Real renewable survey examples across property types

Short write-ups from real Vertex records, with the room count, electrical setup, and layout references left in because that is usually what matters.

Use these examples to judge how the survey record changes between bungalows, terraces, extension-heavy homes, larger detached properties, UFH jobs, and tighter electrical setups.

Real installer examples

These examples sit below the main case-study hub. They are shorter, but they keep the property shape, room count, and survey constraints visible so installers can compare the types of evidence a renewable survey company should bring back from site.

Detached bungalow - 11 rooms

Bungalow ASHP survey with no-spare-way electrical context

DN36 bungalow with a 60A single-phase intake, no spare ways, and a linked floor plan. This is the kind of property where a short survey report can still miss the point if the electrical limitation is not made obvious for design and install planning.

Detached - 14 rooms

Detached ASHP survey with linked two-storey floor plans

Detached house record with linked floor plans, electrical detail, and two ASHP siting options. The useful part is not just that options existed; it is that the report made both siting routes visible before the installer committed to a design assumption.

Semi-detached - 15 rooms

Extension-heavy ASHP survey with a clear report

Semi-detached house with multiple extensions that had to be shown properly in the floor-plan record. Extension-heavy properties need extra care because a neat address summary can hide a messy heat loss and routing picture.

Mid terrace - 6 rooms

Compact survey with cupboard cylinder and electrical limits

Compact terrace with cylinder dimensions and no spare ways called out clearly. The job needed the report to show tight internal space, equipment position, and electrical constraint in a way the installer could assess quickly.

Detached - 35 rooms

Large multi-floor survey with UFH and three-phase supply

Large complex property with 14 floor-plan captures and a lot of moving parts to keep organised. In this type of survey, the quality issue is whether the report stays navigable once there are many rooms, multiple floors, UFH zones, and several technical checks to hold together.

What this means from property to property

The same survey framework has to flex around different homes. A bungalow may be mostly about access, electrical capacity, and a straightforward floor-plan record. A compact terrace may turn on cupboard space, cable routes, and whether there are spare ways. A large multi-floor property needs careful organisation so the report does not become hard to navigate.

  • Small homes often need clearer evidence on space, access, and electrical limitations.
  • Large homes need stronger room referencing, floor plans, and consistency checks.
  • Mixed construction needs visible notes so design assumptions are not hidden.

The report should reduce interpretation time

Installers do not need another gallery of unlabelled photos. They need evidence tied to rooms, equipment spaces, route decisions, and constraints. These examples show why the way a report is organised can matter as much as the raw survey visit itself.

Quality bar

Every example should make the next step obvious

The next step might be a quote, a design check, a request for missing documentation, or a decision to avoid a weak installation route. The survey record should make those choices easier, not create more questions after the surveyor leaves.

What to compare before choosing a survey partner

When comparing renewable survey providers, check whether the example reports explain the site or simply show that a visit took place. A useful report should make the next action clearer: price the job, request a document, review electrical capacity, challenge a route, or pass the evidence to design.

Evidence layout

Can your team find the key facts quickly?

The strongest proof is repeatable layout. If room records, floor plans, electrical detail, access photos, and constraint notes are always in familiar places, installers waste less time interpreting each new survey.

Scope control

Does the report separate evidence from assumptions?

Clear scope boundaries protect the installer. If something could not be accessed, measured, or confirmed, the report should make that obvious so the team does not carry hidden risk into quotation or design.
