The ranges apply to a normal house. Actual cost depends on size, access and region. Lifespan means technical lifespan with normal upkeep.

Cost and detailIs the lifespan a guarantee?
No, the figures are common industry rules of thumb. Climate, workmanship and upkeep decide the real outcome. A tile roof that is looked after can outlast the range, and a roof that is never maintained may need replacing earlier.
Where do I find what a replacement costs?
The cost is on each group’s own page, alongside the typical lifespan and what to look for. Click the group you are curious about, for example roof or heating.
How is this different from running costs?
Running costs are what you pay continuously for power, heating, water and insurance. The lifespans here are maintenance that comes rarely but costs a lot when it does. As a rule of thumb, homeowners set aside about 1 percent of the home value per year for upkeep.
