RICS Level 2 Survey in AL2

AL2’s housing stock stretches across several decades of building. The postcode district includes 10,390 addresses, made up of 8,193 houses and 2,197 flats. In the wider St Albans postcode area, the mix is 32.5% terraced properties, 24.9% flats, 23.6% semi-detached, and 19.0% detached. That range means our surveyors come across a broad spread of construction types across the AL2 villages, and each one brings its own inspection priorities.

In London Colney, Bricket Wood and Park Street, older terraced and semi-detached homes usually call for close attention to the roof covering, chimney condition, and external fabric first. Houses from the 1930s and 1940s often still carry original clay plain tiles or concrete tiles that have reached the end of their service life, so they may need patch repairs or a full re-covering within the next 5 to 10 years. From our inspections of post-war semis across London Colney, deteriorated roof coverings come up most often as a Condition 3 issue, and concrete tiles from the 1960s and 1970s are at, or nearing, expected service life. We set that out clearly in the report, so you can see what spending lies ahead.

Ground-floor damp keeps cropping up in older properties across this part of Hertfordshire. Where raised external ground levels have bridged original damp-proof courses, or where solid floors were laid without a membrane, moisture can work its way into the base of walls. Our inspectors take damp meter readings at regular points around the ground-floor perimeter walls and note any higher readings with the recommended next step.

AL2 also has plenty of extensions and conversions, as many owners have added rear extensions, loft conversions, or garage conversions over time. Our inspectors look at whether these appear to have been done with proper building regulation compliance in mind, checking insulation, fire separation, and structural connections, then flagging anything where further legal verification seems sensible.

The villages within AL2 have grown at different times. London Colney expanded strongly after the war, with council housing and private semi-detached homes built through the 1950s and 1960s. Bricket Wood and Park Street include older cottage and villa stock, plus interwar development and newer infill. That mix of ages means buyers need to know which era their specific property comes from, because that shapes the survey priorities.

Properties built between 1945 and 1980 are usually where a RICS Level 2 survey gives the most useful information. They are old enough to have built up maintenance backlogs, roof timbers nearing the end of expected life, boilers long past their normal replacement cycle, electrical systems untouched for decades, yet those problems are not always obvious without professional inspection.

Post-1980 properties in AL2 are generally easier to survey, though later additions such as extensions, conservatories, and loft conversions can still bring compliance and quality issues. Our inspectors consider each addition on its own merits, noting where the work looks well executed and where more investigation or legal verification may be needed.

• Pre-1919 properties: check roof structure, chimney condition, solid wall damp performance, and timber floors
• Interwar properties (1919-1945): check roof coverings, steel windows, external render or pebbledash condition
• Post-war housing (1945-1980): check electrical systems, boiler age and condition, cavity wall insulation, and drainage
• Post-1980 properties: check extensions and loft conversions for building regulation compliance and quality

From our experience, the two AL2 property types where we most often suggest a Level 3 survey are homes built before 1919 and properties with substantial extensions or loft conversions added in the 1980s-2000s. The first group often needs a closer look at original construction methods, while the second can vary a lot in quality, so a more detailed survey gives buyers stronger protection before they commit.

The St Albans postcode area recorded 2.7k property sales in the 12 months to December 2025, down 12.5% and 415 transactions from the previous year. That fall in volume reflects the wider effect of higher mortgage rates on activity, not a loss of appeal in the area. AL2 still has some of the strongest transport links in Hertfordshire, with the M25, M1, and rail connections into London, and demand from London-commuting buyers remains firm.

The £500k-£750k band made up 27.3% of St Albans postcode sales, or 741 properties, so it is by far the busiest price range. This is where most AL2 semi-detached and terraced stock sits for buyers. In this bracket, mortgage commitments are often substantial, and the financial hit from undisclosed defects can be large. At this level, a survey is proportionate due diligence.

The difference between AL2 prices and London prices keeps the postcode attractive to buyers priced out of inner and outer London who still want strong city access. That steady demand from London-focused buyers helps put a floor under AL2 property values, and it also means well-kept homes in the area tend to sell quickly once listed.
