Complete A-Z guide to surveying terminology, building defects, and RICS standards
A hazardous material used in UK buildings before 2000, particularly in properties built 1950-1985. Commonly found in ceiling tiles, insulation, floor tiles, and roof materials. Professional removal required. Costs: £1,500-£3,000+ for safe removal.
Associate membership of the Royal Institution of Chartered Surveyors. Entry-level RICS qualification indicating professional competency. Members working towards full MRICS status.
The most comprehensive RICS survey type (Level 3). Includes in-depth structural analysis, hidden area inspection, and detailed defect reporting. Cost: £630-£1,500+. Essential for pre-1850 properties, unusual construction, or poor condition homes.
Disagreement over property boundaries between neighbors. Surveyors can identify potential issues through land registry plans and physical inspection. Important for extensions and fence placement.
RICS Level 1 survey. Basic visual inspection using traffic light rating system (1-3). Suitable for new builds and conventional properties in good condition. Cost: £300-£900. Does NOT include valuation or hidden area inspection.
Water droplets forming on cold surfaces due to warm, moist air. Common in UK properties with poor ventilation. Can lead to mould growth and timber decay. Often visible on windows, walls, and in corners.
Process of measuring and tracking crack movement over time. Helps determine if cracks are active (structural concern) or historic (stable). Surveyors use tell-tales or electronic monitoring devices.
Most common UK property defect (affects 22% of homes). Three types: Rising damp (from ground), Penetrating damp (through walls/roof), Condensation (from moisture in air). Repair costs: £500-£8,000 depending on cause and severity.
Physical or chemical barrier preventing rising damp in walls. Typically located 150mm above ground level. Can fail in older properties or be bridged by raised ground levels or rendering.
Disrepair or damage requiring attention. In surveys, refers to elements in poor condition needing repair or replacement. Commercial property term for lease end repair obligations.
Legal right for someone to use part of your property (e.g., neighbor's access driveway, utility company cables). Surveyors identify potential easement issues affecting property use or value.
Document confirming electrical installation safety. Required for rental properties every 5 years. Homebuyers should request recent certificate or budget £200-£400 for inspection and £2,000-£5,000 for rewiring if needed.
Rating of property energy efficiency (A-G scale). Required for all UK property sales. Valid 10 years. Low ratings (E-G) may require improvements for mortgage approval and have higher running costs.

Traditional wall/ceiling construction using thin timber strips (laths) covered with plaster. Common in pre-1950s UK properties. Can deteriorate over time, causing cracks and sagging. Repair costs higher than modern plasterboard.
Property of special architectural or historic interest, protected by law. Grades I, II*, or II. Any alterations require Listed Building Consent. Survey essential to understand maintenance obligations and restrictions. Insurance costs 15-20% higher.
Structural wall supporting weight from above (floors, roof). Removal requires structural engineer approval and building control notification. Costs: £1,500-£3,000 for steel beam installation.

Basic property assessment for lenders (NOT a survey). Only confirms property worth exceeds loan amount. Does not identify defects or structural issues. Homebuyers should always commission separate survey.
Shared wall between properties (terraced, semi-detached). Party Wall Act 1996 governs work affecting shared structures. Notices required 2 months before works commence. Disputes resolved by party wall surveyors.
Water ingress through walls, roof, or windows. Often caused by defective pointing, render, roof tiles, or blocked gutters. Appears as damp patches worsening in wet weather. Repair costs: £500-£3,000 depending on cause.

Steel support beam for structural openings (removed walls, large windows). Building Regulations approval required. Installation costs: £1,200-£2,500 including structural engineer fees and building control.
Downward ground movement causing structural damage. Causes: clay soil shrinkage (drought), tree roots, mining, poor drainage. Signs: cracks >3mm, diagonal/stepped cracks, door/window sticking. Repair costs: £10,000-£50,000+. Affects insurance and resale.
Changes in building position/shape. Can be historic (settled, no concern) or ongoing (requires investigation). Surveyors assess crack patterns, widths, and locations to determine severity and cause.
Professional document detailing property condition, defects, and recommendations. Level 1: 8-15 pages, Level 2: 15-30 pages, Level 3: 30-60+ pages. Delivered 5-14 days post-inspection depending on survey type.
Wood deterioration from rot (wet or dry) or insect attack (woodworm, death watch beetle). Wet rot: common, localized. Dry rot: serious, spreads rapidly. Treatment costs: £1,500-£5,000+ depending on extent.
RICS rating scale for property condition: Condition 1 (Green) = No repair needed, Condition 2 (Amber) = Repairs/maintenance needed, Condition 3 (Red) = Serious defects/urgent repairs. Used in Level 1 and 2 surveys.
Professional estimate of property worth. Included in Level 2 surveys for mortgage and insurance purposes. Based on comparable sales, location, size, condition, and market factors. Valid 3-6 months.
Air circulation preventing condensation and damp. Modern building regulations require specific ventilation levels. Poor ventilation causes mould, condensation, and health issues. Solutions: extractor fans, airbricks, improved insulation.
