A finance director at a mid-sized tech company told us last year that switching to lump sum relocation had been “the easiest decision of the year.” Fixed cost, no negotiation with vendors, no managing invoices from three different service providers. The employee gets a cheque. The company moves on.

Eight months later, the same employee was back in his home country. The relocation hadn’t failed because of the money. It failed because nobody had told him that finding a flat in Lyon in September – when the rental market is at its tightest point of the year – takes three weeks of full-time effort, and he’d tried to do it over weekends while starting a new job.

This is the conversation HR teams in France are having more and more. Not “should we do lump sum or not” – that decision has often already been made. The real question is: what happens after the cheque is sent?

What lump sum actually means, and why it’s spreading

A lump sum relocation package is a fixed amount of money given to an employee to manage their own move, instead of the company coordinating (and paying for) each service individually – housing search, school enrolment, visa support, settling-in assistance.

The appeal for companies is straightforward. According to a 2025 Worldwide ERC mobility survey, 68% of companies now offer lump sum options for at least some categories of relocation, up from 54% in 2021. The reasons cited most often: predictable budgeting, reduced administrative load, and a perception that employees prefer the flexibility and the cash.

That last point is partly true. Employees who relocate frequently, who are young, single and have done this before, often genuinely prefer lump sum. They know the market, they know what to prioritise, and an unspent portion of the lump sum effectively becomes a bonus.

The problem is that this profile – experienced, single, mobile – is not the average relocating employee. It’s a minority.

Where lump sum quietly fails

Here’s what doesn’t show up in the budget spreadsheet.

A family relocating with school-age children needs to coordinate a housing search with a school enrolment timeline, often across two parents’ schedules and sometimes across two languages. Doing this alone, while also starting a new role, is not a flexibility problem – it’s a bandwidth problem. Something gives. Usually it’s either the quality of the housing decision (rushed, wrong neighbourhood, regret within six months) or the employee’s first few months of performance (distracted, stressed, present but not really there).

We’ve seen both outcomes repeatedly. A pharmaceutical group we worked with in 2024 had moved to a lump sum model for all relocations under a certain seniority level. Within 18 months, they noticed something in their retention data: employees who had relocated under lump sum were leaving within the first 18 months at nearly double the rate of those who’d had a managed relocation. The HR team’s working theory, confirmed by exit interviews, was simple – the relocation experience itself had coloured the employee’s overall impression of the company, before they’d even properly started.

There’s also a more mundane failure mode: employees who simply don’t spend the money on what it was intended for. A lump sum earmarked for housing support sometimes goes toward paying down debt, a larger car, or simply gets absorbed into daily expenses because there’s no visible link between “this money” and “this specific problem to solve.” Then, three weeks before the start date, the employee is searching for a flat with a much smaller effective budget than the company calculated.

The hybrid model: what’s actually working

The companies getting the best results in 2025 and 2026 aren’t choosing between lump sum and full management. They’re combining both – and the split point matters.

The model we see working most consistently: a lump sum covers discretionary costs (temporary accommodation extension, furniture, settling-in expenses, school supplies) while housing search and the core administrative process (visa, social security registration, school enrolment support) remain professionally managed.

Why this split specifically? Because the discretionary items are where individual preference genuinely matters and where flexibility is a real benefit – some employees want to spend more on furniture and less on temporary housing, or vice versa. But the housing search and administrative steps are where local market knowledge, time availability and process familiarity make the difference between three weeks and three months.

According to a 2024 internal benchmark we conducted across our corporate clients, companies using this hybrid approach reported relocation-related attrition (employees leaving within 24 months, citing relocation difficulties as a contributing factor) at roughly half the rate of companies using pure lump sum models for the same employee categories.

Half. For a company relocating even a modest number of employees per year, that difference compounds quickly – both in direct replacement costs and in the harder-to-measure cost of a bad first impression with a new hire’s family.

What this means for your 2026 mobility policy

If your company already uses lump sum and it’s working, this isn’t a call to abandon it. For certain employee profiles – experienced single relocators, short-term assignments, employees who’ve relocated before – lump sum genuinely is the right tool.

The question worth asking before your next policy review: does your lump sum amount assume the employee will spend 100% of their non-working hours for three weeks managing logistics? Because that’s often what the math implicitly requires. If the answer is yes, and your relocating population includes families, first-time movers, or people relocating to cities they don’t know, the gap between the budget and the reality is where things go wrong.

A simple diagnostic: look at your relocation-related attrition over the last 24 months, segmented by whether the employee used lump sum or managed relocation. If you don’t currently track this segmentation, that’s worth fixing before your next budget cycle – it’s the single most useful number for deciding where the line between “cash” and “managed support” should sit.

We work with HR and mobility teams across France to design hybrid relocation policies that keep the budget predictability companies want while keeping the support where it actually changes outcomes. If you’d like to talk through what this could look like for your organisation, get in touch with our corporate team – no commitment, just a conversation about what’s working and what isn’t in your current policy.

Expat Services France has supported corporate mobility programmes since 2009, working with HR teams at companies to design relocation policies that hold up in practice, not just on paper.
