RICS Level 2 Survey in BA7

Castle Cary has a designated Conservation Area protecting the character of the town centre and surrounding streets. Properties within the Conservation Area include Georgian townhouses on Fore Street, Victorian limestone terraces, and listed farm buildings converted to residential use. Buying within or adjacent to a Conservation Area has planning implications: permitted development rights are reduced, and some external alterations require specific consent from Somerset Council.

Our survey report notes Conservation Area status and highlights where elements of a property's condition are likely to require specialist materials or Listed Building Consent-compliant methods to repair. Replacing original sash windows with uPVC, for example, is not permitted in most Conservation Areas without specific consent - and installing them without consent can create a legal liability that affects future sale and mortgage valuability.

For properties that are themselves listed (Grade II or above), our RICS Level 2 Survey remains a useful starting point but we will often recommend upgrading to a RICS Level 3 Building Survey. Listed buildings have no standard construction - each one is a product of its own history of alterations, repairs, and adaptations, and a Level 3 survey gives a more detailed account of hidden condition that a Level 2 is not designed to reach.

• Conservation Area - reduced permitted development rights affect what can be altered
• Original features (sash windows, stone mullions, slate roofs) must be maintained in kind
• Lime-based repair materials required - Portland cement will cause damage
• Tree Preservation Orders may apply within or adjacent to the Conservation Area
• Sale and mortgage both affected if unauthorised works have been carried out

A significant proportion of BA7 properties use private drainage systems rather than mains sewer. Septic tanks and package treatment plants are common in the villages and hamlets outside Castle Cary town centre. Our Level 2 Survey notes whether the property appears to drain to a private system and recommends a drainage investigation by a specialist contractor where we cannot confirm the drainage route or condition. The current drainage regulations (General Binding Rules for small sewage discharges in England) mean that many older septic tanks discharging directly to a watercourse are non-compliant and must be upgraded - a cost that can run to £3,000 to £10,000 depending on the system type and ground conditions.

Oil-fired central heating is the dominant heating system in rural BA7. Our surveyors record the approximate age and condition of the oil boiler, the state of the flue, and the condition of the oil tank and its bunding. An oil storage tank that lacks adequate secondary containment (bunding) is non-compliant with current regulations and will need to be upgraded or replaced. Domestic oil tank replacement costs between £800 and £2,500 depending on tank size and access.

Where properties have private water supply - less common in BA7 than in more remote rural areas but present in some properties adjacent to agricultural land - we flag this in the report and recommend a water quality test. Mains water supply is available throughout most of the BA7 postcode but always confirm the property's supply arrangement with the vendor before exchange.

On every BA7 inspection, our surveyors follow a structured methodology designed for period stone and rural properties. We assess the roof covering from ground level using binoculars - recording slipped, cracked, and displaced tiles or slates, the condition of valley flashings and lead work, and the state of chimney stacks and parapet gutters. Parapet gutters behind stone parapets are a known failure point on Victorian limestone townhouses: they corrode or crack without visible external signs, and the resulting water ingress can penetrate party walls for years before it becomes visible internally.

Internally, we take moisture meter readings at regular intervals across all ground floor walls - typically every 300mm on walls with any external exposure. Limestone walls that have been lined internally with plasterboard or dry lining can conceal damp penetration; our surveyors note internal lining and recommend investigation behind it where external wall conditions indicate risk. Ground floor solid concrete slabs in converted agricultural buildings are assessed for damp-proof membrane presence and condition.

All accessible roof spaces are inspected. In older BA7 properties, original roof structures are often of interest: king post trusses, crown post trusses, and collar-rafter frames all appear in the older building stock. Our report records the structural frame type, its apparent condition, any visible signs of beetle infestation (Death Watch Beetle is a risk in pre-1900 Somerset properties with oak structural timbers), and any evidence of past water ingress tracking through the roof covering.

• Lime pointing condition assessed across all elevations
• Moisture meter readings at regular intervals on all ground floor walls
• Roof covering inspected from ground level using binoculars
• Parapet gutters and hidden valley details specifically noted
• Timber structural frame inspected for beetle infestation where accessible
• Private drainage and oil tank condition noted where present
• All services (electrical, gas/oil, water, drainage) recorded with condition observations
