The Space Heating team - James, George and Dan - have been fantastic. We have an old property which needed a new boiler and some new radiators. We have had to do the work in phases and the team have been agile, pro active and very helpful throughout. They were sensitive to the old building and very respectful. They cleaned up after themselves each day and were very polite and friendly. The office team communicated regularly with us and ensured we were clear what was happening and when. We will most certainly be using them for the rest of the work in the house

Haven't used Space heating before but would definitely use them again. They advised me which type of boiler to have without any pressure. When they started the work the guys arrived on time both days. When doing the work they didnt keep popping out or chat all the time they just got on with it. Everything was left nice and tidy.

Premium cost, disappointing service
Customer Service
Quality
Value
Quoted £1,000 to supply and fit a radiator (a unit costing ~£200), and having paid a premium, top-quality workmanship was expected. The installer overlooked door clearance; it then took six weeks to rectify. The radiator remains uncommissioned, requiring either the hire of another plumber to complete the work or paying extra to this firm. For context, a radiator replacement in London typically costs £500-£800, depending on size and complexity. Overall, expensive service without matching quality - I will not use them again.

Thank you for your review. We’re sorry to hear your concerns and appreciate the chance to clarify. Customer satisfaction is important to us, as reflected in our other reviews. You expressed satisfaction with the work carried out and asked about the cost of a second visit. We confirmed there would be no charge for returning to reposition the radiator. The radiator was originally installed in the position you requested; the free revisit was provided to assist with the change in position. The price was fixed, as set out in our written estimate, and did not change at any point. We encourage all customers to obtain multiple quotes before proceeding. Our estimate stated we could either fill/commission the radiator or leave it empty to allow decorating, and that the estimate covered one visit. You chose to decorate behind the radiator first. At your request, we left the radiator connected with valves configured so your decorator could remove and refit it easily, without full system draining. Commissioning was not included or undertaken at that stage. We believe we acted fairly, professionally, and in accordance with your instructions and our written agreement. If you would like us to return to commission the radiator after decorating, please contact us and we’ll be happy to arrange this.

I have used Space Heating in the past for tap replacements and a previous radiator removal. So I had no hesitation in placing our current work request with them. Luke removed a radiator and capped the pipes below the floorboards. All work was conducted in a clean manner, taking care with carpets and furnishings. Luke ensured no air locks remained in the heating system and that radiators were functioning correctly. Excellent work with attention to detail. Thank you.

I just wanted to say a big thank you for arranging for Johnnie to come round to fix our sink. He was respectful, extremely polite and made sure my bathroom was tidier than it was from the beginning – most unlike any plumbers I have encountered before! I won’t hesitate in recommending him to others and I already have plans for a return visit to take a look at my shower.

Space Heating - Johnny Prosser review
Customer Service
Quality
Value
On 3rd January our central heating stopped working. The boiler seemed to be working ok and the hot water cylinder was full of hot water, but the pump that feeds the radiators wasn’t coming on. My wife phoned Space Heating Ltd and the hugely capable and knowledgeable lead engineer David paid us a visit that afternoon. He very quickly diagnosed the problem to be the valve and the valve mechanism that sits between the boiler, the pump and the hot water cylinder. He got the valve working again and restored our heating but said that it could go wrong again at any time and that the valve, the valve mechanism and the very ancient hot water cylinder should all be replaced. We received an itemised estimate for the work, which we accepted and the work took place on Thursday 16th January. We were very lucky to have the ever pleasant and friendly Johnny perform the work on our heating system. Johnny's work is exemplary. He scores 10 out of 10 on every front. His work is of the highest standard. He had to work in a tight space and removing the 40-year-old cylinder was tricky and time consuming. All the new bits were fitted and wired up in an orderly manner. Even though it was after 6 o’clock by the time Johnny had finished the installation, he still cleaned the areas that he had been working in, removed all debris and stayed on until he was 100% sure that everything was working correctly. You can’t get a better service than that.

After receiving very poor service and workmanship from other plumbing companies, I called Space Heating. They sent Harry to do the job. On seeing the issues he was able to quickly identify what needed doing and got the job done. He further assisted with installing an inlet valve to the cistern and replaced a number of iso valves that were leaking with quality ones I had bought. While doing the flush tests, a blockage magically appeared in the main waste pipe believed to have been created by previous plumbers. Once again, Harry worked quick enough resolve the blockage. Thank you.

An iterative quotation and design process over 8 weeks resulted in a Veissman system boiler with weather compensation, (wet) underfloor heating, new radiators and Heatmiser controls over three zones. This replaced a 40 year old system. It was a great company to work with. Installation took about a month and works to specification. Great installation team with amazing quality pipework and high standards of cleaniness when working in a confined space. I was really impressed.

Space Heating recently installed a new family bathroom for me. All aspects of the work (installation, plumbing, tiling, flooring etc.) were done to an extremely high standard. Everything was completed exactly to schedule, enabling us to plan around the inevitable disruption of not having a working bathroom for just over 2 weeks. Supply chain issues meant the shower tray and screen couldn't be delivered on time. Our plumber managed to source higher standard items at a better price, with delivery times that kept the work on track. We encountered some inevitable installation issues during the work - our plumber had some great alternative suggestions that proved better than the original plan. Thanks guy!

A big thumbs up for Space Heating: polite and helpful to deal with; arrived on time; knew what they were doing and fixed our heating problem with skill and efficiency, explaining things clearly. Pricing also seemed fair and competitive. And since they are a company with several teams rather than a one man band, they were able to help us speedily too. Already recommended to a friend who also had a good experience. Thank you!

I contacted Space Heating Thursday evening via the contact page on the website, they responded the next morning and booked me in for the following day. Very quick, professional service. Fouzia in the office was really helpful. Harry came out on Friday, cleared the drains within the hour and then helped resolve the issues I was having with the toilet seat. Harry made sure to tidy all areas before he left, was very friendly and helpful. Would absolutely recommend this company.

Space Heating Ltd, recently fitted a new boiler. From assessing the best options for us, to providing 2 quotes in very good time the work was underway 48 hours later. The engineers were fabulous, very friendly, very clean and tidy and impressively good at installing boilers and cylinders as well. First class. The office staff also deserve praise, alway answer phones promptly, provide quotations quickly and follow up once the work is done. A first rate business who have delivered us the boiler and heating system we wish we had 8 years ago! Highly recommended
