That is good. We achieved 4.1 for a detached traditionally built large chalet bungalow yesterday.

 

Edit: Although 3,500sq.ft is quite large for a chalet bungalow hence the ‘large’ comment.

Our bungalow is only 765sq.ft

nerve wracking waiting for the test results isn't it! With ours I 'needed' a result between 3 and 5 m3/h.m2 @50Pa so 3.7 was ideal (For the SAP design calcs I'd committed to a value of less than 5 but also needed a value greater than 3 as the building is naturally ventilated.

It's a holiday home that only gets used at weekends and, unlike most new-builds on this forum, it is built to minimum building regs requirements however total heating, hot water and cooking costs for the last 2 years averaged just £140/year using bulk LPG + standing charge.
