Ltd is the way to go with been ltd for 5 years now. Yes your accountants bill is more but take it from me my corp tax is low every year never paid more then 2.5k. Yes it also makes you look far more professional when it comes to the larger work (commercial etc) if your just on the residential route then maybe it aint for you.
if you take someone on, limited works in your favourthe limited company is its own identity and you would be employed by 'rwc' as a director, the main reason people set up limited companies is that all debts stop at that company,they cant come after your house etc
Depends on what you are after
i have been cleaning windows for 15 years and have been a ltd for last 5 if your turn over is much higher than a cowboy or a pint n pack of walkers weekenders and you would like to look and feel a pro and do business with other businesses as wel as houses regardless of being vat registered you sould become a ltd good luck
If you have an already established business which is turning over a reasonable amount of money then it is worth going limited. I have recently gone limited with my window cleaning business and have used an experienced accountant to deal with this. Although it costs in fees it has saved me a considerable amount of money already.
