New cooker, who do I call to connect the gas?

Interesting question. Going back a few years oil was more expensive than other forms of heating. But your question made me think, I know my mother-in-law’s all electric heating cost more than we paid last winter. I had a Google and this article sums up what has happened in the last few years. https://www.paulbraybrooke.com/running-costs-oil-gas-electric-heat-pumps/#:~:text=Given%20the%20price%20we%20paid,per%20kWh%20for%20gas%20heating. It is interesting also that he discusses heat pumps. We have looked at these and have never been able to make the math work for us, and the need to super insulate the house has been a barrier. Our house was fully renovated and insulated 13 years ago and we would still need to do more if we got a heat pump!
