In direct answer to your questions
Are the listed points consequences of the ECHR?
In a matter of speaking, yes, they are. As is shown below; the ECHR was written, in part, with reference to previous legislation which was in force in the UK since the 17th Century. Once the ECHR was agreed, it was
brought into an updated 1998 law (effective from 2000).
would they apply in Britain without the ECHR?
Yes, they would as the recomendations therein have already been written in to UK law.
European Convention on Human Rights
To take a quick run through your listed points (Source: http://www.echr.coe.int/Documents/Convention_ENG.pdf)
- The right to a fair trial
This is covered by Article 6: Right to a fair trial
In the determination of his civil rights and obligations or of
any criminal charge against him, everyone is entitled to a fair
and public hearing within a reasonable time by an independent
and impartial tribunal established by law [..] Everyone charged with a criminal offence shall be presumed innocent until proved guilty according to law.
This is covered by Article 8: Right to respect for private and family life
Everyone has the right to respect for his private and family
life, his home and his correspondence.
- Freedom from torture and degrading treatment
Covered by Article 3: Prohibition of torture
No one shall be subjected to torture or to inhuman or degrading
treatment or punishment
Covered by Article 9: Freedom of thought, conscience and religion
Everyone has the right to freedom of thought, conscience
and religion; this right includes freedom to change his religion or
belief and freedom, either alone or in community with others and
in public or private, to manifest his religion or belief, in worship,
teaching, practice and observance.
Covered by Article 10: Freedom of expression
Everyone has the right to freedom of expression. This right
shall include freedom to hold opinions and to receive and impart
information and ideas without interference by public authority
and regardless of frontiers
- Freedom from Discrimination
Covered by article 14: Prohibition of discrimination
The enjoyment of the rights and freedoms set forth in this
Convention shall be secured without discrimination on any ground
such as sex, race, colour, language, religion, political or other
opinion, national or social origin, association with a national
minority, property, birth or other status
Covered by Article 4: Prohibition of slavery and forced labour
No one shall be held in slavery or servitude. [..] No one shall be required to perform forced or compulsory labour
- Protecting Victims of Domestic Violence
This one is not explicitly covered, however many of the other Articles would seem to imply this. Such as Article 5: Right to liberty and security
Everyone has the right to liberty and security of person. No
one shall be deprived of his liberty save in the following cases and
in accordance with a procedure prescribed by law
- Peace in Northern Ireland
Again, not explicitly outlined in the ECHR (Why would it?) however, no doubt much of the appeasement of former combatants would no doubt have owed something to the promises of fair trials, and other protection from derogatory treatment.
Human Rights ACT (1998)
This legislation enshrined the recommendations of the ECHR into UK Law
An Act to give further effect to rights and freedoms guaranteed under the European Convention on Human Rights; to make provision with respect to holders of certain judicial offices who become judges of the European Court of Human Rights; and for connected purposes. (Source: http://www.legislation.gov.uk/ukpga/1998/42/introduction)
The full schedule of this act covers all of the points above as suggested by the ECHR.
1688 Bill of Rights
Before 1998 UK citizens had many of these same rights before the ratification of the 1998 law. Most of this is covered by the 1688 Bill of Rights
An Act declareing the Rights and Liberties of the Subject and Setleing the Succession of the Crowne.
(Yes, UK laws can be OLD! And I did not typo that quote. Language, like Laws, change over time)
