Energy Performance Certificate (EPC) for business

Similar to the multi-coloured sticker on new appliances, an Energy Performance Certificate (EPC) tells you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient).

Cost Insights

EPCs let the person who will use the building know how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be.

Improvement Highlights

The commercial EPC will also state what the energy-efficiency rating could be achieved if improvements are made and highlights cost-effective ways to achieve a better rating.

Compliance Updates

From 1 April 2018, landlords of non-domestic private rented properties (including public sector landlords) may not grant a tenancy to new or existing tenants if their property has a rating of band F or G as shown on a valid Energy Performance Certificate (EPC) for the property.

From 1 April 2023, landlords must not continue letting a non-domestic property which is already let if that property has an EPC rating of band F or G.


The penalties which could be applied to the landlord if there are found to be non-compliant are:

  • Less than three months in breach – Up to either £5,000 or 10% of the rateable value to a maximum of £50,000, whichever is the greater
  • More than three months in breach – Up to either £10,000 or 20% of the rateable value to a maximum of £150,000, whichever is the greater

What we can do to help

Through our Savings Opportunities Report Tool (SORT) we can advise where improvements can be made to improve an EPC rating – If there is no valid commercial EPC or it is rated F or worse and the property lease is due for renewal then action is required to implement energy improvements to the property.

If the EPC is rated as an E and will still be valid at the time of the next lease renewal then there is no immediate need to address. However, from April 2023 all leased properties with a valid EPC must have a rating of E or better so plan now for the inevitable. Just because it is E now does not mean it will be at the next EPC renewal.

Commercial EPCs are valid for 10 years from when issued.

This service can be added on to an energy audit with the SORT report. We are able to assess a building’s current EPC level and determine, if possible, how to improve it. This is particularly important for buildings that have a target to improve their EPC by a certain date.

"Absolutely spot on & extremely satisfied. The new LED lighting offers fantastic coverage which is exactly what was required"

"The installers were excellent and delivered exactly what was specified, everybody has commented very positively within the business and will be happy to recommend you to other departments."

Branch Manager, Colchester

“We had been planning the full refit of our lights for a couple of months and having chosen SaveMoneyCutCarbon the fitting team were with us for a couple of weeks before Christmas."

“They were able to come in after the school activities had finished in the afternoon. The Team were very amenable to working around any occupational restrictions we had with clubs and so on. They were a cheerful bunch and left the school tidy everyday with the furniture returned to its usual positions. There were a few changes to the fittings etc. that were noted during the fitting from the original survey and these were put in place without any problems."

Martin Blake, Business Manager at Nicholas Hawksmoor

“LEDs were the next logical step after our earlier lighting improvements but we could not at first secure the budget, given other pressing curriculum needs. However, we worked through the Diocese with SaveMoneyCutCarbon to take the opportunity to apply for Salix funding and the whole process went pretty smoothly."

"Overall, the standard of work from SaveMoneyCutCarbon was impressive. After SaveMoneyCutCarbon secured the interest-free loan, they moved very quickly to install the LED lighting, ensuring that the work was completed during the summer holidays, which was excellent. The early impressions of the new lighting are very positive, particularly in the library area and staff room. I’m sure we will see more benefits as the winter draws in.”

Anthony Murray, Head Teacher, St Bede’s

“The installation team was very professional and the managers responded positively to requests for changes as the project was delivered."

"There was a strong business case for choosing LED lighting and we’re looking forward to reduced costs over many years. The lighting is much improved, a lot brighter and clearly better quality, which I’m sure we’ll notice even more as winter draws in.”

Beverley O’Shea, Business Manager, Bishop Challoner School

LED lighting and lighting controls certainly ticks the boxes and is really is a sound investment that simplifies carbon reduction."

"Lighting controls in particular are a great asset as it is difficult to rapidly change people’s attitudes to switching off lighting."
