    How do we find out if our building has rising mains?

    Those red and black meter tails on the supply side to me need updating as a very minimum. You could test the water by notifying your electricity supplier of a dangerous cable on their equipment, which they should repair free of charge. If when they come they say it is not their equipment then...

    How do we find out if our building has rising mains?

    That description says to me it is a terrace house or 4 plex house not a maisonette. ? Ask the management company exactly what they are proposing to replace? Or just leave it and see if the buyers solicitor mentions it?

    "My oven smells of grim cheese when I use it"

    I do not like many of the modern oven and hob terminations, while they may work, most of the time, something about them never gives me much confidence they have been designed well.

    "My oven smells of grim cheese when I use it"

    Usually hot plastic used to be a fishy smell. Obviously plastics have changed.

    Favourite job?

    I always enjoyed fixing faulty central heating wiring. I was often called by my plumber mate to sort tings out. I am staggered by how few people actually understand the wiring and the actual function of a correctly operating heating control. Most just buy a standard wiring centre and connect...

    "Specialist" Contractors

    So I think we can all agree that the system is broken, if the MCS requirements add so much extra work to a job, that the extra work eats up the grant money paid by the government, so the consumer gets their ASHP no cheaper and the contractor ends up with all the grant money to cover the extra...

    "Specialist" Contractors

    The one that irks me at the moment is people keep posting very high quotes to have an ASHP installed. Typically £6K or more even after the £7500 BUS grant has been subtracted. Then today someone posted a quote of just over £8100 with no grant (not eligible) So I posed the question, if the...

    "Specialist" Contractors

    Anything mention "MCS" seems to just mean "double the price"

    Electric shower leaking and produce static shock

    Honestly Triton showers are so cheap I would not mess about trying to fix it, just buy a new one. If you get the same sort then keep the old one as spares. Might be best to get an electrician to check the wiring to the shower in particular to check the earthing is okay.

    3-phase to new build shed or annexe first?

    You are allowed 16A per phase without seeking permission so that's 3.6kW for single phase or 10.8kW for 3 phase. Fine if you are SURE your 3 phase meter does net metering so PV export on different phases to where the house is consuming power does not matter.

    External Electrics

    If it was in a written spec that there were to be 2 cables and they only fitted one, make them lift the patio, lay the second cable and re lay the patio at their expense.

    3-phase to new build shed or annexe first?

    No reason at all why not. My supply is still in a meter box on the boundary of my plot. I saw no reason to pay to have it moved. If this is self build in any way, take a look at the buildhub forum.

    Connecting two power supply units for maximum output

    Basic ohms law. You have a power supply of a particular voltage and a load. the impedance of the load will determine how much current flows. If you double the capacity of the power supply, it is still providing the same voltage, so the total current is still determined by the load. So you...

    I would say an underground Y potting box.

    Whos job is it to mount an electric shower

    For boilers I make all the electrical connections and the plumber does the water and gas (or oil) usually working at the same time. I am usually present for first firing to check the controls work. I don't think I have yet met a plumber who has wired a 3 port mid position valve correctly. And...

    Whos job is it to mount an electric shower

    It helps when you know all the local plumbers and can talk to them and work with them. With services coming through the wall from the airing cupboard you could mount the shower to the wall before either came, either the tiler or the home owner could do it so they get the shower exactly where...

    Supply voltage versus voltage rating

    We live in a world in the UK where we now pretend we have a 230V supply voltage, but I have yet to find one and most are still over 240V. I have not yet known any "230v" equipment blow up because of it.

    Catch 22 Confused, Need a straight answer. NAPIT Requirements for Self Employed / Sole Trader

    I will spell it out. There is no part P in Scotland. If you are competent, you do the job, issue EIC or MWC and that is the job done. Just like it used to be in England and Wales. I have never been a member of a CPS scheme. And for notifiable work, which includes new builds, I just give my...

    Catch 22 Confused, Need a straight answer. NAPIT Requirements for Self Employed / Sole Trader

    Since @StevenF is in Northumberland, he could come to Scotland. Do 2 qualifying jobs for inspection by his assessor quite legally as (read my signature about Part P and Scotland) Get his registration with his scheme then go back and work in England.

    If your heating is gas, why is your electricity bill so high?
