If you check my reply to Chris_B you will see a link to the range of additional benefits on a Full Works Broadband plan, which you can compare to the features of an Essentials or All Rounder plan. Being on this plan and the included features would be one reason for your price seeming high compared to the usual plans which do not include anything additional. The Full Works features include Smart WiFi (Wi-Fi extenders), Smart Hybrid Connect (4G Backup), Cyber Security Multi, included Expert Visits and more which ordinarily are not included on a lower package and would instead come at an additional cost if you wanted to add them.
Unfortunately if you've agreed to the deal you will be subject to that for the remainder of your minimum term.
Towards the end of your minimum term (last 30-90 days) you will be in your recontracting window and able to discuss a more suitable package with EE - downgrading from Full Works at that point will involve the loss of some of these additional benefits and require the return of some of this additional equipment to EE.
