A2A Heat Pump / Air Con

As with the 29/5/2025 changes I understand that it's possible to install air con / A2A heat pump without planning permission?
We don't have radiators / gas at the property and air to water heat pump costs even after grant were just too high, hence I was thinking of getting A2A mostly for heating and casual 5-7 days a year for cooling.
Could someone just answer my questions?
1. I got a quote around £2000 for Daikin 3.5kW - and one indoor unit - it doesn't require planning permission, right? (far away from neighbours, no conservative area, detached house..)
2. A bit random, but is it possible to get MCS certificate for A2A pump?
I'm just double checking what sales people said and as these are new rules hard to find good info online.
Thank you

I had a Midea 3.5 plus one indoor fitted for £1500 a year ago.
PP no longer needed as you said, not sure about MCS.1 -
Ok I think I'll answer myself regarding MCS, looks like there are some ongoing things but not available yet, maybe by end of the year.0

Hi John, purely for comparison purposes, I've looked at the company that have supplied and installed a 3.5kW unit for me. Actually same company have installed 2 for me,
looks like starting price of around £707 for unit, and £600* for install.
*£595 for units up to 4.1kW, and VAT free if supplied and installed by same company.
Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.
For general PV advice please see the PV FAQ thread on the Green & Ethical Board.1
