Boiler house condensing boiler-any advice as regards brands?

Hi folks,
Was told that this post is more suitable for this forum, rather than "In my Home" forum
I'm in the initial stages of researching an oil filled boiler house condensing boiler to replace an old 30 year cast iron boiler (burner was replaced about 20 years ago) all working well at the moment, but as I understand it, will probably use a fifth more oil, and oil as you know is not cheap at the moment.
Lots of ads on tv for Grant boilers, but plumbers and the service guy have mentioned Warmflow and Firebird to me. How do they stack up against the Grant brand? Just don't want to buy and probably pay more for hype alone, and it has probably worked in my case seeing all the ads as I am swayed towards the Grant brand.
Idea's and any advice gratefully appreciated.
Many thanks.
A few pics of old boiler looks like a Neca midy (not much info o nnet about it)

Parts were getting harder to find, it was located inside our kitchen and it's theoretical efficiency was 70%. I suspected the true efficiency was probably less.
After investigating several boiler manufacturers I decided on a Grant Vortex Blue external unit. The cost of the Grant was pretty similar to other brands, but it came with a 10 year parts AND labour guarantee. (Subject to being fitted with a magnetic inline filter and having an annual service by a Grant approved engineer). 10 years peace of mind on unplanned expenditure is important to me. The new boiler has a claimed efficiency of 94.6%
We are now one year in and it has performed faultlessly. Based on measuring our oil consumption using an accurate in-line flow meter, I think we are using a massive 30% less oil than before, with no change to the hours of operation or room thermostat setting. I probably need to track this over a longer period as I'm not sure if this winter has been colder than the last couple.
We also changed the hot water and central heating circuits to motorised valve control which I think has helped with efficiency. The old system relied solely on thermal circulation to indirectly heat the water in the immersion cylinder. When set to hot water only, the upstairs radiators used to get warm due to the thermal circulation through the system unless we turned the radiator thermostatic valves right down.
After the installation was completed, I spent some time fine tuning the boiler thermostat setting, balancing the radiator flows and adjusting the circulation pump speed so I could achieve around a 20% differential between flow and return temperatures, with a return temperature of around 45C. This should help the boiler to condense efficiently.
Hard to say how much of the savings have been generated from the increased boiler efficiency vs installation of the motorised valves, but I'm not complaining. Especially with the recent increase in oil cost.
The fact that it is now outside has made the kitchen a lot quieter, given us a cupboard back and we no longer have any kerosene smells in the room!!
