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.

Octopus are excellent - try them

I am writing to report concerns about Mitsubishi Electric UK’s aftercare support for their Ecodan air source heat pump systems. I believe their conduct may warrant investigation by Trading Standards.

I have experienced:

•     Repeated delays in appointments

•     Poor communication and lack of follow-up

•     Difficulty accessing qualified engineers for repairs

•     A complete absence of support

These issues have caused significant stress due to no hot water and no heating. I have made multiple attempts to resolve the matter directly with Mitsubishi Electric UK, but have received no satisfactory response.

I believe this may constitute unfair trading practices and a failure to deliver services as advertised. I am requesting that Trading Standards investigate whether Mitsubishi Electric UK is in breach of consumer protection laws.

Just tried to update my Octopus quote but it was going straight to asking for a deposit, gave up after three attempts but they turned up as emails, same as before at 4.4k but link to their factsheet suggested it might be 3.9k. Next day had three different Octopus agents phoning me up as they had three quotes on their system but at least they are keen but I am not, just keeping up with the costs in case I actually get Local Grant via govn schemes for "free" solar and heat pump. I could have done it on Eco4 Flex (both for households with under 31k income but not on benefits) but they wanted me to top up the grant, circa five grand. EPC is high D so I can't do any singular upgrades as that would push me into C and not eligible for the grants. Only want solar really but will take the heat pump to get it for free and then get rid of the dreaded gas standing charge. Octopus agents had no info on future A2A systems coming under any of the grants, BTW.

It might be better to start your own dedicated thread so that the matter gets the attention it deserves.

Thanks, that's useful to know.

They have their own thread; MSE cut one of their (several) posts out by itself.

Thanks for the comments. Octopus are too expensive at £6816.38 + £7500 bus grant. I couldn’t get a quote from heat geek, probably because my house is E rated. I’ve spoken to the council and am applying to one of their energy schemes instead.
