What a good decision needs

Heat demand, heating system, hot water and your priorities.

A useful route should account for more than a headline product price. It needs to consider how your home loses heat, how it delivers heat, where equipment can go, how hot water is used and what electricity tariff behaviour you are comfortable with.

Check My Home

Could it heat my home?

Explore property type, heat loss, radiators and existing wet heating.

Could tariffs and solar help?

Understand time-of-use charging, peak top-ups and solar timing.

Do I need a cylinder?

Ask how hot water is delivered, stored and controlled.

What are the disadvantages?

See poor-fit signals, including limited space and tariff constraints.

Support and promotions

Check official support carefully.

Government support, product offers and installer finance are different things. The grants guide keeps those questions separate.

Before choosing a route, check the official scheme wording for the exact technology and installation—not a generic marketing headline.
