What Is a Void Period and When Does It Happen?
A void period is any period when a SIPP-owned commercial property is vacant — generating no rental income. Voids can arise in several circumstances: the lease expires and a new tenant has not yet been found, a tenant defaults and leaves, a tenant exercises a break clause, or the property becomes unlettable due to condition or market changes.
Void periods are a normal part of commercial property investment, but they carry particular significance for a SIPP. Without rental income, the fund must still meet its ongoing obligations: buildings insurance, business rates, utility costs (if applicable), and any SIPP mortgage repayments. If the fund does not have sufficient cash reserves to meet these costs, the pension holder may need to make additional contributions — though these must respect annual allowance limits.
Planning for void periods is part of prudent SIPP property management, not an edge case. Before purchasing a property, consider how the fund would cope with a six-month or twelve-month vacancy.
Insurance Requirements When the Property Is Empty
Standard commercial buildings insurance policies impose significant restrictions when a property becomes vacant. Most policies define a threshold — typically 30 or 45 consecutive days — after which vacant property exclusions apply. These typically exclude cover for:
- Malicious damage and vandalism
- Water damage from burst pipes
- Theft (of fixtures and fittings)
- Accidental damage
When a SIPP property becomes vacant, notify your insurer immediately and switch to a specialist vacant commercial property policy. These are more expensive than standard occupied property insurance and typically require regular property inspections (every 7–14 days) to maintain cover. Failure to notify your insurer of a vacancy and switch cover could result in a claim being denied at a time of maximum need.
As discussed in our guide to SIPP property insurance, the SIPP provider must be kept informed of changes in the property's status.
Business Rates on Empty Commercial Property
Business rates continue to be payable on vacant commercial properties, subject to a limited exemption. Empty commercial buildings are exempt from business rates for the first three months of vacancy (six months for industrial and warehouse properties). After this period, business rates are payable at the full standard rate.
This is a significant cost to factor into void period planning. On a property with a rateable value of £30,000, business rates after the free period would be approximately £15,000 per year at current multipliers — payable by the SIPP fund. These costs can be met from SIPP fund assets.
Some strategies can legitimately manage business rate liability during a void — periodic occupation by a short-term tenant or licence holder can restart the three-month exemption. Your commercial property solicitor or rating surveyor can advise on lawful approaches to rate mitigation.
Mortgage Implications of a Void Period
If the SIPP holds a mortgage on the property, the lender's standard conditions will typically include obligations around occupancy. Most SIPP mortgage lenders require that the property is let to a creditworthy tenant on commercial terms and will need to be notified if the property becomes vacant.
A prolonged vacancy — particularly one that leads to missed mortgage payments — can trigger default provisions in the mortgage. Lenders are not unsympathetic to short void periods, which are a normal feature of commercial property investment, but they will want to understand the situation and your plan to relet.
If you anticipate a void period in advance — for example, if your lease is approaching expiry — speak to your broker and lender early. Proactive communication is far better received than a lender discovering the issue from a missed payment or a property inspection.

Strategies for Minimising and Managing Voids
The best approach to void periods is to minimise their likelihood and duration through proactive management:
- Start remarketing early: Begin marketing a property for relet 12 months before lease expiry or a known break date. Commercial property searches and negotiations take time, and starting early gives you the best chance of continuity.
- Maintain the property well: A property in good condition is easier and faster to let than one requiring significant work. Regular maintenance during the tenancy pays dividends at reletting.
- Consider short-term licences: For shorter void periods, a licence to occupy (as opposed to a lease) can generate some income while you find a long-term tenant, and can restart the business rate exemption period.
- Price realistically: Overpricing a vacant property extends the void. Regular review of the asking rent against comparable market evidence keeps you competitive.
- Maintain cash reserves in the SIPP: Holding sufficient liquid assets in the fund to cover 6–12 months of void costs provides a buffer that removes the pressure to accept a weak tenant or disadvantageous lease terms.
