New Worcester boiler

honey06

Hi,
I need a new boiler and have had quotes for a Worcester combi. The current ancient ideal lives in a. Cupboard in the bathroom and has a 15mm feed pipe. The bathroom also has marble tiles and underfloor heating so obviously causing problems in changing to22mm. The bathroom is at the back of my terrace house and the gas meter is at the front- somewhere along the way it changes from 22mm to 15mm but isn't clear where.

House is a Victorian mid terrace, 2 beds, 1 bathroom, kitchen extended across back of house.

So I've had the following quotes:
1- Worcester accredited fitter- supply and fit 29cdi, inc power flush £2300 plus if needed, pipe work run along kitchen ceiling then up into bathroom to provide new 22mm feed quote 400-500. Can't do job for 2 weeks.

2- supply and fit 32cdi compact, inc power flush £2000. Said supply should be OK as current boiler is 30kw and ran ok and can't lift floor. Can do a week on Monday

3- British Gas supply and fit 30i £2546 or 29cdi £2589, power clean (not flush), Instal all pipe work required (22mm) hive thermostat. Can fit early next week. Plus homecare cover free for 1 year and boiler discount after that. The engineer suggested 30i better as marginally more efficient and smaller so would fit in cupboard better.


I'm currently without a boiler so no hot water/heating meaning the BG quote is very appealing. I was surprised it was quite competitive and the lady engineer was really helpful and took lots of time to talk everything through. I also like the Hive option. I liked the engineer in option 1 (local and recommended) but means waiting 2 weeks and could be the same price of slightly more than BG.

Thoughts please?

Also which if these different models should I go for?
And if I go with BG should I pay for a power flush (+£250) as well as the above?

You will have to have the gas pipe increased, no way around that. The old boiler burns poor gas so not so much of a problem, the new boiler will burner gas and oxygen mixed before the burner and it needs to be right. 15mm gas will not allow enough gas to the mix and the co readings will be all over the place.
