I can PM you Gordon Lewis’s number if you like? He does the majority of MBCs cellulose work. Maybe you can get him to undertake the whole job, as he’s capable of cutting into and reinstating the airtight layers.

I’ve been very busy sorry, and it’s a complex situation so I’ve not bothered giving you bits of answers in my spare time as it would be of little value. I’ll reply asap, and I suggest you hold off doing anything until you fully understand all the options, actions and consequences. Whoever is advising you currently needs to be shown the door though.

Find some sample images of houses with the same windows in that you are considering, then send the questions and ask directly. Often depends which way the wind is blowing, unfortunately.

You're not alone in getting poor advice. For someone to recommend what I assume is through wall MVHR in any house that's not designed to compliment or benefit from it, is just bonkers. This isn't a dig btw, just another example of the nuts advice handed out by 'professionals' who just don't have a single bloody clue. Borderline embarrassing for them tbh. Take the replies given here with a spoonful of sugar, we're a good crowd and are only well-intentioned We just get frustrated seeing good people being given shit advice and having to pay the muppets for it. Keep posting here, and you can get a good end result. Whoever said that a through wall MVHR unit should replace the adventitious airflow to the WBS whilst your cooking is extracted needs a poke in the left eye, followed by one to the right. Such unqualified tripe is hard to hear without a coarse comeback, sorry.

If that side of the house is "out of whack" then you can only build up the internal side and mask it, leaving the wonky stuff only visible outside; assuming the building is out of whack vs the plate having splayed outwards?

Decent crowd on the current project I'm consulting on, have asked if they will service your area, but they defo travel. I'll PM you if/when they respond.

Yup. Simple, effective, and boatloads of DHW on tap with a...... Don't go plated, just have the instant DHW coil in there and it's deliciously simple. Gives the boiler somewhere to release its anger for the requisite full long burns that oil needs. Low cost? Buy everything second hand and strap it together with pushit pipework. Use copper for the primary stuff immediately off the boiler / to the TS.

And here's where the fabric won't be saved. The things will just refuse to be extinguished for a very long time, so the fire brigade will be pumping foam or powder, or CO2 in, and then have to do so with copious amounts, retreat, repeat, and so on. Too many manufacturer sponsored YT videos showing how 'easily' these 'silly little fires' can be extinguished with a cup of tea in the other hand. Utter bollocks. I've punctured lipo's that we use for racing RC cars, and the amount of anger stored in a box the size of a cooks matchbox is mind-blowing (eg run away and come back in 30 mins to see if it's calmed down yet). When we raced in community centres or leisure centres etc they were adamant that no lipos should be charged indoors at any time whatsoever. Some charged in their cars, outdoors in the carpark, and some cars went up in flames. The facts dictate that these are minimal risk, so attempting to contain this type of fire inside a residence is a bit pointless; if it goes nuclear, feck all will save the building, you'll just have more time to wait for the fire brigade to smash the cupboard to bits and pump your house full of whatever they choose to use to attack the damn thing. Attics are obviously now deemed the worst place to put one, as that's the highest point for the devastation to then drop through the house / into, toxic crap and all; and fire fighters won't be taking their shoes off to come into your house and ascend into the attic space to then unleash hell (of a lot of water or whatever else).

You'll be saying the same thing in 2030.....

You need new plumbers!!!!!!! Have you asked your insurance company if you're covered for this? You need someone who will be proactive here, and cut the studwork out in 6" sections so the screws for the rear wall plasterboard will pull out without hurting the rear wall, IF you want to retain just the plasterboard to avoid decoration? Again, insurance should cover this and the entire wall coming out, decoration, everything. It's dogshit lazy plumbing. Is the shower valve being replaced?

Spread of what exactly? Flames which are in the immediate vicinity, or the enormous amount of toxic fumes given off? The occupants will be killed by smoke / fumes probably at least 30-60 mins before being 'burned' to death. The extra layer of PB / other FR or intumescent material will just save the fabric of the build, and have zero whatsoever to add to the preservation of life. HMO or multi-level dwellings consider the preservation of the fabric, so fire-fighters can have safe access to rescue those on 2nd floors and above, but in a typical domestic residence you just "get out, and stay out"; this is preserved by the standard required by b regs for the obligatory 30 mins. After 30 mins in house fire, the last thing on your mind will be pondering about if the surrounding material can cope with another 90 minutes of utter hell. It boggles my mind that folk have such low comprehension of what this type of fire would do to the survivable interior of a family home. You'll have 5-10 mins max to evacuate, and at 120 mins your family members will be looking into your will to see what goodies you've bestowed.

120 mins is barking mad tbf. If this is inside a domestic residence and the battery(ies) go up in flames, after 15-30 mins anyone near it would be gasping their last ever gulps of air. Early detection and a robust plan to GTFO is all you’ll have for a choice. Attempting to tackle it would require halon or CO2, but in an enclosed plant room that’ll kill you too. If these go up in flames, grab the cat and get out quick. The automatic fire suppression demos are all lovely, but unless it’s a bloody huge reservoir then these just won’t have the legs to keep a terminally ill battery from showing you exactly what it’s capable of.

I’m up against this constantly. My attempts to steer folk away from expensive and time consuming misadventures is often rebuffed at first, then it’s an 11th hr dash to douse the flames with dampened £50 notes.

Your issue will be the lower flashing, and how close you can take that to the gutter.

Current client has looked into this and we spoke in depth about what's "coming next" for the regs surrounding domestic battery locations. Attics are apparently getting removed from the acceptable list, largely due to the logistics of fighting a fire up an attic; eg not having a fire-fighter getting into such a compromised position to fight what is a bloody horrible fire to extinguish. I always design electrical systems to have multi-sensor smoke & heat detection in all plant locations, and I always run a 3-core to the garage if it's quite near to the house as an early warning of a fire in the garage, to give the occupants an opportunity to tackle it before it became fully involved. I also put "locate / test / hush" buttons, positioned strategically, where someone woken by the omni-directional wailing of the smoke detectors can press "locate". This silences every detector except the one which has been triggered, so if in plant or attic or garage etc you can go straight to the source of the smoke / fire vs searching every room in the house in a panic. Not many people put the TD up the attic though, lol.

Red flags galore......good advice!

I guess not!!!!!!! #anyone??

Deliciously simple, but this has to always be the absolute last resort. I don't make the man-rules, but I do wish I made headache tablets.

£35 if you buy my welsh crude, and can accept the smell of cod coming from it...........

Wise words, a lot of people forget.

Extend the trough into a deeper sump, and whack some pumps in!?! We've been self-building for a long time people........ You need a rocket firing up the back end Get stuck in and crack on; there's no free lunches, and the sooner you're not sat in the wings 'considering things' the sooner you'll be living in it

They’re more likely to run out of things to fire at ‘the enemy’, at the rate that they’re going through munitions.

I hope nobody goes and buys up all the loo rolls again……

@Nestor fyi I’ve asked, and the aeration is defo 34/7/365, and the IPS pumps out effluent based on the levels in the tank. So the question is, does the PCB control the effluent pumping to keep the levels properly managed. If so, this can’t be bypassed and needs fixing asap. If it’s been full of snow which then melted then I assume the PCB is a write off. Time to fit a new PCB and screw the cover on properly / provide better cover from the weather, and let it do its thing.

Why not run for 15 mins every hour or 30 mins every other hour etc?
