If 60 mm of Kingspan does the job then insulation regulations havent changed that much in the last three three years...??
from [broken link removed]
Only the last last three items in this list can meet the 0.27 W/mK requirement, athough 60mm of TW50 from Kingspan in a cavity will give 0.27 - see note below
Cabity Wall Insulation
100mm blown polystyrene, mineral wool, cellulose fibre
0.30
60mm extruded polystyrene insulation
0.40
35mm polyurethane foam board
0.39
35mm phenolic foam board
0.37
Timber frame 150 mm, mineral quilt
0.25
Timber frame 140mm, cellulose fibre
0.19
Safewarm home construction
0.31
Note the above take no account of building volume, area of heat loss elements or air tightness as described by sydthebeat.

taydo....
show him this:
[broken link removed]
point him towards paragraph 7 (1)..... which states
7. (1) A person who commissions the construction of a building of a class referred to in subparagraph (a) or (b) of paragraph (4) construction of which commences on or after such date specified for that class in the said subparagraphs shall, before such building is occupied for the first time, secure a BER certificate (in the form prescribed by the First Schedule or Second Schedule to these Regulations, as appropriate) and advisory report in relation to the building and shall produce a printed copy of such BER certificate and advisory report to the building control authority in whose functional area the building is situated, on demand being made by that authority for its production.
(5) The provisions of subparagraphs (a) and (b) of paragraph (4) shall not apply to the following buildings – (a) a new dwelling for which planning permission was applied for or a planning notice was published on or before 31 December 2006 , and where substantial work is completed by 30 June 2008;
[FONT=Arial,Arial][FONT=Arial,Arial]I have bolded up the relevant wording.[/FONT][/FONT]
[FONT=Arial,Arial][FONT=Arial,Arial]To be honest, it doesnt fill me with much confidence that your 'engineer' isnt up to speed with a law thats in place now nearly 2 years!![/FONT][/FONT]
[FONT=Arial,Arial][FONT=Arial,Arial]Edit: corrected operative dates[/FONT][/FONT]
I'd say the engineer is right - speaking realistically.
I built three years ago. No one from officialdom ever came and inspected the insulation, the wiring done, or indeed anything to do with the building quality. I suspect that will not change so in effect the 1st inspection for compliance with new insulation standards will come when the house is going to be sold.
Taydo,
The ref that sydthebeat posted regarding "the building being substantially complete by 30th June 2008" is for planning that was applied for planning before 1st January 2007.
Any house that applied for planning after 1st January 2007 requires a BER cert and had to comply with TGD 2005.
If the property is not substantially completed by 30th June 2008, the TGD 2007 will apply.
So you will have to check when planning was applied for to see what level of compliance you need.
Didn't apply for it before 1 jan 2007.
Should this not be:we have to keep BER and TGD L separate for clarity:
Part L
2007 applies if the dwelling was applied for permission after 1st July 2008
and if not substantially complete by 1st July 2009
2005 applies otherwise
Should this not be:
2007 applies if the dwelling was applied for permission after 1st July 2008
OR
if permission was applied for before the 1st of July 2008 AND the dwelling is NOT substantially complete by 1st July 2009
2005 applies otherwise
did you not have to get your build certified?
Yes. But its 6 quick onsite chats with people that I appoint and pay. No measuring tapes were produced. Its almost self certification. Hardly strigent ?
You need someone from officialdom doing it as they do in the North.
These transitional arrangements can be confusing. Iam trying to these these clear in my own head, as well.
The OP said that planning was applied for after 1st January 2007. So a BER cert is required. If we know that the building was substantially complete by 30th of June 2008, then the 2005 Regs apply.
Is my summary right?
sydthebeat,
I know you post regularly in regard to Ber !
Was the 30th June 2008 deadline extended for a year until 2009, before 2007 Regs kick in.
I am assessing a number of 07/early 08 planning applications. These have until June 09 before 2007 Regs kick in ?
Thanks sydthebeat for the clarification. I did not know the different dates between Part L and BER.
Could I ask you about the glut of unsold new houses across the country. While many of them are fully completed, will they require a BER when they are sold next year. Some houses in my estate were built under a 2003 permission. What will they be assesed under next January. New build or existing ?
