If he does have insurance, it may well include a legal advice line that he could call.

I've never come across a particular word for them in the South - I'd just talk about a parapet gable / gable parapet.

Rethinking the mindset for mass retrofit - a provocative idea
Mike replied to JamesPa's topic in Air Source Heat Pumps (ASHP)
It will happen. Technology adoption follows an S curve. The first domestic microwave cost $1295 in 1955 - roughly $14,000 today. The question is how to speed up progress along the curve. It could be by Government mandate, but typically it's by subsidies. Not necessarily UK subsidies - often the UK prefers to wait for other counties to subsidise and develop new technologies, then import them (and then wonder why we don't make them ourselves). See also the development of the wind turbine market in Denmark in the 1980s & 1990s. -
Global warming is in fact entirely natural and has already peaked
Mike replied to ProDave's topic in Boffin's Corner
China's position on coal is confused, but their proportion of electricity generated from coal is declining. And they already generate more from solar and wind than either Europe or the US, and are installing more of both much faster than Europe & the US.

It's climate denialism presented by the Environment Spokesman of the former* minor far-right political party For Britain. *According to the Wikipedia page the party has disbanded, though their website is still up. -
Pipe banging, don't want to have to lift floorboards.
Mike replied to mickespite's topic in General Plumbing
This suggests that @Iceverge's solution is worth a try: Install a water hammer arrester and see if that fixes it. Various inexpensive ones available, such as: https://www.bes.co.uk/catalogsearch/result/?q=hammer+arrester -
Insulated Concrete Slab Garden Office - Questions

It should all be no fines. Yes, pea-shingle should be just shingle - no sand or other fines. -
Insulated Concrete Slab Garden Office - Questions

MOT Type 1 is a specific Government standard for the sub-base of roads, with multiple requirements that must be met. To be precise, the specification is technically now 'Specification for Highway Works (or SHW) Clause 803 Type 1' - the specification was originally written by the Ministry of Transport, hence the snappier 'MOT' is still widely used. Crushed hardcore is just that - it doesn't necessarily meet any specification at all. It could be close in composition to MOT Type 1, or not. MOT Type 1 is frequently specified because there is no doubt that it will perform well long term. If you choose something different, you need to satisfy yourself that it's up to the job. -
Depends what you're trying to achieve. Your spec would exceed building regs (provided you weren't choosing 70mm stud due to the ceiling height / load bearing capacity). However it won't block impact sound - for that you'd need two independent studs - effectively two back-to-back single sided partitions.

Yes, it's not often done domestically, but for the sake of a few pounds it's worthwhile adding a Y-strainer on the incoming water. Ideally add others before each pump and mixer.
-
A few ideas to start with: 1 - You don't have to put anything there. You could just blank them off for possible future use and stick to other light sources - floor & desk lights, for example. 2 - You could loop a flex from them to a light suspended in a more convenient location nearby. As you've chosen Moroccan elsewhere, perhaps something like this one, to shed some interesting patterns Fretwork Moroccan styled pendant? 3 - For the home office (if it's only a home office), then you could indeed choose functional spotlights, either tracked or individual.

Trusses to ridge beam - who to call to design?
Mike replied to Pabbles's topic in Roofing, Tiling & Slating
When I did something similar I just used load tables for rafters and for the glulam beam. Done within the hour. -
Larch or Brick? - a Cladding Dilemma
Mike replied to deancatherine09's topic in New House & Self Build Design
This for me. -
I remember seeing a house in Bristol that someone had stuck stone cladding to - right in the centre of a new brick-build housing estate. Hideous. Think it would have been in the 90s.
-
It also depends on you - or your representative - checking it at the right stages, to identify and remedy the leaks. Don't underestimate the ability of the builders to install it incorrectly. Get the BBA certificates are check that they're being followed. The builder will just go to their regular suppliers and pay what they're invoiced, plus a mark-up to cover their time, effort & profit. If you have the time to shop around, particularly for high value items, you may make savings even if you do have to pay the VAT. Or arrange with your builder that you will identify certain suppliers and they'll buy the products at cost + an agreed markup.

MVHR is Largely Bogus
Mike replied to DavidHughes's topic in Mechanical Ventilation with Heat Recovery (MVHR)
I don't have the EPC software, and a air-change value isn't mentioned in the report, so can't elaborate on what's included in that. However the Fiabishop spreadsheet gives air change options for 4 building standards (5, 3, 1.5, or 0.6 air changes / hour), or a custom figure, in addition to the controlled ventilation of the MVHR system. It also allows you to compare 2 different MVHR units*, or one MVHR unit against regular mechanical ventilation (i.e. kitchen & bathroom extractors). It also allows you to input the m² area, m³ volume, location, expected occupancy, lengths and insulation of the main air supply and extract ducts, whether or not you're using hygrostatic controls, whether or not you intend turning it off in summer (and open and close the windows instead), takes into account the local climate, wind sheltering, orientation, the use (or not) of earth warming tubes (puits Canadian / Provençal, with or without pre-heaters), and a few other factors. The figures I gave above are for 0.6ACH, comparing the Zehender unit with regular mechanical ventilation. *The spreadsheet is pre-loaded with data for 32 MVHR units from 12 manufacturers, with the option to add more entries yourself. So, comparing the Zehnder unit to a Brink Renovent Exellent 300, it forecasts that my energy bills would be €8/year higher. -
Still no for me. I'd only go EWI if the entire street was being done together.
-
No, IWI at the front, maybe EWI at the back and the side.

MVHR is Largely Bogus
Mike replied to DavidHughes's topic in Mechanical Ventilation with Heat Recovery (MVHR)
As noted in my post, this particular apartment is in France. What I'd forgotten is that UK EPCs are still based on a hypothetical predicted fuel cost; in France they are based on primary energy use (kWh/m²/year) & CO2 emissions (kg CO2/m²/year) - the lowest of the two scores determines the rating. I guess the UK may eventually catch up. My French EPC is calculated on a saving of 2,000kWh when using MVHR - too round to be unit-specific. However, the free Fiabishop.com MVHR calculation spreadsheet (in French only) does calculate based on specific models. It forecasts that my Zehnder unit will use approximately 148 kWh to run for the year, and cut space heating by 1,687 kWh, and overall saving of 1,539 kWh. Assuming gas heating, at the current UK average rates of 10.3p/kWh for gas, and 34p/kWh for electricity, that's a saving of £124/year (or £523 with electric space heating). -
A battery powered lamp is another option, but I actually suggested USB-powered :)
-
And a 5th option - a USB powered lamp. Mostly intended for desk use (e.g. https://www.amazon.co.uk/Lepro-Dimmable-Brightness-Powered-Reading/dp/B09XF3HRGW ) but there may well be others if you hunt. Over time there may be more choice as USB PD (Power Delivery) chargers become more common. They can theoretically deliver up to 240W, though I've not seen one over 100W. https://www.usb.org/usb-charger-pd

Have you got any photos of this? I will need lights in the near future for vaulted ceilings. My photo collection is on my main computer, which is currently in storage, however it was something like this (but more atmospheric): https://www.lightingstyles.co.uk/simple-adjustable-low-voltage-tension-wire-lamp
-
You wouldn't do it these days, but 30+ years ago it wasn't uncommon.
-
Forget ceiling downlights - there are more interesting ways to light a room, especially a room with a vaulted ceiling. The last one I built included spotlights suspended from tension wires hung from gable to gable, for example, as well as wall lights.
