personally speaking have always been happy with the service the GRO gives and in many years never an issue,
as far as i know the certificate side is self-financing, it's all the other services connected that cost the money,
not sure if the family records centre etc are also part of the finances,
i can't imagine the huge costs to run all these departments/buildings and if they have to increase prices so be it,
and my days on this planet i am not going to stress over a couple of quid extra if i want a record of someone 100+ years etc is a small cost (again my own opinion)
never seen many people kicking up a stink over Ancestry charging £20 a pop and another £10 for a 2nd copy of same certificate, so if you click on buy record on their site for 3 certs, a nice £60 (£90 if you want 2 of each)
and i would hate to think the amount of people that do it because they don't know otherwise.
I still think at nearly £10 a certificate is vfm, can't think of many things in 7 years ish that havn't jumped in price, excluding thing like electrical items that have dropped due to technology and demand, and we have to remember that family history is still for the minority. People in Australia etc pay exactly the same price as us for the same service, do we penalise them for for living elsewhere, my own opinion no.
The majority of British people will never have a clue about prices of certificates, never visit family record centres, or the National Archives etc etc and probably don't care, again the cost to run and hold and maintain all these records must be VERY high, so if it helps in the slightest way to keep our history then i am happy it is done.
