Our house is a Victorian villa with orginal single glazed sash and case windows. High ceilings so obviosuly correspondingly large windows.

Does anyone have a ballpark figure of where the cost of replacement sash and cash UPVC double/triple glazing would be? I'm sceptical of these "now 40% off" from specialist companies that have no pricelist and you're therefore at the mercy of a sharp salesmen pushing up "retail" just to make it look good.

For a guide, we have 7 large windows (about 2m high) - 3 in front room bay, 3 in the bedrooms, 1 in kitchen and bedroom then two smaller more "normal" sized ones ones in bathroom and kitchen. So 9 in total. Depnding on price I'd consider a new back door also but this is a non-standard size door.
 
It will depend on where you are geographically, and what spec you want the windows.
If the windows are as large as I imagine even considering you’re looking at upvc (the wrong choice in my opinion) I wouldn’t expect much if any change from 15k.
If you start talking about xenon filled triple or quadruple glazing you’re in for a hell of a lot more.
 
House over the road (1890 Victorian terrace) changed from period sash to cheap UPVC. Not only did it cost a fair amount the house lost value. Lost its character on a street filled with it.

If you can at least, get the triple glazed sash and don't change the style like they have.

Roughly speaking the large windows are 2m x 1m as I just bought a blind for one of them. Small are half that.

UPVC - this isn't our "forever" home. We're never going to recoup the outlay so going down the route of new wood sash and case with double glazing is a non-starter given the price. Warm and no draughts I'll pay for though.

Pretty sure from talking to previous neighbours in town that reconditioning existing sash and case costs about the same as buying new double glazing so all I'd be gaining is less draughts unless I upgraded to double glazed sash and case at the same time - more expense again but a possiblity depending on cost.

Roughly 50% of the street already has replacement double glazing - sounds like the one you're talking about just got the cheap stuff with thick frames, which I agree looks awful. It's not going to significantly change the house value as it's a desirable area.
 
Check if you’re in a conservation area (a lot of Edinburgh is). If you are then UPVC won’t be allowed and you will have to make do with sash (new or refurb).

House opposite me tried to replace the sash windows with UPVC and the Council took him to court and won and got an order to go in and reinstall wood sash - all at great cost to the homeowner!
 
As above, we're not in a restricted area - most of the street is already changed to sash style UPVC replacements

Got some indicative costs for refurb of existing sash and case plus upgrade to double glazed units which come out at about £1250+VAT per big window. Not actually as much as I was expecting I have to admit.

Probably going double not triple - doing some reading you lose a lot of solar gain through triple which on the large windows is worth having given the way they face.
 
I did a lot of research in to windows when building my house and i decided in double rather than triple for the solar gain reasons.

I remember thinking windows were a lot cheaper than i expected but most of mine are fairly standard sizes but i do have several full height windows and strange shapes like triangles. Think i had roughly 16 windows for about 7 or 8k, i wasn't paying VAT being a new build but i was surprised how cheap UPVC windows are.

Be careful with that assumption, there's not much of edinburgh which isn't in a conservation area, whether or not the neighbours have got planning permission the street.
Decent timber sash and case will be an advantage when you go to sell. If you do go pvc, get timber finishes internally (cill etc), pvc looks gash in older properties.

Upgraded windows will definitely look better but won't perform as well as pvc - and you wouldn't get triple glazed panels in them.

Just get a few quotes from local companies to compare, be very clear that you want their best and only price.
 
Crud plastic windows £150 - 200 sqm
Decent plastic windows £250 - 350 sqm
Composite or aluminium £450 - 550 sqm
Curtain walling £600+ sqm

I found it cheaper to get the original sash boxes re-made with double glazed panels, refitted with draft proofing and rehung on new lead weights and pulleys for less than UPVC

2 large tripe bays (220cm high glazing!) and a side window for (so 7 windowns in total) £5500
only the middle widow in either bay opens to keep the cost down

As its a significant outlay and you may not recoup the money, if you're not there for a long period is it not better to pay for more heating (ie not replace windows?)
 
Well that's sort of what I want to judge. No I'm not going to make the cost back but if it's reasonable then I'll take that over the period we're here as it will make the place nicer to live (it's pretty draughty) and look better on resale.

If I can find a cheaper company to refurb existing with double glazing then that looks like the way to go - I'd be happy with £1k/window for the large ones.
