The alert came came as the firm revealed it bounced back into the black following a 22.9 per cent rise in total revenues to £324.7 million for the six months to 30 September. Underlying profit rose to £1.5m, up from a £4.5m loss last year.
Group chief executive John Roberts said: “AO has made a great start to the year, with group revenue and profits growing well as we continue to deliver on our long-term strategy. We have made progress in our mission to become the best electrical retailer in Europe.”

It also said a subdued housing market could hit demand for domestic appliances.
