In contract discounts coming to an end

[Alan329]

My in contract discounts come to an end in July, when is the best time to negotiate a new deal?  Should I start a month before or wait until nearer the time?  What are peoples expriences of negotiating new deals lately?  Are there still deals to be had or do I need to start tlooking elsewhere?

You have to give 31 days notice to cancel so I would negotiate from then.

Anecdotally, deals are getting harder to find - so have competitor prices to hand to assist your decision and to drive the negotiation.

Based on the experience I have just had, deals and offers are becoming very limited. I have been offered discounts via email from July which have brought costs down, but still an increase on what I pay now. I've had four live chats, most recently today. 
The absolute best I was offered was a further £4.00 a month, but this would have required me to drop to Netflix standard with ads, and a new 18 month contract.

For me it wasn't worth it to save £4 off the non contracted prices, and absolutely no budging on the £20 admin fee. Sign of the times. 

To add, I've just received an email regarding the increases to broadband advising I can leave penalty free early if I should choose too.
