In-House Energy Services
At Metters & Wellby, we offer a full range of energy assessment services directly through our in-house team—eliminating the need for third-party consultants and ensuring a seamless, integrated process.
Our qualified ABBE Level 3 Domestic On-Construction Energy Assessor provides:
SAP Calculations (Standard Assessment Procedure)
A government-approved method used to assess the energy performance of new-build homes and renovated homes. It’s required to demonstrate compliance with Part L of the Building Regulations and forms the basis for producing an EPC.
EPC (Energy Performance Certificate)
A certificate showing the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It’s legally required when a new home is constructed or sold.
Energy Statements
Required by Cornwall Council during planning, these reports show how a proposed development will meet local energy and carbon reduction targets. They include predicted energy use, CO₂ emissions, and proposed sustainability measures.
Because we provide these services in-house, we can embed energy performance thinking right from the earliest design stages—supporting both compliance and sustainability without delays or added cost.

Ask The ExpertsFrequently asked questions
What is an Energy Statement and when do I need one?
An Energy Statement demonstrates how a proposed development will meet relevant energy and carbon-reduction requirements. They are commonly required as part of planning applications for new residential development in Cornwall. Our Planning Consultancy service can coordinate this with the wider application where required.
What’s the difference between an Energy Statement, SAP calculation and EPC?
They serve different purposes and can be required at different stages. An Energy Statement is generally used during planning, while SAP calculations assess compliance with Building Regulations and contribute to the EPC for a new home. Our Building Regulations & Construction service covers the technical stage of a project.
Why is it useful to have energy assessment carried out by the same team designing the building?
It means energy performance can inform the design as it develops rather than being considered separately later. Changes to glazing, insulation, heating or renewable technologies can be coordinated directly with the architectural design, particularly on bespoke energy-efficient homes and major renovation projects.
