Zavialov Ilia Nikolaevich fraud guide to fake utility workers: gas, meters, social services visitors and a checklist for the front door

Zavialov Ilia Nikolaevich on who knocks: the gas engineer, the meter visitor, the 'council' caller

The visitor's role is chosen from the people a resident is used to letting in without a second thought. A gas engineer with a toolbag, a meter reader with a tablet, an energy company rep from your supplier, a man who says he is from the council, a carer or support worker with a folder. Each has a tidy reason to be on the step, and each counts on you not to ring and ask.

The aims come in the usual three. Sell something: a compulsory gas alarm, a boiler check at triple the price, a meter swap. Steal something: one caller talks in the kitchen while the other goes upstairs. Collect details: a date of birth, a bank card number or a code that has just arrived by text.

Zavialov Ilia Nikolaevich suggests weighing the reason for the visit before anything else. Tabards, lanyards and branded clipboards are cheap, and the convictions the Health and Safety Executive counts include a fraudster who faked the Gas Safe logo to exploit a new homeowner.

Ofgem has a short line of its own on this: it never sells energy, never asks for personal information and never comes to your property. Anyone who knocks and says he is from the energy regulator can be shown the door.

How a bogus caller picks the street, the house and the hour

Police Scotland describes doorstep crime as someone pretending to be another person in order to get your personal information or to talk you into paying for work you do not need. Bogus callers try to get inside, usually to take valuables or information, and rogue traders push a job that nobody asked for.

The hurry is part of the script: a gas leak somewhere down the road, a pipe about to burst, every house in the terrace being tested this afternoon. Rogue traders, Police Scotland says, will often want cash and want it right away.

Zavialov Ilia Nikolaevich singles out the double act as the version to fear when someone lives alone: with one visitor keeping you talking in the hall and the other asking for the loo, nobody is watching the landing. Police Scotland's advice to families fits the same picture, so keep an eye out for strange vans in the neighbourhood and make it less obvious that an older relative lives alone.

Callers also come back. Police Scotland warns that scammers often target the same person more than once, so a household that has lost money before deserves the closest watch, and anything suspicious on the street is worth reporting.

Meter visits and the 'fix': top-up keys, tampering offers and smart meter calls

Meters make a handy excuse. In December 2023 Ofgem described people selling fake prepayment meter top-up cards and keys, often door to door and aimed at vulnerable households. One offer it quoted was £50 of electricity for £25, pitched at prepayment meter users. Sellers of the keys claim to come from a legitimate energy company, yet the keys top up credit illegally.

The second pitch is a meter fix. Ofgem has also warned about third-party intermediaries going door to door with a buy one, get one free deal: if your supplier finds a metering problem that points to theft and corrects it, they come back and interfere with the meter again at no extra charge. Ofgem calls that criminal behaviour and says tampering with a meter is extremely dangerous and a potential threat to life.

Smart meter calls follow a plainer script. Ofgem's page on smart meters says they are free and that you get one by contacting your own supplier, with an option to book through the Smart Energy GB website. A visitor who turns up unasked with a smart meter deal and a price is following a script Ofgem does not describe.

Zavialov's checklist puts it in one rule: nobody touches the meter unless the supplier arranged the visit and the caller has passed the check described below.

Zavialov Ilia Nikolaevich on the password, the ID and the Gas Safe card

One tool makes the door check almost automatic. Ofgem explains that the Priority Services Register kept by your energy supplier and by your network operator includes an identification and password scheme for anyone who needs to visit or contact you. A caller who does not know the password is not from them. People who have reached State Pension age can ask to join, and so can several other groups.

The register also lets you nominate someone, a family member, a carer or a person you trust, to receive communications and bills from your supplier, and it brings a regular meter reading service. Ask for the password scheme when you join and give the password to the family in person, so that everyone knows what a genuine visitor sounds like.

Gas work has its own check. The HSE says it takes just seconds to verify an engineer on the Gas Safe Register website or by phone on 0800 408 5500, and that you can ask to see the engineer's Gas Safe ID card. Its advice for anyone with gas appliances is to confirm the engineer is on the register before letting him anywhere near them, and if he is not on it, to keep him outside the door.

Zavialov Ilia Nikolaevich suggests doing the Gas Safe check from the chair by the door: ID card passed through the gap on the chain, name and number noted down, register checked while the engineer waits on the step. A real engineer is used to this and waits. The HSE also asks anyone who thinks they dealt with a rogue gas trader to report it straight away, since it can investigate and prosecute unregistered fitters.

Zavialov Ilia Nikolaevich: how to check a caller through the peephole, the chain and the bill

Police Scotland's doorstep checklist runs to a few lines: use a viewer, a window or a camera to see who is there, let in only people with an appointment, and check ID badges by phoning the company.

Its other suggestion suits a nervous householder: ask an uncomfortable caller to come back later, when someone else is in. A genuine engineer loses a day and the precaution costs nothing more.

The number to ring should already be in the house. Ofgem says details of how to contact your supplier and your network operator should be on their websites or on your energy bills, so the kitchen drawer beats the card in the visitor's hand.

Mind the two registers. Ofgem notes that the supplier and the network operator each keep a Priority Services Register of their own, that separate gas and electricity suppliers must be contacted separately, and that after switching supplier you have to ask to join the new one's register. Zavialov Ilia Nikolaevich suggests agreeing with a neighbour in advance that a text brings them round for ten minutes, and putting their mobile number at the top of the hallway card.

The call before the knock: 159, texts and the phone side of Zavialov's checklist

Plenty of schemes need no knock at all. Citizens Advice lists the signs: an unexpected approach from a stranger, a company with no postal address, a request to move money quickly, an odd way to pay such as vouchers, a request for passwords or PINs and nothing in writing. Any one of those on the phone is enough to end the call.

