Does anyone have a favorite rad sizing app or site? I've used a few but they seen to vary and many are quite clunky.
Any out there with decent accuracy, a whole house report would be amazing too...

Good old fashioned sheet from manufacturer. I tend to look at Stelrad sheets.
Print one off and leave it in the van.

I tried a few last year before replacing all my radiators and liked the Myson Heat Loss Manager best because it lists the heat loss from each room for each element: glazing, external wall, floor. roof glazing, roof, ventilation and heat-up factor.

Of course this needs some work to enter all the details but a calculation is only as good as the data input.

That sounds good, it could also help highlight where it might be worth spending money to improve heat retention.

IMO, 50mm is definitely worth increasing to 200mm. The benefits of changing from 200mm to 300mm are more marginal. I am not a fan of retrofitted...
