Hi Craig Ambiguous, How so? i would have thought per square metre is as close to objective as we are likely to get. 1 Link to comment Share on other sites More sharing options...

Absolutely. 1 minute ago, saveasteading said: With my Estimator's hat, I would want a full S and F price from a window installer. From your installer no, fitting only unless they are supply and i stall but the m2 price should be seperate. Link to comment Share on other sites More sharing options...
saveasteading Posted January 4, 2023 Share Posted January 4, 2023 Just now, craig said: the m2 price should be separate. Should? A main contractor needs a price to plug in early, and then can adjust when quotes come in. So I would use between £350/m2 for upvc and £550/m2 for ali, based on recent quotes, and it would be very close. That will be out of date. I will work out our recent ones at some stage.

craig Posted January 4, 2023 Share Posted January 4, 2023 Of course your looking at build cost but product cost per m2 and install cost for comparisons between suppliers, should be separate for a fair and direct comparison (with many caveats).

Thorfun Posted January 4, 2023 Share Posted January 4, 2023 5 hours ago, Post and beam said: about £700/square metre for double glazed'. Seems expensive to me. That’s around Internorm quote we had for triple glazing iirc. Maybe shop around with other suppliers? Link to comment Share on other sites More sharing options...

Maybe shop around with other suppliers? Thats sort of the reason i jumped into this thread. I saw numbers being mentioned here that appear to be at odds with what i have learned so far. I need a breakdown, itemised line by line of the elements that are lumped into my 'weathertight package' phase of my build. At the moment i have an opaque figure for the package as a whole. It might turn out to be great value but as of today i dont have enough info to determine this. 1 Link to comment Share on other sites More sharing options...
jayc89 Posted February 2, 2023 Share Posted February 2, 2023 I'm also seeing around £750/m2 for aluclad windows, across a couple of quotes, right now. Supply only. Is that typical these days? Should I be challenging and pushing back? Link to comment Share on other sites More sharing options...
renovator123 Posted December 4, 2023 Share Posted December 4, 2023 Some prices are specs... we went with Internorm and the quality is excellent, really noticed the difference and they haven't even finished installing so it's not close to air-tight. Velfac V200E we also looked at - prices similar to Internorm. specs: Internorm Retrofit Timber/Alu Argon filled triple glazing 48mm (4b/18/4b toughened/18Ar/4) HF410 windows, 0.71 W/m2K stated, calculations were 0.73 to 0.84Uw HF410 doors, 0.73 W/m2K stated Doors had to be custom due to height, with 1/3 triple glazed obscure, 2/3 timber-alu. 9 windows, total 7.96 sq m 3 doors, 4.85 sq m with unusually low height that was unavailable from all major sellers (Solidor do Tinidor but no other big firms do). Dec 2022 price £14,435 excl VAT £17,320 with VAT included Fitting was all thermally broken eg compreband to our solid stone walls (EWI is planned). Extras: * Removal of old, retrofit, * 2 thumb turns and split spindles on doors * Hirest weather resistant color * 1 window obscure glass + Full fitting including removal of old and scaffold brought up * Cat flap fitted in 1 door * Presumably a charge for overnight accommodation (2 people, 4 nights) and travel due to distance Final cost: £24,342 incl VAT - May 2023 (discount of about 5 or 10% at the time) (£17,320 excluding 20% VAT). Skip costs extra. Not a single supplier in our county was willing to quote for any EnerPHit standard spec from any manufacturer so travel/hotel bumped our costs. Green Building Store wouldn't do fitting for their windows and doors and neither would local tradespeople. Well worth it but we absolutely need a HVAC for condensation since extra insulating the loft. Cat has been sunbathing near a window ever since it got replaced and the heating is on noticeably less despite it not quite being finished yet. 1 Link to comment Share on other sites More sharing options...
renovator123 Posted December 5, 2023 Share Posted December 5, 2023 TL;DR: Internorm EnerPHit prices above Windows approx £700-1,000 each inc VAT, fitting, removal of old, larger windows would likely be cheaper per sq m. Internorm only do single panel windows (glazing bars are an option) and only tilt and turn. Doors were in excess of £5,000 inc VAT and fitting, with only the HF410 model able to made in the shallow height we needed for retrofit, and us having a custom design. With no porch or conservatory on the house, the doors have made an incredible difference. Door designer prices are online: https://uk.internorm.com/internorm-door-designer/ Thumb turns & split spindle were fitted after by installer included in price, which were Winkhaus - amazing for keyless emergency exit, and keyless locking from inside without risk of accidentally getting locked out. Trickle vents - England - current UK regs state trickle vents are needed, clearly not suitable for EnerPHit or Passivehaus - but this regulation has some exceptions including certain other ventilation methods. https://www.gov.uk/government/publications/ventilation-approved-document-f 1 Link to comment Share on other sites More sharing options...
haythorn_1 Posted April 11 Share Posted April 11 Starting the process of getting quotes from a few recommended suppliers. Just got my first one from the local distributor of Rationel and nearly fell off my chair. Worked out at £1997 per m2. Quote is for 38m2 mostly of windows with a few French doors all in formaplus triple glazed with glazing bars. I had requested the order be split in two as this is a refurb in stages, if I combine to one it drops by ~10%. Still seems way beyond what I would have expected for Rationel. Hopefully some of the others are more reasonable. 1 Link to comment Share on other sites More sharing options...
Kelvin Posted April 11 Share Posted April 11 (edited) Our 3G Alu clad Low E Nordan windows including a french door and a sliding door with all the others tilt and turn were £760/m2 fitted. Jan 2023 prices. They went up significantly March/April time apparently. Ours were supplied as part of the timber kit so there would have been the kit suppliers margin included in that.

