Yours please 
A few of ours that have worked:
1/ Sky
Just spoke to the accountant who said to ring up Sky and threaten to leave as they always reduce your monthly bill for 6 months at a time. My package was £19pcm.
Just rang and now get Sky+ with 2 packages for £14pcm, with a one-off reduction to £9.99 next bill, so over 6 months this is £39 I would not have had-towards the Omega.
2/ Water bills
Welsh Water will now let you trial a water meter for up to 12 months and remove it again if you want them to. In our experience, meter saves 20%-so worth a try?
3/ Mobile phone; as per Sky, threaten to leave-we have kept our phones and gone onto "SIM-only" which costs us £45pcm for both of our phones, unlimited call and text.
4/ Insurance premium fees
Save up for any insurance (car/house etc) and pay in one payment to save interest charges and fees
5/ Discount vouchers
Before buying anything always search for the item with "discount voucher" "discount code" plus the title of the item. By searching "Stena discount code", we saved £40 on Stena Line Ferries with an Axa insurance offer; no-one ever checks your eligilbility. We got a new Beko washing machine delivered for £129 and new tomtom for £89 a while back. Always worth a few minutes.
We have hundreds of these as we live on the furry bits that fall off the shoestring 
What are your best money saving tips?
Anything (legal!) that can help others?
Use Freesat and.or Freeview
Also use affiliate sites such as Cashback Kings and Quidco
We had freesat for years, but moved house (no aerial fitted) and Sky+ were doing free install, box etc if you had the £19 package-had this for 1 year, went to go to freesat and rang as above, but feel Sky+ and the 2 mixes worth £14pcm.
Freeview is cack around here!
If moving into a (usually new) house without an aerial, just do a free sky install on the cheapest package for a year, then revert to freesat after the year-it is cheaper than fitting a digital aerial and box 
No its not....a top notch digital aerial setup is around 70 quid with mast etc....its the rip off merchants who do th fitting that over price it and fit a sub 20 quid antenna.
And there is no such thing as a digital aerial......again miss sold.....it is but a wide band aerial (not easy with a yagi and hence how log periodics have grown in favour again)
Yes. I wonder how much money has been made from that one.
My terminology-apologies
We are in poor freeview area, as Leominster is in a "bowl" so the local fitters had to replace our first aerial with something that picked up freeview and cost £130, plus the box which was then £50; £180-you're right though 12 x £19 = £228.
My original thoughts were based on the first time I did this and paid £14pcm for Sky including free box which came to £168, so a bit cheaper and much better reception and quality box/remote.
I'm guessing this is a local thing then, if you can all get good freeview? I'm no aerial expert but this worked for out cheaper us, but we live in a poor reception area
