Assuming that Harold later agrees to pay the original price of £700, did he accept Wesley's offer?

In contract law, acceptance must be clear and unequivocal, and it must correspond to the terms of the offer made. In this case, if Wesley made an offer to Harold with specific terms, which presumably included a price different from £700, Harold's agreement to pay the original price indicates that he did not accept the specific terms of Wesley's offer as they were presented.

Harold's action of agreeing to pay £700 does not constitute acceptance of Wesley's offer unless that price was what was originally offered. If the offer included different terms or conditions, simply agreeing to a different price implies a counter-offer rather than acceptance. For acceptance to be valid, it must align perfectly with the offer without introducing new conditions or changing the terms. Since Harold did not align with the original offer's price or terms, he did not accept Wesley's offer.
