No the only requirement is not to overload the cable. In this case the radial circuit is fed from a 16A MCB so no problem just extending it in 2.5mm cable. You could wire an entire radial circuit fed from a 32A MCB as long as you used 4mm or 6mm cable,

In the context of motors, I much prefer the term "Variable Speed Drive" or VSD. It is unambiguous and clearly describes the function, to operate a motor at different speeds.

This Legionella ting is really only a thing if you have private (not mains) water, and the hot water is stored in a vented tank. Treated mains water and an unvented of water tank and there really is no risk. In any event this reg does not stop you storing very hot water, it just requires the fitting of a thermal mixing valve to blend the very hot water with some cold water to deliver the correct temperature to the tank.

i and welcome. Which part of the Loch? not far from me.

Smoke alarm is too close to the corner.

IPX0 is NO resistance to water (first digit is resistance to a solid object e.g a finger, second digit is resistance to water) So I would guess they have a perforated case and any splash of water could get in and upset the electronics. do you have a picture of them?

A Howdens quote is an opening offer to start the negotiations. You will almost certainly get a better deal going to a stone supplier directly for the worktop.

Another "solution" looking for a "problem" It would be interesting to hear one, but my gut says it is not going to be up to my standards.

Beware of bathroom shops. When we looked, I found the one in Inverness wanted to charge almost 3 times the price for multipanel compared to Jewsons price. That's why the advice is not to buy a package.

New CU is fine. Lights should be able to go on a new CU wit RCD's or even better on their own rcbo. The no earth on the ligts means you cannot use any class 1 light fittings or switches.

The replacement water boiler arrived today, very prompt service, and I have just fitted it and it's working. For anyone reading this, it's a Lamona branded boiling water tap from Howdens, the water boiler was badged Redring, but it turns out it is made by ProBoil. The original one was a Proboil 2 and the replacement is a Proboil 2X Their website is here http://www.proboil.co.uk/

On the ground floor, do not bother with any UFH in the entrance hall and stair well. From the past 2 properties, I found those loops almost never turn on, it is an internal space and only a tiny bit of external wall to lose heat. Instead, all those pipes that pass through the hall to get to their final rooms, spread those out at 200mm centres rather than bunched up, and that will give the entrance hall all the eating it is ever likely to need.

Hi and welcome. Moving from the flatlands of Cambridge to the flatlands of Caithness you should feel at home. Plasterers are a rare breed up here, it is far more common for plasterboard just to be taped and filled up here.

Are you miss understanding the purpose of noggins? You seem to be talking of adding them to stop the bend in the 18mm floor covering, which is inadequate and should be 22mm for 600mm centres. The real purpose of noggins is to stop the joists twisting and so reduce the sag along the length of a joist.

So the issue is a bedroom that is so well insulated, it warms up over night with the heat from the occupants. We found that upon first occupying our new house. Part of the issue is the calculated decrement delay was in the order of 13 hours so on a typical day with maximum heat around mid day, the peak internal temperature from that occurs in the small hours, no doubt adding to the bedroom warming overnight observation. Our solution is simple. Open the bedroom window and en-suite window a little at night and let the cool night air in. It only becomes a problem when the night temperature does not drop below 20 degrees, something that does not happen very often up here.

Peter's suggestion is the bees knees but means crawling under to fix the PIR. A half way house might just be to fix battens across underneath the posi joists to support the existing PIR dropped down to the bottom, and use Earthwool as the infill above the PIR. You want te whole floor up to do this properly. Then an air tight membrane all joints taped over the top before putting the floor back down again. P.S Posi joists would not have been my choice. I would ave chosen Engineered I beams. They then are easy to fit a bottom panel of OSB that just drops in onto the bottom chord and you fill with insulation, no web section to have to fill. (that paragraph for the benefit of anyone thinking of using posi joists in a similar situation)

Yes this is a real return transom https://www.scaffolding-direct.co.uk/used-kwikstage-4ft-return-transom.aspx And this is how you use it https://www.avontus.com/blog/how-to-add-a-return-transom-to-a-kwikstage-corner/

There are at least 2 different designs of Kwikstage Transoms, the ones you have pressed out of sheet steel as you have there, and some are made of two steel angle sections and welded together at the ends. I have always viewed them as completely interchangable. I have not seen this "return transom" you mention, do you have a picture?

Howdens own brand. I doubt it's better than Qooker, but it was certainly cheaper.

That will be the LA database that I know exists, but because I have not paid my £150 to Highland Council, they will not tell Royal main. But everyone else has been told.

I came home from work today and the kettle was sitting on the kitchen worktop. Yes the Lamona boiling water tap had stopped heating water. A quick check of records found I bought it from Howdens in November 2019 and a phone call to Howdens confirmed it has a 2 year warranty. They then gave me the phone number of the manufacturer who without quibble have posted a replacement water boiler unit. I will keep you posted.

They must have visited here when nobody was in, because the Land Registry maps have a very accurate footprint of the house marked, and also the footprint of the static caravan. The LR maps also show the house name, I wonder who told them? we didn't

Your electrician should sign the Part P for the electrical work. One would expect an MCS installer to take care of that.

Benefit of a hw tank compared to what? Compared to a combi boiler, possibly greater hot water flow rate, better shower etc. HW tank allows you to use a low power source such as an air source heat pump to heat the tank and use solar PV as well to heat it.
