Is the cavity wall? Insulation is the best solution.

Are the Gutters perfect, no drips?

Hi, yes it's a cavity wall - we believe it's previously been injected with spray foam insulation long before we purchased the property. However, the issue is occuring on multiple walls on both sides of the property - so not ideal. We've inspected the roof, gutters etc and can't see any signs of leaks or drips, which is quite fristrating.

Our joiner suggested we could line indoor walls with further insulation, however, we're reluctant to do this as we'd lose quite a bit of space.

+ 1 for Nuair Drimaster 
Have had it in both the house, installed it myself a few months ago.  
I don't think this is going to be the magic bullet but will be part of the solution.  A dehumidifier would beneficial.  

Thanks for the feedback -  Did you go for the model which included a heater and how many vents into your house did you go for? We're debating whether we need that option or not. Have been running a dehumidifier too, but it's filling up too quickly.

Had a Nuaire Drimaster for over 15 years absolutely brilliant bit of kit.
Fitted it myself cheap to run & works well.

Thanks for the feedback. Did you go for the model that included a heater? We're debating whether that's required. Also how many vents into your property did you fit? We've been advised that we could fit one central vent into our hall, or additional ones into the affected rooms. But given that these are bedrooms, I'm reluctant to have cold air pumping into them at night.

The models with heaters in are optional to run them but hardly make a difference and cost about £3 to run from a test someone on here did

Ours was filling up quickly first couple of weeks, but then it slowed down. I think this is because humidity saturates everything in the house, walls, ceilings, furniture etc. Once the house is dry, it only has to deal with whatever humidity we produce breathing/cooking/ drying clothes/outside air.

Don't forget that by regularly ventilating you introduce humidity in the house - outside air contains lots of moisture in our climate! Obviously people do have to ventilate but only to the extent that it is necessary to ensure supply of fresh air.

For example it is only 2 of us in the house, and the ventilation is limited to opening window in the bathroom after use, and doors opening/closing (relatively often due to dogs). This appears enough as the air in the house never feels stale or less than fresh in any way. A house with more people will probably need more ventilation.

We run dehumidifier almost every day, with the result that there is no condensation on the windows now, and humidity level is maintained at about 40-50%. Prior to buying the device, our humidity was 74% and condensation on the windows which was quickly turning black.

We installed a Drimaster LC two weeks ago, has made a massive difference. While it was very cold it did make the landing cold but I've since turned it down from setting 3 to 2 and obviously it has warmed up a bit outside, so it's not that noticeable the last few days. One vent on the landing, not seen anyone doing more than one and no one putting them in bedrooms.

Researched the unit for about 2 years before finally getting one, but running the house cooler this year has inevitably meant more condensation, and wish I'd got it sooner. Yes you can open windows etc every day and probably have the same effect but it's great just knowing it's up there doing it's thing without me being to do anything at all.
