I would think you have probably already done this but it has worked for me on some of these issues where you think 'I would just like to know someone has done this before, and you can do it relatively easily' Have you tried searching on Youtube, Instagram and Facebook for tutorials of any kind, sometimes putting wildly different search criteria works well. Sorry if I am suggesting the obvious, just may be worth trying first.

Hiya, that looks like the most likely path forward. Thank you for that link that is probably how i’lll end up insulating under the floor.

To tell you the truth when you do the maths on ASHP they really really don't stack up, thy'll only really be worth it if gas prices soar and electricity comes down a lot, I am looking into Solar Panels though so that may be game changer, but those added costs for that even when I take everything at best case don't stack up, for cost, comfort, usability or maintenance. It's a shame really because the best outcome after all the insulation would be a hybrid system of ASHP and Combi boiler but government say no.

Yes, As for MVRH's I understand the ' only through the lens of money ' and I think they are worth it for damp prevention and generally better feel to the atmosphere in the property, and you are pushing an open door but I read unless the house is airtight don't bother, if you think otherwise I would be interested to know. As for ASHP's I have come to the conclusion of they are ok! Should be called 'ELECTRIC' Air source heat pumps because no one ever seems to get the running costs they were promised by the designer, they aren't any good if you need to place the fan unit anywhere near a neighbours house and they really need a boiler for back up when the weather gets colder. I spoke to someone who had UFH throughout downstairs and he said at best he would call it, low background ambience not heating the room, but I did ask if he left it on permanently like they advise and he kinda fudged the answer. Soo at this moment I think yes definitely to EPS beads cavity wall insulation (upon further investigation) Yes definitely to MVRH and like you said take it on a room by room basis. Any other ideas I am all ears or eyes as it's an internet forum. I have inherited 300mm loft insulation but I think I will insulate between roof rafters as well and definitely insulate with floor with PIR, I have 4"joists on the ground floor and I will have a company we have used before advise me on that underfloor insulation but will probably be 50mm PIR boar and then 50mm their pipe trays with 50mm insulation which gives me 100mm on ground floor.

Good morning Iceverge, yes I have. I have been involved in small refurbs where MVHR has been installed and various heat recovery units have been used and they worked amazingly well to combat damp and even made the properties feel warmer, but they were flats, I am told that if you can’t get the property sealed and pressure tested it’s not worth it. I think getting this 1950 built house to the level required would be almost impossible. i am open and willing to look into every single suggestion, I have even looked into waste water heat recovery units. i just want to see a decent return and improvement. I keep looking at Air source heat pumps but I have spoken to quite a few people with experience in them and it’s all disappointing! Seems they only work if you keep your boiler as back up, then you don’t get the grant. Please send me a list and I’ll research it all.

Front and back pretty much identical, the depth of property is 6m deep, going to have new front door but windows will stay.

Hi 1, Yes I can attach photos, no problem. 2, We are redoing all the interior, but some rooms don't have space to add internal insulation 3, Yes I will rewire the whole house and 90% of the plumbing 4, I can do that closer to start of main works. 5, I will have to get the exterior patched up and painted anyway by the end of the job. cracks filled and smartened and painted I will carry out but the outside insulation will be done by a contractor. I just wanted to know, as most insulation gains are gained from the first part of insulating and after that the gains decrease, wether once I had insulated the cavity, all be it if it's only 50mm would I really benefit from exterior insulation.

13.5" Wall, exterior walls including plaster on the inside and render on the outside, I assumed 2 walls of 4" wide bricks and 1.5" for the plaster and render and bobs your uncle, cavities are normally between 100mm to 150mm, on a 1950's built house there not always perfect so I was edging on the side of smaller to see the numbers. I haven't actually knocked one open yet so it may all change at that moment. Would you think I would benefit greatly from outside insulation after cavity wall insulation I don't think so. Want to try and be as green/environmentally friendly as my budget will allow really

Hi I just wanted to introduce myself and ask a question. I was originally a gas engineer started with BG as an apprentice back in 1987, I have worked in the building /property industry ever since I now have my own property management company so if I can help out on any queries I will. I have my first question, I recently moved to a conservation area, my property comes under article 4 but where we are is split into 2 tiers and ours is the lesser tier so I can make alterations to the property within reason but need to keep the character of the area. Hardly any work as been done on the property since it was built except for 2 badly built extensions that need tidying up, My question is my first job now I have made the building watertight is insulation, I have 4"cavity walls which I will get insulated but is there a preferred insulation for cavity walls and would I benefit greatly from exterior insulation (would exterior insulation be worth it?) I have to repair and decorate the exterior anyway but don't want to go to the expense of exterior insulation if it's not worth it. the property is detached.
