The Real Truth About Party Wall Insurance

Are you considering a large scale home renovation? The Party Wall Act protects you and your neighbours during home renovations, and failure to follow the correct procedures could land you with a hefty bill. As anyone who is considering an extension or renovation project will have realised, neighbours have a very important role to play in many aspects of the planning process. It is crucial that you keep them informed at every stage of the project development. Not only will they experience some of the pain from the early mornings, loud drilling, constant dust and lack of parking, your work could affect their property. It is also a point of law that you must give them plenty of notice before starting work on the project. Legally, this notification must be given to the neighbours at least two months before notifiable work will begin, and at least one month before any excavation works start. It should be stated that ‘notifiable work’ is defined as either building work which will affect a Party Wall or boundary line, or excavations within three or six metres of the neighbouring property (depending on the depth of hole/foundation). This notifiable work will mostly include extensions, basement and loft conversions but also any works that may include structural changes to a party wall.

A Party Wall notice must be served to all owners of all neighbouring properties which may be affected by the works; including both freeholders and leaseholders. Once this act has been agreed and signed, you can take up to a year to start work. Although, if your plans change, however slightly, you should submit a revised drawing to your neighbours, but not a new notice. As long as you are keeping them informed and up to date, you are operating within the terms of the agreement.

There is ‘realistic potential’ for damage when undertaking Party Wall works, according to The Royal Institution of Chartered Surveyors. Therefore, it’s not surprising to hear that failure to comply with the act could result in your neighbour taking you to court and getting an injunction to prevent the continuation of your project – all at your expense.

The Party Wall process

Once you have served notice, your neighbours, known as “the adjoining owners”, have a maximum of fourteen days to respond to your notice. Then, once they have agreed in writing, work can start -immediately if you wish. However, if they fail to reply or disagree then the matter goes into dispute, which can become rather expensive and time consuming.

Next you should give your neighbours at least 10 days to decide whether a surveyor can act on behalf of both of you, or if they wish to hire their own. The surveyor involved should draw up the Party Wall award (this lays out the rules which the builders involved must adhere to), as well as surveying all affected properties before and after the work has been carried out to check that no damaged as occurred which you need to repair. It isn’t necessary to use the same surveyor, however, it can save you a large sum of money, be extremely convenient in terms of communication and coordination. This person is known as the ‘agreed surveyor’. This is one of the main reasons why you should discuss your project with your neighbours before serving the Party Wall notice and ask for their feelings on the matter.

Here is an example timeline to put the Party Wall agreement into perspective:

  • Day one: You must serve the Party Wall notice to all neighbours (anyone with an interest of more than one year) citing the relevant sections , stating the project, purpose, when work will start etc.
  • Day fifteen: The neighbours you have served the Party Wall notice to must have agreed in writing to your notice. If they disagree, then you should send them another letter stating they must appoint a Party Wall surveyor within the next ten days, or you will appoint one on their behalf.
  • Day twenty-six: At this point, your neighbour should have decided whether they wish to appoint their own surveyor, and if they haven’t, then you can on their behalf. However, it must not be the same surveyor that you are using. Although the fees are likely to be the same regardless of how may surveyors you use, it is important to keep the lines of communication open between all, for the continuity and success of the project.
  • Day twenty-seven: From this day onwards, you must give all responsibility to your appointed surveyor(s), who will assess the condition of your neighbour’s property so it can be checked later after the work has been completed. If you haven’t heard back from your neighbours by then, and if your surveyor deems it necessary, they are able to trespass on your neighbour’s property in order to carry out the Party Wall assessment.
  • Day one, plus two months: Work can officially begin if the Party Wall agreement has been agreed by all surveyors and parties involved.
