My advice is to try find a similar planning application and see what they provided. The condition says you need to provide a "Construction Ecological Management Plan (CEcMP)" so I would try and find a document with that title on the portal and read it. If there is anything irrelevant to your site edit it out. Make sure you aren't committing yourself to anything expensive etc. I'm pretty sure that a CEcMP will be all about protecting wild life during construction, whereas a "Biodiversity net gain (BNG)" is more about ensuring your planning application as a whole improves Biodiversity. I would stick with the former until they insist on the latter.

Will it be a flat roof and which way will it slope? Normally any overhang and or gutter will determine the gap as much as anything. I don't think 50mm will be enough for them to properly fix/finish the edge of roofing felt. I would ask about this detail and future maintenance.

If you assume the UFH loop pump and ashp pump have same flow rate then no water flows through the short circuit. If there is any difference in flow rate it will go through the short.

It was ok as it happens. Just landed in Delhi. Probably best to let you get back on topic.

Technically I don't think you don't need PP for a van for building workers to live in. So if all occupants can claim to be doing at least some work on the house you should be ok. No children obviously. I believe this even extends to a van on neighbouring land. I'm travelling at moment so can't easily quote a source but it should be possible to find it in the GPDO somewhere. Edit: The menu on my flight includes "Fluffy egg preparation" I guess that's an omelette then.

When we built the regs required a level entry to meet part M of the building regs. Basicaloy followed this example from the web.

Non standard construction can sometimes be hard to get a mortgage on.

I thought what you want isn't allowed in building regs? Don't they have to be staggered in height or is that only when one side is smaller than the other?

The effectiveness of insulation depends mostly on.. a) The thermal conductivity of the raw material it's made from. Lower is better. b) The thickness. Pure Aerogel has the lowest thermal conductivity but in it's raw form it's very fragile and expensive so it's not normally used except perhaps on spacecraft. Usually it's in a different form like a blanket and these have a higher thermal conductivity. Beware sellers quoting the thermal conductivity of raw Aerogel in adverts. Compare with the actual specification of the prouct. Post the numbers including the units of any product you are looking at and someone might be able to comment. Next best is probably something like a PIR based foil covered foam. Typical all insulation products have thermal conductivities that vary by perhaps 30% so none can be 1/10 the thickness of another and have the same performance. Beware some manufacturers quote U-values for their product when installed with an air gap. Anyone can make their product look better by requiring an air gap. I'm currently on a train in India so might not be able to reply. Family are at home so it's not a risk me posting this.

There is a slight risk of water crossing the cavity via insulation but the grey coated EPS systems seem to be least prone. If the outside is rendered the risk reduced to virtually nil if it's kept in good condition.

If you simply converted the whole drawing (including scale bar) from .pdf to jpeg and then back again any unwanted scaling should affect both the building and the scale bar equally. To get such a large discrepancy either it was always wrong or you magnified the building and scale bar differently? Sometimes you get can get this issue if you accidentally scale x and y differently. For example by doing "fit to page" without "preserve aspect ratio set" when printing? Can happen when printing on different size paper or landscape Vs portrait.

I feel for you. Our Planning Officer went silent for a similar period and we eventually found out he had quit his job. Same happened with the conservation officer a few months later. Literally had to wait for them to hire a new one. I'm afraid I can't suggest any ways to really speed them up other than to write an point out the deadline. Remember I think your deadline to appeal for non determination is 6 months but from when I don't recall.

I'm glad you explained what it was. For a moment there I wondered what you were going to 3D print with soft flexible (TPU) pink (coral) filament.

Is that the exact wording they used? It appears to confuse the max depth and max area rules in one sentence. There are a bunch of rules.. https://www.gov.uk/government/publications/permitted-development-rights-for-householders-technical-guidance But they seem to be confusing these two... "line of building"... That could be an issue if already extended. It's to prevent you adding one small extension after another to get a really massive house without permission. "area"... . That's only normally an issue if you have a large house on a small plot. Perhaps you do run foul of both.

Perhaps find another planning application with same condition in your area and see what they wrote.

Our crew hung the doors then took them down to oil them on trestles.

Use a credit card (not debit) for the consumer protection?

Toolstation have several pumps in that range. They have a 2 bar twin for under £200. So it looks like you're only saving the installation cost. What's the current pump? Do they still make it. If so that's worth considering as all the pipes should line up.

Not me, I had to google them. The website I saw said they are 12 Watt. That's not a lot of power. The few conventional pumps I've looked at have been over 100W per pipe. I don't think there is any possibility of them having similar performance because even if their design was 100% efficient (12W in and 12W out) the conventional pump would have to have an efficiency of less than 12% to have the same output (100W in but only 12W out).

Yes that's because a bungalow loft conversion normally results in a two storey house where as most loft conversions result in a three story house. So the rules for a bungalow loft conversion are similar to that of a two storey house without loft conversion. They typically only requires interlinked alarms. It's actually the height that matters not the number of floors but the effect is the same.

I'm not sure if there are regulations that require you to do more than just replace the boiler. Grant still make External oil boilers. Price of the boiler alone on the Internet appears to r £1800 to $3500 is depending on size. She should get several quotes.

One possibility might be to use a small SSR to switch the coil of a relay that has a 230VAC coil. No DC power needed at the relay. SSR gives you the isolation. Main problem with ideas like this is that it's a home brew solution an electrician might hesitate to use.

I think thats unlikely to be a problem. We've had a negligible effect on O2 levels in the atmosphere by burning fossil fuels. Even the CO2 produced is only such a problem because the greenhouse effect is very sensitive to CO2 levels. I'm more concerned about the effect Hydrogen has. I think Hydrogen is a greenhouse gas so the cumulative effect of leaks might be an issue.

Isn't that what happens now when we burn coal, oil etc.

You can get a kit from screwfix/toolstation to do the test yourself before the BCO comes to witness it. It consists of a 110mm plug with a rubber hose and a bulb you squeese by hand to pressurise the pipe and a pressure gauge. You lift an inspection chamber and insert the plug, pump it up and check it maintains pressure on the gauge. The pressure test is very low pressure, typically only a few inches of water as that's all you have in the traps to resist it. Worth doing before the BCO comes so you can fix any issues. I forgot to put water in the washing machine trap. Lot of head scratching with the BCO present wasn't good for the nerves.
