Winter in the UK has a way of magnifying small property issues into major problems. A boiler that misses its autumn service might fail on the coldest night of January. A loose roof tile that shifts unnoticed in October can lead to weeks of damp spreading through insulation. A pipe that freezes in the loft can burst, sending water pouring into bedrooms below.
For landlords, these are not only expensive repairs but also stressful emergencies that disrupt tenants’ lives. At Mullucks, we know from experience that a proactive approach pays off. This winter property rental checklist will help you prepare effectively, reduce risks, and protect both your investment and your tenants.

Heating system & boiler checks before winter
Book an annual boiler service early
Every landlord must arrange an annual service and obtain a Gas Safety Certificate from a Gas Safe registered engineer. This is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998. Beyond compliance, a full service improves efficiency and identifies faults early. Booking in autumn avoids the December rush and reassures tenants that their heating is safe and reliable.
Check radiators and thermostats for efficiency
Radiators can collect trapped air, which prevents them from heating evenly, so bleeding them before winter helps the system run at full efficiency. At the same time, thermostats should be tested to make sure they are accurate and responsive since a faulty unit can waste energy and leave tenants uncomfortable.
Consider installing a smart thermostat
Smart thermostats allow tenants to control heating more effectively and, in some cases, can alert you if the boiler stops working. They are also increasingly popular with renters who value efficiency, and they help landlords demonstrate a commitment to reducing energy waste.
Preventing frozen pipes & plumbing problems
Lag exposed pipes to avoid freezing
Pipes in lofts, garages, and external walls are most at risk of freezing. Pipe lagging, which costs only a few pounds per metre, is a simple but effective preventative measure.
Show tenants where the stopcock is located
Many tenants have never been shown where the stopcock is or how to operate it. Demonstrating this can prevent a minor leak from becoming a flood.
Encourage background heating during cold spells
Ask tenants to keep heating on low, around 12 to 15°C, even when away. Frozen pipes are most common when properties are left unheated. Zurich reported that burst pipe claims rose by 75% during recent cold winters.
Roof, gutter & drainage inspection
Inspect the roof for missing or damaged tiles
A single missing tile can let in water, damaging insulation and timber. Arrange an inspection each autumn. Drone surveys are becoming a cost-effective way for landlords to spot roof issues safely.
Clear gutters and downpipes of autumn leaves
Blocked gutters often overflow and freeze into ice dams, forcing water back into walls. Clearing them before the first frost is one of the simplest ways to avoid damage.
Check if the ground drainage is functioning properly
Poor drainage can cause damp foundations or even flooding. Ensuring gullies and drains are clear reduces the risk of costly structural problems.
Damp, mould & condensation prevention
Provide effective ventilation in kitchens and bathrooms
Extractor fans should be tested to confirm they are working properly. Without adequate ventilation, steam from showers and cooking can quickly lead to mould.
Seal cracks where water could enter the property
Small cracks in render or gaps around windows allow water ingress. Sealing them before winter protects against damp.
Educate tenants about consistent heating and ventilation
Many mould problems arise from inconsistent heating and poor airflow. Written winter guidance helps tenants understand their role. Under the Homes Act 2018, landlords may be liable if damp and mould are caused by structural or ventilation issues.
Smoke, carbon monoxide & legal safety obligations
Install smoke alarms on every floor
Smoke alarms are legally required on every storey of a rental property. Test them before winter and replace faulty units.
Fit carbon monoxide detectors near fuel appliances
Detectors are required in any room with a solid-fuel appliance and are strongly recommended near gas boilers. Carbon monoxide poisoning is most common in winter when heating is in constant use.
Renew the annual gas safety certificate
Gas Safety Certificates must be renewed every 12 months by a Gas Safe registered engineer. This is both a legal duty and a reassurance for tenants.
Keep electrical condition reports up to date
An Electrical Installation Condition Report (EICR) is required at least every five years. With heating and electrical appliances running constantly in winter, checks are critical.
Sealing, insulation & energy efficiency measures
Seal draughts around doors and windows
Even small draughts can make a home feel cold. Draught-proofing strips and sealants are inexpensive but effective at reducing heat loss.
Top up loft insulation to the recommended levels
Poor loft insulation can waste up to 25% of a property’s heat. Insulation should be at least 270 mm deep to meet current standards.
Upgrade glazing where possible
Double glazing cuts condensation and reduces heat loss compared to single glazing. Properties with higher EPC ratings are more attractive to tenants and better positioned to meet future energy regulations.
Tenant responsibilities & communication for winter
Provide tenants with a winter guidance sheet
Clear instructions make it easier for tenants to care for the property. Guidance should include heating, ventilation, and what to do in case of leaks.
Share emergency contact numbers in advance
Tenants should know exactly who to contact in an emergency. Providing details before winter reduces stress when issues arise.
Encourage quick reporting of minor issues
A dripping tap or a small damp patch can quickly escalate. Encouraging tenants to report problems early helps landlords fix them before they become expensive repairs.

Q2. How often should landlords service boilers before winter?
Boilers must be serviced annually by law, ideally in autumn before demand peaks.
Q3. How can landlords prevent frozen pipes and leaks?
They should lag exposed pipes, encourage background heating, fix leaks promptly, and show tenants where the stopcock is located.
Q4. Who is responsible for damp and mould in a rental property?
Landlords are responsible if the cause is structural or ventilation-related. Tenants are expected to manage everyday condensation.
