React to most maintenance issues quickly and you’ll save on the repair bill. For example, an overflowing gutter can freeze, causing damage to your roof during the winter. Fix a loose fence panel during the autumn, before it becomes a costly replacement job after a storm. Fix things when the weather’s good, and you can almost always do a better, faster, cheaper repair than if the work is done during cold weather.
Winter: Protect Pipes, Prepare for Emergencies
The real-life cost of a burst pipe is quite tangible. Let’s take some data from the Association of British Insurers (ABI). Escape of water claims are regularly in the top three of the most common domestic insurance claims. The average cost of burst pipe damage following freezing weather is in the region of £9,300. That’s to repair it. It doesn’t include any loss of rental income while repairs are carried out. Nor the aggravation of a tenant unable to use a room in their home.
The prevention is pipe lagging. Exposed pipework in unheated areas, lofts, basements, under-floor voids, external cavities, is at risk in sustained cold weather. Foam lagging tubes are low-cost and simple to install. Do it before it’s too late. Every metre of exposed pipe in a cold zone should be covered.
Pay careful attention to the condensate pipe too. This white plastic pipe runs from a condensing boiler to an external drain and carries acidic water out of the system. Because part of it runs outside, it is highly prone to freezing in cold weather. When the condensate pipe freezes, the boiler shuts down altogether. Lagging this pipe or re-routing it internally where possible is one of the most effective winter prep steps a landlord can take.
Ensure every single tenant knows where the main stopcock is and how to use it. The stopcock, also known as the stop valve, is the switch that turns off all water entering the property. In the event of a burst pipe, turning it off within the first few minutes can halve the water damage suffered. Do not rely on a verbal explanation. Print a simple one-page guide with a photo or diagram showing the stopcock location and stick it inside a kitchen cupboard or utility room where it can be found under stress. Give this to every new tenancy as standard and re-share it with existing tenants at the start of each winter.
For landlords in London, it’s also time to find, or consolidate your relationship with, a contractor before you need one urgently. London landlords should already have a contractor’s number stored in their phone ready for emergencies. Using PM247 London Plumbing Services for urgent boiler breakdowns or frozen pipe emergencies means you’re not part of the annual surge of demand seeking urgent assistance, when every local plumber is overrun and they can’t get to you for days.
Spring: Assess the Damage Winter Left Behind
Winter can cause silent damage. When the temperature rises again, your property may already suffer from hairline cracks in outdoor brickwork, weakened pointing, or small pipework fractures outside the property due to freezing temperatures, expanding but going unnoticed. Spring is your opportunity to catch these issues before the rains arrive.
Take a general walkthrough outside. Run your eye along every run of guttering and downpipe to look for blockages, sagging, or joint separation. A blocked gutter is not just an aesthetics problem, water trapped and unable to drain saturates the fascia board and eventually infiltrates the wall cavity. That’s damp. Damp is costly, time-consuming, and a potential source of tenant disputes.
Check outdoor taps for cracking or internal fracturing. Water trapped inside an unprotected outdoor tap during a frost can cause the fitting to crack internally, and sometimes you won’t see the external damage until you turn on the tap under pressure. Turn them on and check the flow and the wall plate. If it’s not flush and water-tight, replace.
Likewise, this is an opportunity to run your indoor plumbing fixtures. Look under the kitchen and bathroom sinks for any slow weeps or discolouration on the cabinet floor, suggesting a joint that moved over the winter. A steady little drip left unattended for weeks gives the mould conditions behind the cabinetry time to flourish, and that’s a more expensive repair than the original leak.
Summer: Use the Quiet Months Strategically
Many landlords overlook summer as a maintenance season. But they shouldn’t. This is the one window in the year when your tenants aren’t relying on the central heating system, and therefore the one time you can fix or upgrade central heating and its associated plumbing without inconveniencing anyone.
If your boiler is over a decade old, get it assessed now. Don’t wait for it to fail in the first cold snap. A boiler replacement undertaken in summer conditions, when you can shop around and select a date for the installation rather than pay for an emergency call, could save you a lot.
