Short answer

You can strip out, fit and level units, hang wall units, fit laminate or timber worktops, fit an inset sink and tap, and fit doors, handles, plinths and trims. You cannot do gas, notifiable electrical work, drainage alterations, or stone worktop fabrication. The middle ground is worktop joints and cut-outs, and that is where most self-fits go wrong.

Do this first

How do I measure my kitchen for new units and worktops?

Fitting your own kitchen is one of the largest sums of money a householder can save on a single project, and it is genuinely achievable. The reason it goes wrong is rarely the units — it is the worktop, which is expensive, unforgiving and cut once. Being clear about which parts to do and which to buy in is the whole of the decision.

Safety

Three parts of a kitchen fit are not yours regardless of skill. Gas work of any kind must be done by a Gas Safe registered engineer. New or altered electrical circuits in a kitchen are notifiable building work in England and Wales and must be certified by a registered electrician or by building control. Altering drainage or moving a soil connection is building control's business. Doing any of these yourself leaves uncertified work that is a safety risk and that surfaces at sale.

Step by step

Separate the job into the four regulated parts and the rest.Gas: Gas Safe registered, always. Electrical circuits and alterations in a kitchen: notifiable in England and Wales, certified by a registered electrician. Drainage alterations: building control. Stone worktop: fabricator. Everything else is available to a competent householder.
Be clear what notifiable electrical work means.A new circuit, or altering existing circuits in a kitchen, is notifiable building work and must be certified. Replacing a like-for-like socket faceplate is not. The certificate is what a buyer's solicitor asks for, so this is a paperwork question as well as a safety one.
Assess the unit fitting honestly — it is the easy part.Levelling units on legs, screwing them together, hanging wall units on a rail and fitting doors is careful, methodical work with no specialist tools. If you can build flat-pack furniture accurately and use a spirit level, you can do this.
Assess the worktop honestly — it is the hard part.A single straight cut in a laminate top is straightforward. A run with mitred joints, a sink cut-out and a hob cut-out, in an expensive top with no spare material, is where self-fits fail. The jig is hireable; the experience is not.
Consider the hybrid approach.Do the strip-out, the units, the doors, the plinths and the decorating yourself, and pay a fitter for a day to make the worktop joints and cut-outs. It costs a fraction of a full fit and it removes the single highest-risk element.
Count the tools you do not have.A long spirit level, a plunge router and a worktop jig, a good jigsaw with downcut blades, clamps, a basin wrench, a decent drill. Hire what you will use once; buy what you will use again. Attempting a worktop with the wrong tools is how the wrong outcome happens.
Count the time honestly.A professional fitter does a straightforward kitchen in three to five days. A competent householder working evenings and weekends should expect two to four weeks, during which there is no kitchen. That is the cost that people underestimate, not the money.
Check what the supplier's guarantee requires.Some kitchen suppliers' guarantees are conditional on professional installation, and appliance warranties commonly require installation to the manufacturer's instructions. Read this before deciding, not after.
Sequence around the trades you are buying in.The electrician needs the walls open at first fix and comes back at second fix. The Gas Safe engineer disconnects at the start and reconnects near the end. The stone fabricator templates after the base units and returns to fit. Book them around the sequence rather than the other way round.
Keep every certificate.Electrical certificate, Gas Safe paperwork, building control completion if anything was notified. Put them with the deeds. They are asked for at sale and reconstructing them years later is expensive and sometimes impossible.

Alternatives

Full self-fit: Everything except the four regulated items. Largest saving, longest disruption, and the worktop is the risk. Suits someone with the tools, the time and a tolerance for a fortnight without a kitchen.
Hybrid: self-fit with a fitter for the worktop: You do strip-out, units, doors, plinths and decoration; a fitter comes for a day to cut and joint the worktop. Removes most of the risk for a small share of the cost. The option most self-fitters should choose.
Supply and fit through the kitchen supplier: One contract, one point of responsibility, and the guarantee is intact. Most expensive, and the quality depends entirely on the fitter allocated.
Buy the kitchen, hire an independent fitter: Often cheaper than the supplier's own fitting, and you can choose the fitter on recommendation. You carry the coordination, and any dispute is between two parties rather than one.

Questions people ask

Can I fit my own kitchen?

Yes, apart from four things: gas work, which is Gas Safe registered only; new or altered electrical circuits in a kitchen, which are notifiable and must be certified; drainage alterations, which are building control's business; and stone or quartz worktop fabrication, which is done off site with wet diamond tooling.

Do I need building regulations approval for a new kitchen?

The units themselves are not controlled work. The electrics, any drainage change, ventilation and any structural alteration are, and that is what decides the answer for your particular job.

How long does it take to fit a kitchen yourself?

A professional does a straightforward kitchen in three to five days. A competent householder working evenings and weekends should plan for two to four weeks with no usable kitchen, and should plan the temporary washing-up arrangements accordingly.
