George installed a new boiler system for us but a few months later we developed a leak on the cylinder. As George was unable to attend we got a different plumber out to have a look. He was shocked to see that the heat expansion tank (installed by George) had been piped in completely the wrong place, what he advised was a very basic error and the likely cause of the leak. We asked George to come and give us is assessment, but on 2 occasions he failed to show up at the agreed time, with no communication. He then started ignoring my messages/ calls and in subsequent emails became defensive, telling us it was not his responsibility. We ultimately had to pay another plumber to come and rectify George’s mistakes and are pursuing legal action to try and reclaim some of the costs. I’m sure George can handle basic plumbing tasks but I wouldn’t trust him with anything important.

George did a great job, was reasonable, and was available quickly.

George is aan excellent plumber, professional and polite. Could not fault his workmanship, clean, conscientious no time wasting. Gave me a quote and stuck with it. Would recommend him without hesitation.

George and his colleagues have installed a water heater and put in new pipes for me when a gas leak was detected. They are conscientious about the high standard of the work they carry out and safety issues. Also, they are careful to clean up afterwards. Highly recommended.

The technician solved our boiler problem. However, the company charges 640£ in total for fixing the boiler within 30 minutes (just replacing a small pressure valve solved it). The 640£ charge includes two 69£ call-out (with the first call-out did nothing and second call-out is the technician), 298£ for technician working an hour, 49£ for a small valve replacement, plus 10% administration fee (what the hell is that?) and 20% VAT, which ends up as (2 * 69 + 298 + 49) * 110% * 120% = 640£. The company did not explain clearly these charges before fixing and refused to explain clearly these charges after fixing. The company insist the customer paying 640£ without explanation and give no respect to the customer with completely ignorant attitude. The technician only works half an hour which is 149£, but the company insists the technician works 1 hour because they start to count from the technician leaves the company which means even the traffic time spent is counted into the time. The company is making use of all ways to bring extra charge to the customer. So please pay attention, sincerely.

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.
