This is obviously the easiest route. If you wanted to save monies you could hold the reception at your home and prepare the food yourself. Although this can be quite a fair amount of work at an emotional time and may not be suitable for most.
Some church halls do not charge a great amount for a few hour’s hire, so again you could try your local church and enquire how much the cost would be. You can of course also look in local directories, and the internet for function rooms, hall hire, church halls to hire, which are near to you. However… this can be quite a time-consuming process unless you are fortunate and find somewhere suitable early on when looking. You would still of course have to supply the food and drinks, which again may not be suitable for most.
Another reception venue which is generally easier to arrange could be a local public house. I have been to two funerals where they held a reception in a section of the local public house near to the Crematorium. The families told me that they did not want the reception to be a dreary affair in a hall. In both cases, the pub supplied the food and the guests bought their drinks so that there was no financial pressure on the families to cover the drinks bill. I must admit that as a guest, both these receptions were the brightest ones I have attended. The costs are often lower, compared to hiring halls and catering firms.
