What are SAP calculations and when are they required?

SAP calculations assess the predicted energy performance of a dwelling. They are commonly required for new-build homes, conversions and certain extensions to demonstrate Part L compliance.

What is needed for an on-construction EPC?

The final SAP or SBEM model must reflect the completed building, supported by confirmed construction specifications, test results and commissioning evidence.

What does an Energy Statement include?

An Energy Statement normally describes planning policy, the proposed energy strategy, demand-reduction measures, low-carbon systems, renewable energy and the resulting carbon improvement.

COMMERCIAL ENERGY INSPECTIONS

TM44 air-conditioning inspections.
Stay compliant. Improve efficiency.

Accredited inspections and lodged reports for qualifying air-conditioning systems in commercial and mixed-use buildings.

Request a quote

Identify systems within scope

The effective rated output is considered across the air-conditioning systems controlled by the building owner or operator. Individual units may contribute to a qualifying combined output even where each unit is below the threshold.

Accredited inspection of the installation

The inspection reviews available system information, cooling plant, distribution, terminal units, controls, maintenance and the relationship between installed capacity and building demand. Access requirements are agreed before attendance.

Recommendations that support better operation

The report records the existing installation and identifies practical opportunities to improve efficiency, controls, maintenance and system management. It is an energy inspection rather than a refrigerant leak check or full condition survey.

Portfolio and renewal support

We can coordinate inspections across individual commercial properties or wider portfolios, track the information needed for each building and help clients plan the recurring inspection cycle.

COMMON QUESTIONS

Clear answers.
No guesswork.

01Which systems normally require an inspection?+

In England, Wales and Northern Ireland, air-conditioning systems with an effective rated output above 12 kW generally require regular inspection. Project-specific regional requirements are confirmed before appointment.

02How often is a TM44 inspection required?+

For systems in scope, the interval is generally no more than five years. The report and applicable register should be checked to establish the actual renewal date.

03Is the inspection the same as servicing?+

No. It assesses energy efficiency, sizing, controls and operation. It does not replace maintenance, F-gas duties, refrigerant leak checks or a full mechanical condition survey.

04Can several small units exceed the threshold?+

Yes. The combined effective rated output of systems under the same control can bring a building within scope even where no individual unit exceeds 12 kW.
