Spoke to Arwel This morning to discuss a problem with my boiler. ( F75 Code ) On A property that I’ve just purchased with no history on the boiler. Even though I’ve never met Arwel or ever used The company before His advice was too contact Vaillant before calling anybody out and check it’s not under warranty. I have now checked and can confirm The boiler is under warranty Until March 2026, So I have booked in a repair and service all included in my warranty so a big thank you to Arwel. 👏

I can't recommend Arwel and his team enough. Saved us before and the work is always top quality. Always get back to you with honest advice and help. Fitted a new water pump no troubles at all. will use their service again with anything we need. 5 star

Jackie Turner
Excellent company, professional, very knowledgeable and great service. We had a new air to water heat pump installed with them, everything went to plan and it works brilliantly. All questions answered very thoroughly. I would definitely recommend this company.
Michael Scott
One of the best experiences I've had with a tradesman. Gets back to you straight away, communicates in detail and promptly, and most importantly gets the work done by a schedule that far exceeded our expectations. Andy and the apprentice who saved our leaky shower by fitting a new one were brilliant, too. Would definitely use them again. Diolch yn fawr.

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.
