bOnline UK Pricing (2026): £7–£19.95/User, Billed Annually

On its cheapest plan that covers ten seats, bOnline lists £7.00 per seat per month on annual billing. For ten seats that is £70 a month, or £7.00 per seat once three years of billing and any setup fee are counted.

The published figure is the one we compute with; no separately labeled monthly-billing rate is published on the page we read.

Plan	Published seat price	On	Monthly billing	Min seats	Effective / seat at 10 seats	As published
Starter	£7.00 ex VAT	annual billing	—	—	£7.00	Pricing page: "only £7.00 /user/mo +vat". Plan page shows 36 / 24 / 12 months tabs with the same £7.00 on each. Legal note on the plan page: "New customer offer. Digital phone line starter £7.00+vat per seat per month with a 12-month contract. All prices are exclusive of VAT at 20%." Comparison table on the same page: "Contract 12 months". Month-to-month price not published. Terms: "each April the Charges will increase by the amount communicated to you"; "thirty (30) day trial" (trial signup: "bOnline phone trials only work in the UK").
Unlimited Calling	£13.95 ex VAT	annual billing	—	—	£13.95	Pricing page: "only £13.95 /user/mo +vat", "Unlimited UK landline & mobile calls*" (asterisk footnote not shown on the page). Plan page shows 36 / 24 / 12 months tabs with the same £13.95 on each. Legal note on the plan page: "Digital phone line with unlimited calls £9.95+vat per seat per month 6-month promo offer with 12-month contract reverts to £13.95 after, or 12-month promo, reverts to £13.95 after with a 24-month contract. All prices are exclusive of VAT at 20%." The £9.95 promo is not shown on the price card, so £13.95 is used. Adds call recording on-demand vs Starter.
AI For Business Calls	£19.95 ex VAT	annual billing	—	—	£19.95	Pricing page: "£21.95" struck through, "only £19.95 /user/mo +vat", "Most Popular". Plan page (/ai-call-recording-c/) has no contract-length tabs and no legal note, so the contract term for this plan is not stated (Starter and Unlimited Calling state a 12-month contract). Unlimited Calling plus AI call recording, transcription, scoring and search; recordings stored for 1 year.

UK providers do not publish on the same basis. Figures here are exactly as published; where the provider states the basis we print it. At 20% VAT an ex-VAT figure is 1.2 times higher on the invoice, so an ex-VAT price and an inc-VAT price are not comparable as printed. We do not convert between them.

What it costs as the business grows

Effective cost per seat per month over three years, by the number of seats you actually have. Where a plan has a minimum, the minimum is billed and the cost per seat you use rises. “n/a” means the plan is not available at that size. checked 2026-09-05

How that is worked out

seats billed = max(seats you have, minimum seats the plan requires) plan per month = published seat price x seats billed three-year cost = plan per month x 36 + setup fee effective per seat = three-year cost / (36 x seats you have) monthly-billing gap = monthly-billing price / annual-billing price flat package = flat monthly price + (seats billed - users included) x additional-user price add-on plans = shown on the provider's page, never ranked (they are not a phone system on their own) calls not included = shown on the provider's page, never ranked (calls are billed per minute, or sold as separate call packages, on top of the seat price) plan at each size = the cheapest plan that covers that seat count; a plan with a user cap hands over to the next one

Nothing else is added. Taxes, regulatory recovery fees, USF and e911 charges are not added to any figure on this site. On taxes and regulatory fees, 2 of the 37 providers state that the price already carries them on at least one plan, 0 publish what they come to, 14 say they are extra without an amount, and 21 say nothing. Where a provider says the price is all-inclusive or includes them, the page says so beside the figure; everywhere else the invoice will be higher than the figure. Where a plan needs another subscription first (a Google Workspace or Microsoft Teams license), that subscription is not in the figure and the page says so. Handset purchases, number porting, international calling and overage are excluded. Every figure here is a floor. The full method is at Method.

Taxes and fees

bOnline says nothing about taxes or regulatory fees on its pricing page. checked 2026-09-05

No figure on this page includes taxes or regulatory fees. This provider does not say on its pricing page whether they are added, so we treat them as unknown rather than as zero. In the United States those charges are real and recurring, and they land on the invoice rather than the pricing page.

Every provider's entries, by month, with an RSS feed: What changed.

Who owns it

Who owns this company is not stated on its own site, and we could not confirm it from a primary source. We have left it blank rather than repeat what other sites say.

Where this leaves you

If the three-year seat cost is what matters, Voipfone works out at £5.00 on the same basis — compare the two.
Do not treat any of these as the invoice: bOnline says nothing about taxes or regulatory fees on its pricing page, so we treat those charges as unknown, not as zero — what providers do and do not say about fees.

Who this page is not for

This is not a review. We have not used bOnline, we hold no opinion on its call quality or its support, and nothing here is a recommendation. It answers one question: what the published price turns into per seat over three years.
