Fourth, check the compliance path for the data involved before you commit, not after. Fifth, decide the operating model, meaning who employs, who manages, and where the knowledge accumulates, which matters at least as much as the country. Finally, start narrow. One well-defined workload, measured properly, teaches you more about whether a location and model suit you than any amount of comparison. Extending afterwards is straightforward once the operating rhythm exists.
Five mistakes to avoid
The common traps
1. Choosing on hourly rate before deciding what time-zone overlap the function needs. 2. Assuming all offshore locations are interchangeable, when talent depth varies enormously by discipline. 3. Underestimating management load, particularly with limited overlap. 4. Leaving data-transfer compliance until the security review. 5. Treating the decision as permanent, when most companies revise it as functions grow.
Where Potentiam fits
Five hubs, chosen per function
We build and run embedded offshore teams across five hubs: Cape Town and Johannesburg in South Africa, Iași in Romania, Bengaluru in India and São Paulo in Brazil, with offices, local management and an embedded HR business partner. Because we operate in all four countries, we can recommend the right hub for the function rather than the one we happen to have. Our founders scaled an energy procurement business to more than 300 people, about 60 per cent of them offshore, before its acquisition by Accenture in 2015. You can read more about our story, or compare delivery models in our guides to recruitment and staffing agencies and Employer of Record services.
Frequently asked questions
What is the difference between outsourcing and offshoring?
Outsourcing is about who does the work: contracting it to a third party rather than using your own employees. Offshoring is about where the work happens: moving it to another country. They are independent, so you can outsource within the UK, or offshore without outsourcing by building your own team abroad.
What is nearshoring, in simple terms?
Nearshoring means placing work in a nearby country, usually one in the same or a close time zone. For a UK business that typically means Romania, Poland, Portugal or Spain. The appeal is a balance: lower cost than onshore, with easier collaboration, shorter travel and closer cultural and regulatory alignment than a distant location.
Is South Africa nearshore or offshore for a UK company?
Technically offshore by distance, but it behaves like nearshore for working-hour overlap and English-language collaboration. Cape Town and Johannesburg are one hour ahead of the UK in British Summer Time and two in winter, so a 9 to 6 day there runs from 8am to 5pm UK time in summer and 7am to 4pm in winter, and there is a deep pool of English-speaking professionals. If you are filtering locations by geography alone you will miss it, which is why we would encourage judging locations on overlap and language rather than distance.
Is nearshoring more expensive than offshoring?
Not necessarily: headline rates depend on the role, seniority, location and employment model, so compare like with like. Whether one is more expensive in total depends on the function. Where work needs frequent real-time collaboration, the extra overlap can reduce management overhead and rework enough to close the gap. Where work is well-defined and can run asynchronously, the cheaper location often does keep its advantage.
Can we use more than one location?
Yes, and in our experience most companies with several offshore functions eventually do. Different functions have different requirements, so one location will suit one and compromise another. A multi-hub approach also spreads risk across labour markets, currencies and jurisdictions, and enables extended-hours coverage without paying UK out-of-hours rates.
What are the data protection implications of offshoring?
Sending personal data to, or making it accessible to, a separate organisation outside the UK is a restricted transfer under UK GDPR, as the ICO's international transfer guidance explains. EU locations such as Romania are simplest because UK adequacy regulations cover them. South Africa, India and Brazil ordinarily need an appropriate safeguard, such as the International Data Transfer Agreement, plus a transfer risk assessment, unless a narrow exception applies; South Africa's POPIA is closely aligned with GDPR principles, which helps. The important thing is designing data access and transfer arrangements at the outset rather than retrofitting them.
