Where the money actually goes
It costs you £1,300 a year. Here is what that buys, what it saves, and the bit about tax that most pages would overstate.
The leak nobody mentions
Forget the broadband bill.
The money going out of your business is not on a comparison site. It is the hours you spend doing paperwork instead of the thing people pay you for.
Worked over 46 weeks, so your holidays stay out of it. You know your own diary better than any calculator does.
Those hours are worth
£12,420
a year, at your rate
Your admin hours are worth 9× what the service costs.
It is a business cost, like your van insurance
A service you buy to run the business is an allowable expense in the ordinary way, so you are not paying for it out of taxed money. Whether every penny qualifies depends on it being wholly and exclusively for the business, which for something like this it normally is.
What that is worth to you depends on how you are set up, and this is the part other pages skate over. If you are a sole trader it comes off your profit before income tax. If you run a limited company it comes off profit before corporation tax. The two are not the same and the saving is not the same.
Against hiring, the difference is not just the wage
Paying somebody £14 an hour does not cost you £14. There is employer's National Insurance on top, a pension contribution, holiday pay for 28 days, sick pay when it is needed, and the hours you spend running payroll and doing the paperwork that employing somebody creates.
None of that is an argument against hiring — a good person is worth it once you have enough work to keep them busy. It is an argument against pretending the comparison is wage against price.
What you actually get back
Time, mostly, and the receipts you would otherwise have lost. A receipt you cannot find is VAT you cannot reclaim, and for most trades that quietly adds up to more in a year than this costs.
Use the calculator above with your own numbers rather than ours. It is your hourly rate that decides whether this is worth it, and you are the only one who knows it.
One for your accountant
Nothing here is tax advice. What it comes to for you depends on how your business is set up and what else is in your accounts, and your accountant will tell you in about a minute. Anyone quoting you an exact saving without knowing either of those is guessing.
