Which loft works can trigger a notice?
The government's explanatory booklet specifically includes cutting into a party wall to support a beam for a loft conversion. Raising the wall is another example. The question is what happens to the shared structure, not whether the new room itself stays on your side of the property. [1]
The Act also covers certain party structures, which can include floors or partitions separating flats. Conversely, minor activities such as ordinary fixing holes or replastering may be too minor to require notice. Have the proposed structural details checked rather than using a general statement that all lofts are covered or all internal work is exempt. [1]
Identify the owners and describe the work
There can be more than one adjoining owner for a property, including freehold and qualifying leasehold owners. Telling the person living next door is not necessarily the same as serving everyone who must receive notice. [1]
The notice needs the relevant owners' details, the property address, a full description of the proposed work and the intended start date. Plans can help explain beam positions and alterations, but they do not remove the need to describe the work. You can serve notice yourself; professional help may be useful where the ownership or structural scope is complicated. [1]
Allow the correct time
For work to an existing party wall or party structure, notice must be served at least two months before the planned start. The adjoining owner can agree to an earlier start but is not obliged to do so. The notice is valid for one year. [1]
After service, the adjoining owner may consent in writing or dissent. If there is no response within 14 days to this type of notice, a dispute is deemed to have arisen. Silence is not permission to begin the notifiable work. [1]
Consent and an award are different routes
Where there is consent, a dispute-resolution award is not automatically needed at that point. Consent does not remove the building owner's continuing duties, including avoiding unnecessary inconvenience and dealing with damage caused by the works. [1]
Where a dispute arises, the owners can appoint one agreed surveyor or each appoint a surveyor under the Act's procedure. The surveyor or surveyors resolve the disputed matters through an award. They must act impartially rather than simply pursue the wishes of the person who appointed them. [1]
An award can set out the work, its timing and protective measures, and often includes a record of the neighbour's property's condition. Keep the notices, responses and any award with the project documents. [1]
Budget and coordinate before site work
Where the work is solely for the building owner's benefit, that owner usually pays the reasonable costs associated with the award, including the adjoining owner's surveyor. Fees are not fixed nationally, and different cost-sharing situations can arise for repairs or defects. [1]
Settle the beam and wall proposals early enough to use the correct process. Starting without proper notice can expose the project to an injunction or other legal action. Obtain project-specific professional or legal advice where the Act's application or the parties' rights are disputed. [1]
