The total market value of all goods and services produced within the political boundaries of the UK during a given period of time, were usually it's calculated on a quarterly basis.  The GDP is usually looked at as the official measure to the health of an economy as it reflects the nation's productivity. GDP is divided among personal consumption, investment, net exports, and governmental spending as follows:

GDP = C + G + I + NX

where:

"C" refers  to all private consumption, or consumer spending, in a nation's economy; this includes most personal expenditures of households such as food, rent, medical expenses and so on but does not include new housing.
"G" refers to the sum of government spending; from salaries to the public sector to military purchases expenditure; the measure does not include transfer payments such as social security or unemployment benefits. 
"I" refers to the sum of all the country's businesses investment in capital; spending by households on new houses for example is also included in Investment. 'Investment' in GDP is specifically identified as non-financial product purchases. 
"NX" refers to the nation's total net exports of goods and services minus total imports, since they are already included in C, I, or G thereby should be deducted to not count foreign supply as domestic (NX = Exports - Imports)

Commonly data are complied and released by the UK Office of National Statistics on a quarterly basis coming out 3.5 weeks after a quarter has ended, usually reported in "real" terms, which is economic growth minus the effect of inflation. The reading is released throughout the course of the quarter revised at least two times until the final reading; the sequel starts with the Advanced Estimate, then the Preliminary Reading, and then the Final Reading.

The GDP is considered a very important indicator that moves the currency markets hectically for the value of such a reading.  The reading is merely a reflection of a certain economy's performance in a specified period of time; therefore any improvement reflects the wellbeing of the economy in all its considered aspects. Consequently, a revitalized economy is reflected positively on the currency providing strength and demand on that currency.

The GDP reflects the markets' cycle that is starting by the consumer with increased income and high confidence in the economy would likely rise the level of spending therefore production levels increase resulting in rising employment increasing by that the  availability for more cash to spend empowering the cycle of production, which in result ends by empowering the currency.

The effect as mentioned is positive on the currency and direct; as for the equity markets the effect is towards the upside as well for the unbreakable tie that links any economy to the equity market, if there is growth there is defiantly an increase in the equity as well for it is a reflection of the output of that economy. Therefore any increase in the GDP affects positively the currency as well as the equity market and the opposite of this is as well applicable.
