Extreme Locks Ltd.

Not a transparent service. Taking an upfront 'booking/deposit/call-out' fee for the simple job of ringing someone else to do the job! And then the so called local contractor doesn't make contact.
Refund not forthcoming.
Advise you avoid

These people (aka Extreme Locks) said they would get a locksmith out to see me in an agreed time window. The locksmith never appeared. I tried to rearrange. They didn't call me back. I got someone else to do the job, and phoned them asking for a refund. The money didn't appear in my account. In all I had to ring several times over a two month period. Each time I was promised the money would be paid. It was, of course, always someone else's responsibility. I had to persist and persist, and in the end two months later I got my £50 back. Is it a scam? I don't know. But if you wanted to run a scam, £50 is about the size of sum that's big enough to be useful for a fraudster yet small enough for a lot of people to give up trying to recover it. Why take the chance? Avoid like the plague.

GREAT SERVICE! Quality, Value, Professionalism, Punctuality.The service was excellent very fast unreliable. Would recommend him to anybody that needs locks THANK YOU! 5 +++++
