Up to 1,400 people in Seven Kings were left without a landline phone connection after lightning damaged two cables last Thursday.
Although a temporary repair was made yesterday restoring the majority of connections, reports have been received that the problem persists in some properties in Elgin Road.
The lightning struck two underground cables in Meads Lane, Seven Kings.
BT said an estimated 17 people still have no connection but this should be resolved tomorrow.
A BT spokesman said: “BT would like to apologise to customers affected by the break in service caused by damage to two underground cables in the Meads Lane area.
“Engineers have been working hard to restore service.”
If your phone service is still not working BT advise you to contact your service provider.
