I’ve heard from tradespeople that say the electricity does go through the roof in winter for those air to heat pumps, of course basset’s are going to dismiss this. Wait til you see in a year or 2 time, Caroline will be yapping about the bill, when the collaboration is over
Watch this space … when that time comes

and she thinks people have forgotten all the rest of the free house stuff she has been given and the payment for all the build partner advertising she will be starting on her next ‘build partner’ project
Free solar panels, and install and a fee to promote them
Can imagine she will want to reap as much as she can now of pure build cost like heating systems
At least one bathroom fitted out
Then next up a kitchen
Then it will be appliances - maybe even two ovens and a built in microwave (as she has no room for one in current kitchen)
Then it will be furniture beds sofas tables and the like
Then interior design and curtains
Maybe some pictures mirrors and a media wall
Then bedroom furniture like wardrobes etc
Then maybe landscaping or a garden room
Then solar panels
I bet she has a long list of places she can fleece and money she can also make in the process
