INCA – Recognising Achievement
INCA Awards 2026 – Now Open
We’re delighted to announce that the 2026 INCA Awards will be hosted at the impressive Midland Hotel in the very heart of Manchester on Thursday 12th November – drinks reception starts at 18:45 and the event itself at 19:45.
Booking is now open and as usual we have three options – a premium table of 10, a standard table of 10 or individual tickets. Tickets are limited so early booking is recommended to avoid disappointment.
We will be judging against 10 project categories and entry is very simple – you will only need to decide if your project is residential or non-residential, and if it’s low, mid or high rise. We have also increased our non-project categories to include awards for training initiative and innovation.
