Yes that looks about right. Don’t forget business rates in the U.K.. this is based on a notional rent for the premises which may or may not be close to the actual rent. You pay roughly 50% of this theoretical rent as business rates. If the valuation office’s official calculation £12,000 pa or less you pay nothing (although this may change in future) and there’s a sliding scale between £12;000 and £18,000, if you have more than one salon there’s no discount or “free” premises.
Rent is based on “frontage” and distance from the street front. You pay less for basement and upper floors and ground floor rooms one room back from the street. Ideally you have a narrow and deep shop with an upper or lower floor. You’ll pay a lot less than another salon with the same floor space on the ground floor directly off the street,
You can look up business rates online. It’s public information and you just put in the address. This way you can work out which are the more expensive locations and spot potential bargains. My shop is deep and has a basement. When I first rented I was paying the same rates as my neighbours, but they had a different arrangement of floor space. I gambled that I’d be eligible for a 100% rates discount at the next appraisal (done nationally every 3 years) and I was right. So my overall bill went down by several thousand shortly after I’d moved in, but the rest of the street still had to pay rates.
