Gutters direct rainwater away from the roof and foundation of your home, protecting it from water damage. Choosing the right material for your guttering system can make a huge difference to its longevity, cost and maintenance.
While metal options like steel, aluminium and cast iron have their strengths, UPVC is often considered the best choice due to its low cost, low maintenance and versatility. In this guide, we’ll break down the pros and cons of plastic and metal guttering to help you make the right decision for your property.

Plastic vs metal guttering
When deciding between plastic vs metal guttering, you should consider the cost, maintenance and lifespan. While they each hold their own benefits, UPVC is often considered the best option for UK homeowners.
What is the life expectancy of UPVC guttering?
UPVC gutters can last anywhere between 20 to 30 years with the right care. Regular cleaning and inspections can extend their lifespan, ensuring they remain effective at redirecting rainwater away from your property.

Why is UPVC guttering better than metal?
UPVC guttering is typically more affordable and easier to install than metal alternatives. It requires minimal maintenance and doesn’t rust, making it a practical choice for most homes. Additionally, UPVC is available in a range of colours and profiles enabling you to customise the look of your home’s exterior.
Alternatively, metal gutters like steel and cast iron are heavier, more expensive and prone to rust if not treated regularly. Although they might last longer in some cases, the additional cost and maintenance often outweigh the benefits for residential properties.
The most cost-effective guttering
If you’re looking for a budget-friendly option, UPVC is the clear choice. Not only is it cost effective, it's lightweight, so can reduce installation costs. It’s also low maintenance, which saves you time and money in the long run.

The best guttering material
Although the ‘best’ guttering material depends on your property’s needs and aesthetic preferences, UPVC is generally the most practical choice for UK homeowners. UPVC is affordable, easy to maintain and versatile to suit most home styles.
For heritage or high-end properties, materials like cast iron or copper may be worth considering for their durability and aesthetic appeal.
Choosing the right guttering material is an essential part of protecting your home from water damage. While both plastic and metal gutters have their strengths, UPVC often stands out as the most cost-effective and low-maintenance option for residential properties.
