Meter performed during Winter

I have moved smart Meter during Nov 2018 and then changed the supplied fro SSE to Bulb. Unfortunately, Bulb doesn’t support smart yet and hence have to provide reading manually. However, this was useful for me toe track the meter behaviour.

Last year during 21 December 2017 to 16 February 2018 no of units records for dumb gas meter was 169 units
While this year, between 28 Dec 18 - 25 Feb 19 its (561 - 1024) = 463 units

Please note, there were redecoration works at the site during 21 December 2017 to 16 February 2018, heating was on 24/7. But between 21 December 2017 to 16 February 2018 heating was smart with hive fitted, yet I have to pay for 463 units.
