Paul Stenning
Harlech completed a full installation with solar panels, air source heat pumps and battery storage. All was completed quickly and efficiently. There were a few minor snags that came to light after the installation, but with a lot of work and retrofitting in combination with some older heating elements that was probably to be expected. In all I would say a good service and a genuine four stars for the work, communications and aftercare.
A Walk
Harlech electrical services have recently completed installing an air flow heat system and solar panels to my property. I have two words to describe the entire process and that is Utterly Amazing. The guys who fitted the system were efficient, professional and very polite. Jemma and Paul who arranged the work were always at hand to deal with any concerns which they did immediately. I can only thank you all from the bottom of my heart. You’ve made my home warm and cost effective. Thank You 😁👍🙏

Complete shambles and lots of damage to our property and don't reply to emails They promised us they would repair all damage made by the workers but stopped all contact with us. Workmanship appalling.

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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
