My 10cents worth
GOOD
Shobdon - Quick for fuel, friendly staff. No hassle
Kemble - Self serve avgas, nice people. Good opening hours
Lydd - Guy's with a browser fill you up while you go for a coffee. Found the guy's in the aero club very helpful in planning my first cross channel flight... 5*
Caernarvon - ask for fuel on the way in, land at the pumps and they will be waiting to fill you up. Happy bunch, no hassle
Turweston - great service. Even gave as a lift to Silverstone to watch the racing.
Pembrey - good service, friendly. Uses a browser to fill you up. Just a pain for operating hours being in the middle of a danger area.
Blackbushe - Good all round
BAD
Swansea - No chance of fuel if air Wales flight is due in/in/due out. Pump always blocked by fixed wing, so land shutdown and push. Runs out of avgas quite often. Cafe is a rip off.. And closed on a Saturday. Airfield closed on a Tuesday.. It’s a joke
Cardiff - No avgas from airport only flying school who runs out quite often. If you land at airport not the flying club be prepared to get hammered for handling.
Denham - Most unhappy man in history on the radio...!