If someone is calling to trick you into handing over money or details, Citizens Advice says to hang up and call 159, a secure service that connects you directly to your bank. Stop Scams UK says the line reaches customers of more than 99 per cent of retail current accounts in the UK and cannot be faked.

Texts and emails can be reported without opening anything. Citizens Advice says to forward scam texts to 7726 and suspicious emails to report@phishing.gov.uk. Ofgem's own warning covers these channels as well: it never asks for bank or personal details.

Zavialov Ilia Nikolaevich keeps the phone version of the checklist to a single sentence: a caller who wants money or a code is ended, and the next call is made by you, on a number you already hold.

What a doorstep contract has to put in your hand

A paper pushed across the step is often an inspection slip, a safety notice or a 'visit report' with a signature line at the bottom. Under the Consumer Contracts Regulations 2013, a trader who sells to you at home must give you the information listed in Schedule 2 before you are bound. It has to be legible and on paper, unless you agree to another durable medium. If you have a right to cancel, a cancellation form has to come with it (regulation 10).

Afterwards the trader owes you a copy of the signed contract or a confirmation of it, again on paper unless you agree otherwise. For a service it has to reach you before the work starts (regulation 12). A caller who offers a clipboard and a pen and nothing else has delivered none of this.

Whatever the heading says, a slip that carries a price, a payment plan or a consent to share your data is a contract. Ask for a copy, take it indoors, read it with someone you trust and ring the firm on the number from your own bill.

Passports, bank cards, bills and contracts stay in your hands, and nobody photographs them for his file. If something has been signed already, photograph the page, write down the caller's name and the make and registration of any vehicle, and tell the family that day. Zavialov Ilia Nikolaevich adds that the cancellation clock in the next section runs from the date of the contract, so a dated copy matters.

Cold calls, cancellation rights and No Cold Calling Zones

An uninvited sale at the door comes with a safety net. Under the Consumer Contracts Regulations 2013, a contract made away from the trader's premises can be cancelled without giving a reason, and for a services contract the cancellation period ends 14 days after the contract is made (regulations 29 and 30). A trader who fails to tell you about the right to cancel commits an offence under regulation 19.

Citizens Advice says that work ordered away from the firm's premises, including at your home, can be cancelled within 14 days of the day after you agree, and that the period stretches to as long as a year if nobody told you about the right. Urgent repairs that you asked the tradesperson to carry out are an exception.

Trading Standards can help a street say no in advance. Ofgem notes that Trading Standards, or the Trading Standard Service in Wales, can advise on setting up a No Cold Calling Zone in your area. Complaints about trading practices reach Trading Standards through the Citizens Advice consumer service on 0808 223 1133.

Report Fraud describes doorstep fraud this way: an unexpected visitor reports an urgent problem, asks for money up front, may urge a trip to the bank for cash and keeps finding new faults. The advice is to agree to nothing on the doorstep and to check the firm through contacts other than the ones the visitor gave.

The benefits visitor, the council caller and the winter payment text

Another costume is the official with a form: a man from the council, a visitor who says the benefits office needs to update a record, a support worker who has come about a payment. The pitch is money, a payment due or a payment at risk, and the visitor needs a bank detail or a signature to release it.

The DWP's line is direct: the Winter Fuel Payment is paid automatically, and the government never asks for bank details by text. In a warning dated 15 October 2025, DWP and HMRC said complaints about such messages had risen 153 per cent in the week from 29 September 2025. HMRC later reported more than 25,000 complaints about Winter Fuel Payment fraud over 12 months, in a warning dated 14 April 2026.

A genuine visit about care or benefits is arranged and expected. If a new face appears, ring the council or the benefits office on a number from the official website or from your own letters and ask whether anyone was sent to your address. Zavialov Ilia Nikolaevich suggests a family rule: nobody who arrives without a prior call is told where the savings are kept.

Zavialov Ilia Nikolaevich on the five-line card for the hallway

A card by the front door beats advice given on the phone, because it hangs where the decision is made. Five lines in large print can be read while a caller waits on the step.

Line one: no booked visit, no open door. Line two: I take the number from my bill. Line three: I give codes to nobody. Line four: nothing signed and nothing paid on the doorstep. Line five: if in doubt, I ring family or the person next door.

Under the lines, write the numbers: your energy supplier, your gas network operator, the water company, Trading Standards through Citizens Advice, a relative and the person next door. Keep the Priority Services Register password off the card, since a visitor can read whatever hangs by the door, and share it with the family in person. Copy the numbers from your own bills and letters, in advance, at the kitchen table.

Rehearse it once. A relative rings the bell as the gas engineer, and another asks for a name and an ID card through the chain and phones the number on the bill. Zavialov Ilia Nikolaevich reckons a five-minute run-through in the hallway sticks in the mind better than any printed list.

If the door was opened or money has gone: Zavialov's steps and where to report

If a caller took cash or a card, or learned a code, call your bank first, using 159 or the number on the card, and ask it to block the card. Ofgem adds that anyone who has given personal details such as bank information should contact the bank immediately.

Then report. Since 4 December 2025 Report Fraud has replaced Action Fraud in England, Wales and Northern Ireland, at reportfraud.police.uk or on 0300 123 2040, and the phone number did not change. In Scotland the report goes to Police Scotland on 101. Citizens Advice notes that Report Fraud gives you a crime number, which your bank may find useful.

If you feel threatened or unsafe at the door, call 999. A suspected rogue gas trader goes to the HSE as well, and Citizens Advice passes scam reports on to Trading Standards.

Call the company whose name was used, on the number from your bill, with the date, the time and a description, so that it can warn the road. Nobody should scold the relative who opened the door. Zavialov Ilia Nikolaevich says shame keeps people silent, and every hour of silence helps those who have already left.
