HR++ glass installation in Birmingham
Prices are valid for 2026 and are indicative
Here you can see what hr++ glass installation in Birmingham costs on average. We explain what the price consists of and which local factors have the biggest impact.
In the UK, double glazing costs £400–£1,200 per window depending on size, material (uPVC, aluminium, timber), and glazing specification (double or triple). A full house replacement (8–12 windows) typically runs £5,000–£12,000 for uPVC and £8,000–£20,000 for aluminium or timber frames.
All replacement windows must comply with Building Regulations (Part L) and be installed by a FENSA-registered or CERTASS-registered installer, or alternatively covered by a local authority building notice — otherwise you'll need Building Regulations approval separately.

Cost factors
Double glazing costs per window in the UK, including supply and installation (VAT at 20%).
- uPVC casement window (standard size): £400–£800
- uPVC sash window (Victorian/Edwardian style): £600–£1,200
- Aluminium window (standard size): £700–£1,400
- Timber window (standard size): £800–£2,000
- Full house (8–12 uPVC windows): £5,000–£12,000
- Full house (8–12 aluminium windows): £8,000–£20,000
Prices include FENSA registration and certificate. Triple glazing (recommended for north-facing and exposed elevations) adds 20–40% to costs but can reduce heating bills by a further 10–15%.
Why do prices vary?
- Frame material: uPVC is cheapest and most common. Aluminium offers a slimmer, more modern profile. Timber is traditional and required in many conservation areas but needs more maintenance.
- Window style: Casement windows are the simplest and cheapest. Sash windows (popular in Victorian and Edwardian homes) are more complex and expensive due to their sliding mechanism.
- Glass specification: Standard A-rated double glazing is the minimum for Building Regulations compliance. A++ or triple glazing is better for exposed or north-facing windows.
- Conservation areas and listed buildings: Conservation area or listed building restrictions may require timber frames, specific styles, or planning permission. Costs can be significantly higher.
- Number of windows: Full-house replacement offers economies of scale — per-window cost decreases for larger orders. Always get a total price, not just per-unit quotes.
- Removal and disposal of old windows: Most FENSA installers include removal and disposal in the price — confirm this before signing.
Subsidies & incentives
There is no dedicated double glazing grant in England. However, window upgrades may be funded as part of a broader retrofit package through the Warm Homes Local Grant. In Scotland, the Home Energy Scotland scheme offers interest-free loans of up to £15,000 for energy improvements, including windows. Wales's Nest scheme and Northern Ireland's Affordable Warmth scheme provide support for eligible households. VAT on double glazing is the standard 20% — it does not qualify for the 0% Energy Saving Materials rate.
Local considerations in Birmingham
Average (baseline)UK's second-largest city — diverse housing stock and competitive trade rates. Strong demand driven by growing population.
Housing characteristics in Birmingham
Birmingham is the UK's second city and has one of the most diverse housing stocks in England. Inner Birmingham (Moseley, Balsall Heath, Kings Heath) contains Victorian and Edwardian terraces comparable to those in Manchester and Leeds, often built as artisan housing for factory workers. The inter-war period produced a huge wave of semi-detached housing across Solihull, Sutton Coldfield, and the outer suburbs — the classic 1930s British semi, with cavity walls (now suitable for insulation), bay windows, and modest rear gardens. Post-war council estates in Erdington, Chelmsley Wood, and Northfield represent a significant portion of the housing stock. Birmingham's substantial South Asian community has driven a distinctive renovation culture, with particular demand for kitchen upgrades, extensions, and multi-generational living modifications. Trade rates are competitive — typically 10–20% below London — and the large construction workforce trained through the city's apprenticeship programmes keeps labour supply strong. The Legacy Development corridor from the 2022 Commonwealth Games has catalysed significant residential investment in east Birmingham. ECO4 uptake has been high in Birmingham given the city's significant proportion of lower-income households in older, poorly insulated housing.
- Mix of Victorian terraces, inter-war and post-war semi-detached
- Competitive trade rates — good value for renovation projects
- Large proportion of 1920s–1960s semi-detached housing in outer suburbs
- City-centre regeneration driving high-spec apartment conversions
- standard Building Regulations and planning requirements
- broad selection of local and regional contractors
- typical scheduling availability throughout the year
- FENSA or CERTASS registration required for Building Regulations compliance
- Standard 20% VAT applies to double glazing — no reduced rate
- Conservation area and listed building restrictions may require planning consent
- BFRC energy rating label — aim for A-rated or above
