General and out of hours emergency maintenance

This relates to any maintenance issue where by the property could be made to be unsafe or considerable damage may be caused to the property as a result of delay in action – Appliances do not fall under an emergency and you should report this to your Property Manager during business hours.

Any instances of Anti-social behavior (resulting in concerns for safety) or burglary must be reported to the police immediately – A crime reference number will be required for any subsequent insurance claim (in case of burglary).

Please be aware there are some instances where you will be required to notify the relevant authorities as follows:


Gas Leak: If you smell gas you should immediately turn off the gas supply to the property if the meter is accessible. You must contact Transco as soon as possible to report the leak and exit the property until you are advised the issue has been resolved. You should inform the Property Manager of any works carried out or remedial works required the next working day for follow up.

Carbon Monoxide:

If your Carbon Monoxide Alarm goes off you should immediately open the windows in the property to let in fresh air. Exit the property and call Transco to report the issue. If you are experiencing any health issue as a result you should contact either your doctor or the emergency services. Please ensure you notify the Property Manager the next working day.


Loss of Supply: Please initially check the fuse box for the property and ensure that no fuses have been tripped – If the fuse have tripped please try to return them to the “ON” position. Please also check with your neighbours to ensure they are not also experiencing the same issue as this would indicate loss of power to a larger area. Providing the answer to these questions is negative you should contact National Grid Emergency 0800 111 999 to report the fault. You should update your property manager the next working day.


Supply issue: Before contacting Black Katz Emergency line you should first check with Thames Water to ensure there are no scheduled works being carried out to the supply in your area and your neighbours to ensure they are not experiencing the same issue (which would indicate works being carried out). In times of low temperatures during winter months please ensure that your pipes are not frozen as this can also affect the supply.


Immediately shut off water supply using stop cock and immediately advise the emergency line of the issue. You should take steps to reduce the water flow through the property as best as possible using receptacles or towels to catch the leaking water until an engineer attends.
