Thanks all for the advise, I will do the hose test at the weekend from cold, I don't have the A/C on much in the winter keep in ECO the car is cold enough as it is

I had the thermostat replaced when the cambelt was done as it was an easy job to do at the same time along with the water pump, probably a bit too belt and braces because at the time the car had only done 35k miles. Heater has never been good though.
One question on the HBV, I have no water leaks at all, but can the HBV jam and not leak, would the HBV test prove this by disconnecting the vacuum pipe. Not sure if it has much bearing but car has just passed the 54k mark. I had the cooling system flushed when the new rad was fitted earlier in the year, would not that have cleared the crud from the system, tbh made no difference to the heating. Sorry if asking a stupid question but I am no mechanic.
