  1. For my electricity I had to chase them up as they were trying to bill my plot instead of posting my bills to my home. I haven't really used any units yet but there is still the daily charge to pay.

    Should I fit solar panels

    Using my above example, by not buying slates it reduced the cost of the PV install by approx 25%.

    Should I fit solar panels

    I just fitted 12x 300w panels using gse mounts. For the panels, mounts and all the other bits and bobs needed, cost 2.5k Inc vat and delivery. The mounts saved approx 26m2 slates. Think it was 28 slates p/m at 0.75ea. So approx £550 slates. So I'm looking at around £1500-1600 all in once we get the vat back. I have not included labour as we did the panels ourselves with the help of the roofer, so I think this would have been similar to the cost of him slating it.

    Foil faced insulation underfloor

    Thanks. I'll see what depth I have as the hardcore is in and compacted but I can't remember what depth I have left to the FFL.

    Foil faced insulation underfloor

    Sorry I got confused as I misread Peters post. Yes dpm then PIR then another dpm to protect from screed. Why the recommendation of 25mm eps instead of blinding?

    Foil faced insulation underfloor

    What's the thinking behind the double dpm? Just to save on messing around with blinding?

    Foil faced insulation underfloor

    That's what I am hoping, I'd be able to reduce the cost of insulation quite a bit by going without foil.
  8. Morning, With regards to PIR insulation when placed under floor, does it matter about being foil faced? My floor will be concrete slab / DPM / 120-150mm PIR / UFH pipes / 75mm concrete screed. If the answer above is yes, is there anything I could use on top of the PIR to replicate the foil face, like an aluminium VCL like this? Thanks

    Part 26 - Wall mounted Solar PV system

    Looks good, keeping the top in line with the windows was a great idea. I'm curious about the DNO notification. Was your electrician MCS certified or just a regular sparky? My install will be DIY and I don't want to have to find a MCS company to try and sign it off.

    DPM above or below concrete slab

    Thanks, that clears it up. Yes it is new build. Make up is to be hardcore, 150mm reinforced concrete, PIR and screed on top. So DPM below the slab and a polythene below the screed.
  11. My floor will be made up of hardcore, 150mm concrete, PIR insulation with underfloor heating clipped and 75mm cement based screed. Just wondering what is the preferred place for the DPM? Below the main 150mm slab or on top of the slab before the insulation? Thanks

    GSE in roof system

    Both wagner and midsummer said that the mounts could be fixed directly to the sarking. It is a garage roof so will never be a warm roof.

    GSE in roof system

    Sorry I just screenshotted that from the manual to show the centre. I wasn't suggesting drilling the GSE mount. Mine are mounted on sarking as we are in Scotland, so unable to run cables under the straps/battens. I presume for me I will need to just run each set of connectors through the sarking in the centre of every mount and do the connections inside?

    GSE in roof system

    Has anyone used GSE in roof system? It is not clear in the manual where to pass the cables through. I presume you can just drill a hole anywhere in the centre of the mount, as this should be a dry area, and pass the cable through? Thanks

    Solar on garage issues

    Thanks for the advice on the CU. What terminals did you use inside the box? On the subject of solar, would it be possible to stay off grid with the system I spoke about? As I would like to avoid the cost of having a MCS installer involved and there is no point as FIT wouldn't be applicable? I presume a normal sparky won't be able to sign the system off.
