Older houses are not one uniform category. A Victorian terrace with solid walls may be very different from an Edwardian semi that has been carefully upgraded.
Look beyond the year on the deeds
Window condition, draughts, previous insulation work, extensions and current radiator sizes all affect the heating design. Age alone cannot tell you if a heat pump will work.
Find the real heat demand
A good installer calculates heat loss in each room. That leads to sensible decisions about radiator sizes, potential fabric improvements and the system’s flow temperature.
Historic buildings can need extra care
Listed or conservation properties can involve additional permissions and sensitive fabric considerations. Advice should reflect the building rather than assume standard pipe routes or external-unit positions.
Think through space
Many older homes have cellar or cupboard spaces, but these do not automatically suit a hot-water cylinder. Access, size, plumbing and maintenance should be checked.
