I had in my mind roughly 2k per indoor unit, and this seems on the expensive side. The second quote bizarrely adds another unit in the kitchen which when they surveyed said wasn’t necessary!

We currently have two mortgages with our lender for our property, one of which we ported. The ported one is due for remortgaging at the end of the year, and the other in just over 2 years, with the plan to combine at this point.

We are keen to do some home improvements (solar +/- heat pump and AC) which would require taking on some additional debt. We are financially comfortable to do this, but our mortgage is at the top end of what was available to us, I’m concerned additional debt might spook the lender.

Is this an issue for the lender, or is it less important once you’ve purchased the property and have shown to be reliable in making payments?

Would appreciate any views! Thank you
