thats where the pressure is when they are tightened down.

The bottom of the panels should not be in contact with the tiles as it will push them up when the panels are tightened down. it does show this clearly in the manual. strange they have given you the correct side flashing but not the top, if you look at page 29 there is a metal flash at the top onto which the sticky crap goes otherwise you would have to stick it directly onto the panels!

The top shouldnt have sticky flashing. They come with a metal tray that sits on the top edge of the panels, the slates/tiles are then cut into to it flush.

they have fitted the panels too low and the weight of them is kicking up the tiles. You should see the bottom flashing. Out of interest can you show a picture of the top as well. We had the same panels and tray, i really didnt like the sticky flashing and used lead instead. Page 17 of the manual shows the correct installation method. https://www.gseintegration.com/wp-content/uploads/2021/07/IR_EN_MI-v11.3-4.pdf

leaded flat roof can look nice, much extra cost and faff though....

do some more research. your rads will need to double in size, if they are fed by microbore pipe this needs to be replaced. You WILL be paying a heck of a lot more money on your heating bill compared to gas, maybe close to treble depending on how insulated the house is. Also take into account the racket the outside unit makes if your neighbours are close to you. Not many pro's and a lot of cons unfortunately. You will be pushed to get unbiased facts here as you will no doubt read ....

ask the brickie to tell you.

pole to pole is covered by wayleave or have I got the wrong end of the stick ?

anna, send your drawings to get priced you have been given the links. No point any of us giving you an example quote as it wouldnt be of any use. to give you an example, your looking for a new ford mondeo. We give you a quote for a Bently. See its silly. Get your build priced, then get builders to quote based on it.

Certainly does, easier as well if you do it properly with the right machinery.

can lead a horse to water etc

must be doing them wrong to make hard work of it, loads are designed in so not an issue. Carry on humping conc I know which I and the large housebuilders prefer.

disagree. concrete is hard work and will never be as flat as a screed. They are pretty much cost neutral so B and B every time.

block and beam every time.

two options, you only have to pay a nominal amount of £100 on the credit card, the rest can be BACS and you arte covered for the whole amount. option b:, pay the whole amount using your overdraught and you are similarly covered.

walk away.

get it QS'd first then you have a base point of cost, this will be usefull to builders as they can see exactly what they are pricing for down to the last nail and screw. https://www.estimators-online.com/

seems a dead easy irrefutable solution is to leave the temporary water connection not connected to the house. Who is to say there is a 'T' underground with a temp pipe into the house ......

they are right, you can reclaim. In their shoes, every tom dick and harry could say the windows are for a new build to get out of paying vat which the window company would then be liable for.

perhaps i am not understanding it, would there be no airflow from one side to the other ?

how about using a telescopic vent and bring the top up into the kitchen cupboad and out the wall, just need a single slot through the floor and wall then seal both. Then remove/block off the existing to stop water ingress. https://stanleyjohn.com/products/telescopic-air-vents-accessories/

Once you have removed the old, try using a profile tool it gives a much thinner/professional look than wiping a finger down the length. https://www.toolstation.com/cramer-fugi-profiling-tool-set/p46602

face to face, pop round his house and come to an agreement, if the 75% you have paid is legit then happy days if its not then you want some back. Much better to do face to face as he will know your serious, dont be confrontational. Last resort small claims court, dead easy to do.

my concern is mould growing in the condensate being then blasted throughout the house.
