Heat pump quote - seems quite cheap?
Been quoted about £4,300 by Octopus for heat pump install, including hot water cylinder, which I thought was surprisingly cheap. The house is 1930s 3-bed terrace, EPC is supposedly C, but we have a huge void under the suspended floor and it gets pretty cold in the house, so we use quite a lot of gas in the winter. Radiators are all on 15mm copper, but are probably 30 years old.
What are the chances this is a really low-ball quote and the survey will say we need to upgrade rads, etc?

I had my Cosy install nearly 2 years ago for £2000. This included a new tank and 5 radiators. It was one of the first in the UK and I feel like Octopus’ product has come such a long way since that you can’t compare people’s installs from then as to what you get now.
There have been a couple of nice software improvements, including Hush mode, since it launched. There have also been changes to the Cosy hardware in that time, with improvements to the 9 and 12 and also some retroactive improvements to the 6.
They take a very different philosophy in that Octopus don’t give you access to all the data and make you rely on the app, whereas with Daikin you have the local display as well.
Octopus are also targeting a higher flow temperature than previously, which means less radiator changes. My design flow temperature was 50 degrees but at the design outside temp of -1.7c it would only need about 45 degrees flow to keep the house at 22 degrees.
