CWI guarantee CIGA

Is this the normal reply from ciga:

However, CIGA is unable to guarantee the performance of the product once installed, and this is totally reliant on several other factors to include water vapour extraction, regular ventilation and adequate heating control. So therefore we will come out & do an inspection.

that this property shouldn't have had CWI installed due to it's location(West coast of Cumbria).

We believe the CWI is not working/failed & are waiting for an inspection to be done.

Is it worth pursuing them & if so, best way. Many thanks

Strictly it's a warranty not a guarantee, so there are legal differences, and you should regard it as being defect based, not outcome based.

So the warranty covers issues related to the installation [operation] and not the suitably or performance of the product.

Cheers Woody for the reply. I must admit i was hoping as it shouldn't have been installed in the first place due to the house unsuitability, that i might have some redress that way.

Yes, there is clear guidance on the pre-installation inspection and checks under the BBA or similar approval certification (required under Building Regulations), together with the manufacturer's own requirements for installation.

Things like location, exposure, narrow cavity, clear cavity, condition of pointing.

I suspect that you would need to bring a claim of negligence against the installer. You may also have a claim against any grant funding provider and also any finance provider if you used that.

If you have legal cover on your home insurance, ask them for advice.

The standard recommendation for significant home works, is to always pay at least £100.01 on finance (eg a deposit) to get protection under consumer legislation.

Unfortunately it was already installed when we bought the property so i don't know who installed it either. I would imagine the original installer is no longer in business now too.
