Hi to all
Having new heating and hot water gas boiler installed, can anyone advise me as to what paperwork i should be presented with after installation.
Warranty
Gas cert
etc etc

Many thanks

I had to get a certificate of first installation, as the original installer did not supply one and I failed to keep his contact details. I found out on the regular 5 year inspection.

The company/guy you choose should be on the authorised list here, then there shouldn't be any problem with certificates afterwards. They should also carry an installer's licence (carnet de instalador de gas).
