the confusion that had been caused.”

“EXTREME CAUTION!!! Octopus Energy dramatically over estimated heat loss when doing my home's Air Source Heat Pump (ASHP) survey. Their survey and subsequent system could have cost me ALOT of wasted money!!!
I purchased an Air Source Heat Pump (ASHP) survey from Octopus in December 2025. I really wanted to use them as my installer/provider for a ASHP but there heat loss estimates were likely to be extremely incorrect!
Octopus surveyed my house and stated my heat loss was 13600 watts and that I needed a 15kwh heat pump. They then changed the estimate to 12252 watts heat loss.
However an alternative provider stated that was unrealistic and calculated my home's heat loss at c. 8500 watts ang therefore I only needed a 8kwh heat pump.
Octopus' survey is extremely concerning as I understand an overestimated heat loss calculation will result in an inefficient (and costly) oversized heat pump unit! My understanding is that an oversized unit reaches setpoint quickly, then turns off and on frequently. This reduces efficiency, increases wear on compressors and contactors, and can dramatically shorten the unit's lifespan as well as increasing electricity bills (something that would benefit Octopus).
CAUTION: my understanding is that Octopus' heat loss estimates are often seen as high or conservative; potentially leading to oversized heat pumps, because they use STANDARD survey methods (MCS) and make cautious assumptions about factors like air leakage, required room temperatures, and radiator performance.
My house is extremely efficient with my extension being built to 2016 regs, all rooms having underfloor insulation, efficient modern double glazing and even draft excluders on interior doors!
Octopus Energy's surveying approach could result in you wasting £1000s!!!!!!
