We'll complete a detailed Technical Assessment to make yourhome Heat Pump Ready with SEAI design recommendations.

PageQuote Image

Your building fabric refers to structural materials, insulation, finishes, etc., that enclose the interior of your home, separating the internal from the external.

Upgrading the building fabric will reduce the heat losses through these elements and is best to be completed by taking a whole-house approach. This ensures that improvements are carried out in an organised, sensible order, with installations and refits complementing each other rather than working against each other.

Not all elements lose the same amount of heat or cost that same amount to upgrade, so it is sensible to recommend the measures that save the most and cost the least to begin with before including the items with the longer payback periods.

To make a house Heat Pump Ready, the following U-Value targets should be included as part of retrofit design recommendations, in line with backstop U-Values for existing dwellings as set out in TGD L Dwelling 2019.

Existing Buildings-Part L 2011

Building Element	Minimum U-Value
Ground Floor (No Underfloor Heating)	0.45W/m²K
Ground Floor (Underfloor Heating)	0.15W/m²K
External Walls (Cavity)	0.55W/m²K
External Walls (Not Cavity)	0.35W/m²K
Flat Roof	0.25W/m²K
Pitched Roof (Sloping Ceilings, Rafter Level)	0.25W/m²K
Cold Roof (Ceiling Level)	0.16W/m²K
External Doors, Windows, Rooflights & Curtain Walling	1.40W/m²K

Fabric First Approach

A ‘fabric first’ approach involves maximising the performance of the components and materials that make up the building fabric itself such as roof insulation, wall insulation, floor insulation and external windows and doors before considering upgrading mechanical or electrical building services systems such as your heating system.

This essentially reduces the amount of energy required to heat the dwelling at source...

Renewable Heating Second

The next stage of the retrofit design is to introduce renewable heating sources such as upgrading existing oil, gas and other fossil fuel heating systems to heat pumps, where possible, as a cleaner, more energy-efficient way of generating heat in a home.

Heat pumps are designed to deliver a consistent low level of heating that creates a very comfortable living environment. But, in order for heat pumps to operate efficiently, it is essential that all elements of the heating system are designed correctly...

Solar PV

Solar PV is an excellent way to further enhance the energy efficiency of your home and is usually one of the last measures that are recommended to be installed as part of your retrofit project. This is mainly due to the fact that greater savings are associated with completing the fabric and heating measures first before then adding renewable electricity to the design.

What Our Customers Say

We engaged Churchfield Home Services for external insulation and attic insulation on our 1950s semi-detached bungalow. From the very first communication we found Churchfield extremely professional and a pleasure to deal with. When Cosmin Luca, our project manager arrived onsite, no question or query was ever a problem, he was extremely prompt with all requests. Our work was carried out by Alex, who was a pleasure to have around, his attention to detail was incredible and he completed the work to the highest of standards. Our job has just been completed and the cold weather has arrived, straight away we have noticed a huge difference in the temperature in our house. We would highly recommend Churchfield Home Services to anybody looking for this service.

We were very happy with Churchfield. The initial consultations were clear and detailed, going through all elements of the work. They arranged a date with us, contacted us a week before to confirm and set out what would happen on each day of the first week, and stuck to what they said. The teams doing the work were excellent - fast, very high standard, and very clean and tidy. The administration team were very responsive to all our questions, and the project manager checked the work, spotted snags, and ensured everything was completed to a high standard. Would recommend to anyone.

External insulation. I highly recommend Churchfield and their team since they have worked in my house to provide us of external insulation. Since day 1 contact they have been highly professional, punctual and with quote really well explained and detailed. Communication is great from surveyor to project manager to sales advisor. Marius and his team take pride of their work and as such they build at perfection. They were very respectful, clean and they look at every detail, the project manager supervised and keep checking on the work progress all the time. This is my first time seeing worker leaving a place as they found it. One of the most professional team I have dealt in regard to builds. I would give them more starts if there were more. Thank you to all the team. My house is now cosy and looking amazing.
