Kevin, from Smart Home Improvement People, explains why choosing local installers can dramatically reduce prices
With household budgets under increasing pressure, many UK homeowners are asking a simple question: how can we save money on double glazing without compromising on quality? According to Kevin from Smart Home Improvement People, the answer lies in understanding how the double glazing industry really works.
Speaking after a recent discussion with an industry colleague, Kevin highlighted the significant pricing gap between large national double glazing companies and smaller, local installers.
“Many homeowners are told they should budget around £700 per window, sometimes even more,” Kevin explains. “The reality is, you don’t need to pay that much — and in many cases, you’re paying for layers of overheads rather than the product itself.”
The Truth Behind ‘Buy One, Get One Free’ Offers
One of the most recognisable marketing tactics in the industry is the long-running “buy one, get one free” promotion. However, Kevin says these offers are often misleading.
“The cost is simply shifted onto the other window. Prices are inflated to create the illusion of a discount. You’re not getting anything free — you’re just paying in a different way.”
Why Big Companies Cost More
According to Kevin, large national companies typically have up to nine different people taking a cut from a single job. These can include:
Door canvassers
Team leaders and canvassing managers
Sales representatives
Sales, area, and regional managers
Installers
Corporate overheads
“With so many people involved, companies have no choice but to inflate prices,” Kevin says.
How Smaller Companies Save Customers Money
By contrast, local and independent double glazing companies often operate with just two or three people involved per job — typically the surveyor, installer, and the business itself.
“This reduction in overheads means prices can drop significantly,” Kevin explains. “That’s why smaller companies can often charge £400–£500 per window instead of £700 or more.”
For an average family home with multiple windows, the savings can quickly add up. “Saving £200 per window across nine windows is £1,800 — that’s a family holiday, or much-needed breathing room during a cost-of-living crisis.”
A Smarter Way to Buy Double Glazing
Kevin stresses that this isn’t about aggressive sales tactics or haggling. “It’s simple maths. Fewer people taking a cut means better value for the homeowner.”
While larger companies often promote long warranties and brand recognition, Kevin points out that longevity is never guaranteed. “We’ve seen major companies collapse in recent years. Size alone doesn’t equal security.”
Final Advice for Homeowners
“Always speak to local companies, compare like-for-like quotes, and don’t be pressured by headline discounts,” Kevin advises. “In many cases, choosing a smaller company can save you up to 40% on your double glazing.”
