Do you mind me asking how much they charged (per sqm?)

Here's an excerpt from the email that came with a quote I received in August 2025, if that's any help:

 

"Pleased to provide a quotation for the airtightness works in your project - to view in full, please click the Quotation link above. For the supply and installation of the AeroBarrier system in your 190m2 project in [my postcode], your installation would be £2,538.40 (ex VAT but zero rated on new builds). This price is inclusive of travel, labour and materials and we do not charge a premium or any added fees for you end airtightness target (even to high performance levels)."

Good riddance. He was a cock.

Half a cubic metre per hour per square metre of exposed area is considered quite good.

Has anyone managed that without filling the house up with glue?

Seem to remember that someone got a 0.23 m³.h^-1.m^-2.

Start and end, not measured in ACH, but once we get volumes the conversion can be made.

From 3.9 to .5 and you think that needs improvement?  I think i must have missed something on mine to end up at 1.4. Which i thought was reasonable actually.  The lads from AB  did say the windows and door sealing was very good. Wonder where i was still losing air from.

No, not really, .5 is more than good enough for me, originally I said 1.5 and I'd be very happy, just a bit pee'd off at the windows because it's so obvious.  My fault for being soft as shite and not inspecting 100%.

I guess you didn't tape the windows & doors yourself then.

 

The only place i can think of that might have let down my score was the fact that the floor screed did not flow as hard to the edges as i imagined it would and the sole plate being a little suspect. I can imagine that once pressurised, air was getting down past the edges of the screed and out through the sole plate gaps.

Either way its costing me no more to heat than i was paying for my old 3 bed semi at less that half the size.
