A

Asbestos

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.

AssocRICS

Associate membership of the Royal Institution of Chartered Surveyors. Entry-level RICS qualification indicating professional competency. Members working towards full MRICS status.

B

Building Survey

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.

Boundary Dispute

Disagreement over property boundaries between neighbors. Surveyors can identify potential issues through land registry plans and physical inspection. Important for extensions and fence placement.

C

Condition Report

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.

Condensation

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.

Crack Monitoring

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.

D

Damp

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.

Damp Proof Course (DPC)

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.

Dilapidations

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.

E

Easement

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.

Electrical Safety Certificate

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.

Energy Performance Certificate (EPC)

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.

F

FRICS

Fellow of the Royal Institution of Chartered Surveyors. Highest RICS membership level, recognizing extensive experience and senior professional standing. Minimum 5 years post-MRICS qualification.

Flat Roof

Roof with minimal slope (typically 1-10 degrees). Common in UK extensions and modern buildings. Lifespan: 10-20 years depending on material. High maintenance; replacement costs: £40-£80 per m².

L

Lath and Plaster

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.

Listed Building

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.

Load-Bearing Wall

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.

M

MRICS

Member of the Royal Institution of Chartered Surveyors. Full professional qualification requiring university degree, structured training (APC), and professional competency assessment. The gold standard for UK surveyors.

Market Valuation

Professional assessment of property's market value. Included in RICS Level 2 surveys. Separate service costs £200-£300. Based on comparable sales, location, condition, and market trends.

Mortgage Valuation

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.

P

Party Wall

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.

Penetrating Damp

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.

Pointing

Mortar between bricks or stone. Deteriorates over time, allowing water penetration. Re-pointing costs: £40-£60 per m². Essential maintenance for older properties.

R

RICS

Royal Institution of Chartered Surveyors. Professional body regulating surveyors in UK and globally. Sets standards for surveys, valuations, and professional conduct. Always choose RICS-certified surveyors for consumer protection.

Rising Damp

Groundwater rising through walls via capillary action. Limited to ~1 meter height. Signs: tide marks, salt deposits, peeling wallpaper/paint. Treatment: install/repair DPC, improve ventilation. Costs: £1,500-£3,000 for typical terraced house.

RSJ (Rolled Steel Joist)

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.

S

Subsidence

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.

Structural Movement

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.

Survey Report

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.

T

Timber Decay

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.

Traffic Light System

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.

V

Valuation

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.

Ventilation

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.
