Got planning permission next steps

sea12

Hi. Long time lurker but first time poster in this forum. Git planning permission for 2590sq ft house just after Xmas.
Now the arch is doing up the detailed construction drawings but is asking about what type of Windows I want, heating system, heat recovery etc so he can show the energy efficiency rating of a house to the council inadvance of commencement notice.

Is there somewhere that explains all this process as don't want to get them done up and then it's more expensive than mortgage will facilitate?
Thanks inadvance for any replies

What the architect is doing is assessing what speciation you need to comply with building regulations. This will then be submitted to the Council as part of the commencement notice application, along with building regulation compliant drawings.

Complying with building regulations is the absolute minimum standard and is non negotiable. There are of course different specifications that will comply and that's up to you to discuss with your architect.

If you cannot finance it then you might have look at alternative designs, finishes, sizes etc

Ok thanks for reply. Yes was just trying to understand the process. The heating system is the biggest cost. He was advocating underfloor heating but I've heard mixed reviews. Does anyone have a good source for me to read the different options in underfloor heating

Best thing you can do is speak to people who have built houses in the last couple of years and ask their experiences. If you don't know anyone, your architect should be able to point you in the right direction.

We have underfloor heating, and find it great, but there are a lot of variables like level of insulation, heating system, glazing, airtightness, concrete slab on 1st floor etc. so you're better to get the full picture.

Everything is linked.

There's no point just discussing under floor heating without knowing where the heat is coming from ie a heat pump, oil / gas boiler, wood burner etc.

Heat pumps and UFH work well together
Oil / gas boilers work well with rads.

Both will work with either, though not to the same efficiencies

Edit: this is all stuff you should be sitting down and discussing with your architect.... Or if they are not confident to discuss these matters... With whom ever is carrying out the assessment.

Imo, your first port of call should be reducing the heat demand of the house in the first place, triple glazed, wall, floor and ceiling insulation, airtightness. If it means reducing the size of the house so you can build to a better spec, then I'd consider that tbh. No point having rooms you don't use while paying a fortune to heat them.

When you have your heat demand calculated, then look at the options you have to meet that, your BER assessor can help you there.

We are going for UFH upstairs and down, powered by an A2W pump. We know that system is only going to work well because of the level of insulation in the house, slab etc, it has all been designed around it....

Our architect made sure we hired an engineer to spec heating, heat recovery, window u value, insulation, PV requirement etc.
