Older does not automatically mean unsuitable

Many older homes can work well with a heat pump, but the route depends on the fabric, the emitters and how the system is designed. Age alone is not the deciding factor.

The useful question is whether the home can be made to run comfortably and sensibly at lower temperatures, not whether the house is new or old.

What needs checking properly

A proper survey looks at heat loss, radiator suitability, hot water demand and how the house is actually used. In older homes, those details matter more than generic marketing claims.

That is often where the project becomes clearer: some homes need modest emitter changes, some need more careful planning, and some need improvements before they make sense.
