Double glazing is popular in Southampton and offers significant benefits for homeowners.
Here’s a comprehensive overview:
Energy Efficiency and Ratings
Double glazing windows in the UK are rated by the British Fenestration Rating Council (BFRC) on an energy efficiency scale from A++ (best) to E (worst). UK building regulations now require all newly installed windows to be at least C-rated. These windows can help reduce heat loss by about 18%, potentially saving homeowners up to £235 annually on heating bills.
Key Benefits
Double glazing offers multiple advantages:
- Energy Savings: Reduces heat loss and lowers energy bills
- Security: Tougher and harder to break than single-pane windows
- Sound Insulation: Significantly reduces external noise
- Property Value: Can increase home market value by up to 10%
Installation Considerations
- Costs vary based on materials, window type, and installer
- Financial support may be available through LA Flex for lower-income families
- New building regulations require additional ventilation when replacing over 30% of windows
Modern Options
Manufacturers now offer customisable double glazing with:
- Various frame materials (uPVC, wood, aluminium)
- Multiple window designs
- Different colour options
- Enhanced energy efficiency standards
The costs of installing double glazing in Southampton vary depending on several factors, but here’s an overview of the current pricing landscape:
Average Costs
The average cost for double-glazed windows in Southampton ranges from £450 to £1,200 per window. For a whole house, the total cost typically falls between £4,500 and £7,000 for an average three-bedroom home with ten windows.
Factors Affecting Cost
Several elements influence the final price:
- Window size and style
- Frame material
- Number of windows
- Property size
Cost Breakdown by Window Type
Different window styles come with varying price tags:
- Casement windows: £500 to £1,250 per window
- Sash windows: £700 to £1,500 per window
- Tilt and turn windows: £750 to £3,375 per window
- Bay windows (three sections): £1,500 to £6,750 per window
Frame Material Costs
The choice of frame material significantly impacts the overall cost:
- uPVC (cheapest option):
- Casement: £600 to £1,800
- Tilt and turn: £750 to £2,250
- Sash: £900 to £2,700
- Bay: £1,500 to £4,500
-
- Aluminium and wood frames are generally more expensive than uPVC.
Installation Costs
Installation costs are typically around £250 per day, which should be factored into the total expense.
Potential Savings
While the initial investment is substantial, double glazing can save the average household up to £140 a year on heating bills, making it a cost-effective choice in the long run.
Additional Considerations
- For a 2-bedroom house (4-5 windows), costs range from £1,800 to £4,500.
- Triple glazing, which offers enhanced insulation, costs 30% to 50% more than double glazing.
- Some grants are available for energy-efficient home improvements, such as the ECO4 or the Home Upgrade Grant, though eligibility criteria apply.
When planning for double glazing installation, it’s advisable to obtain multiple quotes from reputable suppliers to ensure the best value for your investment.
What is the most cost effective double glazing in Southampton?
uPVC (unplasticised polyvinyl chloride) is widely recognised as the most cost-effective material for double glazing in the UK. Here’s why:
- Affordability: uPVC windows are typically the cheapest option, with prices starting at around £300 per unit.
- Energy efficiency: Despite being cost-effective, uPVC offers excellent insulation properties, potentially reducing heat loss by up to 30%
- Low maintenance: uPVC is easy to clean and resistant to rot and rust, making it ideal for the UK’s climate.
- Durability: uPVC frames are robust and do not easily break, chip, or warp in extreme conditions.
- Versatility: Available in various colours and finishes, including wood-effect options, uPVC can suit different aesthetic preferences.
While uPVC is the most budget-friendly option, other materials offer different benefits:
- Aluminium: Though more expensive (starting at £600 per unit), it provides a modern aesthetic and is very durable.
- Timber: The most expensive option, but offers natural insulation and is preferred for traditional or period-style properties.
For those seeking a balance between cost and performance, uPVC remains the top choice for most UK homeowners looking to install double glazing on a budget.
What Factors should you consider in Choosing Your Double Glazing Supplier in Southampton?
When choosing a double-glazing company, consider these key factors:
Credentials and Reputation
- Look for industry accreditations such as FENSA, CERTASS, TrustMark, and Which? Trusted Trader.
- Check online reviews, testimonials, and ask for references from previous customers.
- Consider local companies, as they have more to lose if they provide poor service and are often more accessible.
Quality and Standards
- Ensure the company’s products meet relevant safety and performance standards, including fire resistance, thermal efficiency, and weather resistance.
- Look for energy-efficient options with good Window Energy Ratings (WER) and U-values.
- Check for security features like multi-point locking systems and toughened glass.
Customer Service and Support
- Choose a company with a dedicated surveying team to assess your property before installation.
- Verify if the company has its own in-house installation team rather than subcontractors.
- Ask about warranties and guarantees, aiming for 10+ years on products and insurance-backed guarantees.
Transparency and Expertise
- Request clear, detailed quotations that include all costs (products, labour, installation).
- Visit the company’s showroom to see products in person and speak with technical advisers.
- Ensure the company can provide expert advice on the best solutions for your specific needs.
By considering these factors, you can make an informed decision and choose a reliable double-glazing company that will provide quality products and service for your home improvement project.
