Initially to reduce my personal carbon footprint and because I feel  owning a house carries a duty of improving it for people who will live in it in the future. But after a while I realised that doing this myself means I can support and inspire other people to try similar things, and this has also become a motivator.

Property background:

When I moved in, beyond partial very poor quality double glazing, nothing noticeable had been done to the house, which was cold.

Key changes made:

External wall insulation; internal wall insulation; underfloor and loft insulation; new efficient boiler; thermostatic radiator valves; low energy light bulbs; photo voltaic panels.


Full details of measures installed:

  • 100mm of phenolic board as external insulation – it was a cold solid walled house.
  • TLX silver on inside of bedroom and kitchen outer walls and underfloor downstairs.
  • 200mm of rockwool on top of the old 750mm fibreglass loft insulation, and when the bay window was reroofed I had it insulated with Kingspan insulation.
  • Triple glazing on 4 windows and secondary glazing made of Perspex and reclaimed timber on 2 others.
  • New condensing gas Baxi boiler with TRVs and a portable Honeywell thermostat.
  • Extractor fan in the bathroom.
  • 225kWp photovoltaic solar panels on the roof.
  • Rain water collection to outside recycled plastic waterbutts from the main roof, bike racks made of reclaimed timber bolted to front drive.
Measures installed in detail:

  • Condensing boiler with TRVs
  • Draught proofing
  • External wall insulation
  • Floor insulation
  • Internal wall insulation
  • Low energy lighting
  • Low energy appliances
  • Loft insulation
  • Roof insulation
  • Solar PV
  • Triple and secondary glazing
  • Water saving devices
Benefits of work carried out:

The house feels much warmer even when heated to the same air temperature as before the work was done. It’s also much drier, and as a result what was a mould problem is no longer apparent. The photovoltaics generate considerably more energy than the house uses in a year, and I only spend about £300 per year on gas and electricity combined.

Favourite feature:

EWI – warmer, drier and I no longer live with a substantial mould problem. It even made the house more attractive.
