IT Support Companies
IT Support Companies near you
IT support in the UK is sold in three broad shapes: a managed service billed monthly per user or per device, break-fix work charged by the hour, and co-managed support sitting alongside an internal IT person. The label matters less than the scope schedule. A managed contract that quietly excludes third-party applications, printers and the site you opened last month will feel like break-fix by the spring.

Whatever the shape, the provider holds administrator credentials to your email tenancy, your file storage and your network. That makes it a data processor for nearly everything it touches, which UK GDPR says needs a written contract with specific terms in it. It also makes the provider part of your attack surface. Cyber Essentials, the National Cyber Security Centre scheme, is the usual way UK buyers check a provider's own hygiene before letting it near anything.
Two things are worth settling before you sign: how fast someone answers as opposed to how fast the fault is fixed, and whose name the administrator accounts are registered in. Both cost nothing to agree at the start and are painful to unpick at the end.
How UK IT support contracts are structured
- Fully managed: a recurring fee covers monitoring, patching, helpdesk and a named list of systems, so the provider carries the cost of faults inside that list.
- Break-fix: you call when something stops working and pay for the time, which suits a very small office but gives the provider no financial reason to prevent the next fault.
- Co-managed: the provider covers out-of-hours cover, a specialist platform or project peaks while your own staff keep day-to-day control.
- Project work: a migration, an office move or a firewall replacement, priced separately from any ongoing agreement.
- Vendor-tied support: some firms only support the platforms they resell, which is worth establishing before you ask them to look at something they did not sell you.
Response time and resolution time are not the same promise
Almost every service level agreement promises a response, not a fix. A one-hour response can mean an automated email acknowledging the ticket. Ask for the definitions in writing: what counts as a priority one incident, who decides the priority, whether the clock runs only during contracted hours, and what happens when the fault sits with a third party such as your connectivity provider or a software vendor.
Resolution targets are rarer and usually conditional. Where one is offered, read what suspends it. Service credits are the normal remedy and are normally capped at a share of the monthly fee, so they compensate for irritation rather than for a day of lost trading. If an outage would genuinely stop you trading, the protection lives in your continuity plan and your insurance, not in the credits clause.
Cyber Essentials: the five controls your provider should already meet
The NCSC describes Cyber Essentials as the minimum standard of cyber security recommended by government for organisations of all sizes. It covers five technical controls: firewalls, secure configuration, security update management, user access control and malware protection. IASME is the NCSC's delivery partner and runs the scheme through a network of certification bodies.
Basic Cyber Essentials is a self-assessment that is independently reviewed. Cyber Essentials Plus covers the same five controls but adds independent technical testing to confirm they work on real machines, which is why buyers treat it as higher assurance. The NCSC also states that a UK organisation with turnover under 20 million pounds that certifies its whole organisation is included in cyber liability insurance arranged by IASME.
There is a procurement angle as well. Procurement Policy Note 09/14 requires suppliers to hold Cyber Essentials for central government contracts advertised after 1 October 2014 that involve handling personal information or supplying certain ICT products and services. If you bid for public work, the certificate is often what lets you answer the question at all.
Your IT company is a data processor under UK GDPR
In nearly every arrangement you are the controller and the IT company is the processor: it decides nothing about why your data exists, only how it is stored and moved. Article 28 then requires a written contract, and the ICO sets out what it must contain. Processing only on your documented instructions. Confidentiality obligations on anyone with access. Security measures meeting Article 32. Controls on engaging sub-processors. Help with individual rights requests. Help with breach notification, impact assessments and consulting the ICO. Deletion or return of the data at the end. And the right to audit and to be given the information needed to demonstrate compliance.
The contract must also record the subject matter, duration, nature and purpose of the processing, the types of personal data and the categories of people involved. Most providers offer a standard data processing agreement, so the useful reading is the sub-processor list inside it. Offshore helpdesks, backup vendors and monitoring tools all appear there, and any transfer outside the UK needs either UK adequacy regulations or a safeguard such as the International Data Transfer Agreement or the UK addendum to the EU standard contractual clauses, with a transfer risk assessment behind it.
What a proper onboarding produces in the first month
- An asset register listing every device, its operating system version, who uses it and when the vendor stops issuing updates for that version.
- A documented inventory of every system the provider will touch, with the licence holder and renewal date beside each one.
- Administrator accounts created inside your own tenancy in your organisation's name, with the provider given named accounts rather than a shared password.
