I can’t recommend this engineer highly enough. After our boiler suddenly failed, we were left in a panic with no heating in the middle of a cold spell. A friend suggested contacting him, and it turned out to be the best advice we could have received. If you’re looking for boiler repair in Hertfordshire, he is absolutely the person you want. He responded quickly, arranged a visit the same day, and delivered exactly the kind of fast boiler repair we desperately needed. He arrived on time, was friendly and polite, and immediately put us at ease. Andrew clearly knows boilers inside out and had the problem fixed far quicker than we expected. For anyone in Hemel Hempstead needing a boiler repair, it’s rare to find someone so reliable, honest, and efficient. He even gave us helpful tips on maintaining the system to avoid future issues. The quality of the repair was excellent, the price was fair, and the overall service was outstanding. It’s refreshing to meet a tradesperson who genuinely cares about doing a great job and supporting local customers. We’ll definitely be calling Andrew again.

We moved on new property during the Christmas time , and since then, we had ongoing issues with our boiler and underfloor heating. We had several engineers come out, but none of them managed to fix the problem properly — any improvement only lasted a short time. A friend then recommended Plumb Heating, and I’m really glad they did. Andrew and his teammate spent three days working on the system, carried out a full power flush, and discovered that one of the heating pipe had a solid blockage. It turned out the system hadn’t been properly maintained by the previous owner. Some of the pipes were replaced, and since then the system has been working perfectly. The house heats up much faster, and everything runs as it should. I highly recommend Plumb Heating to anyone in Hemel Hempstead looking for a reliable boiler or underfloor heating engineer. Excellent work and very professional service. Thank you!

I recently used Plumb Heating Ltd in Hemel Hempstead and they did a great job to our house. They moved the boiler from top floor to ground floor, replacing all pipework, replacing all radiators. Installing new water softener makes the difference to our house. I don't have words to thank them after they installed wet underfloor heating on our new extension .Now the kids love playing on the floor during cold days. Their punctuality and professionalism made me write this review and strongly recommend Plumb Heating Ltd to all my friends.

Very pleased with Plumb Heating in St Albans for the boiler and hot water installation, including gas work and radiators. From the initial planning through to execution, everything was handled professionally and efficiently. Very accurate with every detail and completed within the agreed timeframe. Highly recommended.

We recently moved to St Albans and Plumb Heating was recommended by our neighbours. We had a leaking rusty radiator, and Andrew came out quickly to identify the problem. He explained that the system was full of sludge and several radiators were badly corroded. In the end, we replaced all the radiators and had a power flush done. The work was carried out efficiently and to a high standard. Andrew was knowledgeable, professional, and very easy to deal with. We’re planning to replace the boiler in the near future, and we’ll definitely be calling Andrew again. Highly recommended!

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.
