YEARS OF EXPERIENCE
COUNTRY HOUSE
This impressive early 20th-century property has been in the same family for three generations. During WWII, it was used as an officers' mess and later restored as a family home. However, major updates weren’t undertaken until the current owners decided to modernise the property for 21st-century living. This included extensive renovations and a complete overhaul of the plumbing and heating systems.
The house previously relied on a gravity-fed cold water system from a spring, with outdated lead pipes, poor water pressure, and frequent issues such as frozen toilets and long waits for hot water. J P Westall Ltd was tasked with replacing all pipework, upgrading water pressure and storage, refurbishing or replacing radiators, installing underfloor heating in a new kitchen extension, refitting all bathrooms and ensuites, and adding an air-to-air heat pump for the wine cellar.
Westalls, recommended by the family’s architect and previously used for estate cottages, were trusted to deliver reliable, high-quality work. The family was delighted with the results, noting that the project finished “on time and under budget,” with no financial surprises. They praised the materials, workmanship, and professionalism, and were especially pleased with the modern comforts now enjoyed—no frozen toilets, better heating, and instant hot water.
Post-installation support was excellent, including prompt resolution of an airlock and a detailed valve chart. The family appreciated the friendly, consistent team, and their ability to trust the work without close supervision. They now wholeheartedly recommend JP Westall for quality, reliability, and outstanding service.
NORTH BARN, HEXHAM
Forty years ago, we converted a centuries-old farm building—part cattle shed, part stable—into our home. In 2009, we replaced our oil boiler with green technology, installing an Air Source Heat Pump (ASHP) along with PV and Solar Thermal Panels, creating an efficient heating and hot water system.
In early 2024, we experienced a minor issue with the solar panel pump station, which JP Westall promptly repaired. Later that year, a recurring problem with the ASHP control panel led us to consider a full system replacement. After reviewing several local and national providers, we chose JP Westall for their professionalism, deep knowledge of green technologies, and strong commitment to training and employing local people.
They designed and installed a new Mitsubishi Ecodan ASHP and control panel, integrating everything seamlessly with our existing setup. The installation was completed ahead of schedule and has so far outperformed our original 15-year-old system. We were pleasantly surprised by the improved heating—thanks to up-sized pipework and the new ASHP, our radiators are now hotter and the house is noticeably warmer.
As the system has been in place for less than a year, we’ve had no need for aftercare yet, but we’ll turn to JP Westall for any future servicing or repairs.
In conclusion, we’ve been thoroughly impressed with everyone we've encountered at JP Westall. So much so, we're now in discussions with them about adding more PV panels and battery storage. We would wholeheartedly recommend them to anyone considering similar upgrades.

MOWDEN HALL SCHOOL
Mowden Hall is a prestigious private school in the Tyne Valley near Corbridge, educating children from nursery to Year 8. Originally a stately home, the site became the school’s permanent location in 1945 after evacuation from Darlington during WWII. Of its 170 students, 85 are boarders.
J P Westall Ltd has maintained the school’s heating system for over 20 years. In 2017, the Trust overseeing the school chose Westalls to replace the aging 50-year-old boiler to ensure reliable heating and improve hot water availability. Westalls designed and installed the entire system, including two modern Viessmann boilers, zoning the heating distribution, and implementing a new control system for improved efficiency.
School caretaker Simon praised Westalls’ reliability, noting that any previous attempts to use other firms had resulted in issues. The only major challenge was moving the large new boilers into the old building’s steep, confined spaces. The Westalls team devised a custom ramp system and completed the delivery without any damage.
The new system brought immediate benefits. Hot water capacity—previously a daily problem with 80+ boarders—has greatly improved, and maintenance demands have dropped significantly. Simon is especially pleased with the 27% reduction in oil consumption, warmer indoor temperatures, and the tidy, modern plant room.
He describes the project as smooth, professional, and highly effective. Simon continues to recommend Westalls to others, both domestically and commercially, and says he would choose them again without hesitation. Another successful project—and another very satisfied client—for the Westalls team.
MUCKLE BREWING
The Brief: Design and InstallaƟon of a Solar Photovoltaic System with immersion diverter, system design comprised of 10 solar modules giving a peak capacity of 4.10kWp and using immersion diversion for domestic hot water generation from surplus energy.
The feedback: JP Westall designed and installed our Solar PV system to help reduce our energy consumpƟon during the brewing and chilling process. Since the installaƟon took place at the end of May 2023, we have had our energy bill reduce by a third of normal costs. Everything that the JP Westall team said they would do has been completed in a very timely manner and got us up and running producing electricity within two days.
They were professional and courteous the whole Ɵme on site with no mess at any stage of the installaƟon. Our Muckle Brewing business continues to produce top quality ale but now using free energy from the sun and helping us to run a sustainable and energy efficient business going forward. Nicola and Tom
"Arrived on time, got stuck straight into the job. Left without leaving a trace they’d been here, except for the absence on leaks. Steve was extremely professional and pleasant. Highly recommended. We are repeat customers.
