Dunelm boosted sales 12.5%, from £315.2m to £354.7m, in the year to end June.
Like-for-like growth at the homewares retailer was better than expected at 6.1% as a result of strong third and fourth quarter performances, up 4.7% and 10.1% respectively. The company attributed the figures partly to the wet weather, which had led to a shift in spending patterns.
Margins remained strong and profits are expected to be at the top end of expectations.
Dunelm opened four superstores during the year and relocated one, whilst three small units were closed. So far in the current financial year five units have been acquired.
Chief executive Will Adderley predicted that recent rises in interest rates would mean growth in existing stores would be harder to achieve in the months ahead.
