Official inflation edged higher in the year to July as housing and household services led the rise. Ofgem has confirmed a further domestic price-cap increase from 1 October. Local firms should treat the household cap as a demand signal, not a ceiling on typical business tariffs.
Two official releases now sit side by side for autumn planning: the Office for National Statistics (ONS) Consumer Prices Index for July 2026, and Ofgem’s confirmed domestic energy price-cap levels for 1 October to 31 December 2026. Together they matter for Colchester and wider Essex because they shape household budgets (and footfall) while commercial contract renewals continue to set many firms’ own energy lines.
What the ONS said for July
The ONS reports that CPI rose by 2.9% in the 12 months to July 2026, up from 2.6% in June. That was the first rise in the annual CPI rate since March 2026. CPIH, which includes owner-occupiers’ housing costs, rose by 3.1%, up from 2.8%. On a monthly basis, CPI rose by 0.3% in July 2026.
Core CPI (excluding energy, food, alcohol and tobacco) was unchanged at 2.6%. Goods inflation rose from 1.7% to 2.2%; services inflation eased from 3.6% to 3.4%. Housing and household services were a major driver of the higher annual rate, with the previous Ofgem domestic cap uplift that took effect in July a key contributor. Food inflation eased to 1.3% from 1.7%. Restaurants and hotels inflation was 4.0% in the year to July.
These figures remain above the Bank of England’s 2% CPI target. The ONS release is national and does not publish a Colchester-specific inflation rate.
What Ofgem confirmed for October to December
On 26 August 2026, Ofgem announced that the domestic energy price cap for 1 October to 31 December 2026 will rise by about 4% for a typical dual-fuel household paying by Direct Debit. Under Ofgem’s updated Typical Domestic Consumption Values, the illustrative annualised bill moves from £1,663 to £1,723 (about £60 a year, or roughly £5 a month, if that level were sustained for a full year).
Ofgem attributes the rise mainly to higher wholesale gas prices linked to the Middle East conflict. The government’s removal of VAT from qualifying domestic electricity bills from 1 October 2026 to 31 March 2027 is already reflected in the published rates; gas continues to attract 5% VAT. Electricity bills for capped customers should stay broadly more stable than gas. Around 35% of households on fixed tariffs (about 11 million households, on Ofgem’s figures) are not affected by the default-tariff cap change until their fix ends.
Domestic cap versus business tariffs
Ofgem is explicit: the price cap limits unit rates and standing charges on domestic default (standard variable) tariffs. It does not apply if you have a business energy contract, are on a fixed domestic deal, use heating oil, or take heat from a heat network.
That distinction is central for Colchester hospitality, retail and light industry. Pubs, restaurants, hotels, cafés, high-street shops and workshops on commercial meters negotiate or roll onto business tariffs. Those rates are not capped by the £1,723 illustrative household figure; out-of-contract or deemed commercial rates can be expensive and remain uncapped.
Ofgem notes that the electricity VAT change can benefit some small businesses already eligible for reduced domestic VAT treatment on electricity. That is a narrow eligibility point, not a general business price cap. Most local firms should assume their energy cost is set by their contract, while the household cap mainly affects staff and customer living costs.
Cost-base implications for three local sectors
Hospitality. Energy (cooking, refrigeration, laundry, heating and lighting) is a material overhead alongside labour and food. National restaurants and hotels inflation at 4.0% shows catering prices still rising faster than headline CPI. A further household cap rise into the high-use winter quarter can squeeze discretionary dining even if a venue’s own meter is uncapped. Operators in Colchester town centre, the Hythe and coastal Essex should stress-test winter covers against softer household cash, without inventing a local sales figure the ONS has not published.
Retail. Shop energy use is usually lower than hospitality per site, but margins are thin and customers feel the domestic bill first. Soft goods and comparison retail on the high street and at Tollgate-style parks are exposed to any squeeze on real incomes. The July goods uptick reminds that shelf prices can firm even when food inflation eases.
Light industry. Process heat, refrigeration and shift lighting mean energy is often a larger share of cost of sales than in retail. Because business tariffs are uncapped, renewal timing matters more than the household headline. Firms around Severalls, Northern Gateway and smaller estates should treat the October domestic rise as a signal of wholesale pressure still feeding commercial quotes, and should document renewal dates rather than wait for a business “cap” that does not exist.
What is still uncertain
August CPI is due on 16 September 2026 (ONS, 7:00am), the day before the Bank of England’s rate decision. Wholesale gas remains volatile; Ofgem will next update the domestic cap for January to March 2027 by 25 November 2026. No Colchester-specific series here quantifies how many local firms renew energy contracts this quarter; this desk does not invent one.
The practical split is clear: use the ONS July CPI and Ofgem October domestic levels to judge household demand and staff cost-of-living pressure, and use your own commercial energy contract to judge site energy cost. Mixing the two produces the wrong budget.
