Highly recommend Michael from MAK plumbing. We had another engineer out the day before who could not locate our gas leak, leaving us very worried. Michael arrived, was incredibly thorough and professional, and quickly found the source of the leak and repaired it. He genuinely made our home safe again. 5-star service for going the extra mile.
We hired MAK Plumbing and Heating company to replace our old combi boiler and number of radiators. The job was done professionally and with attention to details. Michal, not many tradesman like you these days. Thanks again and see you next year on the annual service inspection.
I highly recommend MAK Plumbing and Heating for their exceptional professionalism, reliability, and outstanding customer service. They've attended to several issues in my flat and consistently resolved everything promptly and to a high standard. Michal is very conscientious and hardworking. He takes real pride in his work and always goes above and beyond to ensure everything is done perfectly.
Michal arrived at my upstairs neighbour's leak in just fifteen minutes - charged well under going rate for emergency call out (during the heatwave after 5.30pm) and fixed the problem immediately on site. He is friendly, approachable and the only plumber I'll use! I stumbled across him for a last minute boiler check previously and always my go-to
Great service, prompt and resolved issue quickly, highly recommend
We have used this company on multiple occasions. Everything was executed flawlessly and always delivered on schedule. Excellent customer service. Thank you
Very professional service both for heating and plumbing. Punctual, honest and reliable. Very thorough work and job reports. Attended to several properties over the last past year.
I am so grateful to Michal for fixing a plumbing problem. He answered my call and within 2 hours he had attended the property, resolved the issues and provided a full report. I am so pleased to have found a reliable plumber in Streatham.
Michal recently decommissioned my old boiler and installed a new one, and he did a fantastic job. He was punctual, professional, and clearly very skilled. The whole process was smooth, tidy, and well-explained, and the new system works perfectly. It's rare to find someone so reliable and thorough. I'd happily recommend Michal to anyone needing plumbing or heating work.
Michal helped me out at short notice when my old boiler failed, replacing it promptly and saving me several sleepless nights. He always turned up at the agreed time, kept me fully informed as to what was going on and what my options were, and tidied up afterwards. I will definitely be turning to him in future, and am happy to recommend him to anyone.
We had an exceptional experience with Michal recently. He went to great lengths to repair our boiler rather than taking the easy option of fitting a new one. Michal is always punctual and sticks to his arranged schedule. We highly recommend his services.
Michal came round to fix my leaky radiator, leaky kitchen overflow pipe & noisy radiator. He identified the fault & fixed the issues quickly. He is very thorough, reliable & knowledgeable. Would 100% recommend!
Amazing to find an honest plumber with fantastic service. Cannot recommend highly enough
I always use Michal for my heating and plumbing needs. Having known him for a long time, I can confirm his work is consistently exceptional. He recently completed a demanding job replacing three old, not working radiators, and his expertise with boiler repair has saved us time and money in the past. He is trustworthy, highly skilled, and reliable. I will always recommend him.
Having Michal service my boiler and fix my shower was a joy. I felt completely at ease in the knowledge that he was totally honest and totally completely. Thank you.
I was fortunate to have this gentleman attend to problems on my boiler. He had to fit new parts and deal with faulty plumbing. His work is 5 star gold and an extra bonus he is the most perfect gentleman. I would heartily recommend him to anyone looking for a plumber - first class service.

Common questions about plumbing and heating
Dropping boiler pressure is often caused by a leak in the system, a faulty pressure relief valve, or recently bled radiators. Check for visible leaks around radiators and pipes. If you can't find the issue, call us for a professional diagnosis.
This typically indicates sludge buildup in your radiators. The sludge settles at the bottom, preventing hot water from circulating properly. A power flush service can resolve this issue and improve your heating efficiency.
Kettling sounds are usually caused by limescale buildup or a faulty thermostat. While not immediately dangerous, it reduces efficiency and can damage your boiler over time. We recommend a professional inspection to prevent costly repairs.
To keep your new boiler's warranty valid, it must be serviced annually. This also ensures safety and maximises efficiency. Our service includes a visual inspection, flue test, gas pressure check, safety device testing, and cleaning of key components.
Turn off the gas supply at the meter immediately, open windows and doors, don't use electrical switches or naked flames, and call the Gas Emergency Service on 0800 111 999. Then contact us for repairs once safe.
A straightforward boiler replacement typically takes 1 day. If it's a new installation or requires pipework changes, it may take 2-3 days. We'll provide a clear timeline during our initial assessment.
A power flush is a deep clean of your central heating system that removes sludge, rust and debris from your radiators and pipework. You probably need one if your radiators are cold at the bottom, your boiler is making banging noises, or your heating takes a long time to warm up. It restores efficiency, reduces energy bills and extends the life of your boiler. Our power flush service starts from £430.
On a combi boiler, heating working but no hot water usually points to one of three things: a faulty flow switch (the boiler doesn't detect you've opened a hot tap), a blocked plate heat exchanger (limescale preventing heat transfer to your hot water), or a faulty diverter valve that's passing (the valve that switches between heating and hot water isn't closing fully). All three require a Gas Safe engineer to diagnose and repair. Call us on 07900 247 384 for a same-day diagnosis.
On a system or heat-only boiler with a hot water cylinder, if your heating works but you have no hot water, the problem is usually outside the boiler itself. Common causes include: a faulty two-port or mid-position valve (not directing hot water to the cylinder), a faulty programmer or timer (not calling for hot water), or a faulty cylinder thermostat (not telling the system the water needs heating). These are straightforward repairs for a qualified engineer — give us a call and we'll get your hot water running again.
