Extension and Renovation

FixdePitchmark

Guys purchased a house and have got planning for dormer conversion side and rear extension

Just to be clear - do you need to comply with Part L of building regs ?

I'm obviosuly doing everything to as high a standard within budget.

Was planing under floor heating
Gas Combi Boiler

Tripple glaze
Full reinulated

But not sure that would comply ?

For example - no renable source ?


Thanks again
BER Cert on purchasing was F - we hope to get to A2.

Yes you need to comply with part L, insulation, and air-tightness and glazing ratio calculation

Not necessarily the renewable requirements that apply to new builds
