No Power and Cables Stolen? Emergency Steps for Factory and Warehouse Owners
It is 6 AM on a Monday. You open up the unit and nothing works. No lights, no shutters, no compressors. You find the intake cupboard door forced, the distribution board hanging open, and bare copper tails cut clean where heavy cable used to run. Somewhere over the weekend, someone stripped the electrical infrastructure out of your building for scrap.
Your first instinct is to walk in and look at the damage. Do not do that yet. Read the next two minutes of this page first, because the single most dangerous moment after a cable theft is the hour after it is discovered — when the person who owns the building goes in to see how bad it is.
Quick answer: Do not enter the affected area or touch any cable. Cut conductors can remain live even when the building appears dead. Get everyone out and hold them at a safe distance, call 105 (free, 24/7) to report it to Electricity North West so the supply can be made safe, then call 999 if anyone is in danger or 101 to report the crime and get a crime reference number. Only once the supply is confirmed isolated should a qualified electrical contractor survey the damage.

Is It Safe to Go In After Cable Theft?
No — not until the supply has been confirmed isolated by the network operator or a competent person.
This is the part that gets people hurt. Business owners assume that because the lights are off, the building is dead. That is frequently wrong, for three reasons:
- The intake is usually still live. Thieves take the cable that is easy to reach and worth the most — typically the sub-mains, distribution tails and armoured runs downstream of the intake. The service head, the cut-out and the meter tails are often untouched and still connected to the network. There can be full supply voltage sitting a metre from where the cable was cut.
- Cut ends are unterminated and unprotected. A stripped cable end has no gland, no shroud and no enclosure. It is bare copper at potentially 400 V three-phase, lying on a floor that may be wet.
- Partial theft leaves live sections. Thieves rarely strip a building completely. They take the accessible runs and leave the rest energised. Half a building being dead tells you nothing about the other half.
Treat every cable, every board and every piece of exposed metalwork as live until an electrician tells you otherwise.
The First Hour: What to Do in Order
1. Get people out and keep them out
Stop anyone else entering. Staff arriving for shift should be held in the car park or sent to wait off site. Put someone on the door. If the theft is in a yard or external area, cordon it off — cones, tape, a vehicle parked across the access, anything that stops someone wandering in.
If anyone has already touched cable or is showing signs of electric shock, call 999 immediately.
2. Call 105 to report the supply as unsafe
105 is the free national power cut number. It routes automatically to your local network operator — in Greater Manchester that is Electricity North West. It is staffed 24 hours a day, 365 days a year.
Tell them explicitly: "We have had cable stolen from our commercial premises. There are exposed cut conductors and I need the supply made safe." Those words matter. This is not a routine power cut report — it is a danger report, and it is prioritised accordingly.
Electricity North West can also be reached directly on 0800 195 4141.
The network operator will attend and make the incoming supply safe. They are responsible up to and including the cut-out and meter. Everything downstream of that — your distribution boards, sub-mains, final circuits — is your responsibility and needs a private contractor.
3. Report the crime and get a crime reference number
Call 101 to report the theft (or 999 if the offenders may still be on site). Insist on a crime reference number before you end the call.
You will not be able to progress an insurance claim without it. Insurers routinely refuse to open a claim file on a theft without a police reference, and chasing one retrospectively days later is far harder than getting it on the first call.
4. Photograph everything before anything is touched
Once you can do so from a safe distance, photograph:
- Every point of forced entry — doors, shutters, fences, roof lights, ceiling voids
- Every cut cable end, wide shot and close up
- Empty cable tray, trunking, conduit and ladder rack where cable used to run
- Open or damaged distribution boards, isolators and switchgear
- Damage to the fabric of the building — pulled ceilings, lifted floor plates, damaged walls where cable was dragged out
- Any tools, cable off-cuts, insulation stripping or vehicle tracks left behind
- Wide establishing shots of each affected area so the scale is clear
Photograph with a phone that timestamps the images. If your CCTV survived, export and back up the footage immediately, before it loops and overwrites itself. Many systems only retain seven days.
5. Call your electrical contractor
Once the supply is being made safe, get a commercial electrical contractor mobilised. What you need from them in the first visit is not a full repair — it is:
- Confirmation of what is dead and what is still live
- Safe isolation and temporary protection of exposed conductors
- An assessment of the extent of the theft and damage
- A route to temporary power if any part of the business can run on it
- A written report you can hand to your insurer
6. Notify your insurer
Call your insurer or broker as soon as the immediate danger is controlled. Most commercial policies require notification "as soon as reasonably practicable" and some specify a window as short as 48 hours for theft claims.
Have ready: the crime reference number, the approximate time window of the theft, a description of what has been taken, and confirmation that the site has been made safe.
What Not to Do
| Do not | Why | |---|---| | Touch or move any cut cable | Conductors may be live at 230 V or 400 V | | Switch anything back on to "test" it | Energising a damaged installation can cause fire, arc flash or fatal shock | | Clean up or clear debris | Destroys evidence for police and insurers | | Reset or re-close tripped devices | Protective devices may have operated for good reason; earthing may be compromised | | Let staff work "around" the affected area | Damaged earthing can make metalwork live anywhere in the building | | Wait until morning to report it | Delayed notification weakens both police response and insurance position | | Use a general handyman or non-registered electrician | Insurers and Building Control need certified work from a registered contractor |
Can You Get Any Power Back the Same Day?
Often, yes — partially.
