Meeting Centre of Gravity for UK Postcodes

Use this tool to find the best place to hold a meeting for its attendees by inputting their UK postcodes. The COG tool will then work out the centre of gravity for the meeting. This will be represented by a marker on the map.

Meeting COG Map


Input Data

Input a list of UK postcodes. For example M60 7RA or EC3N 4DR

Postcodes must be in uppercase. Each postcode consists of two parts. The first part (outward postcode, or outcode) is separated by a single space from the second part (the inward postcode, or in-code).

  Postcode (min=2,max=10)
Postcode 1
Postcode 2
Postcode 3
Postcode 4
Postcode 5
Postcode 6
Postcode 7
Postcode 8
Postcode 9
Postcode 10

 Find COG 


Further Information

Once you input the postcodes, this tool will work out where the best place is to hold the meeting. This will be a point on the map where, if all attendees could travel in a straight line to get to, would give the least combined travel time for them to meet up. You can enter full UK postcodes (incode & outcode) for more accuracy.

Yes, of course people cant travel in straight lines and they cant hold the meeting in a field, in the sea or in some strangers house if that is what the tools tells you. You are then expected to use that as a base from which to find a meeting venue close by, be it a pub, park or hotel etc..

Let us know if this tool comes in useful to you by posting a comment below. It will be interesting to find out how it is used.

hello, I have put in three postcodes and none of them could be found. They are RG20 5PD, BA12 8AB and GU30 7la. I have tried them with a without a gap and in upper and lower case but all are rejected

Hi Sue, could you provide some or all the 3 postcodes you input?
By Free Map Tools on 29th November 2020

Really wanted this to work but hasn't recognised any of my 3 postcodes
By Sue Wright on 29th November 2020

Great idea, but does not work. Didn%u2019t recognise all 3 postcodes I entered from different areas of the country.
By Matilda on 13th November 2020

Both YO25 9TG and PL19 9AN work fine when tested :
By Free Map Tools on 2nd October 2020

Simply doesn't work-as with all the other .com tools I've looked at -will not recognise YO25 9TG OR PL19 9AN

Hi tried it again and hey presto it worked so it does work. Triangulated it by hand and the app was almost spot on. Well done but the result should be super quick or you will move on. Thanks anyway.
By Paul on 10th September 2020

Hi Paul, can you give examples of the postcodes you entered please?
By Free Map Tools on 9th September 2020

Great idea but your app doesn%u2019t work. Entered postcodes, press COG, then nothing. Rubbish app
By Paul on 9th September 2020

Thanks Michael

The first sentence on this page says, "Use this tool to find the best place to hold a meeting for it's attendees by inputting their UK postcodes." No apostrophe is needed in the word 'its' in that sentence.
By Michael on 29th August 2020

Graham, we believe this would work.

If you need to find cog of (say) 50 postcodes can you find the post codes of 5 groups of 10 using the system, and then put these 5 into the system to produce an overall for the 50? Would this work?
By Graham Alan Slater on 26th July 2020

Hi Greg, it expects full postcodes (e.g. M26 4LW) not just the postcode sector.

Weird just tried click find COG again and looks to have changed and now correct!
