Thanks so much for all the feedback! Lots of good suggestions for things I can tweak and improve. I'm at work currently so can't access my file, but I'll get the changes made later.
One thing I thought of, is it worth mentioning that the garden faces South-West? So it gets loads of sun, especially in the afternoon/evening. Or will people figure that out for themselves?
In addition, I shall additionally remove the additional additional. 
I'm not entirely sure why we have two boilers... They were like that when we moved in and are still going strong so we haven't felt the need to change them! The plumber assures us it's fairly normal in the area. And it's handy because you never lose hot water and central heating at the same time! 
There's a gas fire at the top of the stairs too that we were a bit
when we moved in, as apparently the previous residents put it there for the dog. However we've maintained it and not had it removed as on the odd occasion there's a power cut, it's been invaluable at heating the upstairs of the house! So we're never left cold. 
I've not heard of them tweaking council tax bands on sales (and we're definitely going to be selling for less than we bought 7 years ago, boohoo!) but I'll stick in a 'currently' or something, just to cover myself if the council do start meddling.
Broadband speeds is mentioned underneath the map, where it indicates we're part of the Leeds SuperNode so have the potential to get their maximum broadband speed package. Do you think I need to move that somewhere more obvious?
I've never heard of needing to have a water meter fitted when you move in... In this area, Yorkshire Water try and bribe you to get one fitted by saying you'll pay whichever of the bills is cheaper - fixed rate or metered - for as long as you live in the house.
The moment you leave the house, the deal is off... So the next person that moves in is then stuck with metered water for all eternity as they can't get the meter removed once it's in situe.
That's why I'm hoping it's a selling point that we've never had one fitted! (Given the baths and laundry associated with small children...)
Is there anything else people can think of that they'd like to know about an older house? :) We have gas and electric certificates, but were going to have those out on display on the day for people to see, rather than just alluding to them.
