How to avoid burst pipes in your rental property
The cost of burst pipes
Hamilton Fraser’s Total Landlord Insurance has seen a steady decline in the number of insurance claims over the past few years, this could signal a number of things including landlords being better educated about the importance of taking care of property maintenance and forming good relationships with their tenants.
Despite a reduction in the number of claims year on year the cost of claims related to escape of water have consistently risen, with one major contributing factor being increasing labour and material costs, making repairs more expensive. Despite landlords best efforts to protect their property sometimes claims are inevitable due to factors outside of their control.
34 per cent of claims paid out since 2008 have been for ‘escape of water’, defined as ‘when water has entered the property by the mains water supply and caused damage’ e.g. a burst pipe. This is two and a half times more than the next most common reason.
And of these claims, more than three quarters have been down to a burst pipe – that’s a hefty quarter of all claims received by Total Landlord Insurance in the last ten years. What’s more, over the past three years claims arising from a burst pipe have been increasing steadily while other claims involving water have declined sharply.
The consequences of burst pipes
The consequences of burst pipes can be devastating. A burst pipe in the main system can affect neighbouring properties, leaving a significant number of people without water and even homes. A more contained leak can still be a headache for your tenants and a hassle for you as the landlord, causing emotional, financial and physical stress to all concerned. Possible consequences of burst pipes include:
- Structural and cosmetic damage to your rental property and potentially neighbouring properties too
- Damage to furniture, fixtures, fittings and appliances in the rental property and potentially neighbouring properties affected
- Expense and hassle of repair/restoration work and relocation of tenants
- Stress and inconvenience for landlord, tenants and neighbours
- Loss of rental income due to a vacant property while repairs are carried out
Even a small pipe fracture can release huge volumes of water if left unchecked, resulting in heavy insurance claims and sometimes £100,000+ repair bills for water damage to buildings, contents and drying out.
What causes burst pipes?
During the winter months, water coming into the property from outside is much colder than it is during the rest of the year. The colder water can cause a contraction in the pipes, which sometimes leads to leaks where the pipe has weakened over time. This is why escape of water claims increase during the winter months, when pipes freeze and begin to leak or burst.
The most common causes of burst pipes are:
- Water freezing in pipes during cold weather
- Increased water pressure
- Wear and tear
- Ageing pipes
Controlling the temperature of water coming into the property is clearly not a practical option. But there are a number of steps you can take, such as preparing your pipes for cold weather and carrying out routine maintenance on your pipes, all of which will help lower your risk.
Prevention is definitely better than cure when it comes to burst pipes. Be sure to share these tips with your tenants.

Practical tips to prevent pipes from bursting:
- Ask tenants to keep heating on low (around 13°C) if they go away– this will prevent temperatures from dropping below freezing in any areas of the property where water pipes are located
- Keep one or two taps running slowly for several hours a day– if it is extremely cold outside water moving through the system should prevent freezing and a build-up of pressure
- Allow warm air to circulate– pipes are more likely to freeze if located near an outside wall or a window, so direct warm air to any colder areas of the property. It is also a good idea to leave cupboard doors under the kitchen sink and bathroom cabinets open so that warm air can circulate around pipes that are exposed to the cold
- Use heat tape– there is a product called heat tape that can be installed and will warm pipes as needed during cold weather. Contact a plumber for more information
- Seal leaks– identify and seal any air leaks that allow cold air into your property where pipes are located, for example around electrical wiring, dryer vents, and pipes
- Isolate the water supply to any outside taps with an internal shut-off valve– outside taps and associated pipework are always a problem in freezing weather
- Replace the washers on dripping taps– if they freeze the pipes will block
- Lag pipes and insulate– this will provide extra protection against frost. Pipes in unheated areas, including lofts and basements or those fixed to the inside of external walls are most at risk from freezing. Pipes should be lagged using insulating foam sleeving – the thinner the pipe the thicker the insulation should be
- Insulate old water storage tanks– although all new water storage tanks must be insulated, older ones will benefit from a hot water jacket. Take care not to place loft insulation directly under heater tanks though, as this stops heat rising from below
- Service your boiler and central heating system annually before winter– to prevent breakdowns during cold spells when it is working its hardest
- Carry out routine maintenance on your water pump and bathroom fixtures – to prevent burst pipes due to water pressure. Carry out regular inspections of the pipes and associated plumbing so that you can identify problems early. Encourage your tenants to contact you immediately if they spot any issues, for example a blocked toilet

What extra precautions should you take if your rental property is unoccupied for long periods?
Landlords with holiday homes or rental properties that may be vacant for long periods have a responsibility to prevent burst pipes and avoidable insurance claims and need to take extra precautions.
1. Leave the heating on – this may cost a little more in bills but will help protect your property from the expense of repairing damage should pipes burst. It is recommended to leave the heating permanently on at least 13 degrees, especially during very cold periods, rather than for short bursts at a higher temperature.
2. Turn off the stop cock – this is essential during frost or if you have certain types of heating systems such as storage heaters, which do not provide the continuous levels of heat that are required to prevent pipes from freezing.
3. Drain down the heating/water system – if your property will be vacant over winter and cold weather is expected, the safest thing to do is to drain down
and shut off the water/ central heating system so that there is nothing in the pipes to freeze. It is not enough to simply turn off the water as there will still be water in the system and tanks, which can cause damage in the event of a burst pipe. Seek the advice of a plumber or heating engineer on how to drain down the water and central heating system.
4. Allow warm air to circulate – during freezing temperatures leave the loft hatch door open to allow the warmer air from your holiday home to circulate up and around the water tank and water pipes.
5. Ask someone to check on your property – during a particularly cold it is useful if you can arrange for a neighbour or housekeeper to check your property regularly. This will increase the chances of detecting frozen or burst pipes early and minimise damage.
What should you do if faced with a burst pipe?
Knowing what to do if the worst happens can help reduce both the spread of water damage and the size of your claim. Follow these steps:
1. Close off the water supply – turn off the water mains at the stopcock (often found under the kitchen sink)
2. Turn off the electricity – if there is a risk of water reaching electrical equipment, turn off electricity at the fuse box. Keep away from light switches and sockets
3. Move any furniture and belongings away from the affected area – your insurance will not cover your tenant’s possessions
4. Survey for damage– check the property for water damage, for example a bulging ceiling which could indicate that water is pooling above
5. Contain excess water – collect the water into large containers and mop up any excess water to help prevent secondary damage
6. Use a dehumidifier– provide your tenants with a dehumidifier as this will help remove any water or dampness from the property (which will also help prevent condensation, damp and mould).
If the moisture is contained within a specific room, close the windows and doors as dehumidifiers work best in enclosed areas
7. Contact an emergency plumber – if the pipe is concealed a plumber may be needed to locate and repair the leak
8. Collect evidence – if making a claim take lots of photos of the damage
9. Ensure that guests or tenants have an action plan – in case of an emergency make sure you provide your tenants with information on how to turn off the water and who to contact (agent, housekeeper, plumber)
