Yep. Got a heat pump, but also got a 520hp twin turbo Alfa, was on my 2 stroke enduro motorbike today. Yes net zero, should mean - No overseas travel, little or no imported stuff, we all seem to live on, No one states it has to be this, so nearly all isn't, it's the same stuff as a hundred years ago, so concrete; CO2 intensive to produce, gives of CO2 while going through the curing process. Etc etc... not net zero compatible really. By no stretch is it going to be a few compromises.

If building regs says you need one - you need one. It does say that, so you do. Why waste effort trying to push against the tide?

Are you sure, not what building regs says!

I bought nearly all my insulation online, way cheaper than BM. But prices change daily so once you find a deal buy it may be more expensive tomorrow.

Can you not fully fill with 140mm frametherm? Then kill the thermal bridge with either insulated plasterboard or PIR (full sheets) batten and plasterboard. Dump the super quilt.

May have missed it h not read whole thread, but what about proper standing seam clamps https://www.renusol.com/en/solar-panel-mounting/metal-roof/standing-seam-connections/

We have blinds inside rooms and they do a fine job of keeping the temperature manageable. If you don't have external blinds and curtains do a good enough job. Our last house was curtains and big single glazed south facing windows - that was fine also Some new ones (ASHP) on eBay for below £1500.

I doubt building control would be happy. Why does a rain water soak away from have to be big or expensive. In it's simplest form it's a hole lined with membrane a 110mm pipe has slots cut in the bottom and it's back filled with crushed rock. You don't even need crates. We ended up with 2 and they took half a day each - one man and a digger. Ours before and after filling for 250m² of roof.

Our strategy is Purge in morning when outside is cooler than house - open windows etc. Blinds and windows closed until house is hotter than outside. Then if still getting solar gain, leave blinds closed, but open windows to let outside air in.

I would be rewiring, plus all new switches and consumer unit. Isn't always the correct thing to do.

What thickness of frametherm?

I'm in Scotland and the structural engineer is responsible for the full structural design and provides the whole house certificate. Without it you pay the council extra, have delays getting a building warrant and have to provide full calculations.

Not necessarily, we have no steel ridge, we used a glulam beam and pozi rafter. We found the joinery company we wanted to use, they did all the liaison with the roof designers and suppliers. Once completed our structural engineer was the approver and certifier.

The unit you are discussing is a ventilation unit it is likely to exchange the air in the building once every 2 to 3 hrs. Aircon will do the same, many times per hour. Ventilation flow rates are just way too low to effectively cool anything. MVHR doesn't cool as such.

No it's an electric vehicle with range extender. Range extender is a small engine running at a fixed speed and is there to charge battery while you drive. So you then get a full battery distance plus how ever big the fuel tank. On a long journey you could just top up with fuel and off you go again, instead of waiting for a charger to become free.

It has to be remembered that £22 billion is pledged over 25 years, not a project today or tomorrow.

All true but really a different discussion. We start to discuss population growth, no additional schools, hospitals, no additional social services provision etc. Net zero or not, isn't fixing those broken things soon. Not sure it's making it worse, it's a mess, but providing stuff like wind energy or not, isn't going to produce more or less doctors it's a different and difficult bucket that one party politics, and a short term outlook, decades of under investment are to blame. We could always go back to Britain's hay days, coal fires, steam trains, coal fired industrial growth, acid rain, smog; that killed, child workers. We stopped that the country is better off without it. So why wouldn't we be better with clean energy, clean industry? Get PV, get a heat pump, get low cost heating and zero cost cooling. Washing machine on, ovens been on, immersion is on - all provided by PV, what's not to like. Roll on net zero I say. But fix the roads, hospitals and schools as well. Everything isn't mutually exclusive, a government should be able to more than one thing at a time, if they can't, boot them out next election.

More akin to what occured in lockdowns in 2020 for COVID. Almost no cars or flights moving about. Can now can see the main road between Inverness and Aberdeen, its a constant stream of cars and lorries in both directions.

It's a tick box exercise for the planner. We did nothing like the plan in the end, and no one cares after planning. Your architect should be able to cut and paste his last one, into your.site plan.

We had an infestation of rodents in 22. I ended up using bait stations, which have worked well. First year we got through about 8kg of poison.

Our April is our best month since recording - about 20% better than any month last year. But no rain, any rain we have had has been a short shower.

Shows you should always check. Cheap product, with expensive repairs required in 10 to 15 years, if you had taken his poor advice. Someone is possibly getting their house built now, with roof membrane as a vapour stop membrane. And the builder will do his next that way also! Doesn't bear thinking about.

So That's small beer on a global or country perspective, tax take in 2024 in UK was about 1,100 billion. It makes money by making companies pay to use it or they get hit by more expensive carbon credit penalties. My last reasonably sized project was £2 billion, payback was in between 8 and 10 months. Project life expectancy 15 years. Two ways to look at emissions. London has huge issues with localised population caused by lorries, ships and cars. Removing those sources of pollution from bad areas, fixes those pollution issues at a local level. Makes no difference on a global scale, but people living in that area can breath better and live more healthy. Carbon capture is a just a slightly bigger version the above. If we look after the smaller stuff that effects us, it's a good thing, not a bad one. You putting 400mm of loft insulation in does nothing for emissions on a global scale, but it reduces your emissions, helps your wallet in the long term. Your next door neighbour doesn't bother, but why should it not stop you doing the right thing. Don't look at things as global this, and global that, we can do things we control, doing the right thing gives a cleaner healthy country.

I was involved in a project a couple of decades ago for Peterhead power station - all CO2 was captured (all flue gas in fact) it would have been process, hydrogen comes out as a waste product (no market for it then, there is now), waste gas stream gets compressed and sent offshore to spent well.

Sort of right but somewhat oversold as heat pumps modulate power down reasonably well in most cases. A house needs a given amount of heat and to a large degree the same kWh of heat is the same for any heat source. The thing that cripples (makes them costly to run) heat pumps is flow temperature. So the ideal is a heat pump heating system designed to a max of a out 40 and no more than 45 degs. The lower the flow temp the less it costs to run.
