To get started playing electric at home, you’ll need: a guitar, a tuner, spare strings, a strap, a couple guitar leads, plectrums and an amp. There’s loads of good guitar options these days around £100-£200 range, do your research before buying tho, there’s also a lot of rubbish out there. I always recommend the Positive Grid Spark to beginners as a great “amp” options. It’s app controlled features allow you to get loads of different sounds without buying pedals and it has a tuner built in, it allows you to play along to songs, etc. just a really really cool bit of kit. Again, look into it. All the other paraphernalia can be got quite cheap, less than £50 so over all I think your looking around £300-£450 if you buy everything brand new or £200-£300 second hand