- Written confirmation that domain names, DNS records and the email tenancy remain registered to your organisation.
- A baseline report covering patch status, backup results and any account holding more privilege than its job needs.
Changing IT provider without losing control of your systems
The commonest bad ending is not an argument about money. It is discovering that the outgoing provider registered your domain, your productivity tenancy or your backup account in its own name, so what should be a handover becomes a negotiation. Check the registrant details now, while nobody is annoyed.
Write the exit into the contract from the start: notice period, the format and timescale for handing over documentation, credentials and encryption keys, how long the outgoing provider will cooperate with the incoming one, and confirmation that your data is returned or deleted afterwards. Deal with backups explicitly, because a backup set is usually the last place your data survives after the relationship ends.
The routine work you should see evidence of
- Security updates applied to operating systems and to third-party applications, within a stated window, with evidence that they actually landed.
- Backups verified by restoring something, not merely reported as successful by the backup console.
- Multi-factor authentication on every administrator account and on all remote access.
- A quarterly account review so that leavers are genuinely disabled rather than left dormant.
- A standing list of any machine running software the vendor no longer updates, since nothing can patch it.
IT Support Companies: frequently asked questions
Is Cyber Essentials a legal requirement in the UK?
Not as a matter of general law. It is a certification scheme rather than a statute. It becomes binding through contracts: Procurement Policy Note 09/14 requires it for certain central government contracts advertised after 1 October 2014, and the NCSC notes that a growing number of organisations require suppliers to be certified before they can bid for work. Many insurers and larger customers ask for it too.
What does Cyber Essentials Plus add over the basic certificate?
The same five controls are assessed, but Plus adds independent technical testing carried out by the certification body rather than relying on a self-assessment questionnaire. In practice the assessor checks a sample of real devices and accounts to see whether the controls behave as described. That is why Plus is treated as the higher assurance option by buyers who care about the answer.
If our IT provider causes a data breach, who reports it to the ICO?
You do, as the controller. The ICO requires a notifiable breach to be reported without undue delay and no later than 72 hours after you become aware of it, with reasons given if that is missed. A processor that suffers a breach must inform the controller without undue delay so the controller can meet its own deadline. Put a concrete notification timescale in the contract, because the 72 hours runs against you, not against your supplier.
Should the IT company hold our domain name and email tenancy?
No. Register the domain, the DNS zone and the productivity tenancy in your organisation's name, with billing you control, and give the provider named administrator accounts within them. This costs nothing at the start and removes the single biggest source of leverage during a contract dispute or an untidy exit.
Does a small office really need a managed contract?
Not necessarily. The NCSC Small Business Guide is written for organisations with up to 49 staff and concentrates on backing up data, protecting devices, keeping accounts secure and recognising scams, most of which a competent office manager can arrange. A contract earns its keep when downtime costs real money, when you have compliance obligations to evidence, or when nobody internally can be responsible for patching.
Is there UK guidance for larger organisations with their own security staff?
Yes. The NCSC's 10 Steps to Cyber Security is written for medium to large organisations that have someone dedicated to managing cyber security, and it is a reasonable framework for briefing a provider on what you expect. The NCSC points smaller organisations without dedicated security staff towards its Cyber Action Toolkit instead.

What affects the fees IT support companies charge
Fees depend on the work involved and how the professional bills. We only publish fee ranges when they’re backed by real LokalMatch data or reliable sources. Until then, here’s what usually changes the fee:
- Scope and complexity of the work
- How the firm bills: hourly, per project or on a monthly retainer
- Experience of the team
- Timeline and how urgent the work is
- Ongoing support after the work is delivered
How to compare IT support companies before you hire
- Ask for examples of similar work for clients like you.
- Read reviews and ask for references you can contact.
- Make sure the scope, deliverables and timeline are written down before work starts.
- Ask who will do the work: an in-house team, freelancers or subcontractors.
- Compare two or three proposals before you decide.
Questions to ask IT support companies before you hire
- Have you done work like this before, and can I see examples?
- Who will work on this, and who is my main contact?
- How do you charge: hourly, per project or monthly?
- What is included, and what costs extra?
- How long is the contract, and how can either side end it?
- How will you report on progress?
- Who owns the work, files and accounts you set up for me?
Licences and registration
This kind of work is often limited to licensed or registered professionals, and the rules depend on where you are. Ask which body they’re registered with, and check their status on that body’s public register before you hire.
