are they in a really bad state and are rubbish, if so your local Council will take them for you for about �20. If they are still in a reasonable condition, why don't you consider either offering them to a Charity such as St Luke's Hospice which take larger items or consider joining Freecycle and give them away to someone who could make use of them, that way you are reducing the amount that is dumped in tips and helping out someone in the process.
Thanks for your message. Unfortunately, I don't drive and as our flat is on the third floor (there is a lift) not sure someone would be willing to collect.
