At 30 March 2018, the Group was committed to making payments in respect of non-cancellable operating leases in the following periods:

The Group leases a number of stores and warehouses under operating leases of varying length for which incentives/premiums are received/paid under the relevant lease agreements. Land and buildings have been considered separately for lease classification. The operating lease commitments are shown before total future minimum receipts of sublet income, which totalled £5.7m (2017 restated: £6.9m). The prior year figures for payments in respect of non-cancellable operating leases and sublet income have been restated by £12.5m to remove intergroup leases.

No leases place any commercial restriction on the Group's ability to conduct its business in the manner it sees fit (for instance restrictions on dividends, debt levels or further leases). No lease has clauses that link rental payments to performance, for instance turnover leases and no lease contains contingent rent clauses. All leases include rent escalation clauses setting out the basis for future rent reviews. Typically these are based on open market conditions or are linked to RPI or CPI.
