No problem Yorkie, I thought that would be the case regarding links to a website, but have updated my profile
if that is not allowed just let me now and i will delete it.
I always take online reviews with a pinch of salt, most reviews are left by people that have had a bad experience, not a positive one. But when offers like the bulb one are there, lots of positive reviews follow (for obvious reasons). These offers were cracked down on by Ofgem a few years ago, but seem to be coming through again now
Having seen the recent rises in wholesale energy costs, even though the big 6 have just announced increases of around 6%, there will be more increases on variable tariffs later on in the year. There are deals out there that are cheaper than Bulb or tonic, but again with smaller suppliers. In fact you can get deals that are fixed for the same price as bulb (give or take a few pounds a year depending on you usage) but again with smaller suppliers.
Whoever you go with, i always recommend to give monthly readings to them (if you don't have a smart meter) to ensure you can see exactly hoe much credit/debit you are with them, and ask to change your payment plan accordingly.
My advice is to fix prices for as long as possible, because due to all the various market factors, prices will keep rising for the foreseeable future (won't bore everyone with all the reasons, but it's actually quite scary how much they are likely to go up over the next 5 - 10 years - think energy efficiency!)
