I'm not sure if this helps, but we bought kitchen cabinets from these people, TKC which is TK Components Ltd. It worked out well for us but might not work for everybody - they were supply only and would not sell direct to us as the client. We had a loose arrangement with a builder, who had an account with them, and had a joiner who installed the kitchen for us on day rates. TKC invoiced the builder (50% discount), we reimbursed this to him and paid the joiner to do the installation. TKC's design service was pretty basic but fine for what we wanted on that job. There were a couple of mistakes and we were happy we had an excellent joiner who could sort things out. The cabinets are fine for what we wanted. Very happy with the end result and the price. We bought the quartz top elsewhere. P.S. Well done mod @jack for sleuthing the conflict of interest with TKC Kitchens.

I bought glass as well as hardware from F.H. Brundle for a balustrade. Their glass was a good price.

I'm a bit concerned that external Venetian blinds will get dirty and dusty and be difficult to clean. Any issues with this? I looked at these external screens at the NSBRC and they look quite interesting https://www.solar-shield.co.uk/microlouvre-screens. You can see through them but they claim to screen out enough to control solar gain.

Hmmm. Food for thought. I plan to self manage and have as little hands on the tools myself as possible. I'm fairly well plugged into a network of good local trades who've worked for me before (not a full self build though) and have told me they will be happy if they're invited back. I have a friend who's a builder and is happy to advise and get me out of trouble. Tricky when you don't know what you don't know though. I've had quotes from four timber frame companies and asked them all the same open question, what will be left for me to do when you leave the site? And I've tried to estimate the value of the different scopes to compare the quotes on a similar basis. I suppose this is what the contingency is for? I'm in Cheshire. I'd appreciate any advice you can share. I'll drop you a DM.

They quoted for 0.15 U value external wall ULTIMA 90/50 (TW55/TW55) system, factory fit insulation between the studs, a VCL, a secondary insulation layer across the studs, and a service void batten. They also offer an upgrade to 0.12 U value external wall - ULTIMA 140/50 (TW55/TW55), which we would take if we go with Potton. The leak tightness they "target" is the same regardless. I agree, 5 is not sufficient. They said we could make the target 3, but I'd have to check my notes whether they proposed a charge for that.
-
I have a quote from Potton (but we're still wrestling with planning🫤) which says "You have not advised your requirement so we will be targeting 5. We will achieve this air tightness through the external walls. Air tightness of the overall structure is a combined responsibility between the principal contractor and all trades". Actually I have advised I want better than this and they are prepared to "target" 3. Did you have any expectations about what airtightness you'd get from them?

Catch up! He was talking about condenser dryers 😀. ... about which I didn't know much until this voyage of discovery.
-
Well, I think I know that you didn't read my post. I was talking about condenser dryers. The ~ 2.5 kW heat from a condenser dryer all ends up in the room .... well tbh all the heat from your heat pump dryer's compressor motor ends up in your room as well, however much that is 😉.
-
Indeed, I understood the heat exchanger bit, but I was confused about what air went where! The room air just blows over the condenser and then goes straight back out into the room. If your tumble dryer has a 2.5 kW heater, all the 2.5 kW ends up in your house which is maybe a good thing in winter. If you can move that heat into the rest of the house, you'll save on heating bills and if it reduces the temperature of your utility room, the condenser will work better and you'll dry your clothes faster. The guy in the linked YouTube video isn't a fan of HP dryers and agrees with what @Nickfromwales says about drying times ... link. Sorry if this hijacked the thread. I know a lot more about tumble dryers now 😀.
-
Interesting. I wasn't sure what would be the cold surface the moist air was condensed against. Just did some Googling and they have a heat exchanger where the hot moist air out of the dryer exchanges heat against the colder incoming air from the room. Thinking about the heat and material balance around it - since the condenser is being cooled by incoming air from the room, there must be air going back out into the room which has got to be hotter and moister than what went in. Maybe that hot air is OK in winter but not what you want in the summer if you're concerned about over heating? And once that warm moist air coming out of the dryer cools down, do you get condensation in the house - maybe not a problem in a typical British drafty house but more of an issue in an air tight self build? @Nickfromwales says that HP dryers have long drying times, that must be simply to do with the size of heat pump they use. In principle, you should be able to condense more water out of the air on the cold side of a heat pump and sent it back into the dryer with less moisture still in it. Or is there a design problem balancing the size of the cooling/condensing and heating sides of the heat pump? I'm still a bit confused!
-
Am I right in thinking that if your tumble dryer is not a heat pump one, it needs a vent to the outside? If so, is that a problem for achieving good structural leak tightness?
-
I'm not familiar with one of these, but are there other hazards you need to address? Asbestos? Electricity supply isolation? Gas supply isolation?

Looks like lots of current and ex landlords on here. I've thought about it but largely through inertia never got round to it ... but is it a good investment? I've often wondered, if you put all of the expenses, rental incomes and capital gain into a discounted cash flow, what annualised return does it yield? Investing in a plain Jane MSCI World Index ETF over the last 10 years would have yielded an annualised before tax 11.7%, with none of the hassle.

