How Much Does a Whole House of Windows Cost in Liverpool in 2025?

When it comes to home improvements, replacing your windows can have a significant impact, not just on aesthetics, but also on energy efficiency, security, and overall comfort. If you’re considering upgrading all the windows in your Liverpool home in 2025, you’re probably wondering how much a set of new windows costs. At JWS, we understand this is an important investment, which is why we want to guide you through the typical costs, styles, and factors that influence prices so you can make an informed decision.

Why Replace All the Windows at Once?

Replacing all windows at once may seem like a big job, but it’s often the most efficient route for homeowners who want a consistent look, better energy efficiency, and to stop draughts across the whole property. From reducing your energy bills to improving security and even increasing your home’s kerb appeal and market value, new windows are a smart home improvement.

What Affects the Cost of New Windows?

The price of new windows depends on several key factors:

• Type of window: Different styles range widely in price.
• Materials: uPVC, aluminium, or a combination.
• Size and number of windows: Larger or more numerous windows add up.
• Glazing options: Double, triple glazing or specialised coatings.
• Installation complexity: Older properties or awkward fittings may require more work.
• Energy performance: Premium energy-efficient windows can cost more upfront but save you money in the long run.

The Average Cost of New Windows in Liverpool:

Here’s a rough guide to the types of windows Liverpool homeowners typically select, along with average cost ranges per window, supplied by Check-A-Trade.

Below, you’ll find a general budget overview for your installation.

Window Style & Frame Materials

Casement windows are the most popular and widely used window style across the UK, particularly in Liverpool. Hinged at the side and opening outward, they are valued for their versatility, excellent ventilation, and cost-effectiveness. Typically available in various styles, casement windows are straightforward to install thanks to their simple design. Prices generally range from £700 to £1,100 per window, with uPVC models on the lower end and aluminium options commanding higher prices. In Liverpool, they remain the most affordable and commonly installed window type.

Sash windows are a classic choice, particularly suited for period properties and listed buildings, thanks to their traditional charm and vertically sliding design. They often require timber frames and specialist joinery to maintain authenticity, which contributes to their higher cost. In some cases, planning permission may also be necessary. Due to their more intricate construction and the use of traditional materials, prices for sash windows typically range from £1,350-£1,850 per window. Modern versions featuring double or triple glazing can further increase the overall cost.

Bay and bow windows are ideal for homeowners looking to add character, space, and natural light to a room. These window styles extend outward from the wall, creating a small interior alcove that enhances both aesthetics and functionality. Due to their larger size, multiple panels, and the structural work often required, bay and bow windows are more complex and costly to install, sometimes costing twice as much as standard casement windows. 

Tilt and turn windows are a popular choice in modern and contemporary properties, offering a sleek design and flexible functionality. These windows can open in two ways, tilting inwards for gentle ventilation or swinging open like a door for full airflow and easy cleaning. Often framed in aluminium for a modern aesthetic, tilt and turn windows tend to be more expensive than standard options due to their advanced hardware and more complex opening mechanisms. 

According to Check-A-Trade, the cost for a whole house of new windows falls between £8,000 – £15,000; however, if you want an accurate estimate customised to your home, then use our online quoting engine today!

Window frame choices not only affect your home’s look but also the installation price and maintenance needs. uPVC windows are by far the most popular in Liverpool, thanks to their affordability and low maintenance. uPVC frames are generally the most cost-effective, generally ranging from £500 to £1,100 per window.

Alternatively, our aluminium frames are increasing in popularity due to their sleek, modern appearance and durability. Aluminium windows tend to sit in a mid to upper price bracket, roughly £700 to £1,300 per unit.

The Impact of Glazing Options:

The type of glass chosen plays a significant role in both the cost and performance of windows. Double glazing is the most common option, providing excellent energy efficiency and noise reduction at a reasonable price. At JWS, all our windows are supplied with double glazing as standard, helping to minimise heat loss and external noise effectively. On the other hand, triple glazing is a premium choice in 2025, offering superior insulation and soundproofing. Although it can increase the upfront cost by 20-30%, triple glazing is a worthwhile investment for homes near busy roads or those needing enhanced thermal performance.

Additional Costs to Consider:

For a whole-house replacement, scaffolding is often required, especially for two-storey properties or those with awkward access. Scaffolding typically adds £350 per elevation, alongside labour costs on top.

If your existing frames need removal, or if repairs to the surrounds or walls are necessary, these costs could increase.
