I'd go with whatever Airhead suggests, but I'll just add that for the cracks in my living room where there was movement (we are near the overground which doesn't help) I scraped out the cracks with a shavehook and then filled with Red Devil One Time.
I think I'd be a bit disppointed if I paid someone to install a DPC and this happened. I guess either there's been movement or the plaster has shrunk. The radiator may exacerbate this.
Yeah, I was pretty peeved when I first noticed it. Called the guys out that did the DPC work and they pretty much said that there was nothing they can or will do about it.
Really appreciate the advice its a massive help @Airhead@rodabod
