What is a 'boiler room'?
A 'boiler room' is a businesses located outside the UK, which tries to peddle worthless shares to unsuspecting investors. These scams target anyone and sound very believable.

How did they get my telephone number?
We cannot be sure how boiler rooms identify their potential investors, but we do know that they use business directories and publicly available registers of shareholders.
Be careful when you are contacted out of the blue and be aware that responding to an ad or by asking for additional information, for instance, gives the callers permission to contact you again with their bogus "special offers".

Can I stop them from calling me?
Once you have been targeted by fraudsters, it is difficult to stop them from calling you. Boiler room operatives are persistent and they may call you again and again, hoping to clinch the deal. Remain firm and terminate conversations early and they'll eventually give up.

How do I know if this is a scam or not?
It's hard to tell whether it is a genuine opportunity or a scam designed to rob you of your savings but use our top tips below to help:
* Consider the approach. Did you invite these people to call you? If not, what is their motivation in calling you, rather than collecting your cash? Are they offering you something special like higher than usual rates of return with very low risk? If it sounds too good to be true, it probably is!
* Check that your firm is authorised by the FSA
* Are you satisfied this is a genuine company? Do they have a proven track record you can verify with an independent party, such as a professional body?
* Ask for additional information from the person who contacted you. This could be company registration documents, terms of business or printed prospectus. Check the company registration against official websites such as UK Companies House or the overseas equivalent.
* Independently research the firm and individual who contacted you and the product they offered. But beware that internet sites are not always what they seem fraudsters can easily set up fake sites.
If in doubt seek professional advice from a trusted independent financial adviser or lawyer.

Can I change my mind?
A boiler room which has cold-called you cannot enforce any agreement against you. If on the other hand you verbally agree to purchase shares from a legitimate firm, the firm may be able to sue you if you decide not to proceed. We therefore advise you to take the recommended steps to satisfy yourself that you are dealing with a legitimate and reputable firm before making a commitment.

Will I lose my money?
If the offer is too good to be true, then it probably is! Dealing with an unauthorised adviser or firm means you don't have access to the financial services compensation scheme should things go wrong.

What can I do?
If you have been a victim of a boiler room fraud, you should retain all material and documents provided to you, such as bank statements and contract notes. You should report the matter to the FSA and also your local police, even if it is only for their information. Based on a number of complaints, the police may be able to assess the magnitude of this fraud. Testimonies by different people will help paint a fuller picture and co-ordinate their actions better. However, don't raise your expectations of getting your money back, as this may prove very difficult indeed.

A company claims to want to buy my shares back should I sell?
It is likely that your name and details have been passed on or bought by another fraudster, pretending to offer you a lifeline by buying your worthless shares. There are many such operations which are sometimes known as recovery rooms. In fact, the only thing they ever recover is more money from the victims. You will notice that before you get any money from them, they require a payment of "a purchaser bond" or "guarantee" or a "fee" of some sort, allegedly to release the shares or to secure the deal. However, after these people receive their "fee", they just disappear and you will probably never hear from them again.
