Homeowners across the UK are increasingly recognising the value of double glazing for both new builds and period properties. It’s not just about looks; double glazing delivers a wealth of benefits, including better energy efficiency, quieter interiors, and added security.

In a time of increasing heating bills, choosing quality double glazing can be a cost-effective moves a homeowner can make to cut expenses over the long term.

Key Factors in Selection

Not all double glazing companies are created equal. Keep these factors in mind:

1. Experience and Reputation

A company’s history speaks volumes. Look for a firm with years of experience in your area. Understanding listed buildings, where specific requirements need attention.

Check online reviews on trusted sites such as Google Reviews to gauge a company’s reputation.

2. Accreditations and Compliance

Always verify credentials. Confirm the company is registered with CERTASS. These accreditations guarantee the installation meets current building regulations.

Ask about guarantees. A trusted company should offer a solid guarantee covering faults and defects.

3. Range of Options

You get what you pay for. Seek a company that offers multiple products—including slimline aluminium or traditional wood frames. Don’t be afraid to ask about the energy rating of each option.

4. Transparent Pricing

A detailed quote is a must. Professional installers will supply a clear quote that details all costs—with no hidden surprises.

Avoid pushy salespeople or unrealistically low quotes. A good rule of thumb is: the cheapest option isn’t always the best value.

5. Workmanship

Top-quality products need expert fitting. Ask if the installers are employed directly or subcontracted. Permanent staff often ensure more reliable results.

If possible, visit previous projects or ask for photos to evaluate the craftsmanship firsthand.

Why Timing Matters

Don't wait for problems to escalate. Older windows can let in drafts, costing you money each year. Warmer seasons are often the ideal periods for installation, as conditions are more favourable.

The Bottom Line

Choosing the right double glazing company is key to long-term satisfaction. Do your homework, speak to neighbours, and ensure every detail is clear.

With the right partner, you’ll enjoy a warmer, quieter, and more secure home for many years to come.
