Help with Will

Hi,
I am a lone mother of two infant children (no family support) and I am yet to make a Will - due to my situation everything seems like a mountain and yet also due to my situation a Will is something I desperately need in place to protect my children!
I am seeking help regarding what is the best/cheapest way to obtain a Will/Life Insurance/Funeral Cost etc? (Id appreciate any advice)

I have attempted to do the above via Google etc, Ive even obtained forms in the past, however Ive struggled because there is no one whom I could place in charge - yet writing 'everything to go to my children' seems ignorant and they are only infants.
I also signed upto Polly however I felt bombarded by their phone calls, I thought they would locate the most appropriate cover for me, not contact me with different offers.
I also need to ensure if anything happens to me, my funeral is paid for etc?

Thanks for any help.

Have a look at this guide from Money Saving Expert - www.moneysavingexpert.com/family/free-cheap-wills/

March is Free Wills Month, and most charities will provide a free will in exchange for either a donation on the spot, or a small amount left in your will to them. The Cancer Research UK Free Will Service allows over-18s to get a free will. Might be worth looking at?

Thanks for this, unfortunately Free Wills Month is for people over a certain age.
I did see from this link that the union I am member of may offer free wills however.

Is there any advice re life insurance/funeral costs - what is the best option for me to take?
Thanks

Yep, most of them are for people over a certain age, which is why I highlighted the Cancer Research free Will.

I'd suggest having a look on either Money Saving Expert or on Money Helper (formerly Money Advice Service) for info about prepayment plans and life insurance.
