The Real Cost of Vacant Commercial Property in 2025

In today's challenging market, commercial properties remaining unoccupied are not just idle — they're a growing liability. For landlords and asset owners, the key cost driver is not only lost rental income but the looming burden of full business rates once the void relief period expires. Understanding how the rules work — and how compliant solutions such as those offered by VacatAd can help — is increasingly critical.

Understanding the 'empty property' relief window

Under the current rules in England, a vacant non-domestic property typically benefits from a 100% relief from business rates for the first three months of vacancy. After that, full business rates are payable. For industrial and warehouse uses the exemption may extend to six months in some cases. Crucially, for a new three-month relief period to begin after the first one ends, the property must be re-occupied for at least 13 weeks (i.e., a reset).

Key Insight: The 13-week reset rule is critical. Without genuine occupation for this period, landlords cannot restart the relief clock and will continue to pay full business rates on empty property.

Why this matters now

For many property owners the risk is clear:

Rents are under pressure, meaning vacancies may last longer.
After the relief period expires, full business rates apply even if the unit remains empty — meaning a cost with no income.
Councils and the Valuation Office are increasingly scrutinising "mitigation" strategies and beneficial occupation arguments. For instance, a recent commentary notes that local authorities view short‐term or token occupation purely to reset relief periods as at risk of being challenged.

As occupancy durations shorten, and market demand weakens, the pressure to adopt compliant, efficient solutions to manage financial burden rises.

How compliance and mitigation intersect

The concept of "beneficial occupation" is central here. Under longstanding rating law, for occupation to count (i.e., be rateable), it must be:

actual occupation;
exclusive to the possessor for the purposes of the possessor;
of benefit to the possessor; and
not too transient in nature.

A simplistic "lease for a few weeks just to restart the clock" may fail the test if the sole or predominant purpose is rates avoidance rather than a genuine use of the property.

For landlords of empty units, this means: any solution involving occupation must be defensible, documented and consistent with the law. It is here that VacatAd's model — installing a live-public Wi-Fi node, delivering local advertising, and thereby generating a genuine public benefit and occupation — positions itself as a compliant strategy rather than a loose workaround.

Practical steps for landlords

Inventory your void properties – Record each site's vacancy start date and relief expiry.
Understand the reset rule – If you aim to take advantage of another relief window, ensure the unit is genuinely occupied for at least 13 weeks and that the occupation is defensible.
Assess cost vs benefit – The cost of business rates for a vacant unit may exceed the cost of installing a compliant occupation solution by some margin.
Monitor local authority stance – Some authorities are signalling a tougher approach to mitigation; ensure any strategy is robust, documented and transparent.
Consider value beyond rates – Visibility, community benefit and reputational uplift can accompany compliant occupation schemes — which aligns with VacatAd's value proposition.

Why this is strategic, not just tactical

This is not merely a cost-management issue. The presence of long-term vacant property can:

impact asset valuations;
undermine local high-street vitality (which in turn can influence leasing prospects);
expose owners to reputational risk and regulatory challenge.

By proactively managing void periods, aligning with legal requirements, and embedding value-adding activities (such as local advertising or community connectivity), property owners can turn a liability into a strategic advantage.

Conclusion

Vacancy on a commercial property no longer simply means "waiting for the next tenant". It means navigating a month-by-month cost regime, with business rates easily stacking up once relief periods expire. But with the right approach — one that respects the principles of beneficial occupation and leverages compliant solutions like VacatAd's connectivity-led model — the risk can be managed. In 2025, failing to act is not just passive; it's expensive. As landlords and asset owners, the time to review your vacant-portfolio strategy is now.
