Cable Forum - New customer - any ways / places to get a better deal?

I'm moving out of my parents house in a couple of weeks, they're on Virgin (and will continue to be) and have been customers since about 1997 in the old NTL / Cable & Wireless days.

The flat I'm moving into is a fairly new build, and it's got Virgin and Sky points in the living room, and Virgin have already been on the phone to offer me a deal.

The offer I got was:

- 50mbps broadband
- 12 month contract
- £25 installation fee
- £26.50 a month.

This is essentially the same offer on uswitch, but with half price installation.

I'm just curious to know if there's any way to either get this lowered, or if I can get some extra services in there for around the same price.

I saw that if you use quidco, and an offer on uswitch, you can get the following:

- Big Easy Bundle
- 50mbps Broadband
- 60+ TV Channels
- 500GB Tivo box
- Home phone (unlimited weekend calls)
- 6 Months Free Netflix
Price: £15 for 12 months, then £20 plus £15.99 line rental.
Total over 18 months (contract length) = £587.82
Minus Quidco cashback of £80 = £507.82
Works out to be, on average £28.21 / month

The issue is, I can't commit to 18 months, but I can commit to 12. But it seems the offers Virgin have are all 18 months only.

So it made me also wonder - if you cancel at 12 months (I'm hoping I wont have to as I'd like to stay where I'm moving but cant guarantee it), what's the penalty?

I'm not really fussed about TV or Phone, but if I can get anything else included for around the £25 mark it'd be awesome. Is it worth trying to play them off against other offers for ADSL, or do Virgin not negotiate new customer offers?
