Window Prices

Window Prices vary wildly, and the most difficult part about window prices being inconsistent is the fact that so many different companies are offering different alternatives. That’s not just uPVC, Metal, and Timber windows. Even within uPVC window prices there’s a whole range of types and stiles. There’s just so much to understand that we’ve collated all the information into one place, and we’ve also created a huge and comprehensive spreadsheet of window prices from companies we work with.

There’s a huge range to understand, and you might not want to read about certain window prices so to make this process as easy as possible we’ve included a table of contents for your convenience:

How much do wooden windows cost?

Please note that our wooden windows prices and costs only compare custom made, totally bespoke joinery. Where windows are double glazed, we assume a high quality Pilkington unit that is double glazed using low-E glass and Argon filled that is not toughened or laminate safety glass. We will price for these as well as acoustic and standard obscured glass too.

This window glass achieves a u-Value of 1.5 W/m2K. Wooden window prices vary from as little as £400 for a softwood fixed casement with no openers supply only all the way up to £20,000 inc VAT for a wooden bay windows. It’s well worth knowing the prices before discussing with suppliers as well as gaining an overall picture of what you can expect from different styles and materials. All the prices quoted assume on site inspection and professional measure in the case of install. Where supply only window companies expect the installer capable of measuring as liability cannot be accepted for incorrect or inaccurate joinery. This is part of the additional cost in supply and fit wooden window prices.

Wooden casement window prices

Standard wooden casements range from £475 for single glazed softwood that’s 800mm wide by 1200mm tall. The price goes all the way up to £1650 for a 1200mm by 1200mm that’s triple glazed. Larger non standard sizes are significantly more expensive. As we cover in a wooden casement window case study, the price for a hardwood double glazed bay window is £17,000.

There are four main types of wooden casement windows:

  1. Side casement hung.
  2. Top casement hung, lower fixed.
  3. Side casement hung, side fixed or both sides hung.
  4. Side casement hung, top casement hung, with lower fixed.

Window Style

Don’t worry, I realise that doesn’t mean a lot to a homeowner trying to get to grips with the jargon so this diagram of each casement style will really help simply the technical terms.

We look at the variance between single, double, and triple glazing. It’s worth noting that as of January 2019 the additional cost for Acoustic glass on casements should be in the region of £150-£225 per m2 of glass. We also look closely at the cost of hardwood and softwood. We also breakdown the install costs and supply on wooden casement windows.

Looking closely at the price of supply and fit, it averages around £250-£300 more per window. If we consider this will also include an insurance backed, ten year guarantee as well as having the install certified to meet building part-L then it’s clear a fair amount of work goes in for the fitting costs.

Case study: New wooden casement bay window prices.

Casements that fall out of non standard sizing will vary considerably in cost. Below is an example of a casement one of our companies quoted on. In this instance the homeowner requested a softwood and hardwood option:

With ornate glazing bar this casement bay window averaged £12,000 inc VAT in softwood and £17,000 inc VAT in hardwood. Bare in mind replacing a casement bay window like this isn’t a straight forward job. DIYer beware! The roof must be supported as this wooden casement is load bearing. You can see from the thickness of the mullion. This adds an extra complication but will not be a problem for a professional wooden casement window installer.

New wooden casement bay window

The prices quoted did not include glass obscured to match the original pattern. The homeowner wanted more light and a better view outward. All detail including profiles and glazing bars to look as original as possible and the glass quoted was Argon filled, Pilkington low-E, toughened. This is a pretty high end spec.

Wooden sash window prices

Wooden sash window prices range from £800 for a pair of sashes installed into the original frame up to £8000 for a bay window with arched head. There are far more specifications and options on sash windows when compared to casements because of their cost and the development in technology within this market. There’s also far more options for example timber BC Pine might be required where a building is listed.

It’s very common that specialist sash window companies can offer double glazed sashes without the requirement for entire replacement. This saves considerable money, as much as 50% on complete replacement prices. We have a dozen reputable London suppliers within the prices noted to choose from.

It should be noted that sash window supply only normally involves the window being assembled on site. This means box frame, sashes, trims, and weights are supplied ready to build. For a professional it takes little more than thirty minutes to assemble a window but if you’re trying to save money it might be worth asking for a window that’s fully built that can simply be installed.

There are three main styles of sash windows:

  1. 1 over 1 sash windows.
  2. 6 over 6 sash windows(often referred to as Georgian sash). These might also be 4 over 4 or 8 over 8. The term Georgian loosely refers to sash with many glazing bar of equal size panes of glass.
  3. Curved head sash windows.

Here’s a diagram of each to make this clear:

three main styles of sash windows

The technical terms become pretty clear, the number over each simply means how many panes of glass in each sash. You can also have varying panes such as 3 over 1, or 6 over 2. Plenty of quirky styles were invented some hundred and thirty years ago. This is absolutely no problem at all because all sash windows are hand crafted using the same joining techniques employed back then too.

