How much will it cost to have cavity wall ties replaced?

Question

How much would it cost to have the front and back of a mid-size terrace house cavity wall ties replaced?

Also can cavity insulation be done at the same time and if so how much more will this add onto the cost?

Work is in Bristol - UK.

Thank you!

The ONLY way to arrive at the best answer for this question is to invite estimates/bids of local tradesmen/contractors.
