How do I know if it's my house or a TNB outage?

Check if neighbouring units or houses also have no power. If they still have power and only your unit is dark, it is almost certainly an internal fault needing an electrician rather than a utility fault.

Is total power loss dangerous?

It can be, especially if it is caused by an arcing connection or a burnt consumer unit. Avoid touching the main switch or panel if you smell burning and call an electrician straight away.

Can this be fixed at night?

Many electricians on 24-hour callout lists do handle night visits for total power loss since it is treated as a genuine emergency, unlike a single dead socket.

No power at home? Urgent electrician callout

Total loss of power, where the whole house or unit goes dark and the main breaker or meter itself seems to be the problem, needs a different response from a single tripping circuit. This page covers the specific situation of no power at all, which can point to a main breaker failure, a burnt meter connection, a TNB supply issue, or a serious fault at the consumer unit.

An electrician responding to this will first check whether the outage is isolated to the property or affecting the neighbours, since that changes whether the fix is inside the house or a utility matter. If it is internal, they will inspect the main switch, the meter tails and the consumer unit for burning, arcing or a tripped main breaker that will not reset.

Have your meter number and any burning smell or sparking details ready when you call
Do not repeatedly try to switch the main breaker back on if it trips instantly, that usually signals a serious fault
If the consumer unit shows scorch marks, mention this immediately as it changes the urgency

What it costs

Cost is driven mainly by the time of the callout (after-hours and public holiday visits typically cost more) and whether the fix is a straightforward breaker reset versus replacing burnt meter tails or a damaged consumer unit, which involves parts as well as labour.
