Why Window & Door Prices Are Rising in 2026 – And What UK Homeowners Should Know
Advice & Guidance
Overview
Rising oil and fuel costs are once again increasing manufacturing and production expenses across the home improvement sector. With further price rises expected, securing a quotation sooner rather than later could help avoid paying more for the same products later in the year.
The key points:
- Window and door prices are rising due to increasing raw material costs, higher energy prices, and disruption to global supply chains.
- Supply chains are under pressure
- Energy-efficient windows can improve comfort, reduce heat loss, and help lower running costs.
- Upgrading windows and doors now can help offset rising living costs

How Global Events Are Impacting PVCu and Window Costs
Recent geopolitical tensions involving the US, Israel and Iran are already affecting global supply chains. While this may seem distant, it directly impacts the cost of manufacturing PVCu windows and doors in the UK.
PVCu is derived from petrochemicals, meaning production costs are closely tied to oil and gas markets. As these markets become volatile, manufacturers face:
- Increased raw material costs
- Higher energy prices
- Shipping and logistics disruption
Industry sources are already reporting upward pressure on pricing, as highlighted in this article:

What This Means for Double Glazing Prices in the UK
For homeowners, the outcome is straightforward:
- Manufacturers are paying more
- Suppliers are increasing prices
- Installers will inevitably follow
We are already seeing:
- Supplier price rise notifications
- Pressure on stock availability
- Longer lead times on certain materials
This mirrors previous industry cycles, particularly during 2020–2022.
Why Now May Be the Best Time to Secure Your Price
While no one can predict exact timelines, the trend is clear – costs are moving upwards.
Ordering now allows you to:
- Lock in current pricing
- Avoid future increases
- Secure installation slots ahead of demand
Many homeowners are choosing to move forward now to avoid paying more later for the same products.

Frequently Asked Questions About Window & Door Price Increases in 2026
Window and door prices are rising due to increasing raw material costs, higher energy prices, and disruption to global supply chains. PVCu is made from petrochemicals, so when oil and gas markets are affected by global events, manufacturing costs increase across the industry.
There is already upward pressure on PVCu pricing, with suppliers and manufacturers seeing increased costs in materials, transport and energy. This means prices later in the year are likely to be higher than current quotations.
For many homeowners, ordering sooner can help secure current pricing before further increases take effect. It can also help secure installation slots ahead of rising demand and potential supply delays.
Yes. Modern energy-efficient windows and doors will reduce heat loss and help keep warm air inside your home. This can lower the demand on your heating system and improve comfort, particularly during colder months.
Our industry-leading 28mm triple-sealed units achieve U-values as low as 0.8 W/m²K, helping to dramatically reduce heat loss and energy bills whilst improving comfort all year round. Even though they are only slightly heavier than standard double glazing with their unique 1.1mm internal pane, they deliver similar thermal performance to traditional triple glazing—without the added strain on hinges, frames and hardware, ensuring smooth operation and long-term reliability.
EcoMax Sun Secure glass combines strong thermal performance with laminated security glass. It offers a U-value of 1.0 W/m²K, helps reduce solar heat gain, provides UV protection to reduce fading, and adds an extra layer of security.
We are working closely with suppliers, managing stock carefully, and doing everything we can to minimise the impact of rising costs. Our focus is on maintaining high-quality products and offering clear, transparent pricing.
Energy-efficient windows can improve comfort, reduce heat loss, and help lower running costs. They can also make your property more attractive to future buyers thanks to improved energy performance.
