If you have read a Party Wall Award before, you may have seen conditions about percussive tools—for example, restrictions on heavy breakers, impact drills, or demolition hammers, and a requirement to use hand tools in certain locations. Some building owners see these clauses as inconvenient. Many adjoining owners see them as reassuring.
At Simple Survey, we include sensible tool-control clauses in our Awards because the principle is straightforward: reduced impact means reduced vibration, and reduced vibration means the risk of damage to the party wall and neighbouring property is as low as reasonably practicable.
This article explains, in plain terms, why percussive tool controls appear in Awards, how they link to the Party Wall etc. Act 1996, what they mean for both owners, and what to do if vibration becomes a concern.
1) The Party Wall etc. Act 1996 in plain terms
The Party Wall etc. Act 1996 applies in England and Wales. It provides a legal framework for certain works that may affect:
- a party wall (shared wall between neighbouring properties),
- a party structure (for example, shared walls or floors between flats),
- certain boundary wall situations, and
- certain excavations near neighbouring buildings where foundations could be affected.
The Act is intended to facilitate works by providing a clear process: notice, neighbour response, and—where written consent is not provided—a structured surveyor route and formal Award to conclude matters properly.
2) Where tool restrictions sit within the Act
Percussive tool controls do not appear because the Act lists specific tools. They appear because the Act provides a framework for controlling how notifiable works are carried out when they affect shared structures or neighbouring property.
Tool-related controls are most commonly relevant where the works fall into:
- Section 2 works (works to an existing party wall or party structure), with notice served under Section 3; and/or
- Section 6 works (adjacent excavation) where vibration and ground disturbance can matter; and/or
- projects with boundary elements under Section 1 where work is very close to the dividing line.
When an Award is required (typically through the dispute procedure associated with Section 10), surveyors commonly include conditions that reduce risk. Tool-control clauses are one of the most practical and widely understood forms of risk reduction.
3) The Party Wall process: Notice → Response → (if needed) Award
It is helpful to place this into the normal sequence:
Stage 1: Notice
The building owner serves the relevant notice(s) depending on the works:
- Section 3 notice for Section 2 works (often 2 months’ lead time),
- Section 6 notice for excavation (often 1 month’s lead time), and/or
- Section 1 notice for certain boundary works (often 1 month’s lead time).
Stage 2: Response (14 days)
The adjoining owner may consent, dissent, or not respond. Where there is no written consent, the matter proceeds through the statutory dispute route.
Stage 3: Award (commonly Section 10)
Where required, surveyors set out a formal Award. This is where method conditions are commonly written down—such as restrictions on percussive tools near the party wall or near sensitive areas—so that the works proceed in a controlled and proportionate way.
4) What “percussive tools” means in practice
“Percussive tools” is a broad phrase, but in simple terms it refers to tools that operate by repeated impact or hammering action. These tools can generate vibration through masonry and structure.
Vibration can travel:
- through the party wall,
- through floors and connected structures (especially in flats),
- and, in some circumstances, into neighbouring elements.
This does not mean percussive tools are always unsafe. It means they must be used selectively and proportionately. A well-managed Award condition will typically focus on the areas where vibration risk is most relevant: close to the party wall, close to shared structures, and close to parts of the neighbour’s building that could be affected by vibration transmission.
5) Why hand tools are often required (and why we include them)
At Simple Survey, we often specify the use of hand tools in sensitive areas because:
- hand tools generally produce less vibration than heavy percussive demolition,
- they reduce the risk of shock loading the party wall,
- they reduce the likelihood of cracking and disturbance in shared masonry,
- they allow more controlled removal and adjustment, which is usually tidier work.
In plain terms: hand tools reduce impact, and reduced impact reduces risk.
This is why hand tool clauses appear so frequently in Awards. They are one of the simplest ways to demonstrate that the works are being carried out with care for the shared structure.
6) “This applies to all works under the Act”: what that means in reality
Tool controls are most directly relevant where the works:
- are to the party wall itself (Section 2 works),
- affect party structures between flats (also within Section 2 scope), or
- could transmit vibration into adjoining structures during adjacent excavation or close structural alterations.
So while the Act covers different categories of work, the practical principle is consistent: if the works could reasonably transmit vibration into shared fabric or the neighbour’s structure, it is sensible to control methods in a way that reduces risk.
This is not about punishing building owners. It is about avoiding foreseeable damage and foreseeable disputes.
7) Guidance for building owners: ignore tool restrictions and expect consequences
A professional point needs stating plainly. If an Award requires controlled methods—such as limiting heavy percussive tools near a party wall—and the contractor ignores it, you should expect two likely outcomes:
- Increased risk of damage
Vibration is one of the most common triggers for cracking and disturbance complaints. - Increased risk of dispute and claims
If an adjoining owner experiences significant vibration, they will often assume (reasonably) that the work is being carried out aggressively. That shifts the relationship from cooperative to suspicious. Suspicion leads to claims, extended correspondence, and escalating costs.
In short: ignoring the Award’s method requirements is not “faster”; it is usually more expensive in the end.
The cost-saving mindset is to comply with sensible method conditions because they reduce risk and reduce neighbour friction.
8) Guidance for adjoining owners: if you feel vibration, act promptly and properly
Adjoining owners are not expected to tolerate significant vibration without query. If you are experiencing vibration on the party wall or within your property during notifiable works:
- do not confront contractors aggressively on site,
- do not let frustration build for weeks,
- and do not rely on informal messages alone.
The correct practical step is:
- contact your surveyor promptly (where surveyors are appointed),
- describe what you are experiencing (time, duration, general location), and
- request that the method is checked against the Award requirements.
Early action helps because if method changes are needed, it is far easier to adjust early than after weeks of concern.
A key point: feeling vibration does not automatically mean damage has occurred. But it is a reasonable sign to ask whether methods are being controlled properly.
9) The Simple Survey approach: clear, proportionate, workable conditions
We include hand-tool and percussive-tool controls in our Awards because they are:
- easy for homeowners to understand,
- straightforward for competent contractors to follow,
- effective as risk reduction, and
- helpful in keeping neighbour relations calmer by demonstrating professional restraint.
We do not believe in theatrical conditions. We believe in practical ones: clear wording, realistic requirements, and a focus on reducing foreseeable risk.
