UPVC vs. Timber Sash Windows: Cost Analysis
The material choice significantly impacts both initial cost and long-term value:

| Initial Cost | £500-£2,000 | £1,500-£3,000+ |
| Maintenance Costs | Very Low | Moderate to High |
| Lifespan | 25-35 years | 50+ years with maintenance |

Special Considerations for Oxford Properties
Oxford’s rich architectural heritage means there are special considerations when calculating UPVC sash windows cost:
Conservation Areas
Many Oxford neighborhoods are designated conservation areas, including:
- Jericho
- North Oxford Victorian Suburb
- Central Oxford
- Headington Quarry

In these areas, planning permission may be required, potentially adding £200-£500 to your project costs. High-quality UPVC sash windows that closely mimic traditional timber designs are often acceptable.
Period Properties

- Custom sizes to fit non-standard openings
- Special designs to match architectural features

- Sympathetic styling to maintain character
These requirements can increase costs by 15-30% compared to standard installations but are essential for maintaining your property’s character and value.
