Which? is an independent consumer association that test and survey products and services across a range of categories. A Which? Best Buy sets the benchmark for quality across the products we test.
We have absolutely no influence on Which? directly which is why it is so heartening to see the success we have achieved with Which? since boilers have been included in the study.
Which Best Buys are awarded to products that have either tested or surveyed and been proven to be the best products in that particular category. In the case of boilers, the Best Buys are awarded based on customer feedback.
