One of the partners called 118118 twice last month – both calls cost £4.50.

That’s a lesson learnt then! It turns out they charge £2pm.

One of the cheapest, if not the cheapest is 118888 – it does the same service at less than half the price – 95p per minute. Hang on – are you with me on this – that is still ridiculously expensive. In fact, as far as I can tell, all the directory enquiry services cost this kind of money

There is a free service – 0800 118 3733 – you have to put up with some adverts, and it’s a robot you talk to, not an human, but I can put up with that compared with the knowledge that it costs about 50p to say ‘No, I can phone them myself thanks’.
