I am living in a large 5-bed period house with 2 bathrooms (one of which has an electric shower) and 17 radiators, so was looking for a powerful combi boiler that can giving enough heating output and at an affordable price. This is a big combi boiler with 7 yr warranty and 40kw output (and important 34kw CH output for all those radiators).
I decided to pair this up with a Salus programmable thermostat to control the boiler and thermostat. When you see that Worcester charge £200 for the equivalent Comfort 2 programmable thermostat, it puts into context what great value this is. Yes, it's not a fancy Nest or Hive programmable stat, and it's not a big name brand, but it works great.

This boiler comes bundled with a horizontal flue, mechanical clock, the Trappex pack, composed of a magnetic filter, cleanser and protector. You may wish to choose another filter (ADEY Magna products are very good). Note you can get this boiler for £900 from this company if you want a different filter & chemicals (but do make sure you buy a filter and get your system flushed and protected - it's a false economy not to do so): http://www.jtatkinson.co.uk/potterton-titanium-40kw-combi-erp-with-std-horizontal-flue-built-in-clock-7-year-warranty.html?gclid=CMuv24emzs8CFdU_GwodcAcMdw

Lastly, if you need new radiators I would recommend Brooklyn traders or Screwfix - have a search on HUKD for threads on these rad deals. They both have good prices for compact radiators. If you need TRVs (thermostatic radiator valves) and lockshield valves for your rads, you can typically get a twin packs for £7 each.
Really hope this deal helps someone as we get closer to winter and the cold bites. For working-class people that don't qualify for grants, haver a limited budget, and live in draughty big houses, this is a great deal. The equivalent Worcester setup (Worcester Greenstar 40cdi with Worcester comfort 2 programmable theormostat, worcester filter, adey cleanser and protector chemicals) is around £2200+.
Potterton is pretty much the same as Baxi (the Baxi 40kw equivalent is a bit more expensive). I would also heartily recommend the Ideal Vogue 40kw combi boiler which comes with a 10yr warranty. I find these boilers to provide excellent reliability and value. Worcester and Vaillant have a lot of hype behind them (they are both excellent, don't get me wrong), but these systems if installed properly should give you years of good service and are backed up with a solid warranty. Just ensure you get the boiler serviced once a year to maintain your warranty.
Please don't get cained off by exorbitant quotes from accredited installers (I am finding a lot of them to be extremely cocky these days .. give me a break with your constant complaining about having TOO much work, and trying to pull a fast one with your silly quotes), or utterly ripped off by British Gas!! British Gas quoted me over £10,000 (shame on you). If you have a trustworthy gas-registered engineer, you can purchase the materials yourself and agree a fair price with them for labour and required extras (copper piping, etc). You CAN get this type of work done well for a fair price - just be wise with your spend, don't take shortcuts, take your time and shop around for good materials and a good engineer to do the work for you. I am not an expert by any means (just a layperson sharing hours and hours of research done in the hope it helps someone in a similar position to me).
