Chancellor Rachel Reeves announced on Wednesday that proposals for a controversial third runway can once again be explored.
Expanding the airport would be the largest privately funded transport infrastructure project in Europe.
Spelthorne Borough Council says it recognises the potential economic benefits and opportunities it is likely to bring to the area.
However, it says support is dependent on making sure that any scheme comprehensively mitigates against a number of impacts.
These are noise, traffic, air quality, the wider environment, infrastructure and road networks.
