Comfort Home Package

We have created the COMFORT HOME range, allowing homeowners to compare the most popular Combi boilers on the UK market suited to properties with one bathroom and an ensuite. These boilers come with 7-10 years parts & labour warranty as standard and at least 12 months of homeowner help and support from our friendly staff.

The COMFORT HOME Range range allows you to choose a boiler output (kW) suited for your property. The average-sized properties requiring a little extra power the 28–32kW options are more than powerful enough to supply 1 shower with hot water and another hot tap/washing machine at once.

Most manufacturers aim their boilers at this market so we have listened to our customer’s needs and included three choices within this package.

The Vaillant Eco Tec Pure range ( 8 series ) has been Vaillant’s most popular model boiler for many years. With 7 years manufacturers warranty as standard, you now have the option to upgrade to 10 years when installed by us as a Vaillant Advance installation company.

The Glowworm Energy C range is the flagship model for this brand and is popular with householders who don’t want to break the bank but have the extra reassurance of a guarantee of up to 10 years and with the added benefit of being under the umbrella of the Vaillant Group.

The Atag ic range sits very well in this category as even it is entry-level has the excellent build quality of the premium range of boilers but without the super-efficient flue gas heat recovery device. With an impressive 10 year warranty and lifetime heat exchanger replacement guarantee its certainly a model you may want to consider.

Updated review:

It is now 2 years since the new boiler was installed by Matt and his team. The boiler has performed flawlessly and we have found our gas bills are much lower than with our old system. Matt services the boiler for us every year and is always a pleasure to deal with. Cannot speak highly enough of this firm, they do great work and we highly recommend them.

Review from 2023:

On 9th & 10th March 2023. I had a Potterton Suprima & Gledhill Boilermate 2000 replaced with an ATAG Economise IC39 combi boiler. Matt & Dan arrived early and worked flat out over the 2 days. They were professional, friendly and did an outstanding job for us. Our system was badly gunked up and by the end the water in the system was sparkly and our home is now super warm. I cannot recommend Matt & Dan highly enough, we are delighted with the work they have done.
Response from the owner:Thank you David for your 5 star review The ATAG Economiser 39 with the smart controller and outside weather compensator is Europes most efficient boiler so you are heating your house at a fraction of the cost it was before. Early discussions indicated that having the option to run two showers at the same time was very important to you and after our initial calculations the atag has delivered that for you. The Boiler Replacement Company
A now occasionally leaking, 35 year old cast iron central heating & hot water boiler sited in an upstairs bedroom cupboard with a vertical flue through the loft and roof needed replacing.

After replying to a phone message promptly, and assessing the situation quickly, Mat Baker from The Boiler Replacement Company (Essex) Limited suggested a new Worcester Bosch boiler sited in the garage below, with a new flue outlet in the pitched roof over the garage. Once installed by a registered fitter and if annually serviced, the boiler came with a 10 year manufacturers guarantee. Due to their ages, a new pump and three port valve were also to be replaced in the existing cupboard.

Work started promptly on the allotted date with Mat & Dan in attendance, and within 2 days of their hard work starting (especially removing the old, heavy boiler) in the hot summer of 2025, we have a new, quiet and efficient system up and running.

A very clean, tidy and efficient job throughout. Thoroughly recommended.
Response from the owner:Hi Chris, Thanks for the great review! We’re glad we could replace your old boiler and install your new Worcester Bosch system quickly and smoothly. It’s always good to know our customers are happy with a quieter, more efficient boiler. Appreciate the recommendation and choosing The Boiler Replacement Company in Essex! Best regards, Mat – The Boiler Replacement Company

The review below was written after my new boiler was installed by Essex Boiler Replacement. Mat was back again today to service and check my boiler, the fourth consecutive year and as usual was punctual, very professional and efficient as well as being very friendly and amiable. I have no hesitation in endorsing my review and would highly recommend Essex Boiler Replacement for any boiler related work.Paul Wilson 6/3/25.

Very impressed with all aspects of having my boiler replaced by Mat. I was offered several options of boiler manufacturer. Installation was prompt, efficient and safe especially in view of current Covid-19 situation. Great care was taken to protect work areas and any mess was cleared.

I was recommended to Mat by a neighbour and would not hesitate to make a recommendation to use him to anyone needing this type of work.
Response from the owner:Thank you so much, Paul! It’s always a pleasure looking after your boiler, and I really appreciate your continued trust over the years. I’m so pleased to hear you’ve been happy with both the installation and the ongoing servicing—your kind words mean a lot! A big thank you as well for your recommendation. It’s great to know that word-of-mouth brought you to me, and I’m always happy to help. See you at the next service! All the best, Mat
We moved our boiler from a cupboard upstairs to a new boiler in our kitchen, this week. The whole process from start to finish was straightforward easy and completed in less than two days. Communication was great and also any questions we had were answered promptly. We had an extremely good service from the boiler replacement company and would highly recommend them. We would defo use them again in the future.

Work completed in a very tidy manner, and everything working perfectly.
Would definitely use again.
Response from the owner:Thank you for your 5-star review glad we could help with your new ATAG combination boiler
I would 100% recommend The Boiler Replacement Company. They did a fantastic job, were on time both days and were only too happy to answer any questions and offer advice in-person or by phone.

In the build-up to the installation our old boiler broke completely. Matt came over and got it going so me and my family had enough hot water to last us until they could come and install the new one.

Top service!

Response from the owner:Thank you Chris for the 5-star review glad we could help
We had an excellent experience with the Boiler Replacement Company Essex. We had our 20 year old floor standing boiler that was situated in the loft, replaced with a new Valiant ecofit pure 430. Matthew took the time to explain why he recommended said boiler and saved us money as I was pushing for a bigger boiler which he explained why we didn’t need. Good communication, clean, neat and tidy job, started and finished as agreed. Very knowledgeable and professional. All paperwork, regs and warranties sent immediately. They did a great job and would recommend highly.
Response from the owner:Thank you Colin for the 5-star review Not only do we aim to provide every house with an efficient boiler option but we also aim for 100% customer satisfaction
