I'm going to steal a thread from Mike Halliday. Many moons ago he made a very valid point on the pricing issue that a 3 bed semi-detached in London will cost a lot more money than a similar house in virtually any other part of the UK. And because of the higher cost of living, most London workers receive a salary "weighting". So how could a person in the business of cleaning carpets hope to survive in London, charging the same rate as a colleague in Derby, Dunstable or downtown Dunkeld. We are selling a local service, not a nationally distributed branded box of plastic and silicon. And that service differs from business to business as well as from job to job. And don't forget, cartels and price fixing are illegal.
Safe and happy cleaning:)
