How we assess heat pumps
We assess individual products and closely related ranges—not brands as a whole. Different ranges from the same manufacturer can earn different tiers.
A higher tier doesn’t automatically mean the best installed value for every home. Each recommendation considers performance, construction, long-term ownership and practical suitability.
