What to Do if Your Home Suddenly Loses Electricity in Hemel Hempstead

A sudden loss of electricity is one of the most common reasons for an emergency call-out, and it can be caused by anything from a wider supply issue to a fault within your own home's wiring. Knowing a few simple checks can help you work out which it is before deciding what to do next.

If your Hemel Hempstead home has completely lost power, the first thing to establish is whether it's just your property affected, or a wider issue with the electricity supply to your street.

Checking the cause

Look out of the window to see if neighbouring houses and street lighting are affected. If they are, it's likely a supply issue rather than a fault in your home, and you should contact your electricity network operator - in this area, that's typically UK Power Networks - rather than an electrician. Power cuts affecting a wider area are usually resolved without any work needed on your own installation.

If only your property has lost power, check your consumer unit for a tripped main switch or individual circuit breaker. If it resets and stays on, the issue may have been a temporary overload. If it won't reset, or trips again immediately, this indicates a fault that needs an electrician rather than repeated attempts to switch it back on.

When to call an emergency electrician

Partial loss of power - where some rooms or circuits have electricity and others don't - almost always points to a fault within the home rather than a supply problem, and is worth getting looked at promptly, particularly if it affects things like the fridge-freezer or heating system controls.

JH Electrical 247 Ltd offers emergency electrician cover across Hemel Hempstead for sudden loss of power and related electrical faults. If you've ruled out a wider supply issue and your home still has no electricity, or the consumer unit won't stay reset, it's best to get a qualified electrician out to identify and fix the fault safely.
