the company has been efficient and…

the company has been efficient and helpful in the whole process from planning to commissioning of our ASHP. They have been transparent about costs, professional about installation, friendly, as careful about our house as they could be - including care for our cat - and knowledgeable about their work. They have been very helpful with regard to queries, and quick email and telephone advice.

Excellent Quality Company

As always excellent Service. I’ve dealt with Marshalls for some years now on two properties involving installation and service of Heat Pumps and Solars, they are an excellent company.
Gary (2 sugars), the heating engineer who has installed and serviced our systems is first class, as are all the engineers, electricians etc that have attended.

Service itself was good but there were issues.

Service itself was done to a good standard by a pleasant and professional engineer.
However overall communication was poor. Service was booked for 12.00 and heating was switched off from 9.00am to let everything cool down. It was a very cold, wet and snowy day. By 12.30 no one had come so I rang MCHP to query whether he was coming. They said he'd been delayed and would be there around 2.00pm. By 2.30 pm no engineer. So my wife rang MCHP again. They said he was now in Norton and would be another 40 minutes. Sure enough he arrived at 3.15 pm and the service completed. Our main gripe was that the company should have been notifying customers of the delay rather than them having to contact MCHP for updates. Especially with the cost of their service having risen 20% in 12 months. I could have saved a lot of money by having the service done by somone else.

Dear Nicholas,

Thank you for taking the time to leave us this feedback. We are pleased to hear that the service itself was completed to a good standard by our engineer, who you found to be pleasant and professional. That positive feedback is very important to us.

We are, however, deeply sorry for the significant issues you experienced with the communication regarding the engineer's delay. You are absolutely right that on a day with such severe weather—including the bad snow and ice you experienced—we should have been proactive in contacting you with updates, rather than waiting for you to call us.

We understand how frustrating it must have been to have your heating off for so many hours on such a cold, wet, and snowy day. Please accept our sincerest apologies for the inconvenience and discomfort this caused you and your wife. We are reviewing our internal procedures to ensure that communication with customers takes priority during unexpected disruptions like this.

Addressing Your Other Points

Service Cost: We understand your concern regarding the price. While we appreciate that the increase of approximately 20% feels significant, we want to assure you that this was our first price adjustment in five years. We strive to keep our services competitive and offer excellent value, and our new prices remain extremely competitive compared to the industry standard in the local area.

Customer Loyalty: We truly value your business and hate to think we have let you down. We would love the opportunity to regain your trust.

If you would like to discuss this further, please feel free to contact our office directly at 01642 913200.

Thank you again for your honest review. We hope to have the chance to provide you with a 5-star experience in the future, where our service and our communication both meet the high standards you deserve.

Kind regards,

The Team at Marshalls

Tip Top Service

Thank you for the quality of your recent installation at my property. One word, faultless.
Your guys arrived nice and early and were well prepared.
The utilities were re-routed quickly and without any hic-ups.
The Powerwall installation team were very much on the ball from the outset. The Team Leader was very well mannered and provided me with an ongoing update of what was being do, why it was being done and how long it would take but always asking if what he had proposed was acceptable.

All in all a smashing bunch of lads who deserve credit. Please pass on my warmest regards to the guys.

Great service. You will be getting a call next year for some additional work. Thank you.

First ASHP service

Good company to deal with.
Good value for money.
Prompt & comprehensive paperwork trail, following visit.
Awarded only four stars, due to having to contact the engineer after they left, to sort out a small issue; otherwise, would have been a five.

High quality heat pump install.

We have had our heatpump for 6 months and it has got us through 1 winter. The system worked much better than our old gas boiler and saved us money at the same time. The system gets better than the promised design COP (efficiency) and is easy to use.

The install process was painless, all of the govt grant details were sorted for us. The survey was very smooth and they listened to us about component placement, the locations we wanted weren't the easiest but they were the only installer willing to put equipment where we wanted it to minimise space use. We had every radiator replaced and the quality of the install was great all additional pipework and cabling was hidden in the floor void so the install looks like it was original to the house not a retrofit. Some of the radiator sizings were increased at no cost just so we didn't need to re-wallpaper rooms (radiators matched dimensions of original radiators), we didn't need to redecorate anything once the install was complete. Installers cleaned up thoroughly after themselves and left the house clean and safe after every day of work.

Installer came back a couple times to tweak the install and replace a faulty pump, this was done quickly and without bother or cost.

Pricing was competitive with other quotes and the quality of the survey process was better than other installers and the overall system design was superior and didn't cut any corners. We had a project manager as point of contact for the install process and the staff used were skilled and polite causing minimal disruption.

Dear Chris,

Thank you so much for taking the time to leave such a detailed and glowing 5-star review. We are absolutely thrilled to hear how pleased you are with your new heat pump system and the entire installation process.

It's fantastic to know that your heat pump exceeded expectations, performing even better than the design COP and providing significant savings over your old gas boiler, especially through the winter. We pride ourselves on delivering highly efficient solutions, and your feedback truly validates our efforts.

We're also delighted that the installation was "painless" and that our team could accommodate your specific requests regarding component placement, ensuring minimal disruption to your home's aesthetic. Our goal is always to provide a seamless retrofit that looks like an original part of the house, and your comments about the hidden pipework and cabling, as well as the thoughtful radiator sizing, show we achieved just that. We also appreciate you highlighting our team's tidiness and professionalism throughout the project.

Furthermore, we're glad to hear that our post-installation support, including the quick resolution of the faulty pump, was handled to your satisfaction. Ensuring your system runs perfectly long after the initial install is a key part of our commitment.

Thank you for recognising our competitive pricing, superior survey process, and the dedication of our project managers and skilled staff. Your positive experience, from the initial quote to the ongoing performance of your system, means a great deal to us.

We truly appreciate your business and this wonderful feedback. Enjoy the continued comfort and savings with your heat pump!

Best regards,

The Marshall Clean Heat and Power Team!

Great service

Great service, very responsive. ASHP review requested and booked in for the following day. Friendly and knowledagble heating engineer.
The Air Source Heat Pump was installed by Marshall and McCort in 2020. Has run perfectly since. Warmer house and lower bills.
