How to Check and Resolve an Illegal Utility Connection

An illegal utility set up is not always obvious. It often goes unnoticed until something goes wrong such as a power outage, an accident or an inspection. Knowing what to look for and how to respond can protect people, property and your programme.

UK utility rules are strict. Unapproved connections can lead to fire, injury, legal action and costly delays. The right approach is simple: identify warning signs, report concerns and get a compliant supply installed by qualified professionals.

If you suspect an illegal connection do not touch it. Report it to the relevant provider or DNO and keep the area safe until it is assessed.

What an illegal utility connection really means

An illegal utility connection is any electricity, gas or water supply that has been connected without permission from the provider. This can include bypassing a metre, tapping into a nearby feed or running temporary lines that were never approved.

Even if the connection was created by a previous contractor, the current site management can still be held responsible. This is why clear oversight of temporary water and utilities and temporary power matters from day one.

Warning signs you should never ignore

Look for irregular metre readings, damaged cables, exposed wiring or supplies of unclear origin. Unexplained outages or equipment behaving unpredictably can also be a sign.

Sites using generators and temporary distribution can sometimes mix approved and unapproved feeds. Clear labelling, inspections and competent installation reduce the risk of confusion.

What to do if you suspect a problem

If you think something is wrong do not investigate by pulling panels, moving cables or testing connections. Interfering with utilities can make the situation worse and can put people at risk.

Report the issue to the relevant utility provider or distribution network operator. For suspected illegal electricity connections treat it as urgent due to the risk of fire and electric shock.

Resolving the connection the right way

Once confirmed the illegal connection should be removed and replaced with a certified supply. This typically involves permissions, proper metering and installation completed to current UK standards.

It is also wise to reduce the risk of tampering. Access control, fencing and temporary site security services such as temporary alarms and CCTV help protect utility points and equipment.
