Advice on insulation, heating, ventilation

[HouseRenoQ]

I’m going to be renovating our small semi back to brick and want to insulate and move from oil heating to a heat pump and underfloor heating.
also interested in heat recovery ventilation systems, air quality is very important to me.

The oil boiler and tank need replacing soon, and due to a small garden i want the tank gone/to come off oil. Also for environmental reasons.
We’re willing to spend the time and money to make it work in this house.

Does anyone know of any advice services or forums for this? It feels like a total minefield and don’t want to fuck my house up quite frankly.
I’ve already found out we can’t have cavity wall insulation due to driving rain/exposed aspect, but am still getting advice to do this.

Anyone got any advice or direction of where to ask?

If you go back to brick you have to insulate to modern standards and need building regs sign off (if you want to do it by the book ).
How old is the house? That will impact what sort of insulation is best as older houses tend to need to breathe a bit and moisture permiability needs to be taken into account.

What age house?
The energy saving trust website is a place to start.

Depending on income and where you are there may be grants for insulation and installing a heat pump. Maybe solar too.
External insulation might be an option too.

House is around 1900 and has cavity walls. It’s brick built and want to keep that on the outside as has interesting detail.
it will have a modern extension we were planning to insulate really well. The old part of the house is 2 rooms downstairs and 3 up. We’ll be adding a new kitchen/diner/utility/loo in the extension.

The old part has half concrete floor downstairs and half (rotting) timer suspended floor. We know we need to do something about the timber half anyway.

looking at wunderfloor heating up and downstairs. Upstairs would really benefit from no radiators as the bedrooms are tight anyway.

The rotting timber worries me. Why is it rotting? In a house that age, there is probably a slate damp proof course, which are pretty much indestructible so damp joists suggests that maybe the external ground level is breaching the damp proof course? Or there is a leak somewhere?

Of you insulate before you fix the damp issue , or at least identify what is causing it, you could end up making the problem a lot worse.

If you can get to Swindon, I recommend heading to this show: https://www.nsbrc.co.uk/whats-on/our-events/
Lots of help and companies to see there.
