Part L and energy-compliance consultancy

Joined-up advice when several requirements interact or a design needs a cost-conscious route to compliance.

Low-energy home with solar panels and heat pump being reviewed for Part L compliance

Overview

Some projects do not need another isolated calculation. They need an energy strategy: an understanding of how fabric, glazing, junctions, services, ventilation, overheating and renewables interact, and which changes are proportionate to the design.

Good to know

Project requirements vary by building type, location and timing. Send us the project information and we will confirm the right assessment route before providing a quotation.

Particularly useful for

  • Designs struggling to achieve the applicable standard
  • Architects seeking early technical guidance
  • Projects comparing compliance strategies
  • Complex extensions, conversions and new dwellings

Our approach

  1. 01

    Establish the regulatory route, constraints and project priorities

  2. 02

    Review the interacting calculations and specifications

  3. 03

    Compare focused, buildable options

  4. 04

    Coordinate the selected strategy through the relevant assessment outputs

What is included

An agreed review of the energy-compliance strategy, the assumptions driving the assessment and proportionate options for the design team. The work is scoped around the unresolved issue, with relevant calculation outputs coordinated where included in the appointment.

Information to send

Send drawings, specifications, existing calculations and any comments from Building Control. Include the project type, application history, stage and the design or cost constraints you need to protect. Highlight the decision that is preventing the project moving forward.

Scope, fees and timing

The assessment route depends on the work and the regulatory standards applying to it. New dwellings, conversions and extensions should not be treated as interchangeable. This page covers coordinated domestic consultancy; the SAP service page covers commissioning the core dwelling calculations.

Based in Lincolnshire, we support architects, builders, developers and homeowners across the county and throughout England. Most calculation-led work can be reviewed from suitable digital drawings. Send the project location, stage and required date so we can confirm the scope, fee and programme before you instruct us.
