How Much Do Rental Void Periods Cost Landlords?

Rental void periods cost landlords the rent they would have received while a property is empty, plus ongoing expenses such as mortgage payments, council tax, utilities, insurance and maintenance. A landlord charging £1,250 per month could lose roughly £288 from a one-week void or £577 from a two-week void, before considering these additional costs.

Reducing the length and frequency of voids can therefore make a meaningful difference to annual rental returns.

Key Takeaways:

• A rental void period is the time when a rental property is unoccupied and generating no rent.

• A one-week void on a property renting for £1,500 per month represents approximately £346 in lost rental income.

• Mortgage payments, council tax, insurance, utilities and maintenance may continue while the property is empty.

• Competitive pricing, strong presentation, and efficient marketing can help reduce avoidable void periods.

• Keeping reliable tenants for longer can reduce the number of changeovers a landlord needs to manage.

• Guaranteed rent may be worth considering for landlords who prioritise predictable rental income.

A rental property can be performing well for most of the year, yet a few empty weeks between tenants can still reduce its annual return.

The reason is simple: rental income stops during a void period, while many property costs continue.

So, how much do rental void periods cost landlords? The answer goes beyond the missing rent. Mortgage payments, council tax, utilities, maintenance and other expenses can continue until the next tenancy begins.

The impact becomes clearer when you compare it with actual numbers. With average private rent in Southampton reaching £1,255 per month in July 2026, even relatively short gaps can represent hundreds of pounds in missed rental income.

Here is what landlords should consider when calculating the real cost of a rental void, and how they can potentially reduce it.

What Is a Rental Void Period?

A rental void period is the time a rental property is unoccupied between tenancies, when the landlord receives no rental income. Voids commonly occur when one tenant leaves, and there is a gap before the next tenant moves in.

Government rent officer guidance similarly describes voids as periods when a property is empty between separate lettings, during which landlords can lose rental income while finding another tenant.

For example, a tenancy may end on 31 March, but the replacement tenant may not move in until 15 April. Those two weeks are the property's rental void period.

Voids can happen because a landlord needs time to:

• Find and reference new tenants.

• Complete repairs or maintenance.

• Prepare and clean the property.

• Complete administrative work.

• Wait for a suitable tenant to become available.

Some gaps are difficult to avoid completely. The important question is how frequently they occur, how long they last and how much they cost.

How Much Do Rental Void Periods Cost in Lost Rent?

The easiest way to estimate how much rental void periods cost in lost income is to calculate the property's annual rent and divide it by 52 for an approximate weekly figure. This quickly shows why even a one- or two-week gap matters.

Here are some examples:

Monthly Rent	1 Week Void*	2 Week Void*	1 Month Void
£1,000	~£231	~£462	£1,000
£1,250	~£288	~£577	£1,250
£1,500	~£346	~£692	£1,500
£2,000	~£462	~£923	£2,000

Approximate figures based on annual rent divided by 52 weeks.

For example, take a property generating £1,500 per month.

That produces £18,000 in gross rent over a full 12 months. A two-week void reduces the year's potential rental income by approximately £692.

A full month's void means £1,500 in missed rent.

For context, the latest ONS data puts Southampton's average private rent at £1,255 per month as of July 2026. At that level, a two-week void represents roughly £579 in potential lost rental income.

However, lost rent is only one part of the cost of rental void periods.

The Hidden Costs of Rental Void Periods

Lost rental income is only one part of a void's financial impact. Landlords may continue paying several property-related expenses while receiving no rent, meaning the real cost of an empty property can be higher than the rental income calculation alone suggests.

Depending on the property and circumstances, ongoing costs can include:

• Mortgage payments: Financing costs do not stop because the property is temporarily empty.

• Council tax: Landlords may become responsible for council tax during an empty period. GOV.UK states that council tax will usually still be payable on an empty home, although individual councils can decide whether a discount applies.

• Utility charges: Standing charges or other utility costs may continue even with minimal usage.

• Insurance: Landlords should check their policy conditions when a property becomes unoccupied, particularly for longer void periods.

• Maintenance and repairs: A changeover may reveal repairs or maintenance that need completing before another tenant moves in.

• Service charges: Leasehold properties may continue attracting service charges regardless of occupancy.

• Marketing and tenant-finding: Advertising, viewings, referencing and other costs involved in securing the next tenant can add to the total.

This is why landlords should calculate the true cost of a rental void based on lost income plus continuing expenses, rather than looking at rent alone.

Why Do Rental Properties Have Void Periods?

Rental properties experience void periods for several reasons, ranging from normal tenant changeovers to pricing, maintenance and marketing delays. Understanding the cause helps landlords identify which gaps are unavoidable and which they can shorten.

