Apologies, I have just posted incorrectly in a related oider thread and repeat here for your information

I have no personal experience of of robotic lawn mowers but today I played golf at my club in Spain and noticed they we commissioning a couple of new devices on the practice ground, when I was warming up before playing. I knew we had been using a robotic ball collection machine for past year or so, and remembered your post, so I went to look at them and talked briefly to the company representative. I took a few photos of the robotic lawn mower and its sister robotic ball collector. together with their mother station, which attach. The golf club is Aloha Golf Club, a well known private members club, which hosted the LEGENDS Tour about a month ago, and has hosted the European Tour (mens and ladies) in the past. The practice is over 250yards long and an average of 100 yards wide. It is also has steep slopes. I went to the 1st Tee and one of the guys I was playing with had notice me taking photos. He lives in Aberdeen and told he has exactly the same robots at home and he showed me the app on his phone that he uses to control it. He also told me he is involved with a local football club and they have installed the same robots for maintenance of their pitches, allowing them to release a groundsmen. He spoke highly of this device.... Finally, he told me that another Aloha member has two of these same robots at his home on Scotland.

No, I my mistake - I wasn't concentrating and missed the 4x .....ugh Apologies

Wet and Forget is similar to this and also works like magic on render and patios and it may be cheaper. Costco seem to do the best deals on this https://www.costco.co.uk/Grocery-Household/Cleaning-Laundry-Products/Cleaning-Products/Wet-Forget-Concentrate-Mould-Lichen-and-Algae-Remover-5-Litre/p/128234 You can get a Gardena Backpack sprayer withe extended lance set that we have used to spray up to our gutter relatiively easy. https://www.gardena.com/uk/products/tree-shrub-care/pressure-sprayers/backpack-sprayer-12-l/970477401.html

Commiserations... We had a similar problem when we demolished a house in 2015. Everything was going so well, when the resuts of tests on the white render came back from the lab. The whole of 1930 house was covered in render which had to be removed by hand and removed from site by a team in white suits and protective gear - it gave a bit of a scare to the neighbours. It doubled the cost of demolition from £10,000 to £20,000.

This may help you recover VAT from contractors. There is a more useful information in the original thread

We live in Sunningdale on a main road and none of the houses on my postcode and adjacent area have house numbers, only house names. We're not in a rural area. We've never had any issues getting insuraance, buildings or motor......

We used Sweet Chestnut for our build in 2015/16. There was post on the subject on April 2022 - see attached. I can take some current photos, if useful?

I helped my son and daughter in law with to source DGU's. They live in the New Forest so I can't recommend a supplier. However, I found that most traditional, and usually well established, glaziers/glazing companies in that area were very capable of supplying and installing replacement DGU's in existing window frames. They were also competitive and made a site visit and measure before finalising quotations. They also installed, after removing the old blown DGU's and removed all the old materials. the companies who supply and install replacement windows were only interested selling complete new windows/frames or supplying DGU'S that were not specified for the existing windows, because they only supplied DGU's which were suitable for modern plastic frames formats (too thick for the existing frames).

I have PAUL Novus 450 MVHR for a 5 bed house. I don't live a a city environment but in a semi-rural environment but near to a busy road. PAUL recommend changing the filters every 3 - 6 months. They are synthetic material/paper filters that cannot be cleaned, so have to be replaced. I change the inlet F7 filter every 4 months approximately as they get very dirty - see photo I change the G4 exhaust filter every 2 years or so

+1 to this but and you seem to have covered most of the key points. The big question/issue for me is the detailed routing of the ducts, particularly downstairs, in locations where you haven't negotiated "permission" to reduce ceiling height. There is still a lot of investigation and detailed work to be done to ensure that you are able to make penetrations in floor joists without compromising structural integrity BEFORE you start installation.

Well done! It's a critical and often overlooked detail.

Looking good I can see that you have made significant penetrations in your I-joists. Holes may be cut in I -beams but only in accordance with manufacturer's guidelines/rules - see typical guidelines at https://elliotts.uk/ideas-and-advice/i-joist-faqs Have these penetrations been checked by your SE for each specific location to see if acceptable ?

Most gas boilers specifically prohibit the use of "artificially softened" to fill central heating systems, which why the heating system fill-point should be from the mains supply I seem to remember it caused problems with the heat exchangers? I attach the relevant page from WB Greenstar system boiler, which is now 8 years old. Maybe not problem with ASHP and modern UFH systems and it should be checked

We only have hard water to the kitchen tap and outside tap. Use softened water in bathrooms for brushing teeth.
