Fee Split and Reserve Calculator: England and Wales

Split a small building's yearly budget by each owner's share, check the reserve against the legal minimum where England and Wales sets one, and total a simple reserve plan.

Split the yearly budget

FlatProportion in the leaseSharePer yearPer month
Flat 125.00%£3,750£313

Each flat's share of the service charge and any reserve fund is set by its lease. Works costing a flat more than £250 need section 20 consultation first. Enter each owner's figure from the title documents; equal numbers give equal shares.

A simple reserve fund plan

List each shared item you will have to replace, today's cost and the years it has left. The yearly figure is the cost divided by the years, with no allowance for price rises or interest.

Columns: item, cost today (GBP), years left.

The plan needs £4,542 a year. Your budget puts £3,000 a year into the reserve fund.
