Are Your Windows and Doors Costing You Money?

Old or poorly installed windows and doors could be a major source of heat loss in your home. That means higher energy bills and colder rooms.
In this guide, you’ll learn how to assess your current windows and doors and what options offer the best value if you’re considering an upgrade.
How Much Heat Are You Losing?
Windows and doors can account for up to 20% of heat loss in an average UK home. Draughts, single glazing and poor seals are common culprits.
Signs your windows and doors are underperforming:
- Condensation between double glazing panes
- Noticeable draughts or cold spots
- Difficulty opening or closing
- Damaged seals or visible gaps
Simple Fixes to Improve Performance
Not every issue needs a full replacement. Consider:
- Draught-proofing with self-adhesive strips or brushes
- Thermal curtains or blinds to reduce heat loss at night
- Secondary glazing for period properties or flats
- New seals to fix minor gaps
These options are often cheap and can cut heat loss quickly.
When to Replace Windows or Doors
If your current fittings are more than 20 years old, or show major signs of failure, replacement may be more cost-effective long term.
What to look for:
- Double or triple glazing with low-emissivity (low-E) coatings
- A-rated window units under the BFRC scheme
- Energy-efficient external doors with good insulation properties
- FENSA-certified installers to guarantee compliance with building regulations
Material Choices
| Material | Benefits | Considerations |
|---|---|---|
| uPVC | Affordable, low-maintenance, good thermal insulation | Common in modern homes |
| Timber | Traditional look, durable with care | Higher maintenance |
| Aluminium | Strong, slim frames, modern appearance | More expensive, thermal breaks essential |
Grants and Support
Some households may be eligible for support under local energy efficiency schemes or ECO4. Check your local authority or energy provider for offers.
Frequently Asked Questions
How do I know if I need new windows?
If your current windows are difficult to open, draughty, or over 20 years old, an upgrade may improve energy efficiency.
Is triple glazing worth it in the UK?
Triple glazing offers better insulation than double, but the benefits vary depending on your home’s exposure and budget.
Can I claim a grant for replacement windows?
Possibly. Some ECO4-funded schemes offer support, but eligibility depends on income, location, and existing insulation.
Do I need planning permission to replace my windows?
Not usually, unless your home is listed or in a conservation area.
