Had a terrible experience with this company a couple of years ago.
I viewed a property over looking the canal in sale, was quite interested and the man showing me round said that there were lots of other people interested and that if I gave him £200 he would hold it until I had decided, at no time was I told that the money was non refundable.
The letting did not go through for a number of reasons so I telephoned the northwood office and they told me to come and collect the money.
After arriving at the office I was then told that they were keeping the money, so I refused to leave until I got it but to no avail.
so all in all am £200 down and a lesson learnt, places like this will say and do anything to get a let/sale.
really hope this review helps and nobody else is conned in this way.
