Shows how easy it really is. I hope they had an RCD on the extension lead.

When they coming back to finish the job?

Give it a go as you don't have to buy anything.

Multitool and an extension lead maybe.

Do they sell a tape dispenser, think there is a Rymans near my Screwfix.

Is it a good price? At least with Screwfix they have a good returns policy.

Post a close up picture of it. Then it may be able to find something so similar that the difference is indistinguishable.

Is it possible to get a sample, then see if you can mimic the Trex, but cheaper.

Does that bit of the garden get flooded?

Yes, how to get rid of this earworm.

Don't tell @Pocster, he will have all his tenants 'working'.

Could solve the energy storage problem if they made batteries from filling amalgam and aluminium foil.

If you get F-Gas can you recharge car AC units?

Is the left one a metric fine thread? https://www.newmantools.com/tech/threadmf.htm

Friend of mine's brother did the same, but on helicopters. Had to retrain, at his own expense, to work on civilian helicopters. They were often the same machines. Literally the same ones, bought off the MOD.

I have a degree in renewable energy, I am still expected to do these sort of technicians courses. Really does make one wonder what a science degree is for these days.

The heating, or the RPi. I have some code to sense when the power comes on or off.

We are a strange race of people in the UK. We prefer manual cars because automatics are boring. But hate the idea of having to change a heating setting or two, because it is difficult.

@Crofter Do the F-Gas and learn how to size heat pumps, then you can sell a secondary service.

But probably have a lot of opinion about what they cannot possibly work.

Interesting, my house, a small terrace, is 1987 vintage, with only minor improvements.

I think, actually know, that if you fitted UFH with less than 120mm of phenolic insulation, your heating costs would be high. It is still worth insulting the floor as much as you can, it is a large area of heat losses. Large radiators, if the layout is suitable, can be run at low temperature. Placing them on internal walls if possible, or you just get the same thermal problems as UFH. If you are cladding the exterior, have you checked you can do it safely. What are you doing about airtightness? And the associated ventilation and heat recovery.

Telly rots the brain. Why I use a small, portable, radio.

Oh yes. But it makes it easy to convert. I am not sure how good 30W/m² is. It sounds low. My heating season is around 100 days, and I use an extra 1,500 kWh. So 30 kWh/m². Divide by 2400 hours, 12.5 W/m². Under half yours. But it is much warmer where I am. Probably no lower that 8⁰C most of the time. Had 2 frosts last year. Last year my total energy usage worked out at 7.3 W/m². I am sure solar could provide all of that.
