Local installers around Shipbourne & Plaxtol
As outlined on the Home Upgrade Journey page, there are several ways to approach home energy improvements. Some homeowners choose to work with a retrofit assessor or advisor to develop a detailed plan, while others prefer to research their options and manage the process themselves. There are many free online retrofit assessment tools to help you get started.
If you want to find local installers yourself, then this page is for you.
Managing your own home upgrade project can give you greater control over decisions, timelines and costs. However, it also means taking responsibility for understanding the options available, selecting appropriate measures for your home, and choosing competent installers.

We've also included a list of local installers and contractors operating in the area. These are intended as a starting point for your research rather than an endorsement, and we encourage you to carry out your own checks before proceeding with any work. you to carry out your own checks before proceeding with any work.

What to look out for when shopping for a solar PV or heat pump installer
1. MCS Accreditation (Essential)
Ensure the installer is certified under the Microgeneration Certification Scheme (MCS) for the specific technology being installed. This is a key indicator of technical competence and is required to access schemes such as the Boiler Upgrade Scheme and Smart Export Guarantee.
2. TrustMark (Preferred)
TrustMark is the UK Government-endorsed quality scheme for trades carrying out work in and around the home. It provides assurance that registered businesses meet recognised standards for technical competence, customer service and trading practices. TrustMark registration is particularly important for insulation and whole-house retrofit works and is required for many government-funded schemes.
3. RECC Membership (Preferred)
Membership of the Renewable Energy Consumer Code demonstrates a commitment to good sales practices, transparent contracts and consumer protection. It provides additional safeguards if problems arise during or after the installation.
4. NICEIC Certification (Preferred for Electrical Systems)
For solar PV, batteries and EV chargers, NICEIC certification provides assurance that electrical work will be carried out safely and in accordance with UK wiring regulations.
5. Kent County Council Trading Standards Checked (nice to have)
A local approval scheme that recognises businesses which have been vetted by Kent Trading Standards. The scheme aims to give consumers greater confidence by identifying businesses that have demonstrated a commitment to good customer service, fair trading and legal compliance.
6. Strong, Detailed Reviews
Look for reviews that describe the customer's experience in detail, including communication, design, installation quality and aftercare. Consistent positive feedback over a long period is usually more meaningful than a large number of recent reviews.
7. Local Experience with Similar Properties
Installers with experience of local housing types, planning requirements and grid constraints are often better equipped to design suitable systems. Ask for examples of nearby projects or homes similar to your own.
8. Evidence of Proper System Design
A good installer will tailor the system to your property rather than offering a one-size-fits-all solution. They should be able to explain their design process and justify key decisions such as system sizing and specification.
9. Clear Aftercare and Support
Check what happens after installation, including warranties, servicing options, monitoring and fault support. Good aftercare can be just as important as the installation itself.
