I am having an ongoing discussion with my plumber about the installation of my ASHP system. Further to previous posts on BuildHub (and very helpful feedback) and a non-committal review by MCS following my complaint I am now looking for someone to review my system and advise where there are issues with installation and non-compliance with MCS or any other relevant standards.

 

I am between Bristol and Swindon.

 

Does anyone have any recommendations of any companies who would cover my area for this sort of review.

 

As always with BuildHub, I very much appreciate input from everyone!

Can't help with a name or company - but what appears to be the issue(s)?

Can't give you a name for your area either, but a few things will make any review quicker and cheaper.

Before anyone visits, pull together the MCS certificate, the room by room heat loss calculation, the design flow temperature, the emitter schedule showing each radiator's output at that flow temperature, the pipe sizes and the commissioning sheet. A lot of compliance problems show up on paper first: emitters too small for the design flow temp, no proper heat loss done, or a unit sized off a rule of thumb. If your system has a monitoring app, a week or two of flow temps, run times and electricity use tells a reviewer more than a one hour visit.

When you ring round, ask for an independent heating engineer or heat pump consultant who does design and commissioning reviews and isn't trying to sell you a replacement system. Ask them to report against MCS MIS 3005 so the findings line up with your complaint.

On the complaint side, if your installer was signed up to RECC or HIES as part of their MCS registration, that consumer code's dispute process can often go further than MCS itself, and an independent report gives it some teeth.

What are you actually seeing, high bills, cold rooms, short cycling or noise? That would help people here point you at the likely cause.
