I’ve now used S-Tec twice and have been thoroughly impressed on both occasions. From the outset, they’ve been a genuinely professional outfit - turning up exactly when promised and delivering work to an exceptionally high standard. They initially installed my inverter, battery and EV charger system, and more recently completed a seamless battery expansion upgrade. The service from Carly and Jacob has been outstanding throughout, while Matt handled the installation with real expertise and care. All in all, a highly reputable company that I would not hesitate to recommend.

Matt and his team installed our solar and battery system. They were incredibly professional and friendly. Matt took lots of time to explain how it all worked. Can't recommend them enough A+

I recently contacted S-TEC to arrange the DNO application for my recently installed Solar Panels. Mandy at S-TEC was incredibly professional, knowledgeable and swift with helping me. I would personally like to thank Mandy for her kind assistance.

I have been extremely impressed with Amanda Worthington. Each time I have requested information on the panels we have on our home she has dealt with all my queries most efficiently. A breath of fresh air in this day and age when the customer gets passed from one recorded message to another. Thank you Amanda. By the way she deserves a pay rise.

Frequently asked questions
How do I know you’re properly qualified and certified to install heat pumps?
We are MCS‑certified and registered with an approved consumer protection/competent person scheme, which is essential for quality assurance and to access grants like the Boiler Upgrade Scheme (BUS).
Can you tell me if a heat pump is actually suitable for my home?
We carry out a detailed home assessment, including property type, insulation levels, existing heating system and available outdoor space, to confirm whether a heat pump is a good fit.
What type and size of heat pump will you recommend for my property, and why?
We design the system using a heat‑loss calculation for your home, then match the correct kW size and model (for example, air‑source vs ground‑source) so it runs efficiently and reliably.
What will the full installation cost be, and what’s included in your quote?
Our fixed quote clearly lists the heat pump, cylinder, controls, labour, scaffolding (if needed), electrical work and any radiator or pipework upgrades, so you know exactly what you’re paying for.
Can you help me access government grants like the Boiler Upgrade Scheme?
Yes, as an MCS installer we can confirm your eligibility, apply for the BUS grant (worth up to £7,500) on your behalf and deduct it directly from your quote.
How much disruption should I expect during installation, and how long does it take?
A typical air‑source heat pump installation takes around 2–5 days, and we’ll agree locations for the indoor and outdoor units, manage any planning considerations and keep you informed each day.
Will I need to replace my radiators or upgrade anything else in my home?
After the heat‑loss survey, we’ll advise if any radiators, pipework, electrics or hot‑water cylinder need upgrading so the system can run efficiently at lower flow temperatures.
How noisy is the outdoor unit and where will it be installed?
Modern heat pumps are designed to be quiet and must meet UK noise regulations; we’ll position the unit to minimise any impact on you and your neighbours and comply with local planning rules.
What warranties, servicing and aftercare do you provide?
You’ll get manufacturer warranties on the heat pump plus our workmanship guarantee, and we offer ongoing servicing and support to keep your system performing at its best.
What running costs and savings can I realistically expect compared to my current boiler?
We’ll estimate your likely annual running costs and potential savings based on your current fuel type, insulation level and tariffs, using real‑world performance data rather than lab figures.
