Retrospective Party Wall Agreement

This is a party wall Award that is put in place once party wall works are partially or have been fully completed.

They are sometimes agreed in order to deal with allegations of damage, or claims made. They may also be put in place to provide clarity on the scope of works carried out, and include ‘as – built’ drawings, or similar.

In order to draw up a retrospective party wall agreement, an Agreed Surveyor, or two party wall Surveyors need to be appointed under Section 10 of the Act, with the knowledge of both Owners concerned.

At Harding Chartered Surveyors, we’re a team of independent and impartial RICS surveyors that can carry out party wall matters. If you have any questions or need advice don’t hesitate to call us on 020 3598 6730.

Retrospective Party Wall Agreement, Harding Chartered Surveyors
  • If you are selling your property, you should seek advice from a conveyancer or solicitor about whether you can get some form of indemnity insurance in the event of any claims being made later (once the conveyance has taken place). 
  • Otherwise, you would need your neighbour(s) to 'buy in' to the principle of a retrospective Award being put in place - the Surveyors (and it can end up being two separate surveyors) costs of doing so can often exceed any reported claims of damage. If you do not get on with your neighbour(s), then this is the kind of thing that may need to be declared as a 'dispute' with your next door neighbour, on conveyancing questionnaires.
  • Surveyors can't give a timescale or a fixed cost of taking on such instructions, as it is all based on a supposition, and the information that they would usually have may not be available.
  • The timescale of putting a Retrospective Award in place may not accord with the vendor's, or buyer's intended programme.
  • If you are a buyer, you will need to make your own enquiries to satisfy yourself before a conveyance takes place; and again, getting indemnities in place if you are advised to do so.

We used Hardings to compile an independent expert witness report for some poor workmanship we had completed at our home. Their report helped us win our case and reclaim our costs.The report was concise, succinct and detailed - providing everything we needed to win our claim.
I have used Harding Chartered Surveyors service for a new build snagging survey. The report was thorough and detailed beyond expectations. The communication with the surveyor was excellent and the end-to-end process was very easy and efficient. I would definitely use them again and recommend to a friend.
The team at Harding Chartered Surveyors were fantastic to work with. Kate helped us identify the work we needed and arranged a surveyor to visit our property. Throughout, she was clear about timescales, costs, and next steps. Our surveyor, Scott Ingham, was thorough and helpful, speaking with us by phone immediately following the survey about the largest areas of concern (which, thankfully, were not major!). The report that was produced was easy to read and helped us understand what areas of the property might need work with approximate timelines and costs. All of the work happened on time, and there were no surprises in the process. Everyone was friendly, professional, and helpful. I highly recommend!!
I highly recommend Hardings. All communication and interactions with them was high professional. Alaa dealt with my survey. He approached it with a high level and depth of knowledge, he was honest and considerate giving balanced advice. Throughout he was a pleasure to deal with.I also dealt with Kate making the arrangements. She was also prompt, professional and polite . Harding’s came highly recommended to me. My experience would endorse that they are a family run business with integrity and professionalism at their core.

We are very pleased with the service you have provided and would certainly recommend you in future .
Very positive experience. We hired Harding Surveyors to carry out a building survey on a commercial property to be leased from the council. They did a great job and we went back to them again to carry out a schedule of condition report, prior to us moving in. Very helpful, friendly, good communication, and reasonable price. Would recommend.
