Homebuyer surveys tailored to Cardiff's terraces, bay-fronted Edwardian houses, and modern Bay apartments








Cardiff's housing stock spans everything from Victorian Pennant sandstone terraces in Canton and Splott to Edwardian bay-fronted houses across Roath and Pontcanna, through to modern apartments around Cardiff Bay. With an average house price of £268,000 and around 146,000 households across the capital, a RICS Level 2 Survey gives you a clear, structured assessment of visible defects before you commit to a purchase — flagging issues from damp penetration to roof defects using an easy-to-follow traffic-light rating system.

Cardiff is the Welsh capital, but its residential streets tell a story shaped by the coal export boom of the mid-nineteenth century. Rapid house-building between 1860 and 1914 produced thousands of workers' terraces in Splott, Grangetown, Adamsdown, and Canton — constructed from locally quarried Pennant sandstone with lime mortar joints, Welsh slate roofs, and minimal foundations. These properties now face the effects of over a century of weathering, Welsh rainfall, and — in many cases — poorly considered modernisation. The Level 2 survey systematically inspects these elements and flags visible problems before they become expensive surprises.
The Level 2 format uses a condition rating system — green (no immediate concern), amber (repairs needed but not urgent), and red (serious defects requiring attention). For a standard Cardiff terraced or semi-detached house in fair condition, this level of reporting covers roofing, walls, windows, damp, drainage, and services. It identifies the severity of each defect and recommends further investigation where necessary, giving you leverage to renegotiate the asking price if significant issues are found.
Cardiff sits within the jurisdiction of Natural Resources Wales rather than the Environment Agency, and flood risk mapping, planning constraints, and conservation area designations work differently here than in English cities. The city has 27 conservation areas — including Cathedral Road, Pontcanna, and parts of Roath — where restrictions on external alterations apply. Your surveyor will note any conservation area status and flag planning considerations that could affect your renovation plans or future maintenance obligations.

Prices based on a standard 3-bed property. Cardiff pricing sits slightly below the national average, reflecting the Welsh property market. Larger or more complex properties will cost more.
The RICS surveyors we work with across Cardiff live and operate locally. They know the difference between a well-maintained Pontcanna terrace and a tired Cathays student rental, can spot the signs of poorly repointed Pennant sandstone, and understand how the city's river corridors affect individual properties. Their local knowledge ensures the survey report reflects the specific risks and conditions that apply to Cardiff — not a generic checklist written for a different kind of housing stock.

Enter the property details — address, type, rough age, and number of bedrooms. You'll receive a price straight away. If a Level 2 survey is suitable for the property, you can book and pay online. We contact the seller or their estate agent within 24 hours to arrange access.
A local RICS surveyor visits the property and carries out a full visual inspection. For a typical Cardiff terrace or semi-detached house — the most common types across the city — expect the visit to take 1.5 to 3 hours. Larger properties in areas like Cyncoed or Lisvane, or those with extensions and outbuildings, may take longer.
The completed Level 2 report arrives within 2 to 6 working days. It covers every inspected element with a condition rating, highlights urgent repairs, and recommends further investigation where needed. Our bookings team is available to talk through the findings and help you arrange any follow-up services such as a specialist damp survey or roof inspection.
Cardiff grew faster than almost any other British city during the late Victorian period. The Bute Docks turned a small market town into the world's largest coal-exporting port by the early 1900s, and the population surged from around 18,000 in 1851 to over 164,000 by 1901. That explosive growth produced entire neighbourhoods of workers' housing in a matter of decades — streets of tightly-packed Pennant sandstone terraces in Splott, Adamsdown, and Grangetown, built quickly to house dockers, steelworkers, and railway labourers. These properties share common characteristics: solid walls, shallow strip foundations, rear extensions added informally, and lime mortar that has weathered unevenly over 120-plus years.
After the First World War, Cardiff's suburban expansion pushed north and west. Interwar semis in Whitchurch, Llanishen, and Rhiwbina introduced cavity walls, wider plots, and integral garages — construction methods that present different risks from the inner-city terraces. Post-1960 estates in Pentwyn and Llanedeyrn brought system-built construction and flat-roof designs that bring their own maintenance challenges. The Level 2 report is calibrated to catch visible problems across all of these eras, rating each building element so you can see at a glance which parts of the property need attention before or shortly after purchase.

