I had a great experience with On Point Plumbing. Before contacting them, I had approached several other plumbers who tried to push me toward alternative water-treatment technologies because the space under my sink was minimal. Jac from On Point Plumbing, however, visited in person, assessed the area, and told me they could carry out the work with some careful modifications to my under-sink cabinet. This was a great result, as my main priority was getting soft water. The piping work to install the new water softener and radiator was done neatly and professionally, and Nick was very informative and helpful throughout the whole process. They even took the time to show me some of the tools I’d seen on YouTube (Milwaukee hydraulic press tool and even demonstrated it in action). Jac offered suggestions for future improvements and was honest about when extra work wasn’t needed, explaining when the cost wouldn’t be worth the payoff (super appreciated as a first time home owner). Their time estimate for the job was accurate, the work inside the tight cabinet was pristine, and the final result was beautifully done (see attached picture for the tiny space I have) and I now have soft water throughout my home. Super recommended

Excellent service. Jac responded quickly to my request. He is professional, knowledgeable, dependable and communicated clearly throughout the work process. Thank you to Jac and Nick for solving a complicated plumbing issue and installing a new boiler. I can highly recommend On Point Plumbing.

We had a boiler breakdown, called On Point plumbing on a recommendation, and they came out very quickly, and a day or two later we had a fabulous new Vaillant boiler with remote control via an app (plus wall control) bringing us into the twenty first century. They were competitive on price (I had another quote) and well presented and tidy. In short, I can't recommend them highly enough. First class.

Oh my word, this plumbing company is the best. Customer service excellent and so reliable. The work is amazing, started and completed on time and at a very competitive price. Will always be using Jac and Nick again for any plumbing needs as they are definitely five star in all aspects, and are both top people too. Thank you both

Hi Everyone, ⭐️⭐️⭐️⭐️⭐️ **Excellent Communication and Professionalism** Even though Jac hasn’t carried out the boiler installation yet, I’m already very impressed with his professionalism. His communication has been excellent—clear, prompt, and reassuring. He’s been helpful with every question I had and made the whole process feel smooth and well-organised. If the quality of his work matches the quality of his communication, I’m confident the installation will be done to a very high standard. Highly recommended so far! Look no further if you need a professional for your home. Very kind!

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.
