This website has a lot, if not all of mosques in the UK as well as classification of madhab, sect etc. It uses the Google Maps API so the Google Map link is embedded and can be easily extracted, along with all the other fields that have been listed.
This is a message from a brother I know who does a lot of work online: *NEED URGENT HELP* Salam. I need the location data of our mosques round the globe. Send me google map locations of your local Sunni mosques ASAP. Main criteria is that it has to be a Confirmed Sunni Mosque. It can be Hanafi, Shafii Hanbali Maliki mosque. Those well-versed with excel, send an excel sheet containing Mosque name, Area, City, Country, and most importantly Google Map Link.
