Party Wall Survey Services in London
Navigating the complexities of shared boundaries can feel like walking through a legal minefield, but conducting a Party Wall Survey doesn’t have to be stressful. Whether you are planning a loft conversion, a rear extension, or need to regularise existing works, our professional architectural and surveying services provide you with the legal certainty you need. A Party Wall Survey acts as your shield against future legal disputes and planning enforcement action. Think of it as an insurance policy for your property development—once obtained, it provides formal confirmation from a qualified professional that your works are being carried out safely and lawfully. This isn’t just paperwork; it’s your guarantee that solicitors, mortgage lenders, and future buyers will have complete confidence in your property.
What is Party Wall Survey ?
A Party Wall Survey is a technical assessment and formal record issued to confirm that proposed or existing works comply with the Party Wall etc. Act 1996.
- Technical Expertise: It combines deep technical knowledge with an expert assessment of your rights and obligations.
- Condition Record: The process includes a “Schedule of Condition,” which serves as your guarantee of the property’s state before work begins.
- Dispute Resolution: If neighbours dissent to a notice, the survey process ensures the decision is based on technical facts and evidence, not planning judgement.
- Legal Shield: It protects you from expensive surprises and baseless claims from planning enforcement officers or neighbors
Types Of Party Wall Survey
Certificate of Lawfulness – Proposed Development
(CLOPUD)
Get legal peace of mind before you build. This certificate confirms that your planned extension, loft conversion, or outbuilding falls under “permitted development.” It’s a vital step for ensuring your investment is legally protected before work begins.
Certificate of Lawfulness: Existing Development
(CLEUD)
Formalize what’s already there. A CLEUD confirms that an existing structure or use of land is lawful. This is essential for works completed without prior planning permission that have been in place for more than four years (or ten years for changes of use).