At just 0.14% of Cardiff's average property price, a Level 2 survey is one of the lowest-cost safeguards in any home purchase. The report covers every visible part of the property and flags defects you might not spot during a viewing — cracked render hiding damp penetration, sagging roof timbers concealed by a loft conversion, or failing drainage behind a freshly landscaped garden. For a typical Cardiff terrace, even a single amber-rated item like defective guttering (£800–£1,500 to repair) or failing window seals (£1,000–£3,000 to replace) gives you grounds to renegotiate the asking price by more than the survey fee.
Skipping a survey can prove far more costly. Replacing a Welsh slate roof on a Cardiff terrace runs £8,000–£14,000. Treating damp across the ground floor of a solid-walled Grangetown house costs £3,000–£8,000. Repointing an entire Pennant sandstone facade in lime mortar can reach £10,000–£15,000. This type of survey does not guarantee it will catch every hidden defect — it is a visual inspection, not a structural strip-down — but it will identify the visible warning signs that prompt further investigation before completion.

Level 2 surveys in Cardiff start from around £380 for a standard 3-bed terraced or semi-detached house. Prices increase with property size and value — expect £500–£700 for larger homes in Cyncoed, Lisvane, or Radyr. Cardiff pricing sits slightly below the national average of around £395 because Welsh property values are lower than the English average. The exact cost depends on the number of bedrooms and the property's market value at the time of booking.
For a Victorian terrace in broadly fair condition — one that has not been heavily altered or extended, with no visible signs of structural distress — a Level 2 survey provides a useful overview of the property's condition. The traffic-light rating system highlights any areas of concern. If the surveyor finds indicators of deeper problems, such as significant cracking, major damp, or signs of movement, the report will recommend upgrading to a Level 3 investigation for those specific areas. Many buyers in Canton, Roath, and Pontcanna start with a Level 2 and only move to a Level 3 if the initial report raises red flags.
A Level 2 inspection on a standard Cardiff terraced house takes between 1.5 and 3 hours on site. Semi-detached and detached properties in the northern suburbs — Whitchurch, Llanishen, Heath — tend to be larger and may take up to 3.5 hours. The written report is produced within 2 to 6 working days after the inspection. Level 2 surveys are quicker than Level 3 because the surveyor does not open up the building fabric — it is a thorough visual inspection rather than an intrusive investigation.
The survey itself does not include a formal flood risk assessment, but your RICS surveyor will note any visible evidence of past water ingress, staining, or flood damage. Cardiff has the highest flood risk of any local authority area in the UK, with around 33,000 properties predicted to be at risk by 2050. Properties near the River Taff through Pontcanna, Riverside, and Canton, or near the River Ely through Caerau and Ely, face the greatest exposure. If the surveyor notes flood-related concerns, you can request a separate environmental search through your solicitor for detailed flood mapping data from Natural Resources Wales.
Damp is one of the most commonly flagged issues in Cardiff Level 2 reports. The city receives roughly 1,150 mm of rainfall annually, and many inner-city properties have solid Pennant sandstone walls that lack cavity insulation. The surveyor will use a handheld moisture meter on accessible walls and note any visible damp patches, mould, or staining. If damp readings are elevated across multiple rooms, the report will give a red or amber rating and recommend a specialist damp investigation. Penetrating damp through deteriorated mortar joints is especially common in Cardiff terraces built before 1919.
A Level 2 survey is well suited to most purpose-built Cardiff Bay apartments. These were largely constructed during the 1990s and 2000s Bay regeneration and use standard modern construction methods. The survey covers the apartment itself — walls, ceilings, floors, windows, and services — along with a brief assessment of visible common areas. If the apartment is inside a converted dock warehouse or industrial building, the construction is more complex, and a Level 3 may be more appropriate to assess how the conversion was carried out structurally.
Absolutely. The condition ratings in a Level 2 report give you documented evidence to present to the seller or their agent. If the report flags red-rated defects — a failing roof, significant damp, defective drainage — you can request a reduction in the asking price to cover the estimated repair cost. In Cardiff's market, where the average house price is £268,000, even a modest negotiation saving of £3,000–£5,000 vastly outweighs the survey fee. Your surveyor's findings carry professional weight that a verbal observation during a viewing does not.
A Level 2 survey is a visual inspection. The surveyor examines all accessible parts of the property and rates each element using a traffic-light system — green, amber, or red — with notes on the defect and what action to take. A Level 3 survey goes further: the surveyor opens up the building where possible, lifts floorboards, enters roof voids, and investigates defects to their source. For standard Cardiff homes in reasonable condition — a post-war semi in Whitchurch or a well-maintained Edwardian terrace in Penylan — a Level 2 gives you the information you need. For older properties with visible structural concerns, or buildings that have been significantly altered, the Level 3 is the right choice.
