Wrong!
Flat rate scheme is a system where you only look at your turnover for each 3 month period and you pay a reduced rate of VAT on that (11% for cleaning, discounted by 1% in first year) regardless of any purchases you have made.
eg:
Flat Rate Scheme
3 month turnover inc VAT @ 17.5% £50,000
VAT due @ 11% £5,500
Standard Rate
3 month turnover inc VAT £50,000
VAT due @ 17.5% £8,750
Less any vat from purchases
Therefore depending upon what VAT purchases you make in that 3 months you could save up to £3,250 in VAT.
Even on the flat rate scheme you can claim the VAT back on purchases over £2000 net (£2350 inc)
In the cleaning business most of your costs, if you are anything like us, will be wages and are therefore not liable to VAT, so you need to be purchasing a lot of equipment in order to make the Std rate scheme better for you than the flat rate scheme.
We saved over £2,000 in VAT payments for the last quarter alone, we still charge the customer the full 17.5% but only pay the VAT man the flat rate level.
