i have had a very small condensation problem in the past, but this year it has increased dramatically, to the point i am thinking getting a dehumidifier, we are doing nothing different, have to dry clothes , 4 of us  and cooking .

no idea why its worse that the last 18 years in the same place

anyone recommend a good dehumidifier?

We have had cavity wall insulation installed earlier this year, since which time we have also had a problem with condensation on the inside of our modern, double glazed windows.  We have to leave them all on "trickle" now to stop it happening.   Houses need ventilation and while insulation is a good idea, I'm beginning to wonder whether it was a good move.

Has the OP improved the insulation in the house and perhaps this would account for the problem?

The house was empty for most of this year so maybe once it has 'warmed up' it will be better. The poor windows are probably a big factor though. I don't think there is cavity wall insulation (how do you tell?) and the loft insulation isn't very thick. Thats the next job.

It depends what sort was used. An easy way to tell if foam was used is to go up into the loft and have a look where the joists rest on the outside walls and there is usually excees foam. You could always carefully remove one of the bricks on the outside wall and that would expose any cavity material.
