ASHP Quotes

MoneyGeoff

I have an oil boiler and am off the gas grid. I’ve been getting quotes for supply and fit of a 14 kW ASHP and 250 L cylinder. The engineers that visited confirmed that my radiators and pipework are fine as is.

I tried local MCS-listed installers and also big energy companies. All quotes came in around £15 k, minus the £7.5 k BUS grant, leaving £7.5 k to pay.

I also tried installers not part of BUS; their quotes average around £8 k. It seems the grant benefits the installer rather than the customer.

I’m not alone—only ~60,000 ASHPs were installed in 2024, versus a government target of 600,000 by 2028. Gas boiler installs remain much more common because they’re roughly half the price of an ASHP.

Anyone else finding this? Has anyone found an installer that passes the grant on to the customer rather than pocketing it?

Did you get a quote from Octopus? And a HeatGeek?

I've just run a quote for my property (smaller than yours, our gas boiler is only 15kW) through Octopus's online engine and it came out at about £4K.

14kW is a large heat pump, and (from a quick peek at City Plumbing) the big names all come in at £6k or more. I wonder if the non-grant £8k quote is using one of the off-brand versions?

Most of the quotes are for a Mitsubishi Ecodan they are about £4200 before vat (but there’s no vat on heat pumps anyway).

The quote from Octopus was £6816.38 after the grant. That was in January, I could try again but I think prices are going up. I havent tried Heat Geek, will try them.

Octopus were offering 15 percent off recently so may be worth a quote, they now have two types as well.