The same goes for radiator panels or whole radiators; cylinder replacements; pipework rerouting; or virtually any other heat-producing kit. If it means a system shutdown, do it now or in the next few months before the first serious cold weather.
Is your central heating plumber recommending a power flush because the system has been running for many years since its last flush? Sludge, which is part corroded metal from the system and part scale from the hard water in the system, gathers in the pipework and radiator panels and gradually reduces the system’s efficiency so that the pump on your boiler has to work harder. A power flush of the system would solve that. It’s not cheap, but it is a lot less inconvenient in a summer fortnight without heating than when it’s urgently needed in November and all the good gas engineers are booked up for two weeks.
This is also the time to give your extractor fans in kitchens and bathrooms a bit of a test. They don’t get used in warm weather, obviously enough, but they are vitally important in winter, when windows are mostly kept shut and the behaviour of cooking and bathing releases a lot of moisture. A fan that either moves slowly or doesn’t run moves no moisture at all and will contribute directly to your condensation and mould problems in winter. (Mould is your problem as a landlord, not their problem as a tenant.)
Autumn: Commission the Heating System Before the Cold Snap Hits
October can be a real pressure point. This is often the first time that the heating goes on, and whatever the system’s been hiding over the summer exposes itself, usually at 9pm when you’re not in the office.
Before the end of September, get in touch with your tenants and talk them through the heating commissioning process. The key tasks couldn’t be simpler: bleed the radiators to let out any air that’s been building up over the off-period, and check the boiler pressure. 1.0-1.5 bar is a healthy pressure reading. Anything lower than 1.0, and the system will need topping up via the filling loop. It’s a five-minute job with minor instructions, which your tenant could carry out or you can do as part of a routine inspection.
Check that all your Thermostatic Radiator Valves are moving freely. October sees more callouts for poor radiator performance than any other month, and TRVs are often the culprit. If the TRV is stuck closed, the radiator won’t heat, which will generate a complaint, which will distract you from identifying a much bigger circulation problem. Turn them all the way up and down by hand. If they feel stiff when closing, they should be replaced before winter.
Check the carbon monoxide detectors are in good working order, required by law in solid fuel properties in many regions, but they should also be in place in any gas boiler property. Test them, replace the batteries and check their position in the autumn.
It’s also time to do Legionella risk assessment review, particularly if your property has been void over the summer months. Any property left unoccupied for more than a week should have all of its taps, showers, and outlets run for a minimum of two minutes before a new tenancy. Stagnant warm water is exactly the breeding ground the Legionella bacteria love, and your legal responsibility for managing that risk as a landlord is crystal clear.
Year-Round Compliance That Doesn’t Slip Between Seasons
There are two things that you just can’t save up for when landlord life eventually gets busy: emergency contractor access, and gas safety checks.
The Landlord Gas Safety Record (the CP12) must be renewed annually by a registered gas engineer. Not renewing it isn’t just a compliance risk; it’s criminal liability in most areas. Lock it into your calendar as a fixed annual date and don’t push it over its renewal date courtesy of a tenancy switch or an administrative backlog.
Emergency contractor access is needed and current all year long. Seasonal cold snaps don’t give notice. A pipe that freezes in an unheated property while tenants are away for the holidays can burst and run for days before anyone notices. Knowing your emergency contact is already vetted, already knows the property type, and can respond at 2 am on a bank holiday is the difference between a managed incident and a significant loss.
Keep a simple property file for each unit, boiler make and model, service dates, stopcock location, contractor contacts, and the date of the last safety check. It takes an hour to set up and saves considerably more time than that the first time something goes wrong at short notice.
Seasonal maintenance isn’t a burden if it’s structured. It’s a rhythm. Work through each transition, spring inspection, summer upgrades, autumn commissioning, winter protection, and the system holds. Let it drift, and the problems don’t disappear. They just accumulate until something fails at the worst possible time.
