10 Questions to ask an Installer

Do they have Microgeneration Certification Scheme (MCS) accreditation? 

Without this you will not be able to claim your Feed in Tariff.  They should have the MCS logo clearly displayed on their paperwork. 

EOS Energy is fully MCS Accredited as well as an active member of the Renewable Energy & Technology Alliance and the Micropower Council.

Do they offer a manufacturer backed 10 year warranty on their inverters at no extra cost so that you have peace of mind?

We appreciate that things can occasionally go wrong with electrical equipment and you don’t want to have to pay for replacement equipment if it fails.  

The EOS Energy Warranty Scheme gives 10 years peace of mind, as standard, and this can be further extended to 25 years.

Do they calculate how much you are likely to receive from your PV system using actual sunlight for your locale?

Many installers only use the nationwide average sunlight level for these calculations and this may well give a false impression of what level of electricity you generate.

We use proven survey software which gives more accurate and trustworthy readings, based upon 20 years of climate data.

Do they calculate the amount of Carbon Dioxide saved using the SAP 2009 procedures?

Often installers overstate the amount of CO2 that you will save by using out dated figures taken from the 2006 Building Standards Part L2a.

Our own engineers only use the most up to date standards.

What financial standing do they have and how large are they?

Obviously, you need to know that they are going to be able to complete your installation and that they will be able to come back and maintain the system if asked to do so.

EOS Energy is part of the multi-award winning Alumet group of companies and has offices in Warwickshire, the West Midlands and West Yorkshire.

Is the equipment that they are installing MCS accredited?

If the PV panels and the inverter are not MCS accredited you will not be able to claim your Feed in Tariff.

All our products meet the current requirements and our own stringent quality assurances tests.

How long will the PV system operate at full efficiency and will it decrease over the years? 

Your installer should advise you that, on average, a PV panel looses 1% efficiency every year.  They should also take account of this reduction in the preparation of their calculations to show you what your Feed in Tariff payments will be.

Does your chosen installer have sufficient insurance cover?

Before letting an installer carry out any work on your roof, you should ask what level of public liability, professional indemnity and contractors all risks insurances they carry.  If they have an accident or cause damage to your roof, you need to make sure that their insurances will cover the repairs.

EOS Energy carries £10m of Public Liability and Professional Indemnity Insurance cover.  EOS Energy also carried £5m of Contractors All Risks Insurance.

Is the property survey free and without obligation? 

There are a number of companies requesting £100 deposits for the preparation of a survey to allow them to put a quotation together for you.

We will not charge a penny until such time as you place an order for a system with us.

Do they deal with the Planning Authority and National Grid for you?

Many installation companies leave you to deal with the paperwork required to sort out planning permissions and Feed in Tariff paperwork.

We will deal with all necessary permits and paperwork to give you a stress free installation.
