RICS Level 2 Survey in Collier Street

Collier Street sits in the middle of Islington, where the housing mix is dominated by flats, many created within converted Georgian and Victorian buildings. In the wider N1 postcode district, 86.7% of homes are flats, and a large share date from the pre-1919 period, so a professional survey before you buy is a sensible step. These characterful older properties, in one of London's liveliest neighbourhoods, can hide defects that simply do not show up at a casual viewing. Our surveyors regularly inspect homes on Collier Street, and on nearby roads including Pentonville Road and York Way, so we know this local housing stock well.

In this part of Islington, our RICS Level 2 surveys are particularly useful because they deal with the construction issues we see time and again. The local London Clay geology can lead to subsidence and heave, as clay soils swell in wet weather and shrink in dry spells, placing pressure on foundations. That matters even more with older buildings that have shallower foundations, or homes close to the mature trees around Collier Street. We have seen cases here where roots from established London plane trees have affected both drainage runs and foundations, the sort of problem an experienced surveyor in this locality knows to look for.

Being close to Regent's Canal and Battlebridge Basin, this area also calls for a careful look at flood risk. Our surveyors assess drainage, look for signs of water ingress, and build up a clear picture of the property's condition. We inspect external ground levels, drainage grilles, and any about previous flooding in the building. With prices in Collier Street changing over recent years, and values 55% down from their 2023 peak of £975,000, it is important to know exactly what you are buying in a market that is still competitive.

Across Islington, and especially around Collier Street, we see certain defects come up again and again. Knowing that before the survey can make the findings easier to understand and help you decide what matters most in any negotiation with the seller. We have inspected hundreds of flats in this part of the borough, from Collier Street itself to nearby developments, and that gives our team a solid sense of the defect patterns typical of the local housing stock.

Damp turns up regularly in older properties here. Homes built before 1919 often have no modern damp-proof course, or the original protection has failed with age. Rising damp and penetrating damp can both cause structural damage and create health concerns if left alone. Our surveyors use visual checks and moisture meters to assess both the extent of the problem and its likely cause. In conversions, we often find damp around window frames, where original single-glazed windows have let in water over decades of exposure to London's weather.

Services are another frequent issue. In converted Victorian and Georgian properties, electrical and plumbing systems often need updating to meet current safety standards. Quite a few flats still retain wiring from the early to mid-20th century, and that may not be suitable for modern electrical demand. We regularly come across old fuse boards, too few socket outlets, and wiring that falls short of Part P of the Building Regulations. Lead pipes and old galvanised plumbing are also common. Where we find these issues, we flag them clearly in the report, recommend what should be done, and say whether the defect amounts to an immediate safety concern.

• Rising and penetrating damp
• Outdated electrical wiring
• Old plumbing systems
• Roof defects and leaks
• Structural movement cracks
• Missing or damaged insulation
• Asbestos in pre-2000 properties
• Windows and door deterioration
