Should you wish to respond to the BCE, they are very clear about how they would like to see responses presented and their guidance states:

“Those who respond to the consultation are requested to say whether they approve of, or object to, the BCE’s proposals. In particular, objectors are advised to say what they propose in place of the BCE’s proposals. An objection accompanied by a viable counterproposal is likely to carry more weight than a simple statement of objection. In this respect – and particularly in light of the importance of Rule 2 (statutory electorate range) – a counterproposal setting out the composition of each constituency in an area will generally be viewed as more persuasive than a proposal for the composition of only one constituency which does not address any knock-on effects on the electorate figures of neighbouring constituencies.”

Please bear this in mind if you make a response.   Essentially – there needs to be a rationale for your views which takes into account the impact on neighbouring constituencies as the key parameter is the number of electors in each constituency.     The BCE is keen to gather all views at this stage, supportive and otherwise, so not just objections.
