Just had my leaky loo fixed through the Northumbrian Water scheme. Excellent service by a guy from Gateshead. Job well done, no problems. 5☆ service.

I got my leaky toilet fixed through Northumbria Water. The plumber was very friendly and polite and in no time the problem was fixed. Very happy customer. Thank you.

We inherited JN Dunn as our remedial installer after purchasing a new build property from Ascent Homes. We expected there to be snags as with any new build home, however 8 months later, and we still have intermittent hot water issues, and today have experienced our third no-showing of an appointment by JN Dunn. The overall aftercare service we have been provided with has been abhorrent, with countless of both technical and customer service mistakes, all of which had a negative impact on us. As JN Dunn has now been removed from their duties working on Ascent Homes properties, I can only presume that we aren’t the only ones who have experienced such issues. Ascent Homes have now been forced to find us an alternative installer for remedial aftercare due to the poor standard of service we have received.

Phoned on the day to cancel my appointment even though the appointment had been booked in the previous week. Broken part fitted which now works worse than before! Cannot get a new appointment for a week! (If they turn up) Phoned asking to speak to a manager but never available, I have asked for a manager to call me back but nothing!!! AVOID!!!

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.
