As the days grow shorter and temperatures begin to drop, winter brings a host of challenges for properties across the UK. From frozen pipes to faulty boilers, minor maintenance issues can quickly become major problems once the cold sets in. For landlords and letting agents, preparing properties before winter takes hold is not only a matter of comfort for tenants, but also a way to protect long-term investments and avoid costly emergency repairs.

This guide outlines key maintenance checks and practical steps to ensure your properties are winter-ready, safe, and compliant.

Inspecting Heating Systems

A functioning heating system is the cornerstone of a well-maintained winter property. Tenants rely on heating not just for comfort, but for health and safety. Before the temperature drops too far, landlords should arrange for boilers and central heating systems to be serviced by a Gas Safe registered engineer. Annual servicing ensures efficiency and can identify problems such as low pressure, leaks, or faulty thermostats before they cause a breakdown in mid-December.

Radiators should also be checked for cold spots and bled if necessary. In properties with older systems, consider fitting thermostatic radiator valves to improve temperature control and energy efficiency. It’s also wise to test any electric storage heaters or panel heaters ahead of time.

Landlords are legally required to provide adequate heating, and a proactive approach will help avoid tenant complaints and emergency call-outs when engineers are in short supply during peak season.

Preventing Frozen and Burst Pipes

Few issues cause more disruption in winter than frozen pipes. The resulting leaks and water damage can be both expensive and stressful to put right. Pipes that run through unheated spaces such as lofts, basements, garages, and external walls are especially vulnerable.

Insulating these pipes with foam lagging is a straightforward and affordable way to reduce risk. For empty or void properties, it is sensible to leave the heating on low or set the thermostat to a minimum temperature to prevent freezing. Smart heating controls can be particularly useful here, allowing remote management of temperatures without visiting the property in person.

It is also worth reminding tenants to keep the heating on a low setting if they are away during cold spells. Providing clear guidance on what to do if a pipe freezes, including where the stopcock is located, can make a significant difference in limiting damage.

Roofs, Gutters and Drains

Autumn leaves and debris can quickly clog gutters, leading to overflowing water and damp problems inside walls and ceilings. Before winter, gutters and downpipes should be cleared of leaves, moss, and twigs, and any cracks or loose joints repaired. Check that all drains and gulleys around the property are free-flowing, as heavy rain and snowmelt can otherwise cause pooling and damage to external brickwork or foundations.

Roof inspections are equally important. Broken, slipped, or missing tiles can allow water ingress, which may not be obvious until it becomes a larger problem. A professional roofer can assess the condition of tiles, flashing, and ridge lines. Flat roofs in particular should be checked for signs of pooling water or splits in the membrane.

Damp and Ventilation

Winter is the season when condensation and damp are most likely to appear. Poor ventilation, combined with tenants keeping windows closed and drying clothes indoors, can lead to black mould growth. Landlords should make sure extractor fans in kitchens and bathrooms are working properly and, if fitted with timers, that they run for long enough to clear moisture.

Providing tenants with dehumidifiers or reminding them to use trickle vents can help reduce condensation. If the property has a known history of damp, consider fitting humidity sensors or positive input ventilation (PIV) units, which improve air quality and prevent mould build-up.

Not only does addressing damp protect the property fabric, it also reduces the risk of disputes or health complaints related to mould exposure. For further information, check out our dedicated blog on damp and mould compliance.

Electrical Safety and Lighting

With more hours of darkness, good lighting becomes essential for both safety and security. External lighting should be tested and fitted with energy-efficient bulbs. Motion sensor lights are a useful deterrent for intruders and provide reassurance for tenants arriving home after dark.

Inside the property, it is a good time to check that smoke and carbon monoxide alarms are in working order. Landlords are legally obliged to ensure alarms are installed and tested at the start of each tenancy, but seasonal checks add an extra layer of protection. Replacing batteries and checking expiration dates can prevent avoidable incidents.

If the property has not had an Electrical Installation Condition Report (EICR) in the past five years, arranging one now will ensure continued compliance with legal requirements.

Windows, Doors and Insulation

Poor insulation can lead to higher energy bills and discomfort for tenants. Before the coldest months arrive, inspect windows and doors for draughts and gaps. Simple measures such as fitting draught excluders, sealing gaps with weatherstripping, and adding thermal curtains can significantly improve warmth and reduce heating costs.

If the property is older, check loft insulation and top it up if necessary. Around 270 mm of insulation is recommended to meet current energy efficiency standards. Walls can also be a major source of heat loss, so cavity wall insulation may be worth considering if it has not already been installed.

Good insulation benefits both tenants and landlords by improving Energy Performance Certificate (EPC) ratings and increasing property value. There are proposed changes to the EPC requirements, and familiarising yourself with these sooner rather than later can help to keep you ahead of the curve when it comes to planning proactive maintenance across your property portfolio.

Garden and Outdoor Areas

External maintenance is often overlooked during winter preparation, yet outdoor areas can pose risks if left unattended. Overgrown trees or branches should be trimmed back, particularly those close to roofs, windows, or power lines. Garden furniture should be secured or stored away to prevent damage in high winds.

Paths, driveways, and steps should be inspected for cracks or uneven surfaces that could become hazardous when icy. Having a supply of salt or grit available for tenants to use during frosty periods is a thoughtful touch that also helps prevent accidents.

External taps should be isolated and drained to prevent freezing. If a property has an irrigation system, it should also be turned off and drained for the season.

Managing Tenant Communication

Maintenance is far more effective when tenants are informed and involved. Letting agents and landlords should communicate clearly about any scheduled maintenance visits and remind tenants how to report issues quickly. Providing a winter checklist or guidance sheet can help tenants understand their role in keeping the property safe and warm.

This communication should include emergency contact numbers, instructions for boiler resets, advice on avoiding condensation, and reminders about safety checks. A well-informed tenant is far more likely to act promptly if a problem arises, reducing damage and costs.

Planning Ahead for Emergencies

Despite the best preparation, emergencies can still occur. Having a clear plan in place helps minimise disruption. Keep a list of reliable contractors for heating, plumbing, roofing, and electrical work, and confirm their availability during the winter months. Letting agents managing multiple properties may benefit from setting up maintenance contracts or service level agreements to ensure a rapid response when issues arise.

Landlords should also review their insurance policies to ensure they cover damage from winter-related incidents such as burst pipes or storm damage.

A Season for Proactive Management

Winter maintenance is not just about avoiding inconvenience; it is about protecting assets, fulfilling legal responsibilities, and maintaining tenant satisfaction. The cost of a few proactive inspections and minor repairs is far lower than the expense of emergency call-outs or long-term property damage.

By taking a thorough and organised approach to winter maintenance, letting agents and landlords can safeguard their properties, keep tenants comfortable, and reduce the likelihood of seasonal disruptions. The result is a warmer, safer, and more efficient home for everyone involved. Book your 20 minute, no-commitment demo today and see how much time and money togetha can save your business.
