If you have any solar (or other micro generation such as batteries) PV close by that could be pushing the voltage up. Solar/Microgeneration inverters should cut out at around 253v (230v -5/+10%). If that is being exceeded, then DNO may be able to help. If you are more rural there are other factors that my push the grid voltage out of spec, such as transformers being adjusted.
We have microgeneration (so we are part contributing to the voltage) and we are currently sitting at around 251v. Totally within spec and our Gen 2 TWC is quite happy at that voltage - I would be surprised if it wasn't. For microgeneration inverters to export, they need to raise their voltage above grid, which in turn will push up grid voltage. Lots of regs on how they should control voltage to keep things in spec, but in general, lots of output from microgeneration = a higher grid voltage.
You can get plug in voltage meters which will quickly and safely tell you the voltage.
