Property survey guide

Buying a property in London is one of the biggest financial decisions you'll make. A professional property survey by RICS chartered surveyors protects your investment by identifying issues before you commit. This complete guide explains everything home buyers need to know about surveys.

What is a Property Survey?

A property survey is a detailed inspection of a building's condition carried out by a qualified chartered surveyor. Unlike a mortgage valuation (which only confirms the property is worth the loan amount), a full survey assesses the condition of the property and identifies defects, repairs needed, and potential problems.

Our building surveyors examine everything from the roof and structure to damp issues and electrical concerns. The detailed report helps you make an informed decision about whether to proceed with the purchase, renegotiate the price, or request repairs before completion.

Types of Property Surveys

RICS Level 2 Home Survey (Homebuyer Report)

The RICS Level 2 survey is the most popular choice for home buyers purchasing standard properties built within the last 150 years that are in reasonable condition. This homebuyer report provides:

  • Assessment of the property's condition using a traffic light rating system (1-3)
  • Identification of urgent defects and issues requiring immediate attention
  • Advice on repairs and ongoing maintenance
  • Optional market valuation and insurance rebuild costs

This survey type strikes the perfect balance between cost and comprehensiveness. It's ideal for conventional residential property in East London, West London, South East London and across the capital.

RICS Level 3 Building Survey

The RICS Level 3 building survey is the most detailed and comprehensive survey available. Our chartered building surveyors recommend this for:

  • Properties built before 1900 (Victorian, Georgian, Edwardian homes)
  • Buildings in poor condition or requiring renovation
  • Properties with unusual construction or significant alterations
  • Homes you plan to renovate or extend

This survey includes extensive investigation of the building's construction, detailed analysis of defects, expert advice on repairs with cost estimates, and recommendations for specialist investigations if needed.

Why You Need a Property Survey

Peace of Mind

A professional survey gives you confidence in your purchase decision. You'll know exactly what condition the property is in and what issues might arise in the future. This peace of mind is invaluable when making such a significant investment.

Identify Hidden Problems

Many property issues aren't visible during a casual viewing. Our surveyors conduct thorough inspections using professional equipment to identify problems like subsidence, structural defects, damp, timber decay, and electrical issues that could cost thousands to fix.

Negotiating Power

If the survey reveals significant issues, you can use this information to renegotiate the purchase price, ask the seller to carry out repairs before completion, or in serious cases, withdraw from the purchase without losing money.

Budget for Repairs

Knowing about necessary repairs upfront helps you budget accurately. Our detailed reports include advice on approximate repair costs, allowing you to plan your finances properly.

What Surveyors Look For

During the inspection of the property, our chartered surveyors assess:

  • Structure: Foundations, walls, floors, roof structure
  • Exterior: Roof covering, chimneys, gutters, external walls, windows, doors
  • Interior: Ceilings, walls, floors, joinery, fittings
  • Services: Electricity, gas, water, heating, drainage
  • Issues: Damp, timber defects, subsidence, cracking
  • Outside: Boundaries, gardens, outbuildings, drainage

How Long Does a Survey Take?

The inspection typically takes 2-4 hours depending on the property size and survey type. You don't need to be present, but many home buyers find it helpful to meet the surveyor at the end to discuss initial findings.

For RICS Level 2 surveys, you'll receive your detailed report within 3-5 working days. Level 3 building surveys take 5-7 working days due to their comprehensive nature.

Choosing the Right Surveyor

Always choose RICS chartered surveyors. The Royal Institution of Chartered Surveyors sets professional standards and provides regulation. Look for:

  • RICS accreditation and regulation
  • Local knowledge of the London property market
  • Experience with your property type
  • Clear, detailed reporting
  • Professional indemnity insurance

Survey Costs

Survey costs vary based on property value, size, location, and survey type. As a guide:

  • RICS Level 2 Survey: £400-£800
  • RICS Level 3 Building Survey: £600-£1,500
  • Property Valuation: £250-£500

While surveys represent an additional cost when buying a property, they could save you tens of thousands of pounds by identifying serious issues before you commit.

Common Questions

Do I need a survey if I'm buying a new build?

Yes. Even new builds can have defects. A professional inspection provides an independent assessment and peace of mind about build quality.

When should I arrange my survey?

Book your survey after your offer is accepted but before exchanging contracts. This gives you time to review findings and renegotiate if needed.

What if the survey finds problems?

You have several options: renegotiate the price, request repairs, arrange specialist reports, or withdraw from the purchase. Your surveyor can provide expert advice.
