How much does it actually cost to split the title on a block of flats?
On a typical six-flat block, the professional costs come to roughly £1,100 to £1,900 per flat: legal fees for the leases, Land Registry fees, lease plans, lender consent and EPCs. In our worked example that adds up to £9,235, or about £1,540 a flat.
The bigger numbers usually sit elsewhere. Exiting the block finance, stamp duty and the structure you choose can outweigh all of that, and HM Land Registry is taking around nine months to register new leases unless you expedite.
