A clear UK guide to new window prices
Unlike many home improvements, the cost of new windows is influenced more by specification than by dimensions. The same size opening can accommodate a £400 uPVC casement or a £2,000 timber sash, so the right choice for you depends on your priorities rather than what your neighbour paid.
These price bands reflect typical UK fitted ranges. Final pricing comes from the survey, where we factor in the exact spec, glazing, hardware and any structural work.
The 850 monthly UK searches for uPVC windows price reflect ongoing interest in the most affordable window material. uPVC accounts for around 80% of new UK window installations because it offers an excellent balance of cost, performance and durability.
Aluminium price points sit 50 to 80% above uPVC equivalents, reflecting the slim sightlines, larger pane capability and contemporary aesthetic that aluminium delivers.
Timber price points reflect the higher material cost, more complex manufacturing and authentic period appearance that suits listed buildings and conservation areas.
Most UK homeowners budget for new windows as a complete project rather than on a per-window basis:
The 3,300 monthly UK searches for window replacement cost reflect how often homeowners scope budgets at the project level before committing.

New windows in the UK usually cost around £400 to £2,000 per window fitted, depending on the frame material, window style, size, glazing specification, colour and installation requirements. uPVC casement windows are often at the lower end of the range, while aluminium, timber, sash, bay, tilt and turn and flush casement windows usually cost more.
A full house of new windows can vary widely in price depending on the number of windows, property type, frame material and glazing specification. As a guide, a standard three or four-bedroom home with several replacement windows may cost from around £6,000 to £20,000 fitted, with uPVC usually costing less than aluminium or timber. Period properties, sash windows and complex bay windows can increase the total cost.
uPVC window prices depend on the style and specification. 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, uPVC flush casement windows around £500 to £900, and uPVC bay windows around £1,800 to £3,500 for the full bay assembly.
Aluminium window prices vary by style, size, glazing and colour. As a guide, fitted aluminium casement windows often cost around £700 to £1,200 per window, aluminium tilt and turn windows around £1,000 to £1,800, aluminium sash windows around £1,200 to £2,000, and aluminium bay windows around £3,000 to £5,500 for the full bay assembly.
Timber window prices are usually higher than uPVC and aluminium because of the material, manufacturing process and traditional appearance. As a guide, fitted timber casement windows often cost around £900 to £1,800 per window, timber sash windows around £1,400 to £2,800, and timber bay windows around £4,000 to £7,500 for the full bay assembly. Timber is often chosen for period homes, listed buildings and conservation areas.
Single window replacement usually costs around £400 to £2,000 fitted, depending on the frame material, window style, size, glass type and installation details. Replacing one window can sometimes work out more expensive per window than a larger project because survey, travel and installation setup costs are spread across fewer units.
Two similar-looking windows can have different prices because the specification behind them may be different. Frame material, glazing type, energy performance, security hardware, colour finish, opening style, handle choice, trickle vents, trims and the amount of site preparation can all affect the final cost.
Supply only is usually cheaper upfront because it covers the windows themselves without installation. Supply and fit costs more because it can include measuring, installation, sealing, trims, making good, waste removal and project paperwork. Many homeowners choose supply and fit because it gives one point of responsibility for the product and installation.
Yes. Homeefe offers quotes for new and replacement windows across Rushden, Northamptonshire and surrounding areas within our approximate 80 km service area. Your quote can include an itemised breakdown of window type, frame material, glazing specification, colour, hardware and installation details, so you can compare options before deciding.
Energy-efficient windows can be worth the extra cost if your current windows are old, draughty, single glazed or poorly performing. Modern double glazed or triple glazed windows with Low-E glass, effective seals and insulated frames can improve comfort and help reduce heat loss. The exact value depends on your home, heating system, energy use and the specification you choose.

Several factors determine which price band your project falls into:
Adding triple glazing, acoustic-laminated glass, custom colours and premium hardware can push a project into the next price band. That’s why we itemise each upgrade during the quotation stage, making it easy to see exactly what you’re paying for.
Style affects price as much as material does:
The most affordable window style across all materials. The simple side-hinged design uses less material and manufacturing time than other window types.
15 to 30% more than equivalent casement windows because of the more complex sliding mechanism and traditional detailing.
3 to 5 times the cost of a single window because of the multiple windows in the bay assembly plus the structural support work needed for the projecting frame.
10 to 25% more than equivalent casement windows because of the more complex dual-function hardware.
5 to 15% more than standard casement windows because of the more complex frame engineering needed to deliver the flush appearance.
Similar to bay window cost, with the curved profile sometimes adding 10 to 20% over angled bay equivalents.
Spec choices that improve energy performance:
Energy efficient upgrades typically pay back over the years through reduced heating bills. The upfront cost of energy-efficient windows is often recovered through lower heating bills over their lifespan.
Supply-only lowers the upfront spend, but you organise the survey, fitting and Building Regulations compliance separately. Best for trade installers and DIY projects.
Supply and fit gives you:
The FENSA certificate stays with the property and is often requested during conveyancing. Most homeowners choose supply and fit for the single point of responsibility.
