My standard hourly is actually a fair bit lower than that, but then that's on-going projects and/or not for clients in London (so I voted £100+)
Edit: And of course to UK companies that's excluding VAT - If you're a UK freelancer and you're not VAT registered, do it now.
A lot of people think you have to turn over £79k / year before you can be VAT registered, but that's not true, £79k / year is when you have to become VAT registered. My first ever business had a turnover of exactly £0.00 when I VAT registered it.
If you're selling to other businesses (and not the general public) it's always better to be VAT registered :)
