There’s a community scheme in my area where they’ve taken a sample for each house type and estimated costs to bring your house up to different standards, i think they’ve given three examples for each house type from just insulation up to everything including heat exchangers, led lights etc...

I don’t have the document in front of me but if your interested I can get it out and post some info later this evening.

That would be great, in your own time.

Many of you might be in similar situations to my folks.

From my parents experience.

House was built in 1990. Had standard cavity walls and single glazed windows. Wooden single glazed front and back door.

Open fire with back boiler heated sitting room, the radiators and hot water tank.

Storage heaters x3 heated house during the morning and early afternoon till fire was lit in the evening.


A few years ago around within a few months

They upgraded all windows and doors to uPVC double glazed

Had the little ball insulation pumped into cavity walls.

Replaced open fire with a stove with back boiler.

Put solar panels for heating water on the roof.


The plan at the time was in winter stove provide hot water and in summer hot water off the roof.


After all that my Dad does not have facts and figures but found

In the stove he burns 55 to 65% of the coal logs etc he burned in the open fire. Gets more hot water too.

Because of the double glazing/insulation the house is warmer in the morning so the storage heaters have not been turned on since.

Even in winter solar panels heat water - not warm enough for a shower say - but means stove has less work to do heating radiators etc.

In summer my Dad goes walking or cycling and around 15:00 hrs has a bath to use up the water. By evening the tank is full again. If you don't use the hot water the tank fills and it's release is to turn on the radiators. Imagine 20 degrees outside and the radiators are on in the house.


His recommendation for upgrades in order (based on cost and ease to install against benefits)

Stove. Glass and door stops heat rising up chimney after fire is out.

Windows and doors.

Wall insulation.

Solar panels.


Other benefits from the upgrades besides less coal etc and less electricity on storage heaters

Less damp on the walls in colder corners of the house.

Less noise from traffic etc.

Less dust etc when cleaning stove.

Increased security on window and doors with double/triple locking points.

Any questions give me a shout.

PS: Before anyone slags off storage heaters. My Dad worked for the ESB so got the storage heaters cheap and had reduced bills. Worked fine for us at the time.

Some notes on the above:
Heat recovery ventilation is very difficult to retro-fit. In theory it is extremely efficient (although older systems result in a BER penalty as the motor is running 247), but to successfully install you need a 100mm duct from every room going to a riser duct up to the motor. Which means a lot of alterations to the interior of your house if you have a standard wood joist floor/ceiling construction (otherwise the ducting can only travel the same direction as the joist runs). You also need to close up all vents in the house and seal trickle vents in windows. (The system works by mechanically managing a houses ventilation by drawing on natural sources of heat (cooker hood, utility and assited heat) and (without mixing the air) preheating the fresh air that is fed into the house).
The locking down of specialists that is manufacturer driven is a disgrace and obviously an easy adoption for insurance companies to help manage their own exposure.
Lastly "mickey mouse" jobs as you put it, or unskilled labour to the rest of us, are exactly the types of jobs we need to create. They take people off the dole, keep people out of criminal activity and contribute greatly to the coffers and community. They also are an entry level job for some who have a passing interest in construction but not the confidence or means to pursue a career adjacent to engineering.

Upgrade 1: indicative E1 to D1 approx. cost 2700 EUR
Roof insulation at ceiling level (increase up to 300mm)
Pump insulation into cavity wall (front)
Heating controls & minimum 80mm lagging jacket for hot water tank
Low Energy lights
Optional step A
Draught proof exterior doors
Draught proof hot press pipholes, attic hatch door, install chimney balloons
Optional Step B
upgrading existing glazing with low e glass
Optional Step C: partial internal/external wall insulation for select colder rooms

Pump insulation into cavity wall
external insulation to side and rear walls
install new double glazed windows (U=1.4) and new doors
condensing boiler and heating controls & min 80mm lagging jacket to 50mm spray on Hot water tank
new wood stove

turns out that this document is about 2 years old, so estimates may be out of date - I have not included the grants as I think they have changed since and am not sure what they are.

hopefully this helps though

This kind of gets to the heart of a lot of the problems with green policy. Who's paying and for what? There's a actually a perfectly reasonable rational for only giving a VAT discount to registered installers(fraud) and an assurance that they're giving a discount for the desired outcome. Recycling being a case in point which has been almost completely pointless in the case of some waste. A lot of it gets burnt or landfill...........

This is the problem govts are wrestling with the world over. Who pays for what(either directly or via subsidy) and for what desired outcome. IIRC Obama subsidezed a solar panel co that went bust which has been used as a stick to beat the green agenda in the US(not hard tbh). If govts give easy subs they create an expectation of easy subs elsewhere and bads subs generally set back the agenda.

I'm not questioning your commitment to doing it right, you're clearly considering your options and what you should do or spend etc to help. But you're in a minority. Research I saw from a few months ago suggesting that people talk big but shy away from doing anything. My current gf has taken a run at "low carbon" make-up removing pads. They're crap. She's persisting for the moment, but the case is weak so she'll probably go back, and they generally don't do well even in the demo that talks the most about climate change. Right across the board this is what happens. The big personal changes people make in terms of choices will be a slow burn mostly driven by changing norms over decades.

I may have generalised a bit too much on the government employment schemes but specifically, regarding insulation, they haven't a leg to stand on.
Reduce VAT to zero on insulation products and let that be that. If it turns out to be one of the worst decisions ever made then reapply VAT.
