What Value Score Tells You
The ‘value score’ – calculated by dividing the rating by the price – provides a standardised metric for comparing products across different budgets and performance levels. A higher value score indicates that you are receiving a greater level of satisfaction (as reflected in the rating) relative to the cost.
Notably, TIMCO Damp Proof Course Grey - 100mm X 30m achieves the highest value score (0.981), suggesting it offers an excellent balance between quality and affordability within this selection. Conversely, ToughSheet's DPM has a considerably lower score (0.546) despite receiving a high rating.
How to Use This Leaderboard
- Prioritise products with the highest value scores – these represent the best overall performance for your investment.
- Consider your budget when selecting. ToughSheet’s lower score may be suitable if cost is a major factor, but it's important to acknowledge the reduced rating.
- Use the ratings as an initial filter; a product with a higher rating will likely offer better performance than one with a lower rating at the same price.

FAQ
What does 'value score' actually mean in this leaderboard?+
The 'value score' is calculated by dividing the product rating by its price. A higher value score indicates a better balance between quality and cost, reflecting a more favourable rating for the money spent on that particular product. This allows you to compare products based on their overall performance relative to their purchase price.
Is the cheapest option always the best value?+
Not necessarily. While the 'cheapest' product is listed first, its 'value score' demonstrates that it doesn’t represent the highest return for your investment. The TIMCO Damp Proof Course Grey - 100mm X 30m is the cheapest but has a significantly higher value score than ToughSheet's DPM.
How does the rating relate to the price?+
The rating represents customer satisfaction based on 83 reviews for the TIMCO product, and 14 reviews for the ToughSheet product. However, a high rating doesn’t automatically equate to better value; it's crucial to consider the 'value score', which combines both factors.
Which product is currently considered the ‘best value’ according to this leaderboard?+
The TIMCO Damp Proof Course Grey - 100mm X 30m is currently recognised as the 'best value' with a value score of 0.981. This reflects its high rating of 4.7/5 alongside its price of £4.79.
Which product is the cheapest available?+
The TIMCO Damp Proof Course Grey - 100mm X 30m is recognised as the 'cheapest' product at a price of £4.79.
What makes the ToughSheet DPM stand out?+
The ToughSheet DPM has a rating of 4.6/5 from 14 reviews, but its value score is considerably lower at 0.546. This suggests that while it’s well-rated by its users, the price point doesn't deliver as strong a return on investment compared to other options.
What can you conclude about the Poly Rope DPM based on this data?+
The Poly Rope DPM has a rating of 4.4/5 from 27 reviews, resulting in a value score of 0.519. This indicates that it offers a reasonable balance between quality and price, though not as highly rated or valued as the TIMCO product.
How do I interpret the 'value score' when comparing products with different prices?+
When comparing products with varying prices, a higher value score demonstrates a more efficient use of your budget. For example, the TIMCO’s score of 0.981 suggests it provides greater customer satisfaction per pound compared to the ToughSheet’s 0.546.
Should I prioritise a high rating or a low price when making my decision?+
Ideally, you should consider both. However, this leaderboard highlights that achieving the best balance requires examining the 'value score'. Don’t solely focus on a high rating without considering the product's cost; equally, don't automatically choose the cheapest option if its rating is significantly lower.
Is there any indication of which product might be suitable for larger areas?+
The ToughSheet DPM (1m x 4m) offers a larger coverage area than the other products, potentially making it more suitable for projects requiring significant waterproofing. However, this comes at the cost of a lower value score.
