Being UK citizen does not always mean you are UK Domiciled for UK tax purposes. UK Domicile is inherited on birth from English/UK father, generally, called 'Domicile of Origin' unless you have opted for UK 'Domicile of Choice' which is less likely.
Before I fully address your matter, I need few more details from you:
When did you buy this house?
Did you or your family always live in this house until you moved to Pakistan 3 years ago?
Do you have any other house in the UK?
Thank you and look forward to hearing from you.
Thank you for the info.
In this case, 'Domicile' is not an issue here, the issue is something called UK 'Ordinary Residence' for the purpose of UK Tax.
When you sell the house, generally it will be liable to UK Capital Gains Tax (CGT) on the gain. But, since you have always lived in the house (except last 3 years), the gain will be exempt anyway,
as the last 3 years will always be treated as 'deemed occupation' in the house by UK HM Revenue & Customs (HMRC) for the purpose of CGT, and so whole of the gain is exempt under 'Principal Private Residence (PPR) Exemption' rules.
Hope it helps.
As I stated earlier,

Based on the above, you may wish to confirm yourself if you are UK or Pakistani Domicile.
Internet Business in the UK:
As you said you have despatch office in the UK, HMRC is likely to argue that you are 'trading within the UK' (as opposed to 'trading with the UK'), and so UK business profit is likely to be within the scope UK Tax - regardless of your Domicile status,
unless you can demonstrate that you have no permanent establishment (PE) of business in the UK - for which, for example, you collect all orders over the internet, run internet business (process the order, receive the money etc) from outside the UK and despatch the delivery directly from outside the UK.
As you stated, where you have genuine and straightforward case, you can complete the relevant forms/details yourself and submit to HMRC as this will be cost effective although having professional adviser would always be handy.
With regards XXXXX XXXXX form - which form exactly are you referring to, I mean for what purpose precisely? Tax Return or Form to be Non-Dom or .......
Changing UK Domicile:
There is no single form as such to fill to change the UK Domicile straight to Non-UK Domicile. It is not like changing ' UK Residence' status.
Domicile is a matter of general law, not the tax law as such.
You can only change the UK Domicile after you had established/acquired new Domicile in another country.
