Bungalow survey: common problems and what to look for
Bungalows have a different defect profile from two-storey houses. The smaller wall-to-roof ratio means roof condition matters proportionally more; the single-storey footprint means more roof per square foot, more drainage runs, and shallower foundations relative to wall length. Most UK bungalows are 1930s–1970s and now in a renewal cycle.

Single-storey UK bungalows typically have shallow strip foundations, large pitched roofs (sometimes with attic conversion potential), and longer drainage runs proportionally than houses. Flat-roof bungalows are less common but exist, they introduce a different long-term renewal pattern. Walls are typically cavity from the 1950s onwards.
Common defects to expect
These items are routine for the property type. Most are renegotiation items, not deal-breakers. The survey's job is to flag which apply to this specific property and which have already been addressed.
- Roof at end of life (more roof per square foot than houses)
- Drainage runs aged and at end of life
- Shallow foundations vulnerable to clay shrink-swell movement
- Attic conversion (if done) often without Building Regs
- Cavity wall insulation issues
- Asbestos cement roof tiles or sheets on outbuildings
- Original kitchen and bathroom often unrenewed
What the survey should cover
- Roof structure and covering condition (proportionally more important than for houses)
- Foundation condition and any movement at corners or above openings
- Drainage condition, long runs and many manholes
- Attic conversion, if present, against Building Regs status
- Cavity wall insulation status
Which survey level to book
RICS Level 2 is adequate for well-kept post-1960 bungalows. Level 3 for older bungalows (pre-1960), any with attic conversion, or where the surveyor flags movement.
For a deeper comparison see Level 2 vs Level 3 survey.
Construction-specific risks
Bungalows on clay soils sit on shallow strip foundations and are more susceptible to clay shrink-swell movement than two-storey houses with deeper foundations. The roof is the largest single proportional cost over a bungalow's life. Attic conversions on bungalows are often informal and may lack Building Regs sign-off.

What to check before offering
- →Get the roof age and renewal history
- →Check foundation condition particularly on clay-soil sites
- →Read the EPC, bungalows typically band lower than houses for the same square footage due to roof-to-floor ratio
- →Confirm any attic conversion has Building Regs sign-off

Are bungalows more prone to subsidence?
Bungalows on clay soils with shallow strip foundations are more susceptible to clay shrink-swell movement than two-storey houses with deeper foundations. The risk is well-managed, bungalow surveys should specifically check for clay-driven movement.
How much does a bungalow roof cost to replace?
More than a same-square-footage house because of the larger roof area. A typical 3-bed bungalow tile roof replacement runs £8,000–£18,000 depending on tiles, complexity and any insulation upgrades.
Should I convert the loft of a bungalow?
Possible on most bungalows but needs proper structural design, bungalow rafters were typically not sized for habitable loft loads. Permitted Development rights apply in many cases but Building Regulations approval is essential.
Are bungalows harder to mortgage?
No. Bungalow construction is mainstream-mortgageable. Lenders rarely make distinctions on bungalow vs two-storey house at the construction-type level.
