Speak to your neighbour 2 doors to the right in your aerial picture. It looks like he has done what you are proposing (with a flat roof) Ask if it was PD or needed planning permission and if it needed PP was it easy or difficult.

But if you fit 20 in a big kitchen and a few years later a couple blow, and you can't buy replacements that match, you DO worry. That is why I advise people if you are buying fittings with no replaceable bulbs, buy a load of spares now, while you can.

If it is in a grass verge and there is no tarmac pavement involved I would have no hesitation digging it up to have a look. Just have some kind of barrier ready to place around the hole if it is going to be left open.

What boiler? assume gas or oil. You need to measure the flow temperature coming out of the boiler, it sounds like the boiler thermostat has failed and the burner is running continuously and overheating the water. Turn the boiler on and watch while measuring the flow temp, does the burner shut off after a while of just keep on going and going?

I think the LED GU10's I have were Screwfix cheap ones (probably LAP) sold in boxes of 10 for about £1 per lamp. Only 2 failed so far in nearly 5 years.

That's one of those "because I can" projects. We all know it would be a whole lot easier to drive four 7 segment LED displays from the Arduino........

Then they need to supply parts at a reasonable price. There are 2 headlights in a car (sometimes more) I simply do not believe at manufacture time they cost £1600 which would have been more than 5% of the cost of the car (possibly a lot more)

That is criminal, I thought things had to be "repairable" now? That's one more thing on the list to check next time I buy a car.

Under the insulation is fine. It's when it is buried within the insulation you need to worry about derating cables.

No, 2.5mm And for the period it was an incomplete ring, the two ends were each fed from their own 16A MCB which was changed to a single 32A MCB when the ring was completed.

At least you had the sense to fit light fittings where you can change the bulb. There is a growing trend for downlighters to have non replaceable bulbs. If anyone asks me to fit some (I would not buy them) I advise them to go and buy a box of spares, on the basis when one fails in a few years time, you probably won't be able to buy identical replacements.

Why was there a gap between the wall and stringer? There are not in my house (but I fitted the stairs)

As above. Why would I want a split unit that requires an F gas engineer, so I could not fit it myself, and why would i want the noisy bit with the compressor inside the house?

My house had a full as built SAP done to get the as built EPC. The energy input that predicted in spite of having all the correct data is about 3 times as much as it actually uses. Jeremy's spreadsheet gives a far more accurate prediction.

Or better still start a new thread in the appropriate section. This is the place we welcome new members.

Can you explain your problem please? Do you actually have a problem with something not working? Or a theoretical problem because something has been done in practice in a way that differs from how you think it it should have been done?

Most of my beer is brewed in my utility room. Avoids the minimum price per unit. 😏

Yes we in the North should get the cheaper electricity to encourage people here to switch to heat pumps and use up some of that lovely renewable power, and it is folks in the south that should pay the grid surcharge to pay for the work allowing them to share in the green revolution.

No point having an unachievable target. Lets instead spend the money previously spend setting all these targets, on actually getting on and joing the job as fast as we can. It will take how long it takes.

Exactly. There are bottlenecks on the HV grid that are already at capacity. Some wind farms have to shut down at times as the grid cannot take the power they generate * And it is taking an age to upgrade the grid. For example the proposed third HV line to the far north passing us, has been in design and consultation for about 10 years so far. * One of the wind farms near us, they are building an electrolyser to generate hydrogen using power directly from the wind farm I am sure I have discussed this, I think it is a bonkers idea. The hydrogen will then be taken by road to distilleries to power them. Surely it has to be better just to build the power lines needed and feed them with electricity?

Seeing the reaction being portrayed on news channels, you would think scrapping unrealistic targets means we are going to stop building new windfarms etc and just give up. No it does not, it means we are going to continue making improvements as fast as we can without silly unachievable targets clouding the issue.

That's the problem in the article. The HV network in that region has no extra capacity. All the tree huggers that think every house should have a heat pump immediately and every car should be an EV immediately, forget that if that happened too quick we would have the same problem.

If everything is to go electric, then the grid capacity everywhere has to expand. I wonder where will be the first to hit this situation in the UK? I hope there are not any self builders with part built houses now finding they can't get connected?

Now turn the hob on. That looks to be reading room temperature? What are you expecting to cook at 20C?
