Thanks for your help. The battery was new last year, but I've checked it and got the following results (seems ok to me, but I'm no autoelectrcian).
Voltage with battery connected after standing for 24 hours without the engine running and key out.
11.79 volts. May seem low but I had been checking fuses the previous day without running the engine.
With the engine running it was giving 14.1volts. After 5 minutes this decreased to 13.98 volts with the engine running. When I turned the engine off after that 5 minutes, it had increased to 12.73. (from 11.79 volts)
With the battery disconnected it was 12.67 volts.
After leaving the battery disconnected for 1 hour it was 12.42 volts (down from 12.67 volts)