Not caused by renewables or lack of inertia.... "The ultimate cause of the peninsular electrical zero on April 28th was a phenomenon of overvoltages in the form of a "chain reaction" in which high voltages cause generation disconnections, which in turn causes new increases in voltage and thus new disconnections, and so on. This phenomenon was preceded by large amplitude voltage variations in short periods of time throughout the morning." "Therefore, it is highly probable that, in a scenario of greater inertia and therefore a slowing down of the frequency drop, the "surge wave" would have caused the "cascade effect" in any case, causing a significant part of the generation to drop and thus overcoming the response capacity of the underfrequency protections.."

Good to know. Thanks for sharing. And this PCC is issued by an FRCS, so a member of one of the approved professional bodies.
-
The professional requirements are listed under 6.7.4 here. But maybe the people CMLC sends out are members of one of these professional bodies?
-
@nod your screenshot with PCC at the top suggests it's a Professional Consultant Certificate and not a Structural Warranty. The post linked below discussed the difference and that a PCC might not be accepted by a lender, which if it were true would make the house hard to sell. On the other hand, there are comments in that thread that some lenders don't require either. I'm sure you looked into this. What are your thoughts?

I'm at a similar point with quotes from four timber frame companies but still wrestling with planning. I got quotes from Potton, Frame Technologies, Fleming and MBC. They all quote on different scopes so I made myself a spreadsheet to make sure I had a number against every element. Potton were the cheapest, Frame Technologies were +21%, Fleming were + 23% and MBC were + 35%. I got a price from MBC for their proprietary insulated raft foundation but did't include that in the cost comparison - I'm sure it's a high performing foundation but I wasn't sure it was value for money. Some of them offer an insulation package which includes the slab so I accounted for that in the comparison. If I include the MBC insulated slab foundation in the comparison and assume a strip foundation for the others at half the price, the numbers come out still with Potton the cheapest, Frame Technologies +17%, Fleming +19% and MBC +45%. Another aspect to consider is what professional services they can provide - SAP calculation, BR drawings, `CDM principal designer etc. As always, the cheapest price might not be the best value. @Nickfromwales is right, with MBC you have fewer interfaces to manage, and there's value in that.

It's not really a survey, although that's what they call it. It's a consultation. It's asking for input on several of the concerns about BNG which have been raised on here, for example getting rid of the self build exemption, which LAs are implementing via an onerous unilateral undertaking, and replacing it with an exemption based on the size of the plot - they propose 0.1 ha. I support that, but think the threshold needs to be more than 0.1 ha. Definitely worth reading through and responding.

BNG de minimis exemption for self build in garden
LnP replied to Fi and J's topic in Planning Permission
So you're splitting off a building plot from the garden of an existing house and leaving the existing house. The question is simply whether the area habitat which will be lost when you build the new house will be less than 25 m2 . Crazy paving is not habitat and neither is unvegitated land, but the overgrown bushes might be. If you're going to make a de minimis claim, I think your LA is probably going to want that to be supported by a report from a competent ecologist. I suggest either getting a recommendation from an independent planning consultant or phoning round a few and discussing you case with them. If you're a bit marginal on the <25 m2 , you might get a feel for whether a bit of bush clearance might help. -
BNG de minimis exemption for self build in garden
LnP replied to Fi and J's topic in Planning Permission
I'm no expert, but my understanding .... CIL and BNG are completely different obligations, but the link is that they are both enforced by the LA under section 106 of the 1990 Town & Country Planning Act. And the BNG UU explicitly states, "This Deed is a local land charge and shall be registered as such by the Council". And there's no CIL where I am. -
BNG de minimis exemption for self build in garden
LnP replied to Fi and J's topic in Planning Permission
No. The way it works is that you have to start by working out the "pre-development diversity value". If you've done work on the land since 30th January 2020, you have to go back to the diversity value before you did the work. It's in The Environment Act Schedule 14, Part 1, paragraph 6. I can imagine though that in some circumstances it might be difficult for the LA to establish how the land was, but you can expect them to look e.g. at historical Google Earth images. -

BNG de minimis exemption for self build in garden
LnP replied to Fi and J's topic in Planning Permission
This is not correct in my experience. Where did you get this? Is there an LA doing it like this? Don't mean to sound rude, just curious. In my LA, and the Dorset one which was posted elsewhere on BH, when you sign the UU, you are entering into a covenant that you will be the first occupier and that you will not sell the house for 3 years from the date of your first occupation. This is enforced by the deed, i.e. the UU, being a local land charge and registered as such by the Council - you can't sell your house until either the LA remove the charge or it expires. Obviously this is a problem for lenders as if the owner defaults on the loan, they can't dispose of the house to recover their money. None of this is required by the regulations. It's regulatory over reach by the LAs. -
BNG de minimis exemption for self build in garden
LnP replied to Fi and J's topic in Planning Permission
There are several posts about this on here already. Google search Buildhub to find them. We're demolishing an existing building and the new build will be mostly either over the existing foot print or over ground which is unvegitated. The area habitat which will be affected is currently lawn and less than 25 m2 . We found an ecologist who wrote a report for us supporting a de minimis claim which we've included with our application. These judgements and answers to the questions you raised can be a bit subjective. Some ecologists are running BNG points banks and I can't help thinking they might be more inclined to support assessments where they can sell points, i.e. less interested in a de minimis claim. The ecologist we used wasn't doing that. He was recommended by our planning consultant. The report cost £200. We're keeping our fingers crossed the LA ecologist agrees. I'm wondering how long it will be until somebody notices that BNG for self builders is unjust and a mess and does something about it.
