What do you mean ? G25 modern samples are not perfect nor extensive but you can model your modern ancestry, correctly, with Iron Age and Medieval samples. There is a saying GIGO (garbage in garbage out).
Some people say the English are just 'island (insular) Germans', anyway. So bare with me (anything under a fit of 2 is good). Here is a G25 result using 2 ancient source populations and genoplot :

British population history has been shaped by a series of immigrations, including the early Anglo-Saxon migrations after 400 CE. It remains an open question how these events affected the genetic composition of the current British population. Here, we present whole-genome sequences from 10 individuals excavated close to Cambridge in the East of England, ranging from the late Iron Age to the middle Anglo-Saxon period. By analysing shared rare variants with hundreds of modern samples from Britain and Europe, we estimate that on average the contemporary East English population derives 38% of its ancestry from Anglo-Saxon migrations. We gain further insight with a new method, rarecoal, which infers population history and identifies fine-scale genetic ancestry from rare variants. Using rarecoal we find that the Anglo-Saxon samples are closely related to modern Dutch and Danish populations, while the Iron Age samples share ancestors with multiple Northern European populations including Britain.
