Aga vs Conventional Cooker Cost Comparison Calculator (Over 10+ Years)

By the Hill & May team

Updated 2026

An Aga can cost five figures to buy and a conventional range cooker a fraction of that, but the gap narrows or widens once you add years of running cost and servicing. Set how long you plan to keep the cooker and this tool shows the true total cost of each.

Cooker A: the Aga / heat-storage

Purchase price (£) Running cost per week (£) Servicing per year (£)

Electric Agas need no servicing; gas around £175, oil around £350.

Cooker B: conventional range cooker

Purchase price (£) Running cost per week (£) Servicing per year (£)

Most conventional cookers need no scheduled servicing.

How many years will you keep it?

A range cooker often lasts decades, so 10 to 15 years is a realistic horizon.

This compares cash spent, not resale value or the warmth an always-on cooker adds to a room. If a heat-storage cooker noticeably cuts your central heating in a cold kitchen, the real-world gap is smaller than the figures here suggest.
