How Much Do SBEM Calculations Cost? Sustain Quality

When it comes to SBEM calculations, we get a lot of enquiries as to how much they cost. As you might have guessed, this figure will vary depending on the type of project and the individual requirements of the project.

The purpose of this article is to give you a general idea of
cost to help best prepare you for your budgeting before embarking upon your
building process.

Why Do You Need A SBEM Calculation?

SBEM calculations are needed in order to comply with Building
Regulations Part L2. If you are building, refurbishing, or extending any
commercial premises over 50m2, your Building Control Body will request a

The SBEM calculation then produces a BRUKL Report, showing an
energy efficiency rating for your building. In order for your building to pass
the Building Regulations Part L2, your SBEM report certificate should show:

  • A Building Emission Rate (BER) lower than the Target Emission Rate (TER)


‘As Design’ Stage

We offer SBEM calculations during both stages of the
construction process. During the design stage, we carry out a SBEM calculation
prior to the construction work being carried out.

This shows that the building meets the Target Emission Rate
(TER) for efficiency.

A SBEM calculation at this stage would cost anything in the region of £350-£5,000 depending on the size of the development.

‘As Built’ Stage

Once works have been completed (the ‘as built’ stage), we will
carry out another SBEM calculation.

The ‘as built’ SBEM calculation should be reflective of the
calculation carried out during the ‘as design’ stage.

We aim to provide a detailed and comprehensive ‘as design’
SBEM calculation so that your work can be signed off by Building Control in a
smooth and efficient manner.

A SBEM calculation at this stage would cost anything in the
region of £350-£5,000 depending on the size of the development.

‘As Design’, ‘As Build’, Or Both?

We recommend that you get your SBEM completed as early as
possible. We would suggest that you involve your assessor as part of the Design
team in order to identify any shortfalls before they become a problem.  

In an ideal world, it would be great to stay with you
throughout the process so that we can complete the SBEM calculations at both
stages of the build. However, we understand that certain factors don’t allow
for this.

For example, you might sell the building(s) before works
have been completed. In this instance, it would be up to the new owner to
organise a SBEM calculation. This may be months or even years down the line.

We recognise that there is a need for flexibility and our
core aim is to assist and support in the smooth running of your building project.

What Are You Paying For?

Essentially, you are paying for our expertise, resources and time. We’re highly skilled in the latest, government-approved energy assessment software and a large part of our work involves careful and strategic use of this software.

Factors Affecting Cost Of A SBEM Calculation

One of the main reasons that we suggest working closely
alongside the design team is to avoid any factors that could affect the cost of
a SBEM calculation.

Major changes in design may require another SBEM
calculation to be carried out, which could take up more time and resources on
our part.


The subject of costing is quite a difficult issue to
address. The size and individual requirements of a project will inevitably
differ greatly.

Commercial and residential projects also have their differences regarding size and requirements. Our Cole Gardens project will have different cost implications for a much larger project, for example.  

With that being said, we hope that this post will give you a
general guide to how much SBEM calculations cost in the commercial sector, and any
unexpected costs that may affect the overall price of the calculation.
