Energy theft — tampering with gas or electricity meters to avoid paying — is a criminal offence in the UK. It carries penalties including unlimited fines and up to five years imprisonment (GOV.UK, 2026). The practice also creates serious safety hazards, including fire, explosion, and electrocution risks for your household and neighbours.

As a homeowner, you are responsible for the safety of your property’s electrical and gas installations, even if you did not commit the theft yourself. The most important first step is knowing how to spot the signs of tampering and what to do if you suspect it.
How to spot the physical signs of a tampered meter
Physical indicators of meter tampering are often visible if you know what to look for. Check your meter for damage, loose wires, bypass cables that connect the meter’s input directly to the output, or broken or missing seals (Energy Networks Association, 2026).
Look for unusual smells (gas odour) or scorch marks around the meter or fuse box. Inspect the meter cabinet for signs of forced entry, such as bent or broken locks. If you have a smart meter, check the display for unexplained error codes or readings that do not match your usage history (Ofgem, 2026).
How to identify suspicious behaviour from a previous owner or tenant
If you have recently moved into a property, request a meter reading from the supplier and compare it with the meter’s serial number and seal condition. Ask the supplier for a meter inspection if you notice any discrepancy between the reading and the property’s expected energy use (Citizens Advice, 2026).
Check the meter box for signs of recent tampering, such as fresh tool marks or displaced insulation. If you are unsure, contact your energy supplier or the police non-emergency number (101) for guidance (Ofgem, 2026).

| 5 | Typical cost to replace a tampered electricity meter | £200–£500 (supplier-dependent, Ofgem) |
Who is eligible to report energy theft, and how to do it safely
Any homeowner or resident can report suspected energy theft, regardless of whether they own or rent the property. You do not need proof — a reasonable suspicion is enough to trigger an investigation by your supplier or the police (Energy Networks Association, 2026).
The safest way to report is via the Energy Theft Hotline (0800 023 2777) or through your energy supplier’s fraud team. Never attempt to inspect or repair a tampered meter yourself — call a qualified gas-safe engineer or your supplier immediately (Ofgem, 2026).
How to verify that your meter is correctly installed and sealed
Check that your gas meter has a visible, intact seal from the supplier or network operator — a broken seal is a red flag. For electricity meters, look for a tamper-proof seal (usually a plastic or metal tag) that has not been cut or removed (Energy Networks Association, 2026).
If you have a smart meter, confirm that the communications hub is properly attached and the meter is not showing an “alarm” or “tamper” code. If you are unsure, contact your energy supplier to arrange a free meter inspection (Ofgem, 2026).
The direct answer to “How do I prevent energy theft in my home?”
The most effective prevention is to ensure your meters are properly installed, sealed, and regularly inspected by your supplier. If you buy a property, obtain a meter inspection certificate from the seller or arrange one yourself before moving in (Ofgem, 2026).
If you rent, ask your landlord to provide evidence of a recent meter safety check — gas every 12 months, electricity every 5 years (Gas Safe Register, 2026). Never allow anyone other than a qualified engineer (Gas Safe, MCS, or supplier-approved) to access your meter (DESNZ, 2026).
