7 Costly Oversights Landlords Should Fix Between Tenancies

Managing a UK rental property is more than just a way to make money. It’s a business where each day without a tenant costs you money.

Many property owners see the time between tenants as simply getting someone new in. Still, the best investors see it as a key opportunity to assess their property.

Recent data shows that about 25% of UK tenants move each year. This means if you do not check your property during these times, small issues can turn into expensive issues.

By changing your approach from just cleaning to a thorough property review, you can protect your rental income and maintain long-term profit.

We, at A Hint of Mint, help you through these transitions by offering specialised tenant placement and maintenance management to help keep your property’s value.

Expensive Oversights Landlords Should Fix Between Tenancies

Here are the seven expensive oversights landlords should fix between tenancies:

  • Update Access Control and Security

Security is crucial for a successful rental. When a tenant returns the keys, the property is likely secure. However, keys can be lost, poorly tracked, or duplicated without your knowledge over time.

Access control is often assumed to be secure if no problems were reported during the previous tenancy. However, specialists at Barry Bros Security note that rental properties frequently carry forward unreturned key copies, unchanged alarm codes or outdated entry systems. Addressing access control between tenancies is typically far less costly than responding to a preventable security incident later.

In addition to changing the locks, check the physical condition of the entry points. Make sure window locks operate smoothly and that the front door has the latest insurance standards for multi-point locking systems. If your property uses a digital entry code or a shared gate, resetting these codes is a must.

This practice secures the building and gives your new tenant peace of mind. It shows that you care about their safety and the protection of your property.

  • Audit Hidden Damp and Ventilation Sources

Damp and mould are common problems that can lead to legal concerns and delays in getting back deposits in the UK rental market. Many landlords try to fix these problems with a quick clean and fresh coat of paint.

However, this only masks a deeper issue that will likely resurface within weeks of a new tenant moving in. Use the downtime to identify the root cause.

According to a recent report, approximately 12% of private rented homes in England do not meet the Decent Homes Standard because of damp and mould. This problem poses a financial risk for landlords, as failing to meet these standards can lead to significant rent repayment orders and necessary repair costs.

Check if overgrown gardens block air bricks or if the previous tenant has closed off the trickle vents in the windows.

Extractor fans in bathrooms and kitchens help prevent moisture buildup. Over time, these fans can stop working or get clogged with dust. To check if they work, turn them on and feel for airflow.

If a fan is noisy or weak, replace it now. Regular maintenance of ventilation systems is much deeper than hiring a mould removal team or dealing with a local authority notice for improvement.

  • Test Appliance Longevity and Energy Efficiency

Appliances can often cause frustration during a tenancy. A broken washing machine or fridge can lead to emergency fees and unhappy tenants.

When you turn over a property, don’t just check if the appliance works. Look closely at the seals on the oven and fridge to ensure they are airtight. A damaged seal makes the appliance work harder, increasing energy bills and shortening its lifespan.

Energy efficiency is critical. If an appliance is old, replace it with an A-rated model. This reduces the opportunity of breakdowns and helps your property attract cost-conscious tenants. Efficient homes draw in stable, long-term renters who are less likely to struggle with utility costs.

  • Review Documented Compliance Evidence

Compliance is crucial for your protection as a landlord. You probably know about Gas Safety Certificates and Electrical Installation Condition Reports.

However, it’s often the smaller details that get overlooked. Inspecting the expiration dates on your smoke alarms and carbon monoxide detectors is an important step that many people forget. These devices usually last 7 to 10 years, and you need to replace them fully when they reach the end of their lifespan.

Make sure all your documents are up to date and easily accessible. Between tenants, create a physical or digital compliance pack for the new tenant. Providing proof of a recent boiler service and a legionella risk assessment shows you are a responsible landlord. This openness builds trust from the start and ensures that if a local authority inspector asks for records, you can provide them quickly and without stress.

  • Assess Exterior and Drainage Integrity

Landlords frequently pay close attention to the inside of a property because that’s what tenants see during a viewing. However, the building’s outside is crucial for keeping the inside dry and profitable. Clogged gutters can cause serious damp issues. If leaves and debris pile up, water will overflow and seep into the bricks or soak the fascia boards.

Quickly reviewing your downpipes and drains can help prevent serious water damage. Look for cracks in the render or spots where the ground level is higher than the damp proof course. These problems can hurt your property value.

Fixing a leaking gutter is much cheaper than repairing internal plasterwork damaged by water. By addressing these issues before winter, you can prevent a minor maintenance task from becoming a major structural problem.

  • Modernise the Inventory and Condition Report

A simple and text-only inventory is not enough in the UK rental market. To protect your deposit and your rental property, you need clear and premium digital evidence. Between tenancies, hire a professional to create an inventory that includes detailed photographs and video walkthroughs of every room. This report should show the exact condition of carpets, walls, and fixtures.

Having an accurate record is the best way to resolve disputes at the end of a tenancy. It removes uncertainty and sets clear expectations for the next tenant. When a renter knows that every mark on the wall has been documented, they are more likely to take better care of the property.

Taking this step reduces your workload at the end of the next tenancy. It helps you spend your maintenance budget on improvements instead of fixing avoidable damage.

  • Re-evaluate the Market Position and Pricing

The UK rental market changes frequently. Simply relisting your property at the same rent may mean you miss out on additional income. Use any time your property is empty to compare it with nearby similar rentals. If you have made upgrades, like adding new appliances or improving security, you can charge a higher rent.

However, if your property stays vacant for too long, your rent might be too high for the current demand. Accepting a small rent reduction is often cheaper than dealing with a two-week vacancy. By evaluating your market position, you can find the proper rent that helps you earn more while reducing the risk of your property being vacant for a long time. Treat your rental price as a flexible number that reflects your property’s true value.
