Usually tafsir books have many volumes so I’m not sure is a single physical copy in english. There are many translated tafsir online however.
The best one is done by a professor of English at the University of Tehran, Dr. Ali Quli Qarai. Its also notable in that it preserves the meanings of verses dedicated to honoring Ahlul Bayt, instead of the weird additions by Sunni translators.

I read the Qur'an Arabic my native language, but my husband has the Ali Quli Qarai translation and I think it's excellent. I really like the footnotes on translation choices he makes for certain words, giving you alternative meanings other than the one he may have chosen. It has 2 columns on each page, Arabic on one side and English on the other with a line by line translation and decent but brief foot notes. It's also good if you are learning Arabic or would like to have the Arabic words right there if you want to look things up.
We also have the Study Quran, and it's also a very good translation and also worth purchasing due to the extensive footnotes and explanation of the verses coming from a variety of sources.
The NAV/NIV Bible is supposed to be good - the NAV being the equivalent of the English NIV, and written in a simpler language.
As to the Qur'an, I like Holy Qur'an: Translated by Ali Quli Qara'i "Phrase by Phrase English Translation" , as it uses a method of translation that uses the same English word for the equivalent Arabic word, it's also a good translation in general, but the Arabic is printed in the same "phrase by phrase" pattern instead of just a continuous block of text as you normally get, so you can actually look at the Arabic word by word, sentence by sentence. It's very good.
I read the Qur'an in Arabic, but I bought this translation by Ali Quli Qara'i for my husband. Having read through quite a bit of it, it's an excellent translation and I highly recommend it. He includes footnotes that both explain his translation choices (and any literal translation that had to be rephrased) when needed as well as basic commentary. It also has the Arabic and English phrases side by side, so someone learning Arabic can easily compare the two.
I prefer the translation of Sayyid Ali Quli-Qurai. It's available online on www.tanzil.net or in PDF online: https://zawaar786.files.wordpress.com/2013/07/phrase-by-phrase-quran-with-english-translation-by-ali-quli-qarai.pdf.
I have this version in hardcopy (I bought it here in Iran where books are far cheaper) https://www.amazon.ca/Quran-Ali-Quli-Qaral/dp/1904063179
