Swansea to Cardiff Gate is a straight run east on the M4, about fifty minutes door to door, and for years that was the closest a Swansea client could get to a permanent polygraph office without crossing the Severn. The bridge tolls are gone but the journey to Bristol is not; our office sits this side of the water, just off junction 30.
What comes down the M4 from Swansea is what comes from everywhere: infidelity questions that have outgrown talking, family money that went somewhere it shouldn't, workplace investigations from the SA1 offices to the retail parks. The examination is the same for all of it. One question agreed word for word, one hour in a controlled room, one answer.
By car: M4 eastbound to junction 30, around 50 minutes from Swansea, with onsite parking at Cardiff Gate Business Park.
By train: Swansea to Cardiff Central takes around an hour, with a short taxi ride out to Cardiff Gate.
Recommended office: Cardiff Gate Business Park, straight down the M4. Exact directions are sent with your booking confirmation.
Not with a permanent controlled office. Operators who "cover" Swansea typically test in hired hotel rooms, which is exactly the environment professional protocols warn against. Fifty minutes of motorway buys examination conditions we control completely, and the £449 price includes no travel surcharges.
Yes. The examiner explains the preliminary result before you leave Cardiff Gate, so the M4 back to Swansea is driven knowing where you stand. The full written report with the recorded charts follows within 24 hours.
For Swansea and the whole stretch west of Cardiff, the nearest fixed polygraph suite is ours at Cardiff Gate, about fifty minutes along the M4 with parking when you arrive. Nothing closer operates from permanent premises. One drive, the examination, the preliminary result before you leave, and the written report the next day: nearer than it first sounds.
