Tenderloin-
Boiler: £1500 - 2000 odd. Assuming something in the region of 24KWH.
DPC: £750 - £1000 depending on method. Usually they hack away plaster and inject into brickwork. I think more often that not, the cause can be cured without needing a DPC. In some ways, a DPC can just hide the damp as they may add an impervious layer underneath the plaster. If the gutters are full/fucked then you may have water landing on the ground along the wall which leads to ingress, or water running down the walls which allows it to soak into the brickwork. This also tends to wash away your brick pointing over time. Look for signs of algae and moss externally, near the area of damp and see if you can trace where it comes from.
As you are negotiating, you may want to tell them that you definitely need a DPC, just to help your case by making it sound as expensive as possible.
