We are looking to move into a new premises in the near future. Our current premises is eligible for the full small business rate relief so we pay no rates. The new premises, however, has a rateable value of £13,500 which means we will need to pay around £270 per month in business rates. The new premises has a ground floor and a mezzanine floor and both have their own secure doors once you get inside. At present, the mezzanine floor is listed with VOA as 'internal storage' so has a fairly low rateable value, but if you take off the mezzanine floor and two of the four parking spaces, the rateable value for what's left would drop just below £12.000 and as such would qualify for full small business rate relief. So, my thinking is that my wife and I are directors of two ltd companies, so were thinking Company A could occupy the ground floor and Company B could occupy the mezzanine floor. We have also negotiated terms in the lease to say we can sublet the mezzanine floor to anyone we choose so this wouldn't be an issue for the landlord. I have spoken to VOA and in principle what I'm proposing is doable. The lady on the phone didn't seem to think there would be an issue with my wife and I being the directors of both businesses, but I'm just looking for opinions on whether you guys think this is worth exploring or any experience you can share? My main concern is that before we move in, the landlord will be converting the mezzanine to office space so if VOA come out and reinspect the property and then decide that we can't split it, we could end up with a new rateable value of more than £15,000 which would make the property unaffordable.
