AEW's European Research & Strategy team present their latest report focused on the European office market:
- Over the next five years, office-base employment growth in Europe is expected to slow as working-age population is projected to shrink and is only partly offset by continuing urbanisation.
- Despite increasing concerns over the impact of AI on office-based employment, early US data signals are not as clear-cut as media headlines suggest. However, initial European data shows that AI has a negative impact on tech companies’ hires.
- In the short term, European AI adoption and its impact on office employment will be limited by soaring AI costs, limited data centres computing capacity as well as sovereignty concerns triggering a need for local EU solutions.
- Office vacancy rates continued to increase in Q1 2026, including in CBD markets, as cost-conscious occupiers increasingly focus on more affordable non-CBD locations. However, with less new supply and an increasing number of office conversions, overall vacancy is projected to come down from its 9% peak mid-year 2026 to 7% by 2030.
- Average 2026-30 prime headline rental growth is expected to reach 3.9% p.a. across all 63 covered European office submarkets. These projections are expected to remain robust at 3.7% p.a. even in our downside scenario.
- While headline office rents have continued to grow, letting incentives (including free rent and tenant improvements) have increased in Europe since 2019. This is especially the case in peripheral non-CBD Paris and London markets, like La Défense and Docklands, where they reached near 40% of headline rents.
- 2026 office transaction activity has slowed down significantly since the start of the conflict in the Middle East due to higher financing costs and a renewed bid-ask spread as many buyers tried to renegotiate terms.
- With the negotiations continuing between the US and Iran to settle their conflict, oil prices and swap rates have stabilised somewhat. Assuming the peace process advances, a recovery in liquidity in H2 2026 could be expected.
- Office valuations reflect the ongoing bifurcation between best-quality offices having experienced increasing values, while offices facing structural vacancy and higher incentives have experienced significant value declines.
- The significant repricing recorded by the office sector in 2022-24 in combination with the near 4% p.a. expected rental growth, drive our latest prime office forecasts. Total returns are expected to reach 10% p.a. over the next five years across our 63 covered European markets.
