The rate will depend on your customers, if your sat at home then in the current climate your too expensive even if in reality your costs are correct, when times improve ÂŁ30.00 per hour will be fine, at the moment with hardly anything about and large companies charging silly rates to keep their guys working rather than having them washing vans you need to lessen your rate if you want to work, if not then stick with the ÂŁ30.00 and something will come along eventually at that cost but you may not work much. In the domestic sector outside London at the moment ÂŁ30.00 per hour will be the top whack and you will find ÂŁ20.00-ÂŁ25.00 more realistic, my view is to keep the rate low and add 15% onto materials which may get you more work for now. There are guys getting work at ÂŁ30.00 per hour no doubt, but not many at the moment, I find rates fluctuate with the current climate more than I have seen before, thats the state the country is in, if you have a mortgage and need to work then you can't charge ÂŁ30.00 per hour and expect to be really busy unless your lucky, I would suggest you try at ÂŁ22.00 for the next Job you price with a mark up on materiales and see where that gets you.
