What is Renewable Energy?

Renewable energy is made from resources that nature will replace, like wind, water and sunshine. Renewable energy is also called "clean energy" or "green power" because it doesn't pollute the air or the water

What is an Energy Performance Certificate (EPC)?

Much like the multi-coloured sticker on new appliances, EPCs tell you how energy efficient a building is and give it a rating from A (very efficient) to G (inefficient). 


We can provide your property with a new EPC when we perform a survey.


An EPC shows how costly it will be to heat and light the building, and what its carbon dioxide emissions are likely to be. The EPC will also demonstrate what energy-efficiency rating could be achieved if improvements are made, and highlights cost-effective ways to achieve a better rating. 


We use the Heat Demand figure from your EPC to establish how much Government subsidy you will be eligible for. 


EPCs are valid for 10 years from when issued.

Tell me about Government Subsidies and the Renewable Heat Incentive

The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help the UK reduce its carbon emissions and meet its renewable energy targets.


People who join the scheme and stick to its rules receive quarterly payments for seven years for the amount of clean, green renewable heat it’s estimated their system produces. Since opening in April 2014, the scheme has already seen thousands of people successfully join and receive payments. 


Home owners are eligible to recieve Government Subsidy, which is called the Renewable Heat Incentive. The amount of funding is calculated using the Heat Demand estimate from your EPC. 

What is the price of a new system?

It depends entirely on the size of your property and your plumbing / hot water cylinder requirements. It also depends on the complexity of the control system that you want, (for example an app with multiple zones that can integrate into Hive / Nest / Apple Home / Alexa)


With Ground Source Heat Pumps, another important factor is how we collect heat from the ground, normally either via trenches or vertical bore holes. This can make up a significant part of the installation price.


For Air Source Heat Pumps factors such as location of water cylinders and any replacement of radiators will affect the price.


We always work towards ensuring that systems are at least 95% funded by Government Subsidy and in nearly ALL cases, Government funding combined with the saving on running costs shows a significant, positive financial return.

How much does it cost to run?

According to The Energy Saving Trust it is safe to assume that Heat Pumps will generate significant savings on your fuel bills, especially if you are replacing Oil, LPG or Conventional electric heating. We aim to deliver savings of up to 50% on current running costs.

Do you offer finance?

We have partnered with a leading Renewables Finance Broker that can offer extremely competitive asset finance to help ease capital expense. We aim to mirror RHI payments with a suitable finance product, please note that all finance is subject to status.

What is an Air Source Heat Pump?

An ASHP (Air Source Heat Pump) is a renewable heat source that provides heating and hot water for your property and replaces a traditional boiler. It uses some electricity to ensure that your demand for heat is always catered for. It runs much more efficiently than a traditional boiler and is capable of working in temperatures as low as -15 C. 


The unit looks like an air-conditioning box on the side of your house and works just like a refridgerator in reverse. It sucks in air from outside and uses a heat exchanger to provide heat and hot water. It works in conjunction with a specially designed hot water cylinder.

What is a Ground Source Heat Pump?

A GSHP (Ground Source Heat Pump) is a renewable heat source that provides heating and hot water for your property and replaces a traditional boiler. It uses some electricity to ensure that your demand for heat is always catered for. It runs much more efficiently than a traditional boiler and is capable of working in low outside temperatures.


Heat from the ground is absorbed at low temperatures into a fluid inside a loop of pipe (a ground loop) buried underground. The fluid then passes through a compressor that raises it to a higher temperature, which can then heat water for the heating and hot water circuits of the house.

How long do they last?

Manufacturer's recommend that average lifespan for a Heat Pump is 20 years

What maintenance is required?

Very little maintenance is required for Heat Pumps. We recommend an annual service by a qualified Cotswold Energy Group engineer to ensure that the unit is working as it should - this could also be required in on order to claim RHI payments from the government.

How much space do I need?

Space requirement depends entirely on the amount of heat demand in your property and the type of technology required. For example, an ASHP might need a very small footprint on the side of a property (like an air-conditioning box) but a GSHP will need either trenches or vertical bore holes to house the ground loops. For a large 5 bedroom house, this could be 6 x 100m trenches or the equivalent in bore holes.

Do they work if it's cold outside?

Short answer is yes. Heat Pumps are one of the dominant form of domestic heating sources in Scandinavia and are designed to work in extreme UK temperatures. The efficiency is decreased slightly when it is colder outside because the unit has to work harder to create more heat. Rest assured that these variables are factored into the calculations that we provide as part of your bespoke quote.

How do I control my heating and hot water?

One of the major benefits of our renewable heating technology is that it can integrate into the majority of popular heating control systems. This provides the ability to control your heating and hot water through smart phone apps, web browsers or just traditional wall mounted systems. We offer bespoke control systems designed to suit your needs and your appetite for smart technology.

Am I really helping the environment by getting a Heat Pump?

Yes, absolutely. Every tonne of carbon saved makes a positive difference to climate change and using renewable heat sources is a significant contribution to saving carbon. We can estimate exact carbon savings when we create your bespoke design - please ask your consultant for more information.

How long does it take to install?

This is governed entirely by the complexity of your heating requirements. An ASHP should take no longer than a week, in many cases it can be done within 3 days. 


GSHP projects may take a little longer but we always provide a detailed project plan outlining key milestones and project dependencies. 

Will it work with my existing plumbing?

Yes, your pipework is likely to be compatible (save for likely replacement for your main flow and return between the hot water cylinder and the heat pump). You may also need to replace / upgrade radiators to ensure that the property conforms to british heating standards. We will provide a detailed recommendation and price to do this as part of any works.

What kind of warranties are there?

This is governed by the type of system that is most suitable for your house. Different manufacturers offer differ warranty packages and nearly all can be upgraded to a 7 year warranty to ensure that your system is covered by the manufacturer for the duration of your RHI payments. Our plumbing and labour workmanship warranty is two years as standard.

What insurance do Cotswold Energy Group have in case something goes wrong?

Rest assured that Cotswold Energy Group are covered in the event of any unforeseen issue. We have Public Liability Cover, Employee Liability Cover and Professional Indemnity Insurance. 

Who do i complain to if something goes wrong?
