New build v extension/renovation regulations.

gooner99

I'm aware of the difference between new build and extension/renovation in terms of new build giving better opertunity for better building fabric and layout. But leaving that aside what are the differences between new build and an extension renovation in terms or regulations, contributions and other requirements.

I have on my list some difference in going for extension/renovation........

No development fees.

No ESB reconnection fees.

No requirement for new waste water treatment plant, assuming existing one is ok.

Lesser requirement for part L. No requirement for renewables. No requirement for BER.

No building control.

Heating system grants.

Insulation grants.

Vat reclaim for extension/renovation.

Any others?

No development fees. Wrong. Depending on the area, contributions on extensions are in place.

No ESB reconnection fees. True

No requirement for new waste water treatment plant, assuming existing one is ok. True ( assuming existing unit can take the increase)

Lesser requirement for part L. No requirement for renewables. No requirement for BER. True unless you are getting a grant. You then have to do a before and after BER.

No building control. Wrong

Heating system grants. True but again, BER required.

Insulation grants. True but again, BER required.

Vat reclaim for extension/renovation. True (once all registered for the HRI and tax compliant.

Thanks for the clarification. In relation to building control, is it to the same level or lesser?

Is the part L level much the same of are there less stringent requirements?

Any differences in other areas of the building regulations?

Anything else I'm missing?

Aside from what you've already mentioned, renovating may turn out to be more expensive if you have to undo and take apart work already done. It's harder to quantify the cost as there are more unforeseens.

Yeah I'm aware of that. I did mention leaving that aside in my earlier post.

If it's an extension under 40m² (regardless of whether it's the front, back etc) you could lodge a Short Form Commencement Notice (no documentation) on the BCMS which is less paperwork than a full BCMS Commencement Notice.

The essence of Part L for extensions is
- Limiting heat loss and where appropriate maximising heat gain.
- Controlling the output of space heating
- Limiting heat loss from pipes, ducts, vessels etc.
- Providing that all oil and gas fired burners have a minimum efficiency of 90%

There is no real requirement other than don't skimp on materials and construction method.

Thanks for the reply. Yeah would be paying attentions to the construction, insulation and airtightness improvements.
