Narrative:

Upon departure; weather reported at hxd was winds out of the north; ovc 011 with visibility of 10SM. Captain was pilot flying and first officer was pilot monitoring. Takeoff; climb; and cruise were normal. We set up for the RNAV (GPS) to runway 3; winds out of the north. Approach control gave us a descent down to 4;000 ft. And shortly thereafter; approaching 10;000 ft. On our descent; they told us 'GPS signal unreliable in the area; set up for VOR-a'. High workload environment; now below 10;000 ft.; the first officer (pilot monitoring) set up the approach and briefed it for me as well. The jeppesen approach plate for the VOR-a has an MDA of 800 ft. Which we briefed and flew into our otherwise normal flaps full landing; instead of our SOP prescribed 1;000 ft. MDA for circle-to-land approaches; which the VOR-a approach is. Also would like to note there were no notams of GPS signal unreliability. There were several casual factors. It was my first time flying into hxd. Quick flight; set up the approach we thought we were to shoot into the airport; then had a quick change of the approach in a high workload environment. It is an approach we don't normally shoot; combined with a short runway I have never been to before. The first officer had been once before. We saw the published MDA shot the circle to land approach at the published MDA; in visual conditions. We debriefed after the flight and both realized our SOP minimums for a circle to land are higher. High workload was the main cause I would say. [I suggest] not many approaches to be flown into hxd. I would suggest a note [in our manual]; published MDA may be lower than company MDA. Also; it is always ok to ask for delay vectors to make sure we are executing our duties safely and correctly.

Title: Air carrier flight crew reported a late change from the RNAV (GPS) Rwy 3 approach to Hilton Head to the VOR-A circling approach; with an MDA very close to the reported ceiling; due to a reported loss of GPS signal.