haythorn_1 Posted April 11 Share Posted April 11 Thanks @Kelvin, useful. Thats more like the kind of price level I was expecting. Nordan are on my list. Link to comment Share on other sites More sharing options...
saveasteading Posted April 11 Share Posted April 11 1 hour ago, Kelvin said: £760/m2 fitted. We bought Nordan too and our joiner fitted them very easily and quickly. I think a bit more costly than Kelvin's. But they wouldn't do slanted tops (no explanation) or work within our arches, so we bought aluminium windows for them at about half the rate. Perfectly good, but not tactile and lovely. 1 Link to comment Share on other sites More sharing options...
Kelvin Posted April 11 Share Posted April 11 Nordan are less flexible than many others. It also all got a bit difficult with max sizes and weights too. Our sliding door was originally 5m with a 1m tilt and turn window. But Nordan and the installer had different opinions on whether that could be 3G as it was too heavy according to the installer although Nordan said they could do it. In the end we fitted a 3.6m sliding door and a 1.4m French door which was the better outcome for us as the French door is a proper usable door whereas the tilt and turn windows are windows that can open like a door but they aren’t really that practical for every day use and are likely to get damaged.

Trw144 Posted May 16 Share Posted May 16 For information, just had an Internorm quote back - as I quickly calculate it, roughly 130m2 (including front door, some additional exterior doors, and two large gable ends), came in at roughly £850m2 fitted. 2 Link to comment Share on other sites More sharing options...
haythorn_1 Posted May 16 Share Posted May 16 That seems reasonable compared to what I've been getting: Rationel - £1997 Per m2 fitted Nordan - £1100 per m2 supply only Nordvest - £1050 per m2 supply only Norsken - - £2400 per m2 fitted I'm ordered far less glass (~40m2), have several bay windows and lots of glazing bars. This is also just the initial quote with no negotiation, but it's still way more than I was expecting. I've started looking at the top end of uPVC as an alternative. 1 Link to comment Share on other sites More sharing options...

Maybe shop around with other suppliers? We had an Internorm quote and they gave us 25% discount of the price. Our next door neighbour got 43%!! Never found out why. Ended up going with Idealcombi PH rated at about £400/m2 bought mid 2020. 2 Link to comment Share on other sites More sharing options...
Dunc Posted May 16 Share Posted May 16 I was going to suggest @Trw144 price may reflect the power of bulk buying? but then @haythorn_1 is buying 2x my area and looks to be more expensive. It likely depends on how many non-windows (lift& slde/paito/entry doors) there are. My internorm quote (April 2024) for 22.4m2 (1 lift& slide, 1 front door, all else T&T) was £939/m2 + fitting + VAT! At least delivery is included in that price 😕 GBS and Zyle are coming in at about £800/m2. Rationel, NordVest and others looking a little more sensible at <£700/m2 (+ fitting + VAT) but it's all rather eye-watering. Performance wise, GBS, Zyle and Internorm have average Uw values around 0.75 W/m2K for my window list. That drops to 0.85-0.89 for the less expensive ones. So for a 0.1 W/m2K hit in Uw at a peak difference of 30K (-10 C out/20C in) over the area (22.4 m2) that's only 67 W difference ....is that about right? If so, I'm not seeing how I'm ever going to realise the benefit of the extra investment up front. Have I missed something here? 1 Link to comment Share on other sites More sharing options...
peekay Posted May 16 Share Posted May 16 We have recently placed an order for just over 50m2 of Velfac doors and windows, that comes in at about £860/m2 including VAT at 5%, delivery and install. 1 Link to comment Share on other sites More sharing options...
haythorn_1 Posted May 16 Share Posted May 16 @Dunc I think you are right as I have two patio style doors but from looking at the individual windows they still seem very high. I want a traditional style but with modern thermal characteristics. So one of the larger windows is quoted like the below with multiple individual sashes and glazing bars. This window is £4k fitted from rationel. Supply only from nordvest for this was circa £3k. Maybe it's the style I'm asking for thats bumping up the cost? 1 Link to comment Share on other sites More sharing options...
