Andehh

Insulate the pipes thoroughly!

How's the rest of the house? 150mm to 200mm is a big step, for disproportionate improvement.... Especially if rest of the house is lacking!

Considered a slate cladding type? Small tiles, more grout lines, better able to breath and would match your overall colour scheme?

Check that cavity as well, how much rubble is in there? Beyond where you have rightly taken out a brick to check. All being said, this can be fixed!

This! And keep an eye on the quality of the work. You should have drawings that stipulate the amount if insulation to be installed? They form part of the contract of work needed, for payment to be made.

Have you paid the full balence? How complete is the work? . Cavity wall insulation can be retrofitted, and based in the imagine you've got of the roof pushing rockwool down the void with a broom is an option.

They are very prone to leak, so consider a decent slope for water run off and seal it all very thoroughly!

Samsung for me! Ever heard of similar with Samsung?

I got an identical email! I'm torn, but as they say their records say it needs doing in September 2025 it's one I will delay! Have to admit these servicing costs really add up! £250 + for electric gate (lots of greasing, fair enough) £90 + for double garage door (it sticks occasionally and needs adjusting under warranty so probably need to pay it to keep up with it) £250 for ASHP, questionable but warranty!? Air con units another one, can't remember but I've got one free service remaining!

We have porcelain tiles, and they don't get slippy.... But I do brush them down after heavy rain to keep them looking good! 😁 In the summer fairy up liquid, and a large broom every few weeks... Because they match the kitchen tiles and we have large sliders... having the same tile inside and our a flush threshold.. looks ace! Just a shame it's also a massive (expletive deleted)ing cold bridge because I took my eye off the build for one minute.... DAMN!

2 bricks ideally. I'd possibly compromise that with an acro drain and render covering above DPC. Not best practise, but personal preference.

We've had great service from https://cts-hvac.co.uk/

Our MVHR vents come through the same roof as our wood burner insulated chimney. Probably 3m horizontal and 2.5m vertical for seperation? Rarely do we get wood smoke pulled through, but it does happen when the prevailing wind is just right!

White render, black aluminium windows doors and the slate cladding was the style we went with! The finished off with some nice western red cedar cladding (I think it's called? Expensive stuff!)

Big batteries also last longer then most people realise providing temp extremes and charge speeds aren't abused!!
