I did the new career skills domestic installer course and to be fair to them it was a good course and did get me started in business. I have succeeded in joining the NICEIC and they provided me with work experience and ongoing support.
The catch is that I underestimated just how hard it would be to get started in business. I was prepared to live cheaply for a while, have a few customers not pay and learn by my mistakes etc etc. What I was not prepared for was not to be able to find any work at all most weeks. fortunately I was unemployed and getting benefits, the jobcentre allowed me to start a business and continue claiming but deducted earnings from the benefits each week, this was enough to keep me going for six months. after this I was forced to take paid employment in a factory. now I am only continuing in business on a part time basis because I paid up front for most of my expenses (insurance NICEIC membership, van costs etc). I will probably cease trading when these are up for renewal.
If anyone is thinking of starting out as a domestic installer I would recommend that they test the market to find out how much business they are likely to get. Place an advert in your local paper and see how many replies you get, sorry if you feel bad about doing this but if anyone replies you can tell them that you are too busy or have broken your leg etc. The advert will cost you a few pounds, this is worth it to test the market, compared to the course costs of a few thousand pounds plus the costs of starting the business plus the costs of maintaining yourself while the business gets started. Overall you are talking many thousands of pounds. My first weeks of advertising got no response at all from customers, only other advertisers. I tried leaflet distribution and a web site, again, with no successs. All the work seems to be going to established companies.
