The prices of fibre broadband will vary drastically, and this depends not only on the prices of each provider but also on the different packages that they offer.  As a general rule of thumb, the slower broadband speeds will likely be a few pounds cheaper a month than the next tier of service.  On average, the UK household spends between £30 to £45 on fibre broadband, although it is possible to get it a lot cheaper depending on the speeds and packages that you get.  The best fibre broadband packages will likely cost around £20-£30 and represent good value providing that you're happy with having relatively slower speeds.  If you're getting FTTP Fibre, this will likely be a lot more pricey, as it will be giving you access to some intense internet speeds.  When looking for fibre broadband deals, be sure to compare various providers as the prices can be extremely drastic and different.
