A heat pump is a big investment. The installation needs to be done right. The best heat pump installation in South London comes from an expert who understands your home, offers clear pricing, and has the right accreditations. But how do you find the right installer? Here’s what to check before you book.
1. Choose an MCS-Certified Installer
To qualify for government schemes like the Boiler Upgrade Scheme (BUS), your heat pump installer must be MCS-certified. This accreditation guarantees that the installer follows UK standards and installs energy-efficient systems.
Why is this important? Without this certification, your installation won’t be eligible for financial incentives, and you may face challenges with the system’s performance or warranty.
Tip: Always check MCS certification before agreeing to any work.
2. Check Reviews from Local Homeowners
A good installer has a reputation to match. Local reviews on platforms like Google, Checkatrade, and Trustpilot are great indicators of quality service. Focus on feedback from homeowners in South London who’ve had similar installations.
Why it matters: Reviews show the installer’s reliability, quality of work, and customer satisfaction, especially in the local area.
Tip: Look for recent reviews. A company’s service can change over time, so don’t rely on old feedback.
3. Get a Full Home Assessment—Not Just a Quote
Don’t settle for just a quote over the phone or online. The best installers will always start with a home assessment.
They’ll consider:
- Insulation levels
- Radiator sizes
- Hot water demands
- Pipework condition
Why is this important? A proper assessment ensures the right heat pump is chosen based on your home’s specific needs. Without it, the installer is just guessing.
Tip: Get at least three detailed quotes and compare them.
Look for Customised Solutions
Heat pumps aren’t a one-size-fits-all solution. A trusted installer will assess your home and offer tailored options. Avoid companies that push the same system for every property.
Why it matters: A customised solution ensures your heat pump works at peak efficiency, saving you money in the long run.
Tip: If an installer can’t explain why a specific model fits your home, it’s a sign to look elsewhere.
5. Hire a Local South London Specialist
A local installer will be familiar with the unique challenges of South London homes—whether it’s older properties, planning restrictions, or typical heating needs in the area.
Why is this important? Local installers can provide faster service, better aftercare, and understand the common issues homeowners face in your neighbourhood.
Tip: A local installer will likely have stronger relationships with local suppliers, ensuring quality materials and quicker access to parts.
6. Check Warranties and Aftercare
Heat pumps last 20+ years, but only if they’re properly maintained. Ask about the warranty and aftercare services. Some installers offer 5-year guarantees or include annual servicing.
Why this matters: Maintenance is key to ensuring your heat pump operates efficiently over its lifetime. Make sure the warranty covers both parts and labour, and clarify if regular servicing is included.
Tip: Confirm if servicing is included or if it’s an additional cost.
