Still, he noted that "market conditions were challenging through the year with deflation in grocery of -2.6% and subdued demand in non-food".
That was reflected sales figures: Waitrose's like-for-like sales slipped 1.3%, while gross sales were down 0.7%. At John Lewis gross sales were 2.8% higher, but overall, group revenue was up just 0.5% at £9.75 billion.
The new year has started better, the company said, with John Lewis' like-for-like sales up 3.6% in the first five weeks. Waitrose has managed a 0.4% rise excluding petrol but the "market remains challenging" - something echoed by Morrisons in its full-year results also published on Thursday.
Mayfield struck a confident note with outlook for the year ahead.
"Conditions in the market will remain difficult, especially in grocery. However, given our continued investment in both our operations and the customer offer, I expect sales in both Waitrose and John Lewis to continue to perform comparatively well against the market."
