So far I have been taking out £200 from the bank each monday. My biggest weekly cost so far has been CL campsites which are averaging £45 per week. I have been staying in one Sunday through Thursday nights and wild camping or staying on my sisters drive on friday and saturday night.
The £200 is overkill as I have been enjoying myself, eating out and going to pub but have still had £20-£50 left at the end of each week. Once I have bought a few more things for the van I will be cutting back on my wages and leaving more to my savings. I think £150 per week is more than enough for me to live happily on in the van. I am spending around £40 per week on food and drink for consumption in the van which I think is stable. The laundrette costs me £5.50 per week. I was buying a gas cyclinder every 7-9 days until the weather turned. The gas was costing me £22 each change. This cylinder however has lasted me 2 weeks so far and is still going strong.
I am down to half a tank of Diesel so each tank will last me around 2 months. This is better than I expected considering I am doing lots of little moves each day rather than long dashes cross country. I am averaging about 10 miles a day currently.
