No, I am agreeing with you Matt. They are a massive brand and they do provide low prices. << This part might be their down fall though!
Even if they paid the person carrying out the clean a whole £10 an hour, the quailty of the work will be brought in to question on more than one occasion. Thats not mentioning all the problems you'll encounter if you rush a job i.e. drenched carpets and upholstery, smells, shrinkage, bacteria growth, colour bleed, leaving items to high a ph etc etc
The only way they could do it would be to go in to partnership with the likes of chemdry, and take a comession for every job generated. But with the prices chemdry charge.... maybe not right for your average Tesco penny pincher type customer lol