Fitting sash inside the original frame represents a significant saving over complete replacement. It should be noted that this method normally only carries a five year guarantee and is not insurance backed. Seeing as it is not a new install it does not involve itself with building part-L and therefore the install cannot be certified for u-Values. That said, we are well aware of the significant improvements in heat and acoustics that result from use of the original frame.

Case study: Double glazed sash windows installed into original frame

Double glazed sash windows installed into original frame

In this double glazed sash windows case study we look at the price of a new double glazed sash windows.

This bay and singe window are pretty standard and the spec on glazing is toughened, Argon filled, low-E Pilkington glazing with the sash made from hardwood. The windows come with factory spray finish. The single window was quoted as £1800 and the bay window £5200. These are pretty typical prices and the location was London. You might expect slightly cheaper outside of London given these are standard 1 over 1 sash windows.

The install came with a Certass certificate to comply to building part-L and a ten year insurance backed guarantee. This means that for whatever reason if you’re installer closes, you’ll be protected and can have repairs effected within that period on the insure backed guarantee instead.

How much do acoustic glazed wooden windows cost?

Acoustic glazed wooden windows often cost £150-£225 per m2 of glass additional to standard double glazed costs on wooden casement windows. This assumes a 6.8mm acoustic laminate upgrade.

Wooden sash windows will attract a considerably higher cost. This is because the weight of the glass must be counterbalanced as well. Acoustic laminate weighs 17kg per m2 and the cost of lead is around £3.50 per kg. This raises the costs of acoustic laminate on wooden sash windows to around £200-£275 per m2 more than standard double glazed sash windows.

How much do uPVC windows cost?

uPVC window prices are considerably lower than wooden windows. This is because material and manufacture cost is considerably lower. Normally uPVC windows will cost from as little as £250 supplied and fitted for basic double glazed glass and a base A rated white uPVC extrusion. You can pay as much as £4000 for a uPVC bay window with high spec glazing. Also, uPVC sash windows are normally a little more expensive but cost around 30-40% less than timber sash windows.

There are a few variables which will alter the pricing for example wood grain effect, locking mechanism, and glazing option.

There are four main types of uPVC casement that are sold as standard:

  1. Side hung up to 0.8m2 (typical 600mm by 1200mm max.)
  2. Top hung, lower fixed up to 0.8m2 (typical 600mm by 1200mm max.)
  3. Side hung, other half fixed up to 1.2 m2 (typical 1200mm by 1200mm max.)
  4. Side hung, other half top hung, with lower fixed (typical 1200mm by 1200mm max.)

Here’s a diagram showing each of these uPVC window styles:

Window Style

There are larger uPVC windows and some different styles but for price comparison purposes we will concentrate on these examples. The case study will look at uPVC bay windows and large uPVC windows. Our comparisons are based on Synergy profile with the new Yale blade locking system with its unique 12 year guarantee.

Case study: uPVC casement windows.

INSERT BAY WINDOWS AND SINGLE FROM CONVO WITH ROB

If we take a look at the casement in this picture, we can see that there is two, 5 window bays. There’s also a single double opener. The two bays the two bays will cost approximately £1200 to £1,500 each. The single window on it’s own will probably cost around £450 to £650.

This pricing assumes standard double glazed units with an A rated white UPVC casement plastic extrusion. If you would like to upgrade to Pilkington low emissivity glass then Factor and additional £300 to £400 on the prices provided. Additionally, if you’d like to have toughened glass then this will also increase the costs around about £300 to £400 as well.

In this example the client wish to have to upper casements functioning and to lower casements functioning per 5 window bay. This is a pretty typical arrangement and there’s not really any need to have all of the casement functioning.

In terms of fitting these windows will take a day to install and all trims and making good wood would almost certainly be finished. These windows were fitted with Yale high quality locking mechanism and carried a 10 year insurance.

uPVC Sash window prices

uPVC sash windows have improved considerably in the last ten years. Profiles are now thinner than ever, decorative mouldings are improving, and overall they are very efficient. There are some major benefits such as price, uPVC sash windows prices tend to be about 30-40% cheaper than traditional hardwood sash windows.

There are a few issues with uPVC sash windows. They are built on spiral balances which are prone to fail. This is fine with a ten year warranty but the cost of replacing spiral balances is quite significant and your installer may not be able to do it as it’s a skilled job.

They don’t look at good as traditional sash, but when factoring the price, it’s well worth weighing up the options. I would go for traditional hardwood sash because most homes in London are extremely expensive and it’s well-known that class uPVC windows can actually reduce the value of your property there for the money you save uninstall might end up being lost on the sale.

