Running Costs

Each household will use their converted Aga differently so it is hard to estimate costs of usage.

However, based on 2 working adults using a converted 2 oven Aga over 12 months, using it efficiently (i.e. only running the Aga when required) the average daily running cost was found to be less than a £1 per day. The electric unit cost of 15p including vat was used in this calculation.*

The converted Aga was used as follows:


AUTUMN 3 months
timed operation on times 06:00 – 09:00 / 16.00 – 21.30 – 454Kw used

WINTER 3 months
with oven on 24 hours a day – 708Kw used

SPRING 3 months
timed operation on times 06.00 – 09.00 / 16:00 – 21.30 – 615Kw used

SUMMER 2012 3 months
switched on when needed for cooking – 287Kw used

The hobs were used only when required, this gave a total annual usage of 2064KW used.

At a rate of 15p* per KW this equated to £310.

Cost to Convert your Aga to electric Conversion

We will undertake a site survey either by visiting your premises or by receiving photos.  We will then be able to provide an estimate of costs.

Currently our 2 oven Aga clients will expect to see a 2 ½ year payback if used to its maximum benefits e.g. as per 2011 data above.

The conversion works in such a flexible way, unlike any other conversion or alternately fuelled range, that it cannot really be compared like for like. If you did run the conversion at manufacturers recommended temperatures it would still work out far cheaper to operate.

*the price of electricity does vary and the figures are based on average prices at the time of running the experiments