Full replacement of stolen sub-mains and distribution can take days or weeks depending on cable lead times. But most businesses do not need everything back at once. They need the parts that stop them trading to work again.
A competent contractor will usually approach it in stages:
Stage 1 — Make safe (hours). Isolate, terminate or shroud exposed conductors, verify earthing integrity, establish which parts of the installation are intact and safe to energise.
Stage 2 — Temporary supply (same day to 48 hours). Where the intake is intact, a temporary distribution arrangement can often be built to feed the critical loads — server room, alarm and fire systems, cold storage, one production line, essential lighting. This can involve temporary distribution boards, temporary armoured runs on the surface, or generator connection where the intake itself has been destroyed.
Stage 3 — Permanent reinstatement (days to weeks). New cable installed on the correct routes, new containment where trays and trunking were destroyed, boards replaced, full inspection and testing, certification issued.
The priority order should be driven by your business, not by the electrician. Be ready to say clearly: "If I can only have three things back today, I need the cold store, the alarm and the goods-in shutter."
What About Fire Alarms, Emergency Lighting and Security?
This is the part that catches people out. Cable theft almost always takes out life-safety systems, because the cabling for those systems runs on the same trays and through the same voids as everything else.
If your fire alarm, emergency lighting or sprinkler monitoring is dead:
- You may not be legally able to occupy the building. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must maintain fire safety measures in efficient working order. A dead fire alarm system in an occupied commercial building is a serious matter.
- You will likely need a fire watch. If you must occupy the premises before the alarm is restored, a documented temporary measure — usually a manned fire watch with a clear evacuation procedure and temporary call points — is normally required. Speak to your fire risk assessor.
- Your insurer needs to know. Most commercial policies carry conditions requiring functioning fire detection and intruder alarm systems. Operating without them, unnotified, can prejudice cover on any subsequent claim — including a fire.
Why Factories and Warehouses Are Targeted
Understanding the pattern helps you protect the site afterwards.
Metal theft costs the UK economy an estimated £500 million a year, and there are more than 15,000 recorded metal theft cases annually. The Association of British Insurers has put member payouts at over £1 million per week.
The driver is the copper price. Through 2026, copper has traded at historic highs — LME cash settlement in the region of $13,000 per tonne — and scrap values have followed. Bare bright copper wire currently fetches roughly £6,500 to £7,500 per tonne, with insulated cable at around £2,500 to £3,500 per tonne. Every time the copper price climbs, cable theft climbs with it.
Industrial premises are attractive because:
- The cable is heavy. Factories and warehouses have high power demands, which means large sub-mains and armoured cable — far more copper per metre than a shop or office.
- They are quiet at predictable times. Friday evening to Monday morning is a 60-hour window. Bank holidays give 84 hours. Christmas shutdown can give two weeks.
- They are often isolated. Industrial estates with no residential overlook, shared yards, and neighbouring units that are also empty at weekends.
- Partial occupancy is common. A building with a vacant floor, a mothballed production hall or an unlet unit gives thieves a working area where nobody will notice noise or lights.
Frequently Asked Questions
I came in this morning and there is no power — how do I know if it is a theft or a power cut?
Call 105 first either way; they will tell you whether there is a recorded fault or outage on the network in your area. Signs pointing to theft rather than a supply fault include forced entry to the intake cupboard, riser or plant room, cable ends cut cleanly with visible bare copper, empty cable tray or trunking that clearly used to carry cable, and insulation stripping or off-cuts left on the floor. If the network reports no fault and your neighbours have power, treat it as a theft and a danger.
Can stolen cable still be live?
Yes. This is the single most dangerous misconception after a cable theft. Thieves typically take accessible sub-mains and leave the incoming supply connected, so cut ends downstream of a live source can sit at 230 V or 400 V with no enclosure and no protection. Never touch, move or test a cut cable. Wait for the network operator or a qualified electrician to confirm isolation.
Who is responsible for the repair — the network operator or me?
Electricity North West is responsible up to and including the service cut-out and meter. Everything on your side of that point — sub-mains, distribution boards, final circuits, containment, earthing and bonding — is the building owner's or occupier's responsibility and must be repaired by a private electrical contractor. The network operator will make the supply safe but will not reinstate your internal installation.
How quickly can power be restored after cable theft?
Making the site safe usually takes hours. A temporary supply to critical loads can often be established the same day or within 48 hours where the intake survives. Full permanent reinstatement typically takes several days to a few weeks, driven mainly by cable lead times, the length of the runs, and whether containment and switchgear also need replacing. Staged restoration means most businesses are partially trading long before the permanent work is finished.
Do I need a crime reference number for my insurance claim?
Yes, in practice always. Insurers will not normally progress a theft claim without a police crime reference number, and obtaining one retrospectively is significantly harder. Get it on your first call to 101 and record it somewhere safe alongside the date and time of the report.
Should I clean up before the loss adjuster visits?
No. Leave the scene exactly as found, other than any action necessary to make people safe. Cable off-cuts, discarded tools, damaged containment and the pattern of what was taken all evidence the scale and nature of the loss. Photograph everything, then leave it. Premature clearance is one of the most common reasons claims are disputed or reduced.
Will my business interruption cover pay for the downtime?
It depends on your policy wording. Many commercial combined policies include business interruption cover that responds to damage caused by an insured peril, and theft with damage is normally an insured peril. However, cover is typically subject to the property damage claim being accepted, so any unoccupancy or minimum security breach that defeats the property claim will usually defeat the BI claim with it. Our insurance guide covers this in detail.
