Halfords warned today its 2019-2020 profit would be slightly lower than forecast as UK economic and political uncertainty took its toll on sales of more expensive bicycles and in-car technology in recent months. 

In May, Halfords reported a fall in 2018-19 pretax profit to £58.8m and forecast a flat outcome in 2019-20. 

But today it said it was now anticipating an underlying pretax profit of £50-55m. 

Halfords shares were down 3.3% today, extending year-on-year losses to 53%, after it said that in the first 20 weeks of its first half year like-for-like revenue fell 3.2%. 

"Our guidance assumes that we continue to see the weaker customer confidence that we've seen over the last three to six months," chief executive Graham Stapleton told Reuters. 

Consumers were particularly delaying purchases of adult bicycles costing £200-400 and car technology items of £100-300, Stapleton said. 

Industry data published this week showed British retailers saw their sales flat-line in August as shoppers cut back on non-essentials. 

Economists say recent signs of a weakening in spending by households raise the risk of a recession as the country prepares to leave the European Union. 

Halfords blamed cooler, wetter weather than the same period last year and weaker consumer confidence for the weaker-than-expected performance. 

It said the sales fall was partially mitigated by stronger margins and tight cost control.
