Had MJS do plumbing work at our property as part of a renovation project as were recommended by another contractor. While new pipework etc was done and routed well they turned up each morning around 9 left for an hour "to get parts" then left each day before 4pm ( 30 mins for lunch) bills appeared to be from 9 -4 at least (and its not a cheap hourly rate). After install of new water pump from well they returned 3 times to identify a leak as warning light was on - each time it was "caused by other issues around our well and return valves etc" all of which was chargeable - for some months afterward we tried to get them back as light still came on hourly after resetting. Eventually almost 12 months later we had water coming up through a toilet floor they never responded so we contacted the building contractor who got them out they then went looking for the leak even though we told them where it was. £350 later they had ripped up floor and fixed the leaking joint which we suspect had been get worse since day one. We never have had any pressure from an upstairs tap in one room but they were just not interested. Lets not forget the hot water flushing a loo which had to be sorted - lucky could still access pipes after the tiling had been done. They also fitted a new air source heat pump cost of £15k when quoted we were told would get £8k back via grant over 7 years. After we had paid and put in for grant turned out to be under £6k. They never have returned emails or calls regarding solar options so going elsewhere and glad we are as the aftercare service was abysmal even took two months to arrange a service on the heat pump and then it was outsourced. It appears they only respond when a main contractor contacts them or until they have the money.

A great Company. Very professional and friendly. Went the extra mile to help us in rectifying problems caused by another company, at some inconvenience to themselves. They came when they said they were coming and did what they said they’d do. Very friendly and helpful throughout, explaining how to operate/ set our Air Source heat pump whenever we had an issue. I would certainly use them again.

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.
