Frequently Asked Questions


1. What is the RHI?

The RHI is the governments Renewable Heat Incentive. The RHI is designed to provide financial support to anyone wanting to install green energy for their home or business. The RHI works by paying the owner of the heating system quarterly payments for the amount of energy they have produced. The payments are measured using either predictive or metering methods. The NON-DOMESTIC RHI is currently already in action and the DOMESTIC RHI launches in spring 2014.

2. What is the FIT tariff scheme?

FIT stands for Feed in tariff and is the governments payment scheme for energy produced by electrical green energy. Wind turbines and Solar PV are the main eligible sources for the FIT scheme. It works by measuring production from your renewable energy and paying quarterly payments back to the householder relating to your system.

3. What is the premium payment scheme?

The premium payment scheme is the current type of grant available for installing renewable heating technology in your homes. However, this grant offers a small financial incentive compared to a typical installation cost. Greenio is advising that consumers install there renewable technology as soon as the Domestic RHI launches in spring 2014. This will guarantee that you will claim the initial RHI tariffs which will often be the best rate you will ever receive.

4. What do I do if I have claimed the premium payment already?

If you already have renewable energy installed and you have claimed your premium payment don’t worry! As soon as the domestic RHI launches you will be able to apply to receive these new payments but you will be classed as a Legacy applicant.

8. Will I need planning permission?

Nearly all green energies apart from wind turbines do not normally require planning permission except for areas of natural beauty or a planned installation on a listed building.

9. My installer/finance company hasn’t contacted me?

If you haven’t received a phone call or email from one of our registered installers or finance companies then please don’t worry. Please allow up to 5 working days from registering your interest on the site for an installer/finance company to contact you. If you have not heard anything after this timescale please contact the office on Freephone 0800 201 4503 or email us at and we will chase the enquiry up for you.

10. I forgot to reply to the text message or email you sent me to confirm I wanted someone to contact?

Don’t worry if you forgot to reply, one of our installers will still contact you but it may take slightly longer than usual.

11. I would like a heat pump but the cost calculator recommends a biomass boiler?

Our cost calculator is designed to provide the most beneficial information to the general public. If the cost calculator thinks your house is less insulated than a new build home it will recommend a biomass boiler. This is due to scenarios where installers have installed standard heat pumps in less insulated buildings and electrical usage has been very high therefore increasing fuel costs. However, there are heat pumps available on the market designed for high temperature outputs so please contact the office on 0800 201 4503 or email us at for a cost calculator relating to this.

12. What happens if I have a problem with my installer or my installation?

We hope you wont ever have an issue with any installer or installation but if you do please follow this procedure.

Contact your installer and give them a set time period in which they must respond and agree to amend any problems. If you are not satisfied or the installation company have not responded you will need to submit a formal complaint in accordance with the MCS complaints procedure, which is available here.

13. What do I do if I’m not happy with the installers you have sent me?

We would like to think that all our installers act in a professional and likeable manner but if you are not happy with the ones that have given quotes then please contact us on 0800 201 4503 or email us at Please note Greenio will not supply new installers based on complaints regarding their quoted costs.

14. What do I do if I have a special enquiry?

If you have a special enquiry such as a large commercial or domestic installation or you are thinking about using renewable heating for a swimming pool please contact us direct on 0800 201 4503 or email us at Greenio’s consultancy division can put everything in place to carry out your project from start to finish.
