Your first step toward cheaper bills, greater comfort, and a lower carbon impact is a BHESCo energy survey

Why do I need an energy survey?

At BHESCo we believe in taking a ‘fabric first’ approach to improving the energy performance of a building. This means that property owners should seek to maximise the energy efficiency of their building before considering any renewable energy solutions.

It makes no sense to begin installing solar panels, heat pumps, or battery storage until all efforts have been made to minimise heat loss and energy waste.

And in order to identify the most cost-effective opportunities for improving the energy efficiency of a property it is vital to first gain a good understanding of the current heat and power demands.

For this reason, BHESCo energy survey should be the first phase of any planned building improvements, underpinning every stage of your future energy performance strategy.

What is included with a BHESCo energy survey?

A detailed analysis of heat loss and energy waste

Our bespoke energy survey will provide a thorough and detailed examination of every aspect involved with heating and powering your property.

Our Energy Saving Team will conduct an on-site survey to capture the relevant data. We will analyse your historic energy bills to gain an understanding of your energy usage and to identify times of peak demand.

We will produce a detailed report recommending the most cost-effective solutions to remedy areas of significant heat loss and energy waste.

Recommendations and future costs

Our report will also measure and compare the anticipated reduction in demand that we would expect from installing different types of energy saving measures and other green energy solutions.

This enables you to draw conclusions about which combination of technologies will best meet the heat and power requirements of your property, as well as being able to consider upfront cost and future savings projections to help you make the best decision.

Accessing finance for your energy improvements

Furthermore, our expertise and familiarity with national energy policy can identify any financial support  available to reduce the cost of your energy improvements. For example, during previous projects we have helped our customers to access such subsidy schemes as the Feed-In-Tariff and the Renewable Heat Incentive. Under the current subsidy regime this could include the Boiler Upgrade Scheme or the Local Area Delivery scheme. 

In some cases, we can also help customers to take advantage of tariff offers from energy suppliers who agree to purchase excess renewable electricity that is produced from your micro-generation system.

Where applicable we can make our ‘Pay As You Save‘ financing available to help customers meet the upfront cost of their planned improvements.

What happens after the energy assessment?

Once our Energy Saving Team have concluded their on-site survey they will send you a report within 14 days.

The report will include details of where you are wasting heat and power and recommend various solutions for improving energy performance.

Once you have selected the energy saving improvements (and energy generating technologies) that you would like, BHESCo can source competitive installer quotes and project manage the entire installation on your behalf, subject to an agreed project management fee.

If suitable, BHESCo can also help to finance the upfront project costs through our Pay As You Save initiative. In this way, you start to make savings immediately, with a portion of your monthly energy bill savings being used to repay the upfront cost to BHESCo over an agreed number of years.

Case Study

domestic solar panel and battery storage combo brighton hove

In 2019, BHESCo completed an energy survey for Ed’s house in Brighton.

We recommended that the property was ideal for rooftop solar PV combined with a Moixa smart battery.

BHESCo project managed the installation of the technologies, which we estimate will meet 90% of the electricity demand at the property and save Ed £10,164 over the next twenty years.

When should I get an energy survey?

A BHESCo energy survey should be considered by property owners who are interested in understanding their heat and power consumption and in making improvements to the energy performance of their building.

Examples include homeowners looking to reduce costs, business owners who want to reduce overheads, or landlords responding to changing compliance issues (such as meeting new Minimum Energy Efficiency Standards).

An energy survey should also be considered by anyone who is in the process of buying or selling a property, or who may wish to better understand their energy use without requesting a formal Energy Performance Certificate (EPC).

BHESCo is based in Brighton and Hove and our services are available to property owners throughout Sussex.

Do you offer Energy Performance Certificates (EPCs)?

An Energy Performance Certificate (EPC) is a regulatory requirement for the sale and rental of properties.

An EPC includes a straightforward assessment of the current energy efficiency level of a property, in addition to some basic suggestions of improvements that could be made, as well as associated savings.

Our experienced Energy Saving Service team are qualified to deliver domestic and non-domestic EPCs, and prices for these can be obtained upon request.

Please note, however, that BHESCo was formed to develop long-term partnerships with customers who want to take meaningful action to reduce their energy costs and carbon emissions. For this reason, whilst we can offer both domestic and non-domestic EPCs, this does not form a core part of our business offering, and any property owners who are looking for an EPC only may wish to consider alternative options.

"We know that to reach net zero we need to improve energy efficiency. To reduce people bills we need to improve energy efficiency. To transition to low carbon heat we need to improve energy efficiency. And now, even more than before, we need to step up and improve the energy performance of our buildings as our homes become our workplaces."

What measures are in place to ensure social distancing?

We have put significant time into developing processes that ensure we are protecting the health of both customers and workers, to give confidence to all that we are able to continue our good work towards a low carbon future.

In light of the Coronavirus, we have reviewed every aspect of our Health and Safety system and work processes. Our Energy Saving Team will conduct all surveys wearing full Personal Protective Equipment (PPE), will make use of hand sanitiser, and wherever possible, will complete an energy survey when a property is unoccupied.

We ask that doors to rooms and loft hatches are left open so as to minimise contact with household surfaces, and where a surveyor does make contact with any surfaces, they will clean these with antiseptic wipes before leaving the property.

How long does the energy audit process take?

Domestic surveys should take no more than 1-2 hours, but can last up to 3 hours for four to five bed properties. For non-domestic properties we will provide an estimate of the time required based upon building plans and a discussion with the property owner.

Following the on-site survey, we’ll have your energy report ready for you after fourteen working days. The report will detail all the ways you are wasting heat and energy in your property and recommend the most cost-effective ways to improve this quickly.

If you would like to discuss your options with one of our experienced Energy Saving Team then contact us on 0800 999 6671.

Once you have completed the booking form our Energy Saving Team will contact you to arrange the best time to visit.

"To decarbonise your house is an extremely difficult thing to do. You’ve really got to be committed to it. You’ve got to become your own project manager, your own thermal engineer, which is a million miles away from what people want. You want to be able to phone one person, and for them to sort it out”

How much does an energy survey cost?

The cost of a BHESCo energy survey is dependent on the size of a property.

For domestic properties we base this on the number of bedrooms. For commercial premises this is based on the size of the property in square metres.

As a not-for-profit co-operative, we have kept the cost of our energy survey as low as possible. Our prices are in-line with the industry standard, and in many cases are significantly lower. For example, an energy survey from the Royal Institution of Chartered Surveyors (RICS) costs on average £400 – £500.

A BHESCo energy survey is a unique, bespoke service, offering excellent value for money at a considerably lower cost than some of our competitors in the industry.

It is worth remembering that a BHESCo energy survey will identify any technologies which may be ineffective or inappropriate for your property. This could save you a great deal of money (not to mention time and stress) by avoiding the installation of technologies that will not deliver the impact you may have expected.

For domestic customers who decide to work with BHESCo to install your improvements we can absorb the cost of your energy survey into our project management fee.

Survey prices are listed in the table below. All prices shown are exclusive of VAT.

If a property is significantly larger than we had anticipated we reserve the right to charge for our time accordingly.
