Alec installed a Vaillant boiler with SensoComfort controls, as well as replacing our two old HW cylinders with a single large one. He understands how to get the best out of modern gas boilers, with features such as modulation and weather compensation, unlike most of the other people who quoted. This should give us reduced gas bills and a more reliable system. He was flexible and responsive to all of our concerns and requirements. He fitted the new boiler and equipment into the existing cupboards to maximise the usable space. He also noticed and fixed a leak which was causing damp issues. The job was finished on schedule and for the quoted cost. We are very happy with it and would definitely recommend Alec.

Alec installed a weather moderated, low loss header and sealed heating system - Vailllant boiler and controls. He has a firm grasp of current technologies, efficiency gains, environmental impact and legislation. Engaged in a timely manner from the off, quickly built our confidence in the proposed spec and quote. Installation was efficient and on time, involving us as needed. Alec also handled some unforeseen plastering, bringing in the tradesman needed - no hassle. We highly recommend.

The heating engineer fitted in a Viessmann Vitodens 200W boiler in our old house which previously had a redundant 23 year old boiler (spare parts no longer available) and which was becoming erratic, so we decided to replace it in Sep 2019. This meant having to set up a system using the current flue and chimney without too much upheaval, which is a taxing scenario in a listed property. Alec was the only engineer - of which I had consulted quite a few - who came up with a system that was more or less equivalent to the old. This is a reflection of his immense knowledge and understanding about heating systems, and what would work best. His recommendation came as a huge relief, as there is apparently nothing else on the market for our specific needs! Alec is thorough, communicates well (responding quickly to e-mails and phone calls), works hard and was always on time. He is also fun to have around the house, and I trusted him with my house-keys. If something went wrong, such as a small leak from the hot water cylinder, he attended immediately. The actual costs came below what he originally quoted for! The central heating system is a big success, keeping my house warm and toasty. I look forward to Alec doing the annual service of my boiler for many years to come.

Heating engineer was very knowledgeable about smart thermostats, weather compensation, modulation efficency and latest legislation/regulation requirements. They offered a selection of brands/models of boiler and controls with clear recommendations of which I chose Viessmann with Tado. Quote was provided promptly and comprehensive of all line items. Engineer was very flexible for installation date and fitted promptly with a clean installation and left the house tidy. Building Control certificate, warranty and invoice all received on the same day as installation. Final receipt received day after invoice paid.

After not being happy with a company I had used I chose Alec based on his reviews to put in a new Vaillant boiler. What a great choice. As someone else said he knows his stuff and is incredibly efficient and went above and beyond to help with various problems. I was very happy to have him working in the flat and would have been happy to leave him working had I needed to go out. If you need an engineer you really can’t go wrong choosing Alec. I really cannot fault him.

I asked Alec to service my boiler and advise on a couple of things with my heating. He had come earlier in the year when I was at my wits end of finding anyone who understood and could help me with my underfloor heating system with weather compensation. Alec did know how to make it work effectively. I am very grateful and pleased to have found him. Alec is clear about his charges and arrangements for making appointments. Good communications especially with texting. Has a very professional approach.

Alec has just replaced our boiler, cleaned out our system and installed a Tado smart system. He clearly knows his stuff, was very reliable, sent his quote when he said he would, came promptly and did the work quickly and efficiently. Highly recommended.

Alec Morrow has been working regularly for our family for 7 years, since 2011. Alec did an excellent job fitting a new central heating system for us in 2011, and has serviced it expertly every year since then. Alec always turns up when he says he will and investigates the system thoroughly, making sure it is both safe and fits the needs of our family. He really cares about doing the job properly and charges for the job rather than clock-watching. I first hired Alec because I wanted an engineer with genuine expertise and enthusiasm for saving energy and emissions. He was able to recommend a Remeha boiler, which I'd never heard of before, and install it, along with some new thermostatic radiator valves. Our home has been warmer and cheaper to heat ever since, with a control system that is easy to use. Alec also does gas safety checks.

Alec has recently installed in my flat a Vaillant EcoTech combi boiler with a Weather Compensator and I couldn’t be more pleased. His attitude to the work was most impressive: he was always punctual, straightforward and highly knowledgeable. The flat is now considerably warmer and the boiler is using much less gas than the old one. The controller gives me many options for timings and temperatures which will save me even more money. As a garden-flat it had a tendency to dampness but the new boiler has cured that. Helen of Highbury

Alec came to see me within 3 days of my email. He knew exactly what was needed to replace my ancient Gloworm boiler. He was back 10 days later with all that was needed. It was a tricky location but he worked away, sorting all the little difficulties. Two days for a big installation. Very pleased indeed. I now have a Eco-tech Valliant, with an outdoor thermo that is beautifully silent and has a perfect temperature. Programmable day to day or when you will be away. Finding out all sorts of new ways to save on the bills. Thanks Alec. He really knows his stuff! (PS I ran a well known consumer series on TV so, take it from me, Alec is a rare find!)
