There are proper insulation products exactly for the purpose you require. They are called "Cavity Closers" which incorporate a foam insulation which closes the cavity and inbuilt damp proof course.. Regarding gap around the edge, I always use expanding foam around all windows and doors...

I dont know how deep they normally bury these cables... but here where our house is, running accross the front of the house there is the water mains, gas main, cable tv ducts, BT telephone ducts. GAS and electric are on the same side of the garage so probably run parallel pretty much...

I find Wagos good for this purpose. you push them over the exposed wire, then lock them into place with the little lever on them.. so no wire is exposed and circuit rating is maintained (in most circumstances... unless using 6mm or larger) they provide a good secure connection... and if it...

fair enough, lol wasnt arguing that you was wrong just wondered what the reasoning was. Because the power smoke alarms ive had always have a light on them to show they have power, and when the battery starts to get flat they start to bleep. and my assumption and idea was that its always...

just out of curiousity, why put smoke alarms on a lighting circuit? ive had situations before where a bulb has blown which has caused the MCB to trip... tends to be the Halogen bulbs which can do it. so hypothetically, regardless of the probability, In which case, if I was away on holiday...

ideally things like burglar alarm, and smoke alarms should not be protected by an RCD covering other circuits but to meet the regulations they still need RCD protection (if cables are buried less than 50mm and not mechanically protected) so you should consider the use RCBOs for them instead...

The butterfly on a diesel engine is nothing to do with the throttle. Its for when you switch the engine off, and over-run.. normally vacuum operated.

Hi, Thanks True, I forgot about the training and certificate, I am aware a lot of people do PAT testing themselves without being qualified to do so. So better I get somebody to do it, im in essex so maybe a bit far anyway lol. Agree with F-Gas, its illegal to even buy refrigerant...

Hi, I dont know if you will, because its illegal for people to do DIY aircon repairs. So there probably is not much demand outside of refrigeration engineering trade for something like that. Worth asking still, none the less. if not you can order it online from their website, or...

Thanks, will look for a PAT tester then lol

Hi, im an aircon service engineer for cars, and as said that is the dye used in the oil for detecting leaks. you need a cleaner like this, http://www.carairconditioningsupplies.co.uk/caraircon/product.php?productid=33&cat=11&page=2

Hi, Just got a load of kit to start doing air conditioning servicing on cars, involves a lot of electrical kit. does this equipment all need PAT Testing, talking things like recovery machine, vacuum pump, refrigerant bottle heater, antibacterial fogging machine, extension leads.

Yep hips out of date. Yes no mention of repairs.. But original poster didn't refer to a repair they referred to replacement. I can't remember now but it's something like if 75% of the roof is changed then the notification and insulation regulations apply.. Those do still stand as they are...

Dont think it would apply on detached garage. As it doesn't need insulating

Black on white fascia looks the best.

Not the answer to your question I know, but if this is DIY, then replacing a whole roof is notifiable to your local building control.. as they want to see that the insulation has been properly and adequately upgraded. See here...

could be wrong, but isnt the hob cable outside of a safe zone? it has a bend in it which doesnt align with any other accessory.

Then thats what the fused spurs are for. Isolating the appliances in an easy accessible manner above the worktop. Then they have installed the sockets below the worktop, because you need a socket to plug the appliance into. Perfectly fine and normal. Otherwise if the appliance develops...

Hi, is the fused spur definitely for the socket? or for under worktop appliances, like fridge, washing machine, dryer, dishwasher, oven, etc... and just so happens to be located next to the sockets.

Hi, is what they have used rubbery, shiny and flexible? or quite hard? and has a dull finish.. that you think can be painted over. if its the latter, could be they have used caulking rather than silicone outside. Caulking doesnt bode well with cold weather, frost and things. So the...
