uPVC windows are the most popular window material in the UK and account for around 80% of new window installations across the country. The combination of good thermal performance, multi-point security, decades of low-maintenance service life and affordable pricing puts replacement windows ahead of aluminium and timber alternatives for most family homes.
We supply and fit uPVC windows in Northamptonshire within an 80 km radius near Northampton, with the full range of uPVC casement, sash, bay, tilt and turn and flush casement windows available in the full RAL colour palette plus authentic wood-grain foil finishes.
uPVC windows are window frames manufactured from extruded unplasticised polyvinyl chloride profiles. The “U” in uPVC stands for unplasticised, which is what makes the material structurally suitable for window frames rather than the softer PVC used in pipes and flexible products.
Modern window systems use multi-chamber profiles with internal steel or aluminium reinforcement at the locking points. The multiple chambers reduce heat transfer through the frame, while the reinforcement gives the window the structural strength needed for multi-point locking and reliable long-term operation.
These windows are built on VEKA profiles, with Profile22 and Deceuninck systems available depending on the specific style and configuration. These are some of the established European uPVC profile systems, engineered for British weather and current UK Building Regulations.
Several key advantages have established uPVC as the most widely specified window frame material in the UK.
Modern uPVC windows achieve U-values from 1.4 W/m²K with double glazing and 0.8 W/m²K with triple glazing. The multi-chamber profiles reduce heat transfer through the frame, while the multi-point locking compresses the sash against perimeter seals to minimise air infiltration.
For typical UK homes replacing older windows with modern uPVC double glazed alternatives, the heating bill saving usually shows up in the first winter after installation. The reduction in draughts around window perimeters is often the most-noticed practical change.
uPVC windows need virtually no maintenance beyond an occasional wipe with soapy water. They don’t warp, split, rot or need painting like timber windows. They don’t corrode like older steel windows. They don’t need re-treatment or oiling on exposed elevations.
A well-fitted uPVC window typically lasts 25 years or more without significant maintenance work. The hinges and locking hardware may need occasional adjustment, but the frame and glazing units stay functional for decades.
uPVC is naturally weather-resistant. The material doesn’t degrade significantly under UV exposure, doesn’t absorb moisture, doesn’t suffer from frost damage, and handles temperature changes without warping or cracking. Modern uPVC windows in UK weather conditions typically outlast their sealed glass units (which fail at 15-25 years) by another decade or more.
uPVC windows cost significantly less than aluminium or timber alternatives. Standard uPVC casement windows typically cost £400 to £800 per window fitted, compared with £700 to £1,200 for aluminium and £900 to £1,800 for timber. The price advantage matters for full-house window replacement projects where the total project cost runs into the thousands.
Every uPVC window we supply includes multi-point hook locking as standard, with the locks engaging at multiple points around the frame perimeter. Combined with internally-beaded glazing (preventing the glass being removed from outside) and TS 007 cylinders, modern window system deliver security significantly better than older windows.

uPVC windows are window frames made from unplasticised polyvinyl chloride, a durable and weather-resistant material commonly used for replacement windows in the UK. uPVC is popular because it is low maintenance, naturally insulating and suitable for many window styles, including casement windows, sash windows, bay windows, tilt and turn windows and flush casement windows.
uPVC window prices depend on the window style, size, glazing specification, colour and installation requirements. As a guide, fitted uPVC casement windows often cost around £400 to £800 per window, uPVC sash windows around £600 to £1,200, uPVC tilt and turn windows around £600 to £1,000, and uPVC bay windows around £1,800 to £3,500 for the full bay assembly.

When fitted with Low-E glass and warm edge spacer bars, uPVC windows can help reduce draughts, improve comfort and limit heat loss through the window area.
Yes. uPVC windows are low maintenance and usually only need occasional cleaning with warm soapy water to keep the frames looking fresh. Unlike timber windows, uPVC does not need regular painting or staining, and it is resistant to common issues such as rotting, splitting and warping.

The full RAL colour palette is available on modern window systems, plus authentic wood-grain foils that resemble genuine timber.
White uPVC windows remain the most popular choice in the UK because they suit most property types and provide a neutral appearance that compliments the building. The modern uPVC white doesn’t yellow significantly even when exposed to decades of UV exposure.
Anthracite grey uPVC windows have grown rapidly in popularity for both contemporary new builds and renovated period properties. The shade pairs well with red brick, render and most external materials. Anthracite grey leads UK colour preferences currently.
Black finishes make a contemporary statement, particularly on modern new builds and period properties wanting a striking contrast against light render or red brick. Available across all these window ranges.
Grey uPVC windows in shades from light grey through to darker charcoal and slate suit modern and traditional properties. The variety of shade options give flexibility allowing coordination with existing windows on neighbouring properties or other external materials.
The full RAL range oAers an extensive choice of colours. Chartwell green and traditional cream suit period properties. Heritage white, Brunswick green and Oxford blue suit Victorian and Edwardian properties. Custom RAL colours are available for properties desiring a specific shade match.
Wood-grain foils give the appearance of timber without the maintenance demands of real wood. Golden oak, Irish oak and rosewood are the most popular heritage finishes, suitable for cottages, period properties and any home wanting timber character with uPVC practicality.
Dual-colour finishes give you one colour outside (matching the front elevation) and a different colour inside (matching the room scheme). White inside with anthracite grey outside is the most popular dual-colour configuration on modern UK properties.
uPVC windows prices vary by window style, size, glazing spec and colour.
Standard uPVC casement windows typically cost £400 to £800 per window fitted. uPVC sash windows cost £600 to £1,200 per window. uPVC bay windows cost £1,800 to £3,500 for the complete bay assembly. uPVC tilt and turn windows cost £600 to £1,000 per window. uPVC flush casement windows cost £500 to £900 per window.
Premium colours (coloured RAL, wood-grain foils, dual-colour finishes) add 10 to 20% over standard white pricing. Triple glazing adds 20 to 30% to the standard double glazing price. Acoustic-laminated glass and Secured by Design upgrades are also available at an additional cost.
For homeowners replacing uPVC doors and windows at the same time, combined packages typically deliver 10 to 15% savings. Many homeowners compare uPVC window prices before booking a survey, because the final cost depends on window size, style, glazing specification and finish.
