A new survey has found that many services carried out in the North are on average between 25% and 45% cheaper than the same services in the Republic.
The study is published in the Consumers' Association of Ireland's magazine Consumer Choice. It found that the cost of a car service in Belfast was on average 45% cheaper than a similar service in Dublin, while the cost of a gas boiler service was 33% more in Dublin than Belfast.
There were similar disparities found in the cost of dental, driving instruction and chiropractor services.
The chief executive of the association, Dermot Jewell, said the findings underlined the point that some service providers in the Republic were still not getting the message that prices here need to fall.
