A 3 bed detatched will need a new condensing combination boiler installed.

You will be looking at around 2,000 to 4k really for that alone, so you don't want to be messing around with trying to keep your tank.

No it won't, a conventional boiler can be installed, it's up to the end user as to what suits their lifestyle best.
We don't even know if the flow rate is suitable for a combi.

and I’m pretty sure I've seen a condensing heat only back boiler although from memory it was on the expensive side.

bit of a balancing act between cost, space & mods need to fit a boiler elsewhere

If you would like to retain your hot water tank and airing cupboard, and don't have a need for hot water on demand 24/7, then why not just fit a conventional condensing boiler? I can't quite see the point of a combi in conjunction with a tank?

I didn't know there was such thing . Thought it had to be either a direct replacement for our old-fashioned back boiler or a combi. Please forgive my ignorance, and thank you one and all for all this really useful info.

What's that expression about a little knowledge being a dangerous thing?

Is it better to get an independent Gas Safe (think that's the title nowadays) fitter to advise, or stick with British Gas? Or is that an unanswerable question lol?

system isn't the same as back, see the link for the explanation of the differences.

combi is often confused for condensing, new standard boilers are condensing too.

All modern residential boilers have to be condensers (with very limited exceptions)-you don't have any choice there. But condensing boilers can be either combi's or conventional.
By all means use BG, but expect to pay up to 40% more. A local independent GSR who knows your model will be the best choice.

Don't assume that having a combi will remove the benefit of having an airing cupboard. Our Worcester Bosch Highflow 440 keeps the cupboard it is in very nicely aired.

That's strange, because your only other post this year clams that they are the best estate agents in London. Which is it?

It was a reply to a spammer (and not a very smart one) whose post has now been removed by the mods.

get a combi,

fit a small single panel radiator with trv,

in your airing cupboard,

unless you prefer stored hot water/and the fact that if a component on your boier failed you could switch your,
immersion heater on,till a fitter arrived with the offending part,
if thats the case,

you need a system boiler,with your existing cylinder with a s plan,
two ..... two port valves ....one for hot water one for heating,
wired into a ten way/ten chocolate blocks in a white plastic box,
chocolate blocks, are plastic strip conectors, with a screw at either end

change your radiator valves/and powerflush your system,
replace any knackered radiators eg, bathroom ones,
tatty bye :T i have not seen your hot water cylinder but i am sure its lovely,therefore i would go for the s plan and system boiler option pps dont forget your fernox f3 clean and drain and flush then f1 to preserve............
