Would like to say a huge thank you to Jimmy & Mary for their fantastic customer service! From first contact with Mary who was kind, friendly and knowledgeable and then contact with Jimmy who was able to diagnose the issue and solve the problem with pictures and communication over the telephone. Over the moon with this company. I will be using them again for sure and will be recommending them to everyone! Thank you again Jimmy & Mary, so impressed with you both! John McNulty - St.Austell

Contacted Jimmy's plumbing after the boiler engineer diagnosed a problem with our gas regulator. I was expecting a few weeks wait but the lovely lady on the phone booked me in straight away. Within an hour Jay was replacing the regulator and servicing the boiler. Lovely chap to deal with, amazing service. Would happily recommend ! Thanks so much!

Great service from Jimmy's plumbing & heating. Talked me through how to fix my boiler issue via what's app video call - saving me the cost of a call out. Really helpful, so pleased, thank you!

I had booked in with Jimmy's Plumbing for my first boiler service. Not only did they fail to turn up, but I waited in at home and they didn't let me know that they weren't able to attend. When I telephoned to query my booking, I was told that they had an emergency and would get back to me within the next couple of weeks. Reading other reviews from Google, it seems like I've not been the only one to be let down by them.

Booked a service over a month before the date. No one turned up so I rang. Woman apologised and said they had an emergency and said she'd call me back to let me know what was going on. She didn't. I rang back and rebooked another slot later that week. Didn't hear anything on the day and no one turned up.. I rang only to be apologised to again and told they had had yet more emergencies and they took priority over services. She said they were too busy to book me in again- lots of apologies but at the end of the day not fulfilling two appointment commitments. Essentially, implication was services were not worth their while. So cannot comment on quality or value for money, can only comment on their communication and care of customers which was poor.

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.
