ASHP and AC planning permission

Harry1986

I am looking for some help:

- I was in the process of installation of AC and they have hung three indoor units and some trunking and have done fuse board work but nothing is connected in terms of external units or pipework to internal units.

- i had ASHP planned to installed in June by Octopus Energy in June,23 and they said i will need planning permission before they install it.

I have given written consent that i will not carry out the rest of the AC work and have applied for planning permission to get that installation done as nothing is operational or attached.

Which Octopus agreed to and now they being a pain of saying if they have touched fused board or can see any internal unit they cant install it as this is against BUS grant permission and MCS rules.

I tried to read on both of those websites and neither of them mentions anything about any of the rules they keep telling me.

Only simple rule is that to get additional unit outside i will need planning permission which is in progress.

Both of the units noise assessment are within allowance limits and location of pump is going to be against new wall of my extension which wont be visible to people walking on the road or hardly to my neighbour.

Really just trying to understand if Octopus is being just a big pain or am i missing anything

Have you seen this lengthy discussion about planning permission and Octopus?

I Have read that but i dont have functioning AC in house yet like that post and my noise asessments are within the limits and happy to process with planning application just want Octopus to complete their installation under permitted development rights and i can wait for AC for planning to be approved

I am having a heat pump fitted by Octopus in June.

I have had the planning issue referred to above.

How do they know about your air conditioning? I assume it wasn't there when they surveyed?

What have you done to the `fuse board' exactly?

If the indoor units are not connected to anything, why don't you just take them down?

I'm not sure why it matters what you have on the internal walls.

Ask them what the problem is.

I Did mentioned it to surveyor which was taken in account for size of heat pump.
Inside houses the units are just hanging on wall.
Fuse board the contractor have invited electrician to install a cable and isolation switch needed for the outdoor unit but nothing is connected to it.
They just making up their own rules to delay instalaltion

Like I said, my installation is in less than three weeks.

I don't think they are making anything up to delay installation.

I think the problem might be something to do with having taken account of your new system when calculating the size of your heat pump.

What has your air conditioning got to do with your Octopus install?

I know your air conditioning can heat, but have you really set it up so you need both running to meet the heating demand?

In order to comply with the grant and MCS rules the install has to be commissioned at the specification agreed at the time of survey and grant application.

I have to remove a perfectly functioning radiator in our kitchen because Octopus couldn't assess it's heat output and did not have a suitable replacement.

The radiator was left out of the heat loss calculations and cannot be present at the end of the install.

I can, of course, put it back when they have gone if I want to.


If you have made your Octopus install in some way reliant on your air to air install then I think you may have made a mistake.

Whatever it is, you need to do what they say otherwise they won't install.

Nothing is in surprise to them and they were aware of all the work being carried out on the house and With regards to MCS rules the install will be commisioned at their agreed survey and same for grant

If it is all as agreed why are they asking you to make changes?

You said this

I Did mentioned it to surveyor which was taken in account for size of heat pump.


How did your air conditioning system affect the size of heat pump Octopus install?

I can't see any connection between the two systems?

QrizB

I think this is related to the terms of the £5k heat pump grant.

Under those terms, the newly+installed heat pump has to replace the existing heating system.

If you've got an AC system being installed, and you don't want Octopus to decommission it as part of their heat pump installation, you won't qualify for the grant.

Are you expecting to receive the grant towards the cost of the heat pump? Have you discussed whether you could pay an extra £5k and have the work go ahead despite the AC system?

You may right.

The OP said that the surveyor took his air conditioning system into account when deciding on the size of the heat pump.

The OP hasn't answered how it was included but I was expecting them to say that  the air to air has somehow been included in the heat loss calculation and was going to provide part of the heating demand.

I would guess the new air to air is not the existing heating system.

I have an install coming up with Octopus and I can have an air conditioning system installed at the same time as their ASHP is fitted. 

All you need is planning permission.

The OP doesn't have planning permission.

I think the problem is as simple as having made changes to the house since the survey, the OP has started installing another heat pump that wasn't there when the house was surveyed.

Yes, all i need is planning permission and have already applied for.
Issue is i have applied for the AC commisioning on property.
All i have is internal units hung on wall nothing else.
AC outdoor unit is not connected to mains or to the indoor units.
Octopus making a fuss regarding not to install their system which will replace my boiler and more focusing on the AC side which is none of their concern.
If they did the work and week after i installed AC it wouldnt matter to them what i do on my property.
All they not getting is that i am allowed to have their ASHP under permitted development rights and AC will be installed with planning permission
