Party wall agreement in Portsmouth and across the South for building and adjoining owners

Established in 1996. Advice for both owners. Awards and schedules prepared.

Experience the difference

We understand the building work behind the notice

Party wall issues often sit alongside extensions, loft conversions, and structural alterations. Our engineering background helps us look at the practical implications, not just the wording on the page.

You get advice for either side

We can advise you whether you are planning the work or whether you are the neighbour affected by it. That gives you clear guidance based on your position in the process.

We keep the paperwork grounded and clear

We need to ensure that schedules and awards are accurate, as you may rely on them later. We prepare them carefully and explain what they mean in everyday language.

Clear guidance before work starts

Party wall matters can become complicated when construction affects a shared wall, boundary, or nearby structure. We provide guidance to both building owners and adjoining owners regarding the Party Wall Act 1996, helping you understand which sections apply before the work begins. This advice is especially important when planning an extension, loft conversion, or structural alteration, as it helps you avoid delays or disputes later on. 
 
Our practical building knowledge ensures that the paperwork is clear and expectations are realistic. Fast Calc Ltd supports property owners across Portsmouth and throughout the UK with straightforward advice that makes the next step easier to understand. When notices, schedules and awards need to be handled properly, we make sure you know where you stand from the outset and can provide residential structural engineering support where your project requires it.

"We use fastcalc regularly for works within the UK airports, they are always super efficient and helpful, we have never had anything other than a positive experience. After having other less favourable experiences with other structural engineers I wouldn't hesitate to recommend fast calc."

Support for notices, schedules and awards

Our role can change to suit the situation, because we can act as the agreed surveyor, the building owner's surveyor, or the adjoining owner's surveyor. We prepare schedules of condition to record the state of a property before work starts, which can be vital if damage is later alleged. We also produce party wall awards that set out how works should proceed and what protections are in place, alongside our short reports and condition surveys where a detailed record of a property's condition is required.
 
With experience dating back to 1996, we've seen how a well-prepared award can prevent small concerns from turning into expensive arguments. Fast Calc Ltd handles this work across Portsmouth and throughout the UK with a calm, methodical approach that keeps the process moving.
