Building compliance areas covered

We arrange compliance services for projects in London and in cities and large towns across England.

Compliance coverage across England

We arrange assessments for projects across England, bringing site visits and desk-based work into one enquiry. Start with the site address, the proposed use and the stage you have reached. We use those details to identify the assessment brief and check arrangements for access. An address helps us plan the work; it does not tell us everything that the project will need.

Coverage includes new homes, conversions, existing workplaces and occupied property. A drawing-based calculation can often begin before the building is ready for a visit. Testing needs a suitable site condition and someone who can provide access. Tell us about restricted working hours, occupied rooms or a remote location when you enquire so these practical points are included in the scope.

Why location changes the planning report

  • Local plans set the policy context

    The National Planning Policy Framework sets national planning policy within a plan-led system. Local planning requirements differ between councils because their development plans and relevant policies differ. An energy or sustainability statement should identify the policies relevant to that proposal rather than reuse the policy section from another site. We ask for the application reference and any policy advice already received.

  • Validation lists shape the submission

    Planning practice guidance on making an application explains national and local information requirements, including local lists. Councils can therefore ask for different supporting information, subject to the guidance on relevance and proportionality. A report prepared for one authority may omit evidence requested by another. Send the current validation request so the assessor can address the actual information sought.

  • Conditions define a later task

    The National Planning Policy Framework addresses the use of planning conditions. The conditions attached to an individual permission can create a specific evidence task. Local requirements and the wording of the decision differ between projects and councils. Supply the whole condition, its reason and any approved documents. A report title alone cannot show whether the requested matter has been answered.

What stays national across England

The Building Regulations provide the national framework in England. Moving a proposal between councils does not create a separate local set of Building Regulations. The Approved Documents give guidance on ways to meet relevant requirements. Which provisions apply still depends on the work, building use and applicable transitional arrangements, so we establish the project circumstances before specifying evidence.

For example, Approved Document E addresses resistance to sound, while Approved Document F addresses ventilation. A conversion and a new home may need different assessment scopes even on neighbouring sites. National rules do not mean every building needs an identical bundle of tests. The assessment must follow the applicable requirement and the design that will actually be constructed.

How location affects the evidence brief

A home beside an existing noise source

Planning practice guidance on noise calls for attention to the effects of noise on development. A planning assessment might examine the surrounding sound environment and proposed mitigation. The local policy context and any condition differ between councils. Give the assessor the site layout, proposed room uses and the authority’s request before arranging monitoring.

Tell us if access to a boundary depends on a neighbour, if the site cannot be left unattended, or if the layout is still changing. These details affect how a visit is planned and whether further information will be needed. They are practical project facts, rather than assumed characteristics of a town or district.

Flats within an existing building

For a conversion, a planning noise report and a sound insulation test answer different questions. Approved Document E describes the building sound insulation guidance; planning practice guidance on noise concerns the planning assessment. We keep the two purposes clear so evidence prepared for one task is not presented as automatically completing the other.

Existing finishes, occupied adjoining rooms and the proposed sequence of work can affect the assessment plan. Send drawings showing the separate homes and any commercial space. If the design changes after a report is issued, identify the revision so the assessor can decide whether the conclusions still describe the proposal.

What to send with a location enquiry

  • The full site address and the correct application reference, if one exists. Distinguish the correspondence address from the building where a visit is needed. Include a plan where the entrance or site boundary would be difficult to identify.
  • The current drawing set, intended use and project stage. Identify whether you are seeking an initial design assessment, evidence for an application, a response to a condition or completion-stage testing. This helps avoid ordering a report for the wrong decision.
  • The actual request from the planning officer or Building Control, together with previous reports on the same subject. We can then describe the intended deliverable clearly and identify missing inputs before work is booked.
  • Access instructions and any restrictions affecting a visit. Explain who controls keys, whether occupants need notice and which spaces remain unfinished. We will confirm the proposed arrangements rather than infer site readiness from a location name.
