We live in a village with no mains gas so most are on oil or lpg (we are on oil).

Our direct neighbours have had a new ASHP installed along with some solar panels and had their oil tank and boiler removed, so far so good.
Prior to the install, they did mention that it was going to happen and the potential location of the ASHP which is adjacent to our property and in particular a bedroom. I made my concerns known on two occasions that they need to be sure that it wouldn't cause any impact such as noise or vibration etc. They assured me that "it'll be fine".

Fast forward to last week when it was installed and the intstallers seem to have failed to adhere to the MCS and Planning Portal guidance:

It's under 1m from the property line (maybe 500mm or so)
It's directly next to a bedroom
By the neighbours self admission, it's emitting around 55db but I've not measured it.

So all 3 do not meet the minimum conditions set out by the guidance.

When it was really cold it was running all night and I could hear it all the way down the garden and it could also be heard in our bedroom.

Relationship with this neighbour is currently good, so do I:

A: Not mention anything at all and hope it will be fine and not cause any issues as it's only loud when it's really cold
B: Go full nuclear and demand it gets moved & changed to a quieter model
C: Approach with diplomacy and try and come to an amicable solution suggesting that they need to check with the installer that they've installed it correctly.

Wanted to get some opinions and if anyone else has had a similar scenario - thanks!

C seems most reasonable.

That makes them aware of an issue and doesn’t destroy the amicable relationship like B. B is still on option later. It’s hard to go from B to C.

What sort of size houses are we talking about, is there any alternative place they could have put it?

If its nice big detached houses it's a bit different than if it's a row of narrow terraces.

Not saying it means they should get away with it but those units aren't small so I think a lot of people will have this issue in the long term unfortunately. I guess you can drown it out by getting your own one installed biggrin

Surely the correct PH answer is to hammer frozen sausages into the running fan, thus jamming it for a couple of hours and then filling the heat exchanger fins with rotting meat when they thaw and the fan starts again?

Unless your neighbour is the installer, it's not their fault - I'd hazard a guess that they've raised your concerns with the installer and been told it'll be fine.

TBH even if they haven't, if the installation doesn't comply it's still not their fault.

So it's definitely C.

And if they get the hump, then it becomes a B. But not unless/until.

If relations are good and they're not dicks, no reason why their installer fking it up is a slight on them, so they'll be ok to get them to sort it.

If on the other hand they're dicks once you raise it, then why should you suck it up and not push to get it sorted properly?

I think you need to act ASAP, while it's still in the 'snagging period' with the installers.

If you delay, you will be mucked about until it gets turned down lower in the summer.

I walked away from I house I was otherwise keen to buy over this issue.

Option C, work on an amicable solution

Option C.

Some way of blocking the sound from travelling in your direction might be a better compromise than moving the location.

Agree with C.

If you weren’t on good terms it would probably be another solution but a good neighbour will want to remain so.

Be nice but firm that the install is not acceptable.

55dB is the quietest it will ever be. With age it will get louder.

The road is a mixture of detached bungalows and houses so a fair amount of space around them all - if it was me I probably have put it there but not quite so close.

This is interesting, in the MCS documentation it states it needs to be 42db or lower?

Thank you for all the other replies and I know it was a bit of a multiple choice with only one real answer.

Point taken on the need to move quickly and put the onus on the installer (this has not happened yet but will shortly) rather than my neighbour.

Go full nuclear? Maybe you work in a power station.

What sort of boiler did the ASHP replace?

I've recently had an ASHP installed, in place of a Worcester system oil boiler. It's down the side of my integral garage, just over 1m from the boundary.
Pretty much exactly where the flue of the oil boiler came through the wall, and it's much quieter.

OP, what is your assessment of how they might fix it, based on alternative locations to site it etc? If you can see an obvious solution that doesn't just move the problem to the house on the other side of your neighbour, then that could be offered. But if the only option is say moving it back from the boundary 500mm, that's really not going to do anything re the noise (which is the main problem). All another way to say, if it were installed to regs it sounds like it won't make much difference to you unless something relatively radical is able to be done. Worth thinking about this as otherwise the installer may just rectify to the regs which may make F-all difference to the problems you are facing.