Common causes include:

1. Tenant changeovers

Even with strong demand, some time may be needed between one tenancy ending and another beginning.

2. Rent set above the local market

Setting the highest possible asking rent does not automatically produce the best annual return. If an additional £50 per month results in several extra weeks without a tenant, the lost income may outweigh the higher rent.

3. Poor property presentation

First impressions matter. A poorly presented property can make it harder to attract suitable tenants quickly.

4. Maintenance or refurbishment delays

Repairs, decorating and compliance work can extend the period between tenants when they are not planned in advance.

5. Slow marketing

Waiting until a property is empty before looking for the next tenant can create an unnecessary gap.

6. Seasonal and local demand

Rental demand can vary by location, property type, and time of year.

7. Referencing and administration

Tenant referencing, paperwork and move-in arrangements all take time. Inefficient processes can add extra days to a changeover.

How Can Landlords Reduce Rental Void Periods?

Landlords can reduce rental void periods by planning tenant changeovers early, pricing the property appropriately, maintaining it well and making the letting process efficient. The goal is not simply to fill a property quickly, but to attract suitable tenants while avoiding preventable delays.

Here are seven practical areas to focus on:

1. Start planning early. Where appropriate, prepare for marketing before the existing tenancy ends rather than waiting until the property is empty.

2. Set a competitive rent. Look at comparable local properties and current market conditions when deciding the asking rent.

3. Keep the property well maintained. A clean, attractive and properly maintained rental is generally easier to present to prospective tenants.

4. Deal with repairs promptly. Leaving repairs until a tenant moves out can unnecessarily extend the changeover period.

5. Encourage good tenants to stay. Longer tenancies mean fewer changeovers, reducing opportunities for void periods.

6. Use experienced property management. Effective tenant communication, maintenance coordination and day-to-day management can help keep a tenancy running smoothly. Moorhouse's guide to property management companies in Southampton explains how professional management can support landlords with tenant management, rent collection, repairs, inspections and other ongoing responsibilities.

7. Budget for unavoidable gaps. Even well-managed properties can experience voids. Building an allowance into your financial planning makes an occasional empty period easier to absorb.

The aim should be sustainable occupancy rather than simply choosing the first available tenant.

Can Guaranteed Rent Protect Landlords From Void Periods?

Guaranteed rent arrangements can offer an alternative for landlords who prioritise predictable monthly rental income, depending on the terms of the specific agreement. Rather than relying entirely on reducing each individual void, the focus shifts towards greater income predictability.

Reducing void periods can help protect rental returns, but it may not remove the risk completely. For landlords who prioritise predictable monthly income, a guaranteed rent arrangement may provide an alternative.

This can be particularly relevant for property investors viewing their portfolio through a cash-flow lens. Rental yield on paper is useful, but the income received throughout the year ultimately matters.

Landlords considering their wider investment strategy can also read Moorhouse Property Services' guide on how to source property for investors, which covers evaluating local markets, rental rates and investment opportunities.

Before entering any guaranteed rent arrangement, landlords should review exactly what is covered, how payments work, who is responsible for management and maintenance, and the full contractual terms.

FAQs About the Cost of Rental Void Periods

How much does a one-week rental void cost?

The amount depends on the rent. A property renting for £1,000 per month loses approximately £231 in rental income over one week, while a £1,500-per-month property loses approximately £346. Additional ongoing expenses can increase the real cost.

How do you calculate the cost of a rental void?

For an approximate weekly figure, multiply the monthly rent by 12, then divide by 52. Then multiply the weekly figure by the number of weeks the property is empty. Add ongoing expenses during the period for a more complete estimate.

What costs do landlords pay during a rental void period?

Depending on the property and circumstances, landlords may still need to cover mortgage payments, council tax, utility standing charges, insurance, maintenance and service charges while the property is empty.

Can rental void periods be completely avoided?

Not always. Tenant changeovers, repairs and market conditions can create unavoidable gaps. Good planning, competitive pricing, property maintenance and efficient tenant management can help reduce their frequency and duration.

Is guaranteed rent worth considering if I am worried about void periods?

It may be worth exploring if predictable rental income is a priority. The suitability of guaranteed rent depends on the property, expected returns and the specific terms offered, so landlords should compare the arrangement with conventional letting and management options before deciding.

Reduce the Cost of Rental Void Periods

Rental void periods can cost landlords more than a few weeks of missing rent. Once you factor in mortgage payments, council tax, utilities, insurance, maintenance, and tenant-finding expenses, even a short gap can affect annual returns.

Planning ahead can make those gaps easier to manage.

Competitive pricing, timely maintenance, strong tenant relationships and efficient property management can all help reduce avoidable void periods. For landlords seeking more predictable rental income, guaranteed rent may be another option.
