How Much Do Windows and Doors Cost in 2026?

A transparent breakdown of window and door replacement costs in the UK — covering materials, installation, and the factors that affect what you actually pay. ## Average Costs by Material (Supply and Fit) These prices reflect fully installed costs including VAT, removal of old frames, and making good. Based on a typical 3-bed semi-detached with 8–10 windows.

| Material | Per Window | Full House (8–10) | |---|---|---| | uPVC (A-rated) | £450–£700 | £4,000–£7,000 | | uPVC (premium brand) | £600–£900 | £5,500–£9,000 | | Aluminium | £800–£1,400 | £7,000–£14,000 | | Timber | £700–£1,200 | £6,000–£12,000 | | Composite | £900–£1,500 | £8,000–£15,000 | ## Door Costs | Type | Typical Cost (Installed) | |---|---| | uPVC front door | £800–£1,500 | | Composite front door | £1,200–£2,500 | | Aluminium front door | £2,000–£4,000 | | Bi-fold doors (3-panel) | £3,000–£5,500 | | Bi-fold doors (4-panel) | £4,500–£7,500 | | Sliding patio doors | £2,000–£4,500 | | French doors | £1,200–£2,500 | ## What Affects the Price?

**Size and quantity** — more windows mean better per-unit pricing. Volume-based buying power (as offered through EvoHome) often reduces the per-window cost by 10–20%. **Glazing specification** — triple glazing adds 15–25% over double. Specialist glass (acoustic, self-cleaning, solar control) adds further. **Colour and finish** — white uPVC is cheapest.

Woodgrain foils add 10–15%. Coloured aluminium is standard; RAL colour matching may add a premium. **Access** — scaffolding is typically £500–£1,500 for a full house. Upper-floor replacements on difficult elevations cost more. **Structural alterations** — enlarging openings, adding lintels, or converting windows to doors requires Building Regulations approval and structural work.

**Making good** — internal plastering, external rendering, and decoration after installation. Some quotes exclude this. ## What Should Be Included in a Quote? A comprehensive quote should include: - Supply and installation of frames and glass - Removal and disposal of old frames - All hardware (handles, locks, hinges) - Internal and external sealing - Trickle vents (mandatory under Building Regulations) - FENSA/CERTASS registration - Guarantee terms (typically 10 years on frames, 5 on glass units) ## How EvoHome Helps As an independent consultancy, EvoHome compares multiple vetted installers for your project.
