Jobs a handyman can and can't legally do in the UK
A good handyman can turn their hand to a genuinely wide range of jobs, but UK law draws firm lines around certain types of work, particularly anything involving gas or notifiable electrical installations. Knowing roughly where those lines sit helps you brief a handyman properly, avoid wasting anyone's time, and steer clear of work that could leave you legally or financially exposed if it goes wrong.
Electrical work is governed in England and Wales by Part P of the Building Regulations, which splits jobs into notifiable and non-notifiable categories. Non-notifiable work commonly includes like-for-like replacement of sockets, switches and light fittings on an existing circuit, in rooms other than kitchens and bathrooms, along with general minor repairs that don't involve altering the circuit itself — this is the kind of work a competent handyman can typically carry out without needing to involve a registered electrician. Notifiable work is a different matter: new circuits, consumer unit changes, and fixed electrical installations inside a kitchen or bathroom are commonly treated as notifiable, meaning the work legally has to be either carried out and self-certified by an electrician registered with a government-authorised competent person scheme, or carried out by anyone else and then separately notified to, and signed off by, the local authority's building control team, commonly at a cost of roughly £150-£300 for the inspection. Skipping this step can leave you with an uncertified installation, which can cause real problems later, for instance when a buyer's solicitor asks for the paperwork during a house sale.
Gas work sits under an even stricter rule with almost no exceptions. All work on gas appliances, fittings and pipework in Great Britain must legally be carried out by an engineer on the Gas Safe Register, and this applies regardless of how confident or experienced an unregistered person might be. Carrying out gas work without being Gas Safe registered is a criminal offence, carrying penalties that can include an unlimited fine and up to six months in prison, and gas work done by someone unregistered is commonly excluded from home insurance cover as well, which matters enormously if something later goes wrong. A handyman who is not Gas Safe registered simply cannot legally touch a boiler, gas fire, gas pipe, or gas appliance, beyond the most minor day-to-day actions such as bleeding a radiator, and a reputable handyman will say so upfront rather than attempting the work.
Plumbing sits somewhere in between, and here a handyman genuinely does have more scope. Minor plumbing repairs — replacing a tap washer or cartridge, fixing or replacing a toilet cistern mechanism or seat, repairing a visibly leaking pipe joint or push-fit fitting, or swapping a kitchen or bathroom tap itself, as opposed to the supply pipe connections feeding it — are commonly regarded as within a handyman's competence and don't require a specialist. Bigger plumbing jobs, such as installing new pipework, working on a boiler, or anything connected to the gas supply, fall outside that scope and need a suitably qualified plumber or Gas Safe registered engineer instead.
Beyond electrics, gas and plumbing, most of what a handyman does day to day sits comfortably within their legal remit: carpentry and general repairs, furniture assembly, painting and decorating, hanging doors, fitting curtain rails and shelves, patching plaster, minor tiling, gutter clearing, and fence or gate repairs are all typical handyman tasks with no specific certification requirement attached. Anything more structural — removing a load-bearing wall, altering the layout of a building, or other work that falls under wider Building Regulations — generally needs its own approval process and professional input, and is worth flagging separately with your local authority or a qualified professional rather than assuming it's covered by a general handyman visit.
The safest approach as a homeowner is simply to ask directly: a properly run handyman business will tell you plainly whether a job is within their scope, whether it needs a registered electrician or Gas Safe engineer instead, and whether any paperwork such as a building control notification will be needed once the work is done. This article is general information rather than legal advice, and if you're ever unsure whether specific work is notifiable, or whether it needs a Gas Safe registered engineer, it's worth checking directly with a registered professional or your local authority before work begins.
Frequently asked questions
Generally yes — like-for-like replacement of sockets, switches and light fittings on an existing circuit, outside kitchens and bathrooms, is commonly treated as non-notifiable work that doesn't legally require a registered electrician.
No. All gas appliance, fitting and pipework must legally be carried out by an engineer on the Gas Safe Register, and doing gas work without being registered is a criminal offence with penalties that can include an unlimited fine and up to six months in prison.
Yes, minor plumbing tasks such as replacing tap washers or cartridges, repairing cistern mechanisms, fixing leaking push-fit joints, and swapping a tap itself are commonly regarded as within a handyman's scope.
It leaves you with an uncertified installation, which can cause problems later, for example when selling the property; notifiable work legally needs either self-certification by a registered electrician or inspection and sign-off by local authority building control, commonly costing roughly £150-£300.
