RECC Registered
Who We Are
RECC sets out high consumer protection standards for businesses who are selling or leasing renewable energy generation systems to domestic consumers. RECC is approved by the Chartered Trading Standards Institute as part of the Consumer Codes Approval Scheme and is also a TrustMark Scheme Operator.
Our Code
By displaying the RECC logo, members signal they have agreed to abide by the high standards set out in the Consumer Code, following the consumer journey from start to finish, and in the Bye-Laws. Both the Code and the Bye-Laws dovetail with the Microgeneration Certification Scheme (MCS) installer standards.
QANW Registered
A requirement of the consumer code (RECC) is to provide assurance that we are registered with QANW.
Insurance Providers
RECC requires members to protect deposits and workmanship warranties.
- RECC requires members to insure any deposits they take, together with the workmanship warranties they issue, to protect a consumer against an installer ceasing to trade.
- Deposit cover and workmanship warranties can come in the form of Insurance Backed Guarantees (IBGs) and should be provided to domestic customers by the installing contractor to ensure the correct consumer protection is in place.
- There are a number of insurance providers who offer such products and meet RECC’s minimum criteria for this type of cover.
Our Approach
If you are looking for a larger company that has clever sales techniques and relies on multiple sales and turnover, then you’re in the wrong place. Industry experience has taught us that as the number of employees grows, standards decrease due to the pressure put on sales teams and engineers to complete works.
GI Developments is a small company that offers a point of contact from the start of your enquiry to the completion of the works.
Our Director
GI Dev Director, Wayne McGuire, started out as a plumber before going on to qualify with domestic and commercial gas, solar and oil technologies in the heating industry.
Adding to this we now support the balanced approach for heat pump technology installations when and where suitable and with the understanding and needs of our customers.
Trading for years without any marketing is testament to our business, however, we realised that new customers should be given the opportunity to understand what our company competence and experience has to offer.
We support our industry’s efforts to clean up its act and improve working practices from old which is shown with our continued up skilling approach. This is why we are pleased to have undertaken 150/200hrs of training and exams recently provided by Heat Geek one of the industries key (leading for change) companies.
Our Mission
The site was created to offer our new customers confidence in what services we undertake. Upgrading to green technology can be somewhat daunting and expensive. For that reason, customers will want to see previous works and capabilities.
