About 18 years ago I decided to get a small patio laid. I rang and asked for quotes - I knew what it should cost, roughly £300, and I still remember the smirk on the face of the man who quoted me £600.
In the event, word of mouth got me a young lad who did it for £180, with I later discovered, equipment temporarily borrowed from his workplace (!)
The patio has been trouble free. I hope my handyman made a career for himself in business where he didn't have to borrow.
I've had the frustration of having to pay for a new floor to ceiling double glazed window because I couldn't get someone out to repair the window latch.
When I wanted my kitchen sink, worktops and doors replaced I went with a company that specifically advertised this service. No problems at all.
I got my plumber by word of mouth and although I'm told he's not the cheapest, he has been wonderful.
One company I would never go with again for boiler maintenance is British Gas. I paid a large sum of money for emergency callout cover and for a regular annual service. My annual service was cancelled five times, at vast inconvenience to me and my complaints fell on deaf ears.
In the end I had a new boiler fitted which came with 2 years maintenance.
British Gas were MOST surprised that I cancelled the maintenance agreement. Appalling customer service from what is supposed to be a market leader.
When I discovered that they were behind my energy company I was horrified, but can't escape the contract without penalty. I'm just waiting to see what they do...