This doesn’t stand true for all houses and properties however many 1920s homes in London that were built with a casement arrangement will of course look better with timber but it’s certainly accepted that plastic casement would be more than good enough and certainly wouldn’t be something that was flagged on a home survey.

So bear that in mind when you purchase UPVC sash windows over traditional hardwood sash windows.

Case study: uPVC sash window prices

In this UPVC sash window prices casement study we take the look at a 3 bay window glazing bar the glass selected was Pilkington low-emissivity glass with an argon filled unit.

This particular variation of you of you of a UPVC sash window is tilt and turn. That means that if your building is tall and your windows are high up you can turn them in words and clean the glass from the Inside without reaching.

As you can see from the picture it doesn’t look bad. They are just a little bit thicker than traditional original, elegant sliding sash windows but overall they’re very secure and efficient.

INSERT PICTURE OF BAY UPVC HERE

It’s also impossible to replicate the original horn style. This is the small detail underneath the top sash with a curve.

Overall for the price they’re pretty good value for money, be aware that if you were in a traditional Victorian home it might not be the best solution when considering resale of your home.

This type of uPVC sash window typically costs anywhere between £850 to £1,200 power window assuming that it’s a 1000mm wide by 1800mm high. So across the whole Bay it’s pretty reasonable to expect to pay anywhere between £2,900 and £3600 in total.

With UPVC sash window prices being around 30% to 40% cheaper than traditional sash windows, they are well worth considering.

This particular install comes with a 10 year insurance and the glazing will be a high quality polyurethane. It’s very likely that the class will last more than 20 years. Assuming there’s no issues with the spiral balances and counter and mechanism, then these will make an extremely efficient low-maintenance sash window for many years to come.

How much do Aluminium windows cost

Aluminium window prices are typically more than UPVC windows but very similar to wooden and timber sash windows. Aluminium windows look far more attractive than UPVC windows but still not quite as good as traditional sash.

Metal Windows typically cost from around £800 all the way up to £3,000 per window. They offer the best durability because they’re powder coated aluminium doesn’t Decay anywhere near as quickly as timber or UPVC.

With that said they do have some major benefits. They have tight sight lines at just 42 mm. This is the same thickness as a traditional sash Rail. They also attempt to replicate an authentic chamfered sash profile of course it’s not as good as a Ovolo from the Victorian period but it still looks nice.

They’ve also worked out how to make the lower rail with 95 mm which is the same depth as a traditional lower sash rail which From a Distance gives a pretty authentic look.

Giving their construction they operate on spiral balances, these are the same as UPVC sliding sash windows. Typically these windows are energy ‘B’ rated and conforming to part L of the building regulations.

It’s pretty normal that the until in words for easy cleaning and this is a real bonus if your home is in a block or the windows are up. Overall aluminium window prices are pretty reasonable and they’re strongly durable.

It’s becoming quite fashionable to have a graphite grey on the outside. There are very modern and art architecturally sound invention. We’re going to take a closer look aluminium window prices.

Case study: aluminium windows prices

In this example we take a look at two aluminium windows. This is a pair of typical sash windows with an opening of around 1000mm wide by 1800mm high.

These windows are finished with her graphite grey powder coat paint and come with a manufacturer’s guarantee of 15 years. They are operating on sliding spiral balances that have the ability to tilt and turn.

These windows cost the homeowner £3,400 including VAT. This includes a 10 years manufacturer’s insurance backed warranty. The windows come with uprated Yale locks and I designed with a high quality seal for maximum performance.

Notice the styles and sight lines are quite slender and with the bottom rail being 95 mm as per one of the options with these windows they look visually quite appealing.

If these are normal aluminium windows that one sliding aluminium sash windows then it would be reasonable to think with these openings that the cost would be around about £2,000. What is good as sliding sash and they also don’t function in the same way but if you’re on a budget they do look ok and they are very durable. That it might be a legal to replace your windows with the sash windows and you should always check with the planning/conservation officer first.

Summary of window prices

When considering new windows for your home it’s important that you carefully research the benefits and negatives of all different window types. Sash windows made and constructed of hardwood are typically the most expensive but then off for the most benefit in terms of Aesthetics and value added.

That said, uPVC casement windows look fine in a more modern building and cost a fraction of the price as well as being equal if not better in performance.

Aluminium windows look better than uPVC windows but it’s hard to know if the cost is justifiable. Pretty good in a more modern home. Which traditional sliding timber sash windows looking so wonderful, it’s also hard to justify the cost of sliding aluminium sash windows even the prices are not too dissimilar. But would that said if you’re high up and need a solution to clean your windows and you’re looking for a window that will be maintenance free for decades to come an aluminium is the window of choice, so there’s no one windows fits all cases scenario.

So it’s important to research exactly what’s going to benefit your property the most. Normally asked their neighbours and take a look at what others have done down the roads as a bit of a guideline as to the best way to proceed.
