Services
RICS Homebuyer Survey
Our RICS Homebuyer Surveys provide comprehensive property condition assessments for residential purchases. The survey identifies structural issues, maintenance requirements, and potential repair costs. Our chartered surveyors deliver clear, actionable reports to support informed property decisions.
Building Survey
Detailed building surveys examine all visible and accessible elements of commercial and residential properties. We assess structural integrity, material condition, and compliance with building regulations. Reports include prioritised repair recommendations and cost estimates.
Commercial Valuation
RICS-compliant commercial valuations consider property condition, location, and market trends. We provide accurate assessments for business transactions, tax purposes, or lease negotiations. Reports include supporting market evidence and legal compliance checks.
Lease Extension Valuation
Specialist lease extension valuations under the 1993 and 1967 Acts determine fair premiums. We consider property value, remaining lease term, and ground rent. Our reports support statutory lease extension processes.
Expert Witness Services
Our chartered surveyors provide expert property testimony for legal disputes. Services include defect analysis, valuation disputes, and boundary assessments. We prepare court-compliant reports and provide courtroom testimony when required.

Good price, talked to around ten agents and Aston James turned the valuation extremely quickly. They visited the property on the day I phoned, got the valuation in time for the board meeting and the charity I work for were able to contract to buy the house. Thanks to Mischa for sorting it all out and understanding the urgency.

Patrick at Aston James Associates carried out a buildings survey for us. He provided a clear and detailed report which was easy to understand. It was much better than a report we commissioned on a different property last year. The only reason I have given 4 stars rather than 5 is because we had to wait longer than expected for the report.
