Why Regular Heat Pump Servicing Matters

It is easy to overlook your heat pump when it appears to be working fine, but that is exactly when regular servicing pays off. An annual heat pump service catches small issues before they develop into costly faults, improves efficiency, and keeps your running costs in check.

Consistent air source heat pump maintenance also extends the working life of your system significantly. Beyond performance, there are important safety and compliance considerations, particularly for landlords and commercial operators. Staying on top of heat pump fault finding and routine checks also helps protect your manufacturer warranty, which may be invalidated if servicing is neglected.

Dorian and his team and office staff have been excellent. While others who quoted for the work fail to show up or didn’t understand the requirement, or simply incorrectly specified solutions, SESC came up with a bespoke design that exceeded my expectations at a fair price. Always a pleasure to deal with. They have a great range of skills. I would highly recommend them. Great heat pump install, cylinder, UFH install and refit of existing solar thermal, and all in a super tight space.

Thank you Dorian and the team for a great Vaillant heat pump and new central heating installation. The installation took about 2.5 weeks to have everything wrapped up, as there was a slight delay in the stock of the specific radiators we wanted, but the team worked very hard indeed to successfully take on some of the challenges of the install. They were extremely tidy (the house has never been so clean!) and conscientious with their work. Dorian is a real stickler for the small details, guiding us through the install and checking exactly how we wanted everything. Since then, the system has been running really well. Very efficient, pushing over 400% for heating and hot water since the installation in September 2025, and performing very well during cold snaps. House stays a nice consistent temperature without costing a lot on our electricity bill. Having previously had electric and night storage heaters, the new system is a massive improvement. Where there have been a couple of snags, Dorian has been more than happy to check, fix, and advise in a very prompt manner. Overall, definitely recommend when considering a heat pump installation.

I am happy to recommend SESC solutions to anyone considering a solar energy system. I have been very impressed by the fantastic customer service and advice that SESC provided throughout our large domestic solar panel and battery storage installation project. The team were available day and evening to answer my many questions, and updated the quotation several times to fit our specific requirements. The SESC quotation included everything right from the start, such as scaffolding and bird guards, that were usually left out of other companies quotes, and a pre-installation assessment checked everything was in order. The installation day was even sooner than expected and the roofer and electricians were very professional and helpful, with everything arriving on site smoothly and all rubbish taken away. Following the installation, we have quickly received all the documentation to help us switch supplier and take up the SEG for exporting our excess electricity. I have every confidence that the SESC team will continue to be there on the end of the phone if I need any further advice or support in the future.

I could not recommend Steve and his team at SESC Solutions more highly and wouldn't hesitate to work with them again for future projects. SESC Solutions have helped us for both London and country projects. The work has always been completed to a high standard and the work has always been well managed with clear communication throughout. We look forward to working with SESC again soon.
