Looked up the EPC of the place I'm buying, it has granite walls. 31 sq m floor area, the estimate for heating cost is £1100 a year with gas central heating.
By comparison the brick terraces I'm selling are 59 sq m with estimated heating cost £650 a year, again with gas.
The figures for all the houses assume no loft insulation.
So, the suggestion is that houses with granite walls need over 3 times as much energy to heat the rooms compared to houses built with brick.
I'm not having it, think it's bollox.
Any opinions?

No doubt lovely and cool in summer.
You win some ...

I lived on a granite house when I was very little. In Pembrokeshire. 2-5 years old.
Granite is radioactive and does something to people's brains.

Northamptonshire stone houses stay warm once heated, this house is our first thermalite block/ cavity insulated/rendered block house we have had and we feel that the old stone cottage in Northants was warmer in winter and cooler in summer.
Of course the above is only subjective but we don't have a solid fuel stove in this house.

One more thought, it does take a long time to get a stone house up to temperature from cold, 4deg, once its warmed up it stayed warm.

Basically, the thicker the walls, the less temperature fluctuation there will be. Think of the walls as storage heaters.

Horror House was the most expensive house to heat that I've ever owned.. Stone built, solid fuel..it devoured fuel. Warmed up but soon chilled again.

If you live in a house do people ask "is it cold in the winter?"?
As a boat dweller if I get asked this I usually say "Well yes, this is England and the climate means it usually does get quite cold in winter. Have you not been here in winter? The boat is perfectly warm due to having a heating appliance fitted".

Every stone house I have encountered was bloody cold in winter. But maybe if you can have solid fuel heating and it is a cast iron box in the room it might be alright. Trad fireplaces are crap. Otherwise a gas fire of some sort...
I imagine from what you said the rooms are small so that will help from a heating POV.

When we bought the cottage It had a old Parkray in the kitchen that devoured a 20kg bag of Phunicite a day in the winter. It was replaced with a Charnwood Country 6 that made a 20kg bag last 3 days. I was amazed how much difference a decent stove made

'Young' granites such as the 'Rapakivi' granites of southern Finland can still be 'warm' and produce radioactive radon gas. The government hands out money for protective flooring to help prevent this gas building up in large masses in buildings. Does Wales really have 'granite' for building? Probably diorite or gabbro or a migmatite or an anorthosite in Ricco's ex-fisherman's cottage?

Any opinions? do the terraced houses have cavity walls?
there is not much difference between brick and stone as materials, but an air gap in cavity walls makes a huge difference There are 3 modes of heat transfer - conduction, convection and radiation. Bear in mind that cavities contain still air - very little convection, no radiation (of heat - not radioactivity!!) and low conduction because the low density of air corresponds to low heat transmission (in or out). By the way, the only difference between still air and foam insulation in the cavity is that the foam guarantees the absence of any slight air movement.

One of the warmest houses I ever stayed in was a very old stone cottage in Cornwall. It had massive thick walls and providing you never let it get properly cold it wasn't hard to heat ...... but it had to be constant ...... let it get cold and it took ages and a ton of fuel
