The age of the house is not enough to decide. A room-by-room heat-loss assessment should show the heating required, the suitability of existing emitters and pipework, and useful fabric improvements. Ask the designer to explain what is essential for the proposed system and what could be done later. Traditional construction also needs appropriate moisture and ventilation advice.
Join the discussion: What is the wall construction, current heating system and insulation condition?
Suggested next step: Book a property assessment before accepting a blanket yes or no.
